Tichitarisa kubva kune ichangoburwa data rekutengesa, nhamba yemirairo yakagamuchirwa neLiding Environmental Protection yeAAO process michina inoramba yakakwira. Ndezvipi zvinhu zvinoita kuti vatengi vavimbe nemaitiro aya zvakanyanya? Tevere, Liding Environmental Dziviriro inosuma iyo yakakosha yeAAO maitiro.
Nheyo yeAAO maitiro ndeye kushandisa nitrification uye denitrification yezvipenyu pasi pemamiriro akasiyana-siyana kuti uwane kubvisa nitrogen, uye kushandisa phosphorus-kuunganidza mabhakitiriya kubvisa phosphorus. Naizvozvo, maitiro aya anonyanya kukodzera mapurojekiti ane kudzora kwakasimba kwenitrogen uye phosphorus zvinosvibisa. Mabasa makuru emidziyo yekuchenesa tsvina yekumaruwa yeAAO process akaiswa mumamodules matatu ekuita, ari anaerobic pool, anoxic pool uye aerobic pool.
Munzvimbo yeanaerobic reaction, nekuda kwekushaikwa kwenitrate uye oksijeni mutsvina yemidziyo yekuchenesa tsvina yekumaruwa, phosphorus inounganidza mabhakitiriya inochengeta simba mu phosphorus-inounganidza makomisheni uye inoburitsa phosphate radicals panguva imwe chete, nepo mamwe mabhakitiriya haashande. . Mune ino reaction module Mamwe mabhakitiriya haashande uye anonetsa kukura. Iyo anaerobic reaction module inoshandiswa kuderedza COD uye kugadzirira kubviswa kwephosphorus.
Mune anoxic reaction module, tsvina yemidziyo yekuchenesa tsvina yekumaruwa ine imwe nitrate isina oxygen, uye mabhakitiriya anoshandisa COD kuderedza nitrate kuita nitrogen, kuburitsa alkali, uye kuwana simba rekukura. Deredza COD uye nitrate nitrogen.
Iyo aerobic reaction module ndiyo musimboti wekuita nzvimbo yemidziyo yekumaruwa yekumaruwa yekuchenesa tsvina. Pano, mabhakitiriya ari nitrifying oxidize ammonia nitrogen kuita nitrate nitrogen, anoshandisa alkalinity uye oxygen, PAOs anonwisa phosphorus yakawanda, anoshandisa simba riri muPHAs kugadzira polyphosphorus, uye maOHO anoramba achibvisa COD, PAOs, OHOs, uye nitrifying mabhakitiriya anokura. mukuita uku. Deredza COD, ammonia nitrogen uye phosphorus.
Kubva pakuongorora kudiwa kwemapurojekiti ekuchenesa tsvina yekumaruwa, kusarudzwa kwemaitiro ekuchenesa tsvina kunofanirwa kusangana nezvinodiwa zvechiyero chekurapa, hunhu hwematsvina, kunaka kwemvura inoyerera uye kubuda kwemvura. Panguva imwecheteyo, nzira yakakodzera yekurapa inofanira kusarudzwa maererano nemaitiro emarara emunharaunda. Zviitiko zvakawanda zvinoratidza kuti AAO yekumaruwa yekuchenesa tsvina yemidziyo ine yakanaka kuchinjika kune akasiyana marudzi emapurojekiti.
