Yekushandisa Nyaya yeSewage Treatment Plant muBeijing

Imwe nzvimbo yekuchenesa tsvina muBeijing ndeimwe yezvivakwa zvakavakwa kugadzirisa matambudziko ekuchenesa tsvina muguta nenzvimbo dzaro dzakatenderedza. Yakapedzwa zviri pamutemo ikatanga kushandiswa muna Chikumi 2009. Parizvino, nzvimbo yepakati pedhorobha inotora nzira yakabatana yekugezesa mvura isina nzvimbo dzekuchenesa tsvina. Tsvina yacho haicheneswe uye inorasirwa murwizi kuburikidza nepombi yakabatanidzwa iripo, zvichikonzera kusvibiswa kukuru kumamiriro emvura aripo. Nekuwedzera kwekuwedzera kwekuvakwa kwemadhorobha, huwandu hweguta huri kukura nekukurumidza, uye huwandu hwetsvina huri kuwedzera zuva nezuva. Pamusoro pezvo, kuitira kuchengetedza matsime emvura eguta, sechikamu chakakosha chezvivakwa zvemudhorobha, zvinodikanwa kuvaka nzvimbo yekuchenesa tsvina muguta rino. Ivhu idzva remanyoro richavakwa rakatenderedza pombi yetsvina, uye mvura yakacheneswa ichashandiswa semanyuko evhu rekugadzira kana kuti kudirwa mune rumwe rwizi. Chiyero chepurojekiti i20000 m3/d munguva pfupi iri kutevera uye 30000 m3/d munguva refu.

(ndege mufananidzo wekuchenesa tsvina muBeijing)

Chivakwa chikuru chekuvaka chinosanganisira: inlet pombi yekamuri (inosanganisira grille kamuri), cyclone grit kamuri, jecha rekugezera kamuri, pamusoro pekuvhenekesa oxidation ditch, sedimentation tank, sludge pombi imba, sludge dewatering muchina uye dhaka rekuchengetera tangi, sludge Storage shed, UV disinfection nzira uye makamuri, kunhuhwirira, uye kuita zvivakwa. zvimwe zvivakwa uye zvimiro zvinosanganisira main substation room, comprehensive building, fire pool and pombi room, heat pump room, warehouse, repair room, and communication room. Chivako chakakwana chakashongedzerwa nekamuri yepakati yekudzora uye murabhoritari, iyo inogona kunyatso tarisa uye kudzora akasiyana data. Kuitira kuti vashandi vepa-saiti vagone kugadzirisa ma paramita ekuita panguva yakakodzera. Nzvimbo yedu inoshandisa oxidation ditch activated sludge nzira yechipiri biological kurapwa kwetsvina, tichifunga zvinodiwa zvekubvisa phosphorus uye nitrogen.

Ukuimba zvigadzirwa:

Shanghai BOQU Instrument inopa musanganiswa wekutarisa otomatiki uye kutariswa kwemanyorero epurojekiti iyi, Otomatiki yekutarisa inogadzirisa iyo kambani kuzvishanda uye kugadzirisa matambudziko epombi yekuchenesa tsvina uye inovimbisa kugadzikana uye kuvimbika kwemhando yemvura panguva yekurapa kwekambani. Manual yekutarisa yakapihwa Beijing Urban Drainage Monitoring Station inoita yekutarisa. Kuburikidza nehupamhi hwemvura yekutarisa uye kutonga basa kuti ive nechokwadi chakagadzikana uye chakavimbika kunaka kwemvura.
