Inqubo yokuhlanza indle ihlukaniswe izigaba ezintathu:
Ukwelashwa okuyinhloko: ukwelashwa ngokomzimba, ngokwelashwa kwemishini, okufana ne-grille, i-sedimentation noma i-air flotation, ukususa amatshe, isihlabathi namatshe, amafutha, amafutha, njll.
Ukwelashwa kwesibili: ukwelashwa kwamakhemikhali ezinto eziphilayo, ukungcola emanzini kuchithwa futhi kuguqulwe kube udaka ngaphansi kwesenzo sama-microorganisms.
Ukwelashwa okusezingeni eliphezulu: ukwelashwa okuthuthukisiwe kokuthuthwa kwendle, okuhlanganisa ukususwa kwemisoco kanye nokubulala amagciwane endle nge-chlorination, imisebe ye-ultraviolet noma ubuchwepheshe be-ozone. Ngokuya ngezinhloso zokwelashwa kanye nekhwalithi yamanzi, ezinye izinqubo zokuhlanza indle azifaki zonke lezi zinqubo ezingenhla.
01 Ukwelashwa okuyisisekelo
Isigaba sokwelapha esisebenza ngomshini (izinga lokuqala) sihlanganisa izakhiwo ezifana nama-grille, ama-grit chamber, amathangi ayisisekelo e-sedimentation, njll., ukususa izinhlayiya ezimahhadla kanye nezinto eziqinile ezimisiwe. Umgomo wokwelapha ukuzuza ukuhlukaniswa okuqinile-oketshezi ngokusebenzisa izindlela ezingokwenyama nokuhlukanisa ukungcola nendle , okuyindlela evame ukusetshenziswa yokuhlanza indle.
Ukwelashwa ngemishini (okuyinhloko) kuyiphrojekthi edingekayo yazo zonke izinqubo zokuhlanza indle (yize ezinye izinqubo ngezinye izikhathi zishiya ithangi lokuqala lokuthungatha), futhi amazinga ajwayelekile okususwa kwe-BOD5 kanye ne-SS ekwelashweni okuyinhloko kokuthuthwa kwendle ama-25% no-50%, ngokulandelana. .
Ezitshalweni zokuhlanza indle ye-phosphorus ne-nitrogen, ama-aerated grit chamber ngokuvamile awanconywa ukugwema ukususwa kwezinto eziphilayo ezonakaliswe ngokushesha; lapho izici zekhwalithi zamanzi zendle eluhlaza zingakuvumeli ukususwa kwe-phosphorus ne-nitrogen, ukusethwa kwe-sedimentation eyinhloko kanye nokusetha Indlela kufanele ihlaziywe ngokucophelela futhi ibhekwe ngokulandela inqubo yokulandelela izici zekhwalithi yamanzi, ukuze kuqinisekiswe ukuthi kanye nokwenza ngcono izinga lamanzi elinethonya lezinqubo zokulandelela ezifana nokususwa kwe-phosphorus kanye nokukhishwa kwe-denitrification.
02 Ukwelashwa kwesibili
Ukwelashwa ngamakhemikhali endle kungokwesibili, ngenjongo eyinhloko yokukhipha izinto eziqinile ezilengayo ezingacwiki kanye nezinto eziphilayo ezincibilikayo. Ukubunjwa kwayo kwenqubo kuhlukahlukene, okungahlukaniswa ngendlela ye-sludge ecushiwe, indlela ye-AB, indlela ye-A/O, Indlela ye-A2/O, indlela ye-SBR, indlela yokukhipha i-oxidation, indlela yechibi lokuzinzisa, indlela ye-CASS, indlela yokwelapha umhlaba kanye nezinye izindlela zokwelashwa. Njengamanje, izindawo eziningi zokuhlanza indle emadolobheni zisebenzisa indlela yodaka ecushiwe.
Umgomo wokwelashwa kwebhayoloji ukuqedela ukubola kwento ephilayo kanye nokuhlanganiswa kwezinto eziphilayo ngesenzo sebhayoloji, ikakhulukazi isenzo samagciwane, nokuguqula ukungcola kwemvelo kube imikhiqizo yegesi engenabungozi (CO2), imikhiqizo engamanzi (amanzi) kanye nemikhiqizo enothile nge-organic. . Umkhiqizo oqinile (iqembu le-microbial noma i-biological sludge); udaka oluningi lwebhayoloji luhlukaniswa kokuqinile noketshezi ethangini lokuthungatha bese lukhishwa endle ehlanziwe. i
03 Ukwelashwa kwemfundo ephakeme
Ukwelashwa okuphakeme ukuhlanzwa kwamanzi okuseqophelweni eliphezulu, okuyinqubo yokuhlanza amanzi angcolile ngemva kokwelashwa kwesibili, futhi kuyindlela ephakeme kakhulu yokuhlanza indle. Njengamanje, azikho izimboni eziningi zokuhlanza indle ezweni lakithi ezisetshenziswa ngendlela engokoqobo.
