1. Inorganic impurities in water
Muriwo greenhouses vanoshandisa donhwe kudiridza, vakawanda mvura mvura patsime. Zvinonzi kunzwisisa kuti chidzoke mukuru-aibuda manhole zvazvingava, uye mamwe matsime ari kushandisa nguva pashure mamiriro zvichabviswa mujecha. Water jecha uye mavhu kugutsikana kunowedzera, Achawedzera inodonha makomba kudiridza donhwe kunokonzerwa plugging. Mune dzimwe nzvimbo akapfuma mvura pfuma pasi, inodonha kudiridza kazhinji nemvura mukati canal, iyo rinewo hukuru zhinji kubvira inorganic tsvina. Ava ichivharira chaikonzera.
Solutions: Nokuti inorganic netsvina zvakawanda mvura, kudzivirira plugging kunofanira kusimbisa mvura firita. Mumvura iri kugadzwa pamwero mukuru filtration zvokushandisa, mune imwe neimwe girinihausi varimi vanofanira kuisa nokushanda nesimba monomer filtration hurongwa. Akadai jecha uye mavhu Sefa, laminated, pajira riya Sefa mubatanidzwa, mvura unhu zvinogona kuwanika kushandisa mureza donhwe kudiridza. Kana vakaona kuti rakanga rakavhara mamiriro ezvinhu kwakaitika chivhariso mugomba nepakaburi panguva imwe chete, tinofanira akavhura rirambe richibvira kuvandudza mvura nevezera kuchenesa netsvina iri rirambe richibvira.

2. Organic impurities
For mamwe makemikari fetiraiza kana zvimwe zvinhu utachiona kudzika matsime kana rwizi inoerera, makemikari kuchena mumvura mumwe zvikonzero kwakakonzerwa ichivharira meso. Uyezve, kana kushandisa donhwe kudiridza kwacho, kuti fetiraiza harishandiswi pashure pakupera zvakakwana mvura sukurudza, zvinogona kukonzera siyana algae nyore ari Mapaipi vazhinji maberekero, riri ichivharira maziso rimwe zvikonzero .
Solutions: sarudza unhu zvakanaka donhwe kudiridza mutopota, kutora dema firimu aidzorwa kudiridzwa pasi firimu. Pane nzira mbiri kugadzirisa ichivharira meso: Chokutanga, kushandiswa asidhi kuchenesa, disinfection inogona kubudirira, chinovhiringidza uye kubviswa algae uye microbial mugumisiro mvura. Yaiwanzoshandiswa perchloric acid, nitric acid, phosphoric acid, sulfuric acid, shandisa ph kukosha 5.5-6.0, kurapwa anofanira kuva zvakasimba kudzorwa wevasungwa, kudzivisa kukuvadza zvirimwa. Acid rokuchenesa Fungisisa achideredza hurongwa kudiridza kufurirwa kunetesa kuerera mwero uye uvandudze pickling Chaizvoizvo yapera sukurudza nemvura. Wechipiri kushandiswa unyanzvi mbereko algicide sukurudza.

3. Mvura fetiraiza
Kushandiswa donhwe kudiridza fetiraiza kana mupfudze kana solubility hakuna kukwana kana kupfuura tsvina, izvozvo achaita ichivharira meso. Zvisinei, miriwo varimi vanofanirawo kungwarira dambudziko rinoshandiswa dzimwe miriwo kugadzirwa zvinhu pasi, calcium, magnesium nezvimwe simbi Ion zviri kumusoro, asi carbonate zviri kumusoro, isu kazhinji kutaura mvura unhu achiri nesimba, kushandiswa refu donhwe kudiridza mutopota rusvingo kuti vaunze zvakawanda pamwero (karusiyamu carbonate, etc.). Rinogonawo hwakakanyiwa namakemikari fetiraiza apo kwemvura chichaitika, zvichiguma ichivharira maziso.
Solutions: Nokuti mvura unhu zvakaoma nzvimbo zvinogona kushandiswa Ion Exchange mvura purifier kunorapwa mvura. Kuitira kudzivirira panowanikwa fetiraiza ichivharira meso ezvinhu, varimi vanofanira kushandisa hwakanaka, mukuru solubility, hapana residual mvura-soluble fetiraiza. Zvino pamwe kuvandudzika mvura-soluble fetiraiza kugadzira muitiro, kushandiswa Ion activation michina mumvura soluble fetiraiza zvinhu yakatsiga zvikuru, vanogona tunodzivisa fetiraiza uye mvura simbi ions dzinoratidza kunayisa.
