Johkasou imichina midiki yekuchenesa tsvina yemumbainoshandiswa pakurapa tsvina yemumba yakapararira kana tsvina yemumba yakafanana, uye matangi akasiyana ane mabasa akasiyana, semuenzaniso: tangi rekuparadzanisa sedimentation rinoshandiswa pakurapa kwekutanga kubvisa zvidimbu zvesimba guru remagetsi uye zvinhu zvakasimba zvakamiswa, uye kuvandudza biochemistry yetsvina; tangi rekupfapfaidza rinenge rakashongedzerwa nezvizadza, uye pasi pekushanda kwe anaerobic biofilm pazvizadza, zvinhu zvakasikwa zvinonyungudika zvinobviswa; tangi rekupfapfaidza rinoiswa nemhepo, kumhanya kwekupfapfaidza kwakanyanya, Tangi rekupfapfaidza rinobatanidza mhepo, kumhanya kwekupfapfaidza kwakanyanya, kuchengetedza zvinhu zvakasimba zvakamiswa uye kushambidzwa kwemusana nguva dzose; nzvimbo inoyerera yetangi rekupfapfaidza ine mudziyo wekuuraya utachiona kuti ubvise tsvina.
Basa retangi rekuchenesa nderekuchenesatsvina yemumba, inova rudzi rwenzvimbo yekuchenesa tsvina inoshandisa tekinoroji yemuviri neyehupenyu kuchenesa tsvina yemumba zvinobudirira, ine simba guru rekuchenesa tsvina. Johkasou inonyanya kurapa tsvina yese yemumba yakadai sekicheni, yekugezera, yekuwachira uye yakafanana netsvina yetsvina kusanganisira tsvina yetsvina. Maumbirwo ejohkasouZvakasiyana, basa racho rakasiyanawo, kazhinji, johkasou inosanganisira kurapwa kwekutanga, kurapwa nemakemikari, kupwanywa kwemvura, kusefa uye kuuraya utachiona, mushure mekunge mvura yagadziriswa nejohkasou inogona kubatanidzwa kune network yemapaipi kana kuburitswa zvakananga kurwizi kana kumapurazi.
Mashandiro ejohkasou netangi remvura inoyerera (septic tank) ndeapi? Chekutanga, johkasou chishandiso chekuunganidza nekuchenesa tsvina, chinoshandiswa kuunganidza tsvina yemumba kubva muchimbuzi, mukicheni, mushawa, nezvimwewo. Tangi remvura inoyerera (septic tank) rine basa rekuunganidza tsvina kubva muchimbuzi chete. Chechipiri, johkasou inonyanya kushandisa tekinoroji yemuviri neyehupenyu kuti ichenese tsvina zvinobudirira, ichishandisa michina yekufema kuwedzera huwandu hweokisijeni yakanyungudutswa, kukurumidzisa kuumbwa kwebiofilm, nokudaro ichivandudza mhedzisiro yekuchenesa tsvina, tangi remvura inoyerera (sedimentation) ndiko kushandiswa kwesedimentation uye anaerobic fermentation kugadzirisa tsvina yetsvina.
Pamusoro pezvo, tsvina yemumba yekumaruwa inocheneswa netangi rekuchenesa inogona kusvika padanho reClass B muPollutant Discharge Standard yeMinda yekuchenesa tsvina yemumaguta(GB18918-2002), uye mamwe matangi ekuchenesa anogona kutosvika padanho reClass A, uye mhando yetsvina yetangi remaseptic inowanzo kuve muClass B standard muPollutant Discharge Standard for Urban Sewage Treatment Plants (GB18918-2002). -2002) muClass B standard kana pasi. Chinonyanya kukosha ndechekuti mutengo wakasiyana, mutengo wetangi rekuchenesa unofanirwa kunge uri 3,000 yuan, kana kutoti zviuru zvishoma zve yuan, uye mutengo wetangi remaseptic unowanzo bva pa500-2,000 yuan.
Saka zvichienderana nezvinodiwa zvakasiyana zvenzvimbo uye kugona kwemari kubhadhara, pakusarudza michina, unogona kusarudza zvinoenderana nezvinodiwa zvavo zve reagent.
