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. Zvimwe zvivakwa zvekurapa zvinomera zvesuweji yemuguta "miniaturisation", kuvaka, kushanda uye kugadzirisa mutengo wakakwira, nzvimbo dzekumaruwa dzakaoma kubvuma, asi zvakare dzakaregeredza kushandiswa kwetsvina yemumba kuchengetedza basa rekubereka kwevhu. 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 zvekubuda kwetsvina yekumaruwa, mumakore achangopfuura, kurapwa kuri pakati nepakati uye kushandiswa kwezviwanikwa kwakasimbiswa zvishoma nezvishoma mumiyero yekuburitsa. Zvinoenderana nehuwandu hwe data, hwaro hwakajairika hwekuitwa kwezviyero zvezvivakwa zvekurapisa ndeye GB18918-2002, asi muna 2019, Ministry of Ecology uye Yezvakatipoteredza yakapa "Nhungamiro yeGadziriro yeMvura Kusvibiswa Emission Control Matsananguriro eRural Domestic Wastewater Treatment. Facilities (yeKuedza Kuitwa)” (Environmental Affairs Office Soil Letter 〔2019〕 No. 403), iyo inokurudzira kusarudzwa kwakasarudzika kwenitrogen uye phosphorus resourcing uye tailwater utilization tekinoroji. Mushure mezvo, miitiro ichangoburwa yekuburitsa mumatunhu nemaguta zvakare akarerutsa zvinangwa zvavo. Kubatwa zvine mwero kwetsvina yemumaruwa kuri kusimbiswa nekusimudzirwa kubva kumusoro kusvika pasi, zvichiisa hwaro hwekushandiswa kwezviwanikwa.
Development Direction of Regionalised Sewage Resource Utilization
Artificial wetland parizvino ndiyo inonyanya kushandiswa tekinoroji yekuchenesa tsvina yekumaruwa mumaruwa. Iko kushandiswa kunoshanda kwekushandisa zvine hungwaru kwetsvina yekumaruwa yemumusha muChina kuchiri 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 zvekumaruwa zvekurasa tsvina, izvo zvinongobva mukuderedza zviwanikwa, nekurimazve, kuunza masisitimu ekurapa anoenderana nekugadzirwa kwekurima, uye kupa zvizere kuita basa rekutonga, agro-ecosystems pachawo anoshanda nenzira yekuti anogona kuderedza chizvarwa chinosvibisa uye kubuda.
Izvo zviri pamusoro ndizvo zvese zvenyaya iyi, zvimwe zvemukati ndapota teerera kune LiDing kuchengetedza kwezvakatipoteredza inotevera nyaya yekugovera. Li Ding akazvipira mukutsvagisa nekusimudzira, kuvaka uye kushanda kwemidziyo yetsvina yekumaruwa yakasanganiswa kwemakore gumi. Kuburikidza nekuenderera mberi kwehunyanzvi hwekuvandudza tekinoroji, tinoyedza kuita mupiro une mwero mukuvandudza nharaunda yevanhu. Li Ding kuchengetedzwa kwezvakatipoteredza mhuri mhando sewage treatment equipment scavenger inogona kunyatso shandiswa kune ruzhinji rwenzvimbo dzekumaruwa.
