Clogging agents tsis tshua ua hauj lwm ib leeg. Biological slime, los yog biofilm, ua zoo li cov kua nplaum ntuj hauv koj cov kav dej thiab cov emitters. Cov kab mob nyob hauv lub cev tsim cov txheej txheem nplaum no. Raws li dej ntws, biofilm no ntes cov khoom hla dhau zoo li cov xuab zeb thiab cov xuab zeb. Cov av khib nyiab muab ntau qhov chaw rau biofilm loj hlob. Lub biofilm ces ntes cov av ntau dua.
Qhov kev sib xyaw ua ke no ua rau cov tawv tawv, sib xyaw ua ke uas nyuaj rau tshem tawm ntau dua li slime lossis xuab zeb ib leeg. Nws tuaj yeem thaiv tus emitter sai sai. Kev ywg dej yooj yim feem ntau yuav tsis ua haujlwm. Kev rhuav tshem lub voj voog no yuav tsum muaj kev cuam tshuam nrog ob qho tib si lom neeg thiab lub cev.
Ⅰ. Proactive Filtration Strategies
Txoj hauv kev zoo tshaj los tswj cov dej drip dej kom zoo yog kom tsis txhob muaj kab mob kis mus txog cov emitters. Ib qhov zoo-tsim thiab tswj xyuas qhov system yog koj thawj thiab tseem ceeb tshaj plaws tiv thaiv.
⒈ Tsim Koj Cov Lim Lim
Tsis muaj universal filter solution. Qhov kev xaiv zoo yog nyob ntawm koj qhov chaw dej thiab cov khoom tseem ceeb uas koj tau txheeb xyuas.
Cov ntxaij lim dej ua haujlwm tau zoo heev rau kev tshem tawm zoo - cov lus hais zoo li cov xuab zeb zoo. Lawv tsis tshua muaj txiaj ntsig zoo rau cov khoom siv organic, uas tuaj yeem smear hla lub vijtsam.
Disc filters siv grooved, stacked discs los tsim ib tug peb -dimensional filtering txoj kev. Qhov no ua rau lawv zoo tshwj xeeb ntawm kev ntes algae thiab lwm yam khoom siv organic uas yuav nyem los ntawm lub vijtsam yooj yim.
Sand media filters yog qhov hnyav - txoj haujlwm xaiv. Lawv siv ib lub txaj ntawm cov xuab zeb uas tau muab qhab nia los ua ib txoj hauv kev uas cuam tshuam ntau cov organic thiab tsis yog - cov kab mob organic. Lawv yog qhov kev xaiv zoo tshaj plaws rau cov dej qias neeg nrog cov khoom siv roj ntsha siab.
⒉ Txoj Cai Saib Xyuas Kev Pom Zoo
Lub lim tsuas ua haujlwm yog tias koj tswj nws kom raug. Backwashing yog txoj haujlwm tseem ceeb tshaj plaws ntawm kev saib xyuas. Ntau lub tshuab muaj kev siv rov qab tsis siv neeg, tab sis phau ntawv tshuab yuav tsum tau ua tib zoo mloog.Nruab cov ntsuas ntsuas ua ntej thiab tom qab lim. Thaum lub siab sib txawv ntawm ob lub ntsuas ntsuas mus txog theem (feem ntau 8-10 PSI), nws yog lub sijhawm rov qab ntxuav.
Rau cov ntxaij lim dej thiab disc, koj xav tau kev tshuaj xyuas phau ntawv thiab tu. Sib cais lub lim dej thiab tshawb xyuas lub vijtsam lossis cov cartridges rau lub kua muag, kev puas tsuaj, lossis tawv tawv uas rov qab ntxuav yuav ploj. Ntxuav lawv nrog txhuam mos thiab dej.
