Nyaya Yekushandisa Chigadzirwa Chekurapa Tsvina muBeijing

Imwe nzvimbo yekuchenesa tsvina muBeijing ndeimwe yezvivakwa zvakavakwa kugadzirisa matambudziko ekuchenesa tsvina muguta nenzvimbo dzakapoteredza. Yakapedzwa zviri pamutemo uye yakashandiswa muna Chikumi 2009. Parizvino, nzvimbo iri pakati peguta iri inoshandisa sisitimu yekubvisa tsvina isina nzvimbo dzekuchenesa tsvina. Tsvina haichengetwi uye haidururwi murwizi kuburikidza nepombi iripo, zvichikonzera kusvibiswa kukuru kumamiriro emvura aripo. Nekuwedzera kukurumidzira kwekuvakwa kwemaguta, huwandu hwevanhu muguta huri kukura nekukurumidza, uye huwandu hwetsvina huri kuwedzera zuva nezuva. Pamusoro pezvo, kuchengetedza matsime emvura muguta, sechikamu chakakosha chezvivakwa zvemaguta, zvakakosha kuvaka nzvimbo yekuchenesa tsvina muguta rino. Nzvimbo itsva yekuchenesa tsvina ichavakwa yakatenderedza nzvimbo yekuchenesa tsvina, uye mvura yakacheneswa ichashandiswa senzvimbo yekuchenesa tsvina kana kudira murwizi rwakati. Chiyero chepurojekiti i20000 m3/d munguva pfupi iri kutevera uye 30000 m3/d munguva refu.

Chivako chikuru chekuvaka chinosanganisira: imba yepombi inopinza (inosanganisira imba yegrille), imba yegrit yemhepo ine dutu, imba yekuwachisa jecha, mugero we oxidation ditch, tangi re sedimentation, imba yepombi ye sludge, imba yemuchina wekubvisa mvura ine sludge netangi rekuchengetera matope, mashedhi ekuchengetera sludge, nzira dzekuuraya utachiona hweUV, nzvimbo dzekubvisa kunhuhwirira, uye makamuri ekuyeresa; zvimwe zvivakwa nezvivakwa zvinosanganisira imba huru ye substation, chivako chakazara, dziva remoto nekamuri repombi, imba ye heat pombi, warehouse, imba yekuchengetedza, nekamuri rekutaurirana. Chivako chakazara chine imba yekudzora yepakati nerabhoritari, iyo inogona kutarisa nekudzora data rakasiyana-siyana. Kuitira kuti vashandi vari panzvimbo yacho vagone kugadzirisa ma process parameters nenguva. Nzvimbo yedu inoshandisa nzira ye oxidation ditch activated sludge yekurapa tsvina yemuviri, tichifunga nezvezvinodiwa zvekubvisa phosphorus ne nitrogen.

Shanghai BOQU Instrument inopa musanganiswa wekutarisa otomatiki uye kutarisa nemaoko pachirongwa ichi, Kutarisa otomatiki kunogadzirisa matambudziko ekambani ekuzvishandira uye ekugadzirisa fekitari yekuchenesa tsvina uye kunovimbisa kugadzikana uye kuvimbika kwemhando yemvura panguva yekuchenesa kwekambani. Beijing Urban Drainage Monitoring Station yakapihwa basa rekutarisa nemaoko. Kuburikidza nebasa rakazara rekutarisa uye kudzora mhando yemvura kuti ive nechokwadi chekuti mhando yemvura yakagadzikana uye yakavimbika.
