1. Inorganic impurities in water
Zaub greenhouses siv txia irrigation, feem ntau ntawm cov dej yog dej. Nws yog to taub hais tias lub rov tshwm sim ntawm high-flow manhole tus nqi, thiab ib co qhov dej nyob rau hauv lub siv ntawm ib lub sij hawm ntawm lub sij hawm tom qab qhov teeb meem no yuav tsum av nqu. Dej xuab zeb thiab gravel cov ntsiab lus nce, yuav undoubtedly nrog irrigation nrog qhov tshwm sim los ntawm plugging. Nyob rau hauv ib co chaw nplua nuj nyob rau hauv dej cov kev pab nyob rau hauv lub hauv av, nrog irrigation tsuas yog los ntawm dej hauv tus kwj dej, uas tseem muaj ntau ntau thiab tsawg xws li los ntawm inorganic impurities. Cov no yog thaiv cov hlab qhov culprit.
Solutions: Rau inorganic impurities dej ntau, kom tsis txhob plugging yuav tsum ntxiv dag zog rau cov dej lim. Nyob rau hauv lub qhov dej nyob installation ntawm loj-scale pom cov khoom, nyob rau hauv txhua lub tsev cog khoom teb xav tau rau nruab rau hauv lub lag luam los ntawm muaj zog monomer pom system. Xws li cov xuab zeb thiab gravel lim, laminated, mesh lim ua ke, dej zoo yuav ua tau tiav siv cov txheej txheem nrog irrigation. Yog hais tias nws yog pom tias thaiv cov hlab qhov teeb meem no tshwm sim nyob rau hauv lub plug qhov los ntawm qhov nyob rau tib lub sij hawm, peb yuav tsum qhib ib lub capillary los txhim kho lub dej siab los ntxuav lub impurities nyob rau hauv lub capillary.

2. Organic impurities
Rau ib txhia ntawm cov tshuaj chiv los yog lwm yam tshuaj kab mob ntiav Wells los yog dej kwj deg, organic impurities nyob rau hauv cov dej yog ib tug ntawm cov yog vim li cas tshwm sim los ntawm thaiv cov hlab lub qhov muag. Nyob rau hauv tas li ntawd, yog hais tias tus siv ntawm txia irrigation, qhov chiv yog tsis siv tom qab kawm tiav ntawm txaus dej yaug, yuav yooj yim ua rau ib tug ntau yam ntawm algae nyob rau hauv lub raj dej ib tug loj tus naj npawb ntawm cov yug me nyuam, uas yuav thaiv cov hlab lub qhov muag ntawm ib tug ntawm cov yog vim li cas .
Solutions: xaiv ib tug zoo zoo ntawm cov kua irrigation yeeb nkab, coj dub zaj duab xis nyob rau hauv cov kev tswj ntawm irrigation nyob rau hauv zaj duab xis. Muaj ob txoj kev los daws kom tau lub thaiv cov hlab ob lub qhov muag: Ua ntej, txoj kev siv cov acid rau ntxuav, tua yuav ua tau tiav, inhibition thiab tshem tawm ntawm algae thiab microbial nyhuv ntawm cov dej. Feem ntau siv perchloric acid, nitric acid, phosphoric acid, sulfuric acid, siv lub pH tus nqi rau 5.5-6.0, kev kho mob yuav tsum yog nruj me ntsis tshuaj concentration, kom tsis txhob raug mob rau cov qoob loo. Acid tu them xim rau tej lub system irrigation siab qeeb lub tus nqi ndlwg thiab txhim kho lub pickling nyhuv, tom qab qhov kawg ntawm yaug nrog dej. Qhov thib ob yog kev siv tshwj xeeb kom tsis muaj menyuam algicide yaug.

3. Dej thiab chiv
Siv txia irrigation chiv thaum chiv yog hais tias tus solubility yog tsis txaus los yog ntau tshaj impurities, nws yuav ua rau thaiv cov hlab ob lub qhov muag. Txawm li cas los, zaub teb kuj yuav tsum them sai sai mus rau ib tug teeb meem uas yog siv nyob rau hauv ib co zaub ntau lawm chaw ntawm av, calcium, magnesium thiab lwm yam hlau ion cov ntsiab lus yog high, lub carbonate cov ntsiab lus yog high, peb feem ntau yog hais rau cov dej zoo yog tus nyuaj, long-term siv nyob rau hauv Txia irrigation yeeb nkab phab ntsa los ua kom muaj ntau scale (calcium carbonate, etc.). Tej zaum kuj yuav sib xyaw nrog tshuaj chiv thaum lub nag lossis daus yuav tshwm sim, uas ua nyob rau hauv ob lub qhov muag thaiv cov hlab.
Solutions: Rau dej zoo zog qhov chaw yuav siv ion pauv dej purifier rau dej kev kho mob. Nyob rau hauv thiaj li yuav tiv thaiv tau cov tshwm sim ntawm chiv thaiv cov hlab lub qhov muag ntawm qhov teeb meem no, teb yuav tsum tau siv zoo zoo, siab solubility, tsis muaj residual dej-soluble chiv. Tam sim no nrog kev txhim kho ntawm cov dej-soluble chiv tsim txoj kev, cov kev siv ntawm ion kom technology nyob rau hauv cov dej soluble chiv ntsiab ruaj khov, yuav inhibit lub chiv thiab dej hlau ions muaj kev cuam tshuam los nag.