Thaum kawg, teeb tsa ib lub sijhawm rau kev tso dej tawm. Qhov no txhais tau hais tias qhib lub kaus mom kawg lossis dej ntws tawm ntawm koj cov kab tseem ceeb, sub-mains, thiab lateral drip kab. Qhov kev txiav txim no tshem tawm cov av nplua nuj uas tau dhau los ntawm cov lim dej thiab nyob hauv cov kav dej. Qhov no tiv thaiv nws los ntawm puas mus txog cov emitters.
Ⅱ. Smart System thiab Fertigation Design
Kev tswj xyuas dej kom zoo mus dhau qhov pom. Kev tsim lub cev ntawm koj cov dej hauv dej thiab koj cov tshuaj tswj xyuas cov tshuaj yog qhov tseem ceeb rau kev tsim cov clog tiv thaiv txij thaum pib.
⒈ Tsim Clog-Resistant System
• Cov khoom uas koj xaiv thiab seb koj npaj lawv li cas cuam tshuam rau kev ua haujlwm ntev -.Kev xaiv emitter yog qhov kev txiav txim siab tseem ceeb. Pressure compensating (PC) emitters xa cov nqi ntws sib xws thoob plaws ntau qhov kev ntxhov siab. Qhov no yog ib qho tseem ceeb rau hilly struts los yog ntev khiav. Qhov tseem ceeb, ntau lub PC emitters kuj muaj tus kheej zoo tshaj -flushing mechanisms. Lawv nquag thawb tawm cov khoom me me thaum lub sijhawm pib thiab kaw. Tsis yog -pressure compensating (NPC) emitters yog yooj yim dua thiab tsis kim tab sis muaj feem cuam tshuam los ntawm kev hloov siab.
• Thaum txhim kho daim kab xev drip, xyuas kom cov emitters tig ntsej muag. Qhov no tso cai rau cov sediment nyob rau hauv txoj kab los nyob rau hauv qab ntawm daim kab xev, deb ntawm lub emitter txoj kev tau txais dej. Qhov no drastic txo cov feem ntawm lub cev clogging.
• System layout kuj tseem ceeb. Tsim koj lub cev kom tshem tawm "qhov kawg tuag" qhov twg dej tuaj yeem zaum thiab cov av tuaj yeem tsim. Txhua lub sub- txoj kab tseem ceeb thiab sab nraud yuav tsum muaj lub qhov dej ntws tawm lossis tshem tawm qhov kawg ntawm nws qhov deb tshaj plaws. Qhov no ua rau txoj haujlwm tseem ceeb ntawm kev yaug yaug sai thiab yooj yim.
Durable, zoo -engineered daim kab xev yog koj thawj tiv thaiv. Cov khoom zoo liSINOAH's Flat Emitter Drip Tapeyog tsim nrog cov yam ntxwv meej hauv siab. Qhov no ua rau muaj kev noj qab haus huv hauv lub sijhawm ntev -.
⒉ Cov Kev Cai Zoo Tshaj Plaws rau Fertigation
Fertigation yog kev xyaum siv chiv los ntawm kev siv dej. Nws yog ib qho cuab yeej muaj zog. Txawm li cas los xij, nws tseem yog ib qho tseem ceeb ntawm cov tshuaj lom neeg clogging yog tias tsis tswj kom raug. Peb yuav tsum ua raws li txoj cai nruj los tiv thaiv cov teeb meem no.
DO: Siv cov chiv soluble heev. Xaiv cov khoom tshwj xeeb uas tsim los siv rau hauv cov dej drip dej kom ntseeg tau tias lawv yaj tag.
DO: Ua ib qho "jar test." Ua ntej txhaj tshuaj chiv tshiab rau hauv koj lub cev, muab cov tshuaj sib xyaw ua ke hauv lub khob iav ntawm tib qhov kev xav uas koj npaj yuav siv. Cia nws zaum thiab saib seb puas muaj huab cua, cov khoom khib nyiab, lossis cov khoom tsim.
YUAV UA LI CAS: Txhaj tshuaj chiv los ntawm cov lim dej loj. Qhov no tso cai rau lub kaw lus pom kom ntes tau cov khoom uas tsis tau muab tshem tawm lossis cov khib nyiab uas npaj txhij txog ua ntej lawv nkag mus rau cov kab tseem ceeb.
