Kubva padata rekutengesa razvino, huwandu hwemaodha akagamuchirwa neLiding Environmental Protection yeAAO michina yekugadzira michina huchiri pamusoro. Ndezvipi zvinhu zvinoita kuti vatengi vavimbe nemaitiro aya zvakanyanya? Tevere, Liding Environmental Protection ichazivisa kukosha kwemaitiro eAAO.
Chinangwa chikuru cheAAO ndechekushandisa nitrification uye denitrification yezvinhu zvipenyu mumamiriro akasiyana-siyana kuti zvibvise nitrogen, uye kushandisa mabhakitiriya anounganidza phosphorus kubvisa phosphorus. Nokudaro, iyi nzira yakakodzera mapurojekiti ane kudzora kwakasimba kwenitrogen nephosphorus. Mabasa makuru emidziyo yekuchenesa tsvina yemumba yekumaruwa yeAAO anowanikwa muzvikamu zvitatu zvereaction modules, zvinoti dziva reanaerobic, dziva reanoxyic uye dziva reaerobic.
Munzvimbo ine anaerobic reaction, nekuda kwekushaikwa kwe nitrate neokisijeni mutsvina yemidziyo yekuchenesa tsvina yemumba yekumaruwa, phosphorus inounganidza mabhakitiriya anochengeta simba mu phosphorus-accumulating compounds uye inoburitsa phosphate radicals panguva imwe chete, nepo mamwe mabhakitiriya asingashande. Muchikamu chino che reaction mamwe mabhakitiriya haashande zvakanyanya uye akaoma kukura. Anaerobic reaction module inoshandiswa kuderedza COD uye kugadzirira kubviswa kwe phosphorus.
Muchikamu cheanoxic reaction, tsvina yemuchina wekuchenesa tsvina yemumba yekumaruwa ine huwandu hwakati hwe nitrate isina okisijeni, uye mabhakitiriya anobvisa nitrite anoshandisa COD kuderedza nitrate kuita nitrogen, kuburitsa alkali, uye kuwana simba rekukura. Deredza COD ne nitrate nitrogen.
Module ye aerobic reaction ndiyo nzvimbo huru ye reaction yemidziyo yekuchenesa tsvina yemumba yekumaruwa. Pano, mabhakitiriya anosimbisa anogadzira ammonia nitrogen kuita nitrate nitrogen, anoshandisa alkalinity uye oxygen, maPAO anotora huwandu hwakawanda hwephosphorus, anoshandisa simba riri muPHA kugadzira polyphosphorus, uye maOHO anoramba achibvisa COD, maPAO, maOHO, uye mabhakitiriya anosimbisa anowedzera kukura mukuita uku. Deredza COD, ammonia nitrogen uye phosphorus.
Kubva mukuongororwa kwezvinodiwa zvemapurojekiti ekuchenesa tsvina yemumba ekumaruwa, kusarudzwa kwemaitiro ekuchenesa tsvina kunofanirwa kusangana nezvinodiwa zvehukuru hwekuchenesa, hunhu hwetsvina, hunhu hwemvura inoyerera uye nzvimbo inobuditsa mvura. Panguva imwe chete, maitiro akakodzera ekuchenesa anofanira kusarudzwa zvichienderana nehunhu hwetsvina yemunzvimbo. Mimwe mienzaniso inoratidza kuti michina yekuchenesa tsvina yemumaruwa yeAAO inogona kuchinjika zvakanaka kumhando dzakasiyana dzemapurojekiti.
