Ongororo yesainzi inoratidza kuti nitrogen yakawandisa inopinda mumvura inokonzera eutrophication yemvura uye inokanganisa kunaka kwemvura yemvura kusvika pamwero wakati. Zvinodiwa zvekutonga nharaunda kumaruwa muChina zviri kuwedzera gore rega rega, nekuti kubuda kwemvura yetsvina munyika yangu A-level standard discharge ine zvirambidzo zvakasimba pahuwandu hweN, uye sampuro dzetsvina dzekumaruwa dzinewo zvinodiwa zvenitrogen. Nhasi, Liding Environmental Protection ichakupai muchidimbu tekinoroji yekuchenesa mvura.
Tekinoroji yekuchenesa mvura inonaya inoreva kuvandudza kugona kwemakemikari ane nitrogen kuora, kuwedzera mwero wekuora uye kuvandudza mhando yetsvina nekurapa chimiro chehutachiona, kuwedzera nzira dzemuviri nedzemakemikari uye kuvandudza maitiro panguva yekurapa kusvibiswa. Kuchenesa mvura inonaya nemuviri mukurapa tsvina kwakakwezva vanhu, asi maitiro ekuita zvinobudirira kurapwa kwekuchenesa mvura inonaya achiri dambudziko rakaoma mukurapa tsvina.
Tekinoroji yekubvisa manyowa kubva muzvinhu zvipenyu inoshandiswa zvakanyanya mukurapa tsvina yemumaruwa. Nekuwedzera mabhakitiriya chaiwo, zvinovaka muviri kana zvimwe zvinhu zvakafanana mukurapa kwezvipenyu, huwandu hwezvinhu zvipenyu mukurapa hunogona kuwedzerwa, kugona kwemuviri kuora kwezvinosvibisa kunogona kuvandudzwa, uye mwero wekuora kwemvura unogona kuvandudzwa, saka zvinogona kuzadzisa chinangwa chekurapa tsvina. Tekinoroji iyi ine hunhu hwemutengo wakaderera, kushanda kwepamusoro uye kusvibiswa kwakaderera. Kuwedzera kune maruva echinyakare, tupukanana twakatora chikamu mu nitrogen cycle muzvisikwa zvinosanganisirawo mabhakitiriya e-ammox, aerobic denitrifiers, uye denitrifying phosphorus-removing bacteria nezvimwe tupukanana tunokosha tunogadzirisa nitrogen.
Kuti pave nechokwadi chekuti kuburitswa kwemakemikari ane nitrogen mutsvina yetsvina kwasvika padanho rakajairika, zviyero zvakaita sekuwedzera mwero wekufema kwechivako, kuwedzera nguva yekuchengetedza hydraulic, kuwedzera chiyero chesludge reflux, kuderedza mutoro wesludge, kugadzirisa tembiricha ye reaction, kana kuwedzera ukobvu hwefiller zvinogona kushandiswa muchirongwa ichi. Zvisinei, maitiro aya achawedzera mari yekuvaka nekushandisa nzvimbo dzekuchenesa sewage, zvichikonzera kukanganisa kukuru kwehupfumi. Kunyangwe tekinoroji ye physicochemical yakasimbiswa denitrification yakagadzirwa kare, kune matambudziko akadai semutengo wakakwira, nyore kugadzira disinfection by-products, uye kusvibiswa kwechipiri. Maitiro matsva e enhanced denitrification anosanganisira maitiro e short-range nitrification-denitrification, maitiro e heterooxygenation-aerobic denitrification, aerobic granular sludge, maitiro e short-range nitrification-anammox, nezvimwewo.
Ndizvo zvese zviri muchinyorwa chino, kuti muwane zvimwe zvirimo, ndapota teererai kugovaniswa kwaLiding muchinyorwa chinotevera. Liding Environmental Protection yave ichizvipira kugadzira, kutsvaga nekugadzira, kugadzira nekushandisa michina yekurapa tsvina munzvimbo yeindasitiri yezvakatipoteredza kwemakore gumi. Zvichienderana nemitsetse yekugadzira yakagadzirwa nehunyanzvi uye yemhando yepamusoro, zvigadzirwa zveLiding zvine zvakanakira pachena mumhando uye mashandiro. Midziyo yekurapa tsvina yemumba yakagadzirwa yega inogona kushandiswa zvakanaka kunzvimbo dzekumaruwa dzakapararira. Kana uchida mhinduro dzezvigadzirwa nemazano ehunyanzvi, gamuchirai kubvunza.