DO: Flush lub system tom qab fertigation. Tom qab lub sijhawm txhaj tshuaj tiav, khiav lub kaw lus nrog dej huv rau yam tsawg 15-20 feeb. Nws yog ib qho tseem ceeb kom tshem tawm tag nrho cov chiv seem ntawm cov kav dej thiab cov emitters.
TSIS TXHOB: Sib tov phosphate lossis sulfate chiv nrog cov chiv uas muaj calcium lossis magnesium. Qhov no yog ib daim ntawv qhia classic rau kev tsim cov khoom uas yuav tsis yaj, zoo li calcium phosphate.
TSIS TXHOB: Nres lub voj voog dej tam sim tom qab fertigation. Tawm hauv cov concentrated fertilizer daws zaum hauv kab yog thawj qhov ua rau txhaws. Kev tshaj tawm - txhaj tshuaj yog qhov tsim nyog.
Ⅲ. Kev kho thiab kho cov tshuaj chlorine
Txawm tias muaj kev tiv thaiv zoo tshaj plaws, qee zaum clogging tuaj yeem tshwm sim. Thaum nws ua li ntawd, peb xav tau ib lub tswv yim meej, ua tau zoo los ntxuav lub kaw lus thiab rov ua nws txoj haujlwm. Kev kho tshuaj lom neeg muaj peev xwm ua tau zoo heev rau kev tshem tawm cov pob zeb hauv av thiab tshem tawm kev loj hlob lom. Qhov no tuaj yeem txuag tau ib qho system los ntawm kev hloov pauv kim.
⒈ Lub zog ntawm Acid
Kev txhaj tshuaj acid yog thawj txoj hauv kev los kho cov tshuaj clogs. Nws yog siv los yaj cov ntxhia nplai thiab deposits. Saib dawb, crusty nplai (calcium los yog magnesium carbonate) los yog reddish -xim av slime thiab stains (hlau los yog manganese oxides).
Ntau hom kua qaub tuaj yeem siv tau, suav nrog nitric, phosphoric, thiab sulfuric acid. Kev xaiv feem ntau yog nyob ntawm tus nqi, muaj, thiab tus nqi ntawm cov kua qaub.
Ua raws li cov kauj ruam no -los ntawm - cov txheej txheem rau kev txhaj tshuaj kua qaub kom nyab xeeb thiab zoo:
• Xam cov kua qaub uas xav tau. Lub hom phiaj yog kom txo cov pH ntawm cov dej nyob rau hauv lub irrigation system mus rau kwv yees li 2.0. Qhov no yuav tsum paub txog qhov ntim dej hauv koj lub cev thiab lub zog ntawm koj cov kua qaub.
• Sau cov dej los ntawm kev khiav dej num ib txwm muaj.
Txhaum cov kua qaub maj mam, feem ntau tshaj 30 mus rau 60 feeb. Saib xyuas pH ntawm qhov chaw txhaj tshuaj kom ntseeg tau tias nws tsis poob qis dhau sai.
• Kaw lub kaw lus. Cia cov kua qaub los zaum hauv cov kab rau "soak lub sij hawm" ntawm 1 mus rau 2 teev. Tsis txhob cia nws zaum ntev heev, vim nws tuaj yeem ua rau cov khoom puas.
• Ntxuav tag nrho lub cev nrog dej tshiab, huv si. Txuas ntxiv mus kom txog thaum lub pH ntsuas ntawm qhov kawg ntawm qhov kawg ntawm sab nraud rov qab mus rau qib qub ntawm koj cov dej.
CEEB TOOM TXOJ CAI: Ib txwm hnav cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), suav nrog cov kua qaub- cov looj tsom iav, hnab looj tes, thiab khaub ncaws tiv thaiv, thaum tuav cov kua qaub. Txoj cai tseem ceeb ntawm kev nyab xeeb yog ib txwm ntxiv cov kua qaub rau hauv dej, tsis txhob dej rau cov kua qaub, txhawm rau tiv thaiv cov tshuaj tiv thaiv txaus ntshai uas ua rau kub.