Iwaphika futhi yenze amanzi angabi naphosphorize ngemva kokwelashwa kwesibili, isuse ukungcola okusele emanzini nge-activated carbon adsorption noma i-reverse osmosis, futhi ikhiphe amagciwane nge-ozone noma i-chlorine ukuze ibulale amagciwane namagciwane, bese ithumela amanzi alashiwe e-Waterways asetshenziswa njenge imithombo yamanzi okugeza izindlu zangasese, ukufutha imigwaqo, ukuchelela amabhande aluhlaza, amanzi ezimboni, nokuvimbela umlilo.
Kungabonakala ukuthi indima yenqubo yokuhlanza indle yenziwa kuphela ngokuguqulwa kwe-biodegradation kanye nokuhlukaniswa koketshezi oluqinile, ngenkathi ihlanza indle futhi inothisa ukungcola odongeni, kuhlanganise ne-sludge eyinhloko ekhiqizwa esigabeni sokuqala sokwelashwa, I-sludge esele ecushiwe. ekhiqizwa esigabeni sokwelapha sesibili kanye nodaka lwamakhemikhali olukhiqizwa ekwelashweni okuphakeme.
Ngenxa yokuthi lezi zidaka ziqukethe inani elikhulu lezinto eziphilayo kanye namagciwane, futhi zonakaliswa kalula futhi zinuka, kulula ukubangela ukungcola kwesibili, futhi umsebenzi wokuqeda ukungcola awukaqedwa. Udaka kufanele lulahlwe ngendlela ethile ngokunciphisa umthamo othile, ukuncishiswa kwevolumu, ukuqiniswa kanye nokwelashwa okungenangozi. Impumelelo yokwelashwa nokulahlwa kodaka kunomthelela obalulekile esitshalweni sokukhucululwa kwendle futhi kumele kuthathwe ngokungathí sina.
Uma udaka lungelashwa, udaka kuyodingeka lukhishwe namanzi angcolile ahlanzekile, futhi umphumela wokuhlanza wesikhungo sokukhuculula indle uzosuswa. Ngakho-ke, ekusetshenzisweni kwangempela kwesicelo, ukwelashwa kodaka ohlelweni lokuhlanza indle nakho kubaluleke kakhulu.
04 Inqubo yokuqeda iphunga
Phakathi kwazo, izindlela ezingokomzimba ikakhulukazi zifaka indlela yokuhlanza, indlela ye-adsorption, njll.; izindlela zamakhemikhali zihlanganisa indlela yokumunca, indlela yokuvutha, njll.; ishawa njll.
Ubudlelwano phakathi kokwelashwa kwamanzi nokuhlolwa kwekhwalithi yamanzi
Ngokuvamile, imishini yokuhlola izinga lamanzi izosetshenziswa ohlelweni lokuhlanza amanzi angcolile, ukuze sazi isimo esithile sekhwalithi yamanzi futhi sibone ukuthi iyahlangabezana yini nezinga!
Ukuhlolwa kwezinga lamanzi kuyadingeka ekwelashweni kwamanzi. Ngokuqondene nesimo samanje, ayanda amanzi asetshenziswa ekuphileni nasezimbonini, futhi amanye amanzi angcolile empilweni kanye nendle ekukhiqizeni izimboni nakho kuyanda. Uma amanzi ekhishwa ngokuqondile ngaphandle kokuphuma, ngeke nje angcolise imvelo, kodwa futhi alimaze kakhulu uhlelo lwemvelo yemvelo. Ngakho-ke, kufanele kube nokuqwashisa ngokukhishwa kwendle nokuhlolwa. Iminyango efanele izicacisile izinkomba ezifanele zokuhlanzwa kwamanzi. Kuphela ngemva kokuhlolwa nokuqinisekisa ukuthi izindinganiso ziyafinyelelwa lapho zingakhishwa khona. Ukutholwa kwendle kuhilela izinkomba eziningi, njenge-pH, okuqinile okumisiwe, i-turbidity, isidingo sekhemikhali komoyampilo(COD), isidingo se-biochemical oxygen(BOD), isamba se-phosphorus, isamba se-nitrogen, njll. Kungemva kokuhlanzwa kwamanzi kuphela lapho lezi zinkomba zingaba ngaphansi kokukhishwa. izinga singaqinisekisa umphumela wokwelashwa kwamanzi, ukufeza inhloso yokuvikelwa kwemvelo.
