Sezvatinoziva tese, kucheneswa kwetsvina yemumaruwa kunoda kusanganiswa nemamiriro chaiwo ekugara kwevanhu kumaruwa kuti atore nzira yenzvimbo, uye panguva imwechete kuona kutenderera kwakanaka kwekushandisa zviwanikwa uye kudzora kusvibiswa. Kushandiswa kwezviwanikwa zvemumaruwa zvetsvina mushure mekurapwa zvine mwero kunogona kuderedza mari yekuchenesa tsvina, kudzokorodza zviwanikwa zvemvura zvekurima uye nitrogen uye phosphorus zvinhu, uye kushandisa zvizere zviwanikwa zvevhu rekumaruwa uye kuchenesa mvura nharaunda. Nekuda kwekukurumidzira kuvandudza nharaunda yekumaruwa, kushandiswa zvine hungwaru kwetsvina yemumaruwa yekumaruwa ichava chinangwa chenguva refu chekusimudzira kusimudzira kwekuchenesa tsvina.
Kushanda kwenzvimbo kunoda nekukasira kubvisa kufunga kwemukati
Parizvino, kurapwa kwetsvina yekumaruwa yekuChina, kunyanya kushandisa zvivako zvakabatanidzwa + nzira dzezvisikwa, asi kushanda kwezvivako hakuna tariro. Dzimwe nzvimbo dzekurapisa ndedzemudhorobha sewage plant 'miniaturisation', kuvaka, kushanda nekugadzirisa mutengo wakakwira, nzvimbo dzekumaruwa dzakaoma kubvuma, asi zvakare vakafuratira kushandiswa kwetsvina yemumba kuchengetedza basa rekuorera ivhu. Nekuda kwehuwandu hushoma hwehupfumi hwekumaruwa uye tekinoroji, huwandu hukuru hwemabasa ekuchenesa tsvina, zvekuti nzvimbo zhinji dzenzvimbo dzekurapa, pombi network haigone kuvaka, haikwanise, kushaikwa kwevashandi vehunyanzvi nehunyanzvi hwekugadzirisa. Mumamiriro ezvinhu aripo ekukurumidza kukurumidza kuguta, kucheneswa kwemvura yemumaruwa kunoda kudzikisa mitengo yakanyura senge zvivakwa uye pombi network, kubvisa kufunga kwemukati, uye kukurudzira zvakachipa, zviri nyore kuchengetedza mhando dzekurapa zvine mwero uye kushandisa zviwanikwa.
Kushandiswa kwezviwanikwa kunosimbiswa mumiyero yekuburitsa
Panyaya yezviyero zvekuburitsa zvakatemerwa pakurapwa kwetsvina yekumaruwa, mumakore achangopfuura, kurapwa zvine mwero uye kushandiswa kwezviwanikwa kwakasimbiswa zvishoma nezvishoma mumiyero yekuburitsa. Sekureva kwehuwandu, hwaro hwakajairika hwekuitwa kwezviyero zvezvivakwa zvekurapisa ndeye GB18918-2002, asi muna 2019, Ministry of Ecology and Environment yakapa 'Nhungamiro yeKugadzirira kweMvura Kusvibiswa Emission Control Zvinotsanangurwa zveKumaruwa Domestic Wastewater Treatment. Facilities (yeKuitwa Kwekuedza)' (Environmental Affairs Office Soil Letter 〔2019〕 No. 403), iyo inokurudzira kusarudzwa kwakasarudzika kwenitrogen nephosphorus resourcing uye matekinoroji ekushandisa mvura yemuswe. Mushure mezvo, miitiro ichangoburwa yekuburitsa mumatunhu nemaguta zvakare akarerutsa zvinangwa zvavo. Kubatwa zvine mwero kwemvura yetsvina yemumaruwa kuri kusimbiswa uye kusimudzirwa kubva kumusoro kusvika pasi, zvichiisa hwaro hwekushandiswa kunotevera zviwanikwa.

Artificial wetland parizvino ndiyo inonyanya kushandiswa tekinoroji yekuchenesa tsvina yekumaruwa mumaruwa. Iko kushandiswa kunoshanda kwekushandisa zvine hungwaru kwetsvina yemumusha yekumaruwa muChina ichiri kugara padanho remanyoro ekugadzira, dziva rekudzikamisa uye kucheneswa kwevhu. Sezvo kusvibiswa kwepasi pekurima kunosanganisira tsvina yemumaruwa yave iyo inonyanya kukonzera kusvibiswa kwemaruwa muChina, manejimendi ese ebheseni, kudzikisira-pre-blocking-resourcefulness-ecological restoration ichave iyo nzira yekuvandudza yezvekurima pamusoro pekutonga kusvibiswa kwenzvimbo. Saizvozvo, tsvina yemumusha yekumaruwa inoda kushandisa zviwanikwa zvedunhu. Kusimbisa basa rebasa rezvipenyu zvekumaruwa kuburikidza neshanduko yekugadzira, kubatanidza zvidyarwa zvekurasa mvura yekumaruwa, zvinongotarisa kudzikisa zviwanikwa, nekurimazve, kuunza masisitimu ekurapa anoenderana nekugadzirwa kwekurima, uye kupa zvizere basa rekutonga, iyo agro. -ecosystems pachayo inoshanda nenzira inoderedza kusvibiswa chizvarwa uye kubuda.
