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 ne oxygen mutsvina yemichina yekuchenesa tsvina yemumba yekumaruwa, mabhakitiriya anounganidza phosphorus anochengeta simba mumakomponi anounganidza phosphorus uye anoburitsa phosphate radicals panguva imwe chete, nepo mamwe mabhakitiriya asingashande. Muchikamu chino che reaction mamwe mabhakitiriya haashande zvakanyanya uye akaoma kukura. Chikamu che anaerobic reaction chinoshandiswa kuderedza COD uye kugadzirira kubviswa kwephosphorus.
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 pakuongorora kudiwa kwevanhu vekumaruwakugadziriswa kwetsvina yemumbaMapurojekiti, kusarudzwa kwenzira yekuchenesa tsvina kunofanirwa kuzadzisa zvinodiwa zvehukuru hwekuchenesa, hunhu hwetsvina, hunhu hwemvura inoyerera uye nzvimbo inobuditsa mvura. Panguva imwe chete, nzira yakakodzera yekuchenesa inofanira kusarudzwa zvichienderana nehunhu hwetsvina yemuno. Mimwe mienzaniso inoratidza kuti michina yekuchenesa tsvina yemumaruwa yeAAO inogona kushandiswa zvakanaka kumhando dzakasiyana dzemapurojekiti.