⒉ Kev kho chlorine
Rau cov kab mob uas muaj teeb meem los ntawm cov kab mob lom lom -algae, slime, thiab biofilm- kev kho tshuaj chlorine yog cov tshuaj zoo tshaj plaws. Siv txoj kev no thaum koj pom ib qho slimy, gel-zoo li cov khoom hauv cov kav dej lossis cov emitters. Qhov no qhia txog qhov teeb meem tseem ceeb ntawm biofilm lossis algae uas dej ntws ib leeg tsis tuaj yeem tshem tawm.
Peb tsom rau qhov tshwj xeeb concentration kom ntseeg tau tias muaj txiaj ntsig. Lub hom phiaj yog kom ua tiav cov tshuaj chlorine dawb ntawm 10-20 qhov chaw ntawm ib lab (ppm) ntawm qhov kawg ntawm txoj kab sab nraud.
Nov yog txheej txheem txheej txheem rau chlorination:
• Xaiv koj qhov chaw tshuaj chlorine. Cov kua sodium hypochlorite (xws li tshuaj bleach) los yog granular calcium hypochlorite yog cov kev xaiv.
• Pib txhaj cov tshuaj chlorine rau hauv lub cev thaum nws tab tom khiav. Ib ntus sim cov dej tom kawg ntawm kab nrog cov khoom siv tshuaj chlorine.Txuas ntxiv mus kom txog thaum koj ncav cuag lub hom phiaj ntawm 10-20 ppm.
• Kaw lub kaw lus thiab cia cov dej chlorinated zaum hauv kab. Lub sijhawm sib cuag ntawm ob peb teev, lossis ib hmos, feem ntau yuav tsum tau ua kom muaj txiaj ntsig zoo tua cov organic teeb meem.
• Ntxuav lub cev tag nrog dej tshiab. Txuas ntxiv yaug kom txog thaum tsis hnov tsw ntawm chlorine ploj mus thiab kuaj cov strips qhia tias tsis muaj cov tshuaj chlorine ntxiv. Qhov no yog qhov tseem ceeb ua ntej rov pib ua dej ib txwm, vim tias cov tshuaj chlorine siab tuaj yeem ua rau cov qoob loo.
CEEB TOOM: Tsis txhob sib tov chlorine thiab acid, thiab tsis txhob txhaj rau tib lub sijhawm. Qhov kev sib xyaw ua ke no tsim cov roj chlorine tuag taus. Yog tias koj yuav tsum tau ua ob qho tshuaj acid thiab tshuaj chlorine, xyuas kom meej tias lub kaw lus tau ua tiav thiab huv huv ntawm cov tshuaj thawj zaug ua ntej yuav qhia qhov thib ob.
Ⅳ. Kev Npaj rau Kev Sib Tw Dej
Kev tiv thaiv tus qauv ua haujlwm zoo rau qhov nruab nrab. Txawm li cas los xij, ntau tus neeg cog qoob loo ntsib qhov nyuaj tshwj xeeb hauv cov dej.
Scenario 1: Reclaimed Dej
Kev siv cov dej khib nyiab los yog cov dej rov qab los rau kev siv dej yog qhov kev coj ua zoo. Tab sis nws nthuav tawm qhov kev pheej hmoo siab tshaj plaws ntawm clogging. Cov dej no yog nplua nuj nyob rau hauv cov organic teeb meem, tshem tawm cov khib nyiab, thiab tej zaum cov kab mob.
Txoj kev kho ntau-theem yog qhov tsim nyog. Lub kaw lus yuav tsum pib nrog lub pas dej tso cai kom cov khib nyiab hnyav tawm. Qhov no yuav tsum tau ua raws li lub hauv paus xuab zeb media filtration unit los lis cov organic load siab. Thaum kawg, lub disc lossis cov ntxaij lim dej yuav tsum tau muab tso rau hauv qab yog qhov thib ob, lossis "thawj", lim kom ntes txhua yam uas lim xov xwm yuav nco.
