Ukungeni kwendle ezibhedlela kubhekisele ekukhundleweni kwendle okwenziwe izibhedlela eziqukethe ama-pathogen, izinsimbi ezisindayo, ama-disinfectants, ama-arkalil solvents, ama-acid, ama-alkali kanye nomsakazo. Inezimpawu zokungcoliswa kwendawo, ukutheleleka okunamandla, kanye nokutheleleka kwe-latent. Ngaphandle kokwelashwa okusebenzayo, kungaba indlela ebalulekile yokusakazeka kwezifo futhi ingcolise imvelo. Ngakho-ke, ukwakhiwa kwe ukwelashwa kwendletshalaEzibhedlela sekuyisihluthulelo sokuxazulula le nkinga.
1.Ukuqoqwa kwendle ezibhedlela kanye nokuhlekisa
Iphrojekthi yemukela indle yasendlini yokukhucululwa kwendle ezifuywayo kanye nohlelo lwe-rainwater flow Pipeline, oluhambisana nohlelo lokudonsa amanzi e-Urban. Ukukhucululwa kwendle yezokwelapha kanye nokukhucululwa kwendle kwasekhaya endaweni yesibhedlela kuqoqwa nge-drainage Pipe Network, kuthathwe amadivaysi okusabalalisa okusabalalisa wendle (i-septic tank kanye ne-septic Tank enikezelwe esiteshini sokwelashwa esibhedlela, bese ikhishwe esiteshini sokwelashwa sendle endaweni yesibhedlela ukuthola ukwelashwa. Ukwelashwa. Ngemuva kokuhlangana nenqubo yokuphuma kwamanzi okungcoliswa kwamanzi ezikhungweni zezokwelapha, zikhishwa esiteshini sokwelashwa kwendle emadolobheni nge-Urban Seage Pipe Network.
Ukuchazwa kweyunithi enkulu yeukwelashwa kwendletshala
① Igridi kahle ifakwe izingqimba ezimbili zama-grid ama-coarse and amahle, ngegebe lama-30 mm phakathi kwamagridi ahlanganayo kanye ne-10 mm phakathi kwama-grid amahle. Hlukanisa izinhlayiya ezinkulu zendaba emiswe okwesikhashana kanye nendaba ethambile ethambile (enjengezikhala zamaphepha, ama-rafs, noma izinsalela zokudla) ukuvikela ama-pump wamanzi namayunithi alandelayo wokucubungula. Lapho ubeka, i-grating kufanele ifakwe emanzini angu-60 ° kuya emugqeni ovundlile wendlela yokugeleza kwamanzi ukwenza lula ukususwa kwezinsalela ezivinjelwe. Ukuvimbela ukufakwa kwepayipi kanye nokuhlakazwa kwezinto ezivinjelwe, umklamo kufanele alondoloze izinga lokugeleza kwendle ngaphambi nangemva kokuthonya phakathi kuka-0.6 m / s. Izinto ezivinjelwe yi-grating kufanele zibulawe amagciwane ngesikhathi sokususwa ngenxa yokuba khona kwenani elikhulu lamagciwane.
② Ukulawula ichibi
Unemvelo yokudonsa esibhedlela inquma ikhwalithi engalingani kwamanzi angenayo esiteshini sokwelashwa kwendle. Ngakho-ke, ithangi elawula lisethelwe ukuze lizenzele ikhwalithi nenani lokuhambisa indle futhi linciphise umthelela wemithamo yomthelela kumayunithi ezokulashwa alandelayo. Ngasikhathi sinye, setha ipayipi elenza ngengozi echibini lengozi. Kufakwe imishini yokulawula ethangini elilawulayo ukuvikela ukunqunyelwa kwezinhlayiya ezimisiwe futhi kuthuthukise i-biodewadeability yamanzi amdaka.
③ I-Hypoxic Aerobic Poolic
Ithangi le-anoxic aerobic inqubo ebalulekile yokwelashwa kwendle. Inzuzo yayo ukuthi ngaphezu kokungcoliswa kwemvelo okulimazayo, futhi inomsebenzi othile wokususwa kwe-nitrogen kanye ne-phosphorus. Inqubo ye-A / O ixhumanisa isigaba sangaphambili se-Anaerobic kanye nesigaba se-Aerobic esisemuva, nesigaba asidluli ku-0.2 mg / l kanye ne-o Isigaba senza = 2 mg / 4 mg / l.
Esigabeni se-anoxic, ama-hetorotrofIc bacteria hydrolze amise ukungcola okunjenge-starch, imicu, ama-carbohydrate, futhi ancibilike izinto ezingethembisa ukuhambisa indle kuma-organic acid, okubangela ukuba kube nezinto eziphilayo ze-molecule. Izinto eziphilayo ze-insoluble ziguqulwa zibe yinto ethokomele ye-organic. Lapho le mikhiqizo ye-anaerobic hydrolysis ingena ithangi le-aerobic ngenxa yokwelashwa kwe-aerobic, i-biodegradeabilibility yokuthuthwa kwendle ithuthukisiwe futhi ukusebenza kahle komoya-mpilo kuthuthukiswa.
Esigabeni se-anoxic, amagciwane e-heterotrophic a ammonia amoni amaprotheni namafutha (n ku-organic chain noma i-amino acid e-amino acid) ukuze i-ammonia (NH3, NH4 +). Ngaphansi kwemibandela ezanele yomoya-mpilo, i-nitrization yama-bacterium autotrophic oxidizes NH3-N (NH4 +) ku-NO3 -, futhi ibuyela echibini i-Reflux control. Ngaphansi kwezimo ze-anoxic, ukuhlukaniswa kwamagciwane we-heterotrophic kunciphisa uNo3 - ku-molecular nitrogen (N2) ukuqedela umjikelezo we-c, n, no-o ngokucolwa ngemvelo futhi uqaphele ukwelashwa ngendle.
④ Tank Tank
I-Whindluent yokuhlunga ingena ithangi lokuxhumana lokubulala amagciwane ukuze lilondoloze isikhathi esithile sokuxhumana phakathi kokukhucululwa kwendle kanye nokubulala amagciwane, ukuqinisekisa ukuthi ukubulala amagciwane kubulala ngempumelelo amagciwane emanzini. I-Effaent ikhishwa kwinethiwekhi yePipeline kaMasipala. Ngokusho "ukukhishwa kwamanzi okungcolisa amanzi ezikhungweni zezokwelapha", isikhathi sokuxhumana sendle esibhedlela esithathelwandle izibhedlela ezithathelwathayo akufanele sibe ngaphansi kwamahora ayi-1.5, futhi nesikhathi sokuthengwa sendle ezisuselwa ezibhedlela eziphelele akufanele zibe ngaphansi kwehora le-1,0.
