Indle yasesibhedlela isho indle ekhiqizwa izibhedlela equkethe amagciwane, izinsimbi ezisindayo, izibulala-magciwane, izinyibilikisi zemvelo, ama-asidi, ama-alkali, kanye ne-radioactivity.Inezici zokungcoliswa kwendawo, izifo eziyingozi, kanye nokutheleleka okucashile.Ngaphandle kokwelashwa okusebenzayo, kungaba yindlela ebalulekile yokusakazeka kwezifo futhi kungcolise kakhulu imvelo.Ngakho-ke, ukwakhiwa kwe ukwelashwa kwendleisitshaloezibhedlela sekube wukhiye wokuxazulula le nkinga.
1.Ukuqoqwa kwendle yasesibhedlela kanye nokwelashwa ngaphambi kwesikhathi
Le phrojekthi yamukela uhlelo lwepayipi lokugeleza kwendle kanye nokugeleza kwamanzi emvula ekhaya, oluhambisana nohlelo lokudonsa amanzi emadolobheni.Indle yezokwelapha kanye nendle yasekhaya endaweni yesibhedlela iqoqwa ngoxhaxha lwamapayipi okukhipha indle, afakwe ngaphambili yimishini yokuhlanza indle esabalele egqitshiwe (ithangi le-septic, isihlukanisi sikawoyela, nethangi le-septic kanye nethangi lokubulala amagciwane elinikezelwe ekuthululeni amawadi amagciwane) endaweni yesibhedlela, bese ekhishelwa esiteshini sokuhlanza indle endaweni yesibhedlela ukuze alashwe.Ngemva kokuhlangabezana nezinga lokukhishwa kwe-Water Polntants Discharge Standard for Medical Institutions, akhishelwa endaweni yokukhuculula indle yasemadolobheni ngoxhaxha lwamapayipi endle.
Incazelo yeyunithi yokucubungula eyinhloko yeukwelashwa kwendleisitshalo
① Umthombo wegridi ufakwe izendlalelo ezimbili zamagridi amaholoholo namacici, anegebe elingu-30 mm phakathi kwamagridi amaholo kanye no-10 mm phakathi kwamagridi amahle.Bamba izinhlayiya ezinkulu zezinto ezimisiwe nezinto ezithambile ezihlanganiswe kahle (ezifana nezinsalela zephepha, amanikiniki, noma izinsalela zokudla) ukuze uvikele iphampu yamanzi namayunithi okucubungula alandelayo.Lapho ubeka, i-graft kufanele itshekiswe nge-engeli engu-60 ° emgqeni ovundlile wesiqondiso sokugeleza kwamanzi ukuze kube lula ukususwa kwezinsalela ezivimbekile.Ukuvimbela ukuchithwa kwamapayipi kanye nokuhlakazeka kwezinto ezivimbekile, umklamo kufanele ulondoloze izinga lokugeleza kwendle ngaphambi nangemuva kokugalela phakathi kuka-0.6 m/s no-1.0 m/s.Izinto ezivinjwe ukugaya kufanele zibulawe amagciwane ngesikhathi sokususwa ngenxa yokuba khona kwenani elikhulu lamagciwane.
② Iphuli yokulawula
Imvelo ye-drainage yasesibhedlela inquma izinga elingalingani lamanzi angenayo avela esiteshini sokuhlanza indle.Ngakho-ke, ithangi elilawulayo lisethelwe ukwenza i-homogenize ikhwalithi kanye nenani lokukhucululwa kwendle kanye nokunciphisa umthelela wemithwalo enomthelela kumayunithi wokuhlanza alandelayo.Ngesikhathi esifanayo, setha ipayipi lokukhipha ingozi echibini lengozi.Imishini yokufaka umoya ifakwe ethangini elilawulayo ukuvimbela ukucwiliswa kwezinhlayiya ezimisiwe futhi kuthuthukiswe ukubola kwe-biodegradability yamanzi angcolile.
③ I-hypoxic aerobic pool
I-Anoxic aerobic tank iyinqubo eyinhloko yokwelashwa kwendle.Inzuzo yayo ukuthi ngaphezu kokungcolisa ukungcola kwezinto eziphilayo, iphinde ibe nomsebenzi othile wokukhipha i-nitrogen ne-phosphorus.Inqubo ye-A/O ixhuma ingxenye engaphambili ye-anaerobic kanye nengxenye ye-aerobic engemuva ochungechungeni, ngesigaba esithi A esingadluli ku-0.2 mg/L kanye nesigaba esithi DO=2 mg/L-4 mg/L.
Esigabeni se-anoxic, amabhaktheriya e-heterotrophic enza i-hydrolyze ukungcola okumisiwe okufana nesitashi, imicu, ama-carbohydrate, nezinto eziphilayo ezincibilikayo endle zibe ama-organic acid, okwenza ukuthi i-macromolecular organic matter ibole ibe yi-molecule encane yezinto eziphilayo.I-insoluble organic matter iguqulwa ibe yi-soluble organic matter.Uma le mikhiqizo ye-anaerobic hydrolysis ingena ethangini le-aerobic ukwelashwa kwe-aerobic, ukubola kwendle kuyathuthukiswa kanye nokusebenza kahle komoyampilo kuyathuthukiswa.
Esigabeni se-anoxic, amagciwane e-heterotrophic ammonifies ukungcola okufana namaprotheni namafutha (N on the organic chain noma amino acid ku-amino acid) ukuze akhulule i-ammonia (NH3, NH4+).Ngaphansi kwezimo ezanele zokuhlinzekwa komoyampilo, i-nitrification ye-autotrophic bacteria i-oxidize i-NH3-N (NH4+) ibe yi-NO3 -, futhi ibuyela echibini A ngokulawula i-reflux.Ngaphansi kwezimo ze-anoxic, i-denitrification yamagciwane e-heterotrophic kunciphisa i-NO3 - ku-nitrogen yamangqamuzana (N2) ukuqedela umjikelezo we-C, N, no-O ku-ecology futhi ibone ukwelashwa kwendle okungenangozi.
④ ithangi lokubulala amagciwane
Ukungcola kwesihlungi kungena ethangini lokuxhumana lokubulala amagciwane ukuze kugcinwe isikhathi esithile sokuxhumana phakathi kwendle nesibulala-magciwane, kuqinisekiswe ukuthi isibulala-magciwane siwabulala ngempumelelo amagciwane emanzini.Amanzi angcolile achithelwa kuxhaxha lwamapayipi kamasipala.Ngokusho kwe "Water Pollutant Discharge Standards for Medical Institutions", isikhathi sokuthinta indle ezibhedlela zezifo ezithathelwanayo akufanele sibe ngaphansi kwamahora angu-1.5, futhi isikhathi sokuthinta indle evela ezibhedlela eziphelele akufanele sibe ngaphansi kwehora le-1.0.
