Nekuvandudzwa kwehupfumi hwekumaruwa uye kuwedzera kwehuwandu hwevanhu, kubuda kwetsvina yemumaruwa kuri kuwedzerawo. Kuti tichengetedze nharaunda yekumaruwa uye hutano hwevanhu, nzvimbo dzekuchenesa tsvina dzinofanirwa kuvakwa kuti dzigadzirise tsvina yemumaruwa. Township sewage chirimwa Integrated midziyo kwabuda panguva nhoroondo nguva, kuti basa rayo muitiro chaizvo sei, nhasi kunzwisisa.
Iyo yakabatanidzwa yemidziyo yetaundishipi yekuchenesa tsvina inonyanya kushandisa AO biological kurapwa maitiro kubvisa organic zvinosvibisa uye ammonia nitrogen. Nheyo yekushanda kwayo iri mukirasi A, nekuda kwehuwandu hwehuwandu hwezvinhu zvakasvibiswa mumvura yetsvina, ma microorganisms ari munharaunda ye hypoxia, panguva ino, ma microorganisms ari facultative microorganisms, anozoparadza iyo nitrogen organic musuweji muNH?-N, paunenge uchishandisa organic kabhoni sosi seanopa erekitironi, iyo NO?-N, NO?-N inoshandurwa kuita N? Uye kushandisa mamwe eiyo organic kabhoni masosi uye NH?-N kune synthesis yeiyo nyowani cellular material.
Naizvozvo, iyo kirasi A dziva reiyo yakasanganiswa sewage yekuchenesa michina haina chete Iyo imwe organic yekubvisa basa, kuderedza iyo organic mutoro weinotevera aerobic tank, iyo inobatsira kune nitrification, asi zvakare kuvimba nekuwanda kwehuwandu hwehupenyu huripo mu mvura mbishi kupedzisa denitrification, uye pakupedzisira kubvisa nitrogen eutrophic kusvibiswa.
Mukirasi yeO, nekuti kuwanda kwezvinhu zvakasikwa kwakadzikiswa zvakanyanya, asi iyo yakasanganiswa sewage yekuchenesa michina ichine imwe chiyero che organic zvinhu uye yakakwirira NH?-N iripo. Kuti uwedzere kuparara kweoxidation ye organic matter, uye pasi pekupedzwa kwecarbonization, iyo nitrification simba rinofamba zvakanaka, iyo aerobic biological contact oxidation tank ine yakaderera organic load inoiswa paO level.
Aerobic microorganisms uye self-oxygenic mabhakitiriya anonyanya kuwanikwa mukirasi O-dziva yemidziyo yakasanganiswa yekuchenesa tsvina. Ko aerobic microorganisms inoodza organic zvinhu muCO? Uye H? O, Inorganic carbon kana CO mumhepo? Sechitubu chinovaka muviri, NO mutsvina here?-N, NO?-N inoshanduka kuita N?. Mvura yemvura yeO pool inoyerera ichienda kuA pool, ichipa electron receiver yeA pool, uye pakupedzisira kubvisa kusvibiswa kwenitrogen kuburikidza ne denitrification.
Midziyo yakabatanidzwa yezvigadziriso zvemataundi ekuchenesa tsvina mumatunhu akasiyana zvinoda kusarudza tekinoroji yakakodzera yekuchenesa tsvina zvinoenderana nemamiriro ezvinhu ekumaruwa, uye inofanirwawo kufunga nezvekugoneka, hupfumi uye mhedzisiro yetekinoroji. Jiading kuchengetedzwa kwezvakatipoteredza kuchengetedzwa kwemidziyo yekuchenesa tsvina inogona kusangana nezvinodiwa zve 0.3-yakasanganiswa 10,000 matani ekuchenesa tsvina, uye 9 akatevedzana ezvigadzirwa anogona kusarudzwa zvakasununguka, zvichienderana neakasiyana mamiriro.