Cov tshuaj chlorination tsis tu ncua dhau los ua txoj haujlwm tiv thaiv kev tiv thaiv, tsis yog kho- nws cov cuab yeej. Kev txhaj tshuaj tsawg - ib lub lim tiam lossis ob zaug -ib lub lis piam tuaj yeem txwv kev loj hlob ntawm cov kab mob lom ua ntej nws tau tsim.
Subsurface Drip Irrigation (SDI) feem ntau yog siv nrog cov dej rov qab kom txo tau tib neeg thiab qoob loo. Txawm li cas los xij, vim tias cov emitters raug faus thiab tsis tuaj yeem kuaj pom qhov muag, SDI xav kom muaj kev pom zoo thiab txhim khu kev qha thiab kev saib xyuas. Txhua qhov tsis ua haujlwm hauv qhov system yog qhov nyuaj dua los kuaj xyuas thiab kho. Ib txwm ua raws li kev noj qab haus huv hauv zos thiab ib puag ncig cov cai rau kev siv dej rov qab.
Scenario 2: Hard Dej thiab Organics
Lwm qhov teeb meem nyuaj yog kev sib xyaw ntawm cov dej tawv thiab kev ua liaj ua teb organic. Cov dej tawv yog siab hauv cov calcium uas yaj thiab magnesium, ua rau cov pob zeb hauv av. Organic chiv, thaum muaj txiaj ntsig zoo rau cov av, tuaj yeem ua zaub mov rau microbes, txhawb kev loj hlob ntawm biofilm. Qhov no tsim kom muaj cua daj cua dub zoo rau ob qho tib si tshuaj lom neeg thiab lom lom.
Peb tau tswj hwm ntau lub tshuab raws li cov xwm txheej no. Nws yuav tsum muaj kev tiv thaiv kev sib koom ua ke uas hais txog ob qho teeb meem tib lub sijhawm.
Qhov twg muaj peev xwm ua tau nyiaj txiag, ua ntej- kho cov dej nrog cov dej softener lossis cov tshuaj txias tuaj yeem tshem tawm cov calcium thiab magnesium ua ntej lawv nkag mus rau hauv lub cev. Yog tias ua ntej - kev kho mob tsis yog ib qho kev xaiv, npaj rau niaj hnub, tiv thaiv cov kua qaub. Ib qho tshuaj tsawg - noj cov kua qaub uas tau ua txhua hli tuaj yeem ua rau cov pob zeb me me ua ntej lawv tsim thiab tawv rau hauv qhov txhaws loj.
Thaum siv cov organic chiv, xaiv cov kua formulations nrog qhov tsawg tshaj plaws particle teeb meem. Nws tseem yog ib qho tseem ceeb rau nruab ib lub lim dej rau ntawm cov kab tshuaj chiv nws tus kheej kom ntes cov khib nyiab ua ntej lawv tau nkag mus rau hauv cov dej loj.
Kev tshaj tawm -fertigation flush yog qhov tseem ceeb hauv qhov xwm txheej no. Cov organic tebchaw yuav tsum raug tshem tawm tag nrho ntawm lub cev kom tsis txhob muaj cov kab mob microbes lawv cov khoom noj. Nthuav lub sij hawm yaug kom cov kab huv si.
Ⅴ. Xaus
Thaum kawg, qhov clog- tiv thaiv kab mob los ntawm kev npaj ua tiav. Tus tsim yuav tsum muab tag nrho koj cov kev mob tshwj xeeb. Tus qauv tsim yuav tsum suav nrog koj hom av, uas cuam tshuam rau cov qauv wetting thiab yuav tsum tau emitter spacing. Kev xaiv cov khoom yuav tsum yog raws li cov ntaub ntawv no.
