Nekukura kwehupfumi hwemaruwa uye kuwedzera kwevanhu, kuburitswa kwetsvina yemumaruwa iri kuwedzerawo. Kuti kuchengetedzeke nharaunda yekumaruwa nehutano hwevanhu, nzvimbo dzakawanda dzekuchenesa tsvina dzinofanira kuvakwa kuti dzibate tsvina yemumaruwa. Midziyo yakabatana yemuchina wetsvina wetownship yakabuda panguva yenhoroondo, kuti maitiro ayo ekushanda anyatsojeka sei, nhasi uno.
Midziyo yakabatanidzwa yemuchina wekuchenesa tsvina yemuguta inoshandisa nzira yekurapa yeAO biological kubvisa tsvina yeorganic uye ammonia nitrogen. Nheyo yayo inoshanda iri mukirasi A, nekuda kwekuwanda kwezvinhu zveorganic mutsvina, tupukanana turi muchimiro chehypoxia, panguva ino, tupukanana tudiki tudiki, tunoparadza organic nitrogen mutsvina kuita NH?-N, ukuwo tichishandisa organic carbon source semupi wema electron, NO?-N、NO?-N inoshandurwa kuita N? Uye tichishandisa mamwe ma organic carbon sources neNH?-N pakugadzira zvinhu zvitsva zvemasero.
Saka, kirasi A yemidziyo yekurapa tsvina yakabatanidzwa haina chete basa rekubvisa tsvina, inoderedza mutoro we organic wetangi rinotevera re aerobic, iro rinobatsira pakuita nitrification, asiwo inovimba nehuwandu hwakawanda hwezvinhu zvipenyu zviripo mumvura isina kucheneswa kuti ipedzise denitrification, uye pakupedzisira kubvisa kusvibiswa kwe nitrogen eutrophic.
Mukirasi yeO, nekuti huwandu hwezvinhu zvipenyu hwakaderera zvakanyanya, asi michina yekuchenesa tsvina yakasanganiswa ichiri nehuwandu hwakati hwezvinhu zvipenyu uye NH?-N yakakwira iripo. Kuti zvinhu zvipenyu zviore zvakanyanya, uye kana carbonization yapera, simba re nitrification rinoenderera mberi zvakanaka, tangi re aerobic biological contact oxidation rine mutoro wakaderera wezvinhu zvipenyu rinoiswa padanho reO.
Zvipembenene zvinofefetera uye mabhakitiriya anozvigadzira oxygen anowanikwa mukirasi yeO-pool yemidziyo yekuchenesa tsvina yakabatanidzwa. Zvipembenene zvinofefetera zvinoora zvinhu zvipenyu kuita CO? Uye H? O, Kabhoni isina kuumbwa kana CO mumhepo here? Senzvimbo inovaka muviri, NO iri mutsvina here?-N、NO?-N ichashanduka kuita N?. Mvura inobuda mutsvina yeO inoyerera ichienda mutsvina yeA, ichipa electron receiver yetsvina yeA, uye pakupedzisira ichibvisa kusvibiswa kwenitrogen kuburikidza ne denitrification.
Midziyo yakabatana yenzvimbo dzekuchenesa tsvina dzemataundi munzvimbo dzakasiyana inofanirwa kusarudza tekinoroji yakakodzera yekuchenesa tsvina zvichienderana nemamiriro chaiwo enzvimbo dzekumaruwa, uye inofanirwawo kufunga nezvekugona, hupfumi uye kukanganisa kwehunyanzvi hwekuchengetedza tsvina. Midziyo yakabatana yekuchenesa tsvina yeJiading inogona kusangana nezvinodiwa zve 0.3-yakabatanidzwa matani 10,000 ekuchenesa tsvina, uye zvigadzirwa zvipfumbamwe zvinogona kusarudzwa zvakasununguka, zvichienderana nemamiriro akasiyana.
