Ucwaningo lwesayensi lubonisa ukuthi i-nitrogen eningi kakhulu engena emanzini izobangela ukuntuleka kwamanzi emzimbeni wamanzi futhi ithinte ikhwalithi yamanzi emzimbeni wamanzi ngezinga elithile. Izidingo zokuphathwa kwemvelo yasemakhaya eShayina ziyanda minyaka yonke, ngoba ukukhishwa kwendle okujwayelekile kwezwe lami kwe-A-level kunemikhawulo eqinile kokuqukethwe kwe-N, futhi amasampula endle asemakhaya nawo anezidingo ezithile ze-nitrogen. Namuhla, i-Liding Environmental Protection izokwethula kafushane ubuchwepheshe obuthuthukisiwe bokuhlanzwa kwamanzi.
Ubuchwepheshe bokuhlanzwa kwamanzi ahlanzekile bubhekisela ekuthuthukiseni ikhono lokuhlanzwa kwamakhemikhali aqukethe i-nitrogen, ukwandisa izinga lokuhlanzwa kwamanzi ahlanzekile kanye nokuthuthukisa ikhwalithi yokungcola ngokwelapha isakhiwo samagciwane, ukwengeza izindlela zomzimba nezamakhemikhali kanye nokuthuthukisa inqubo ngesikhathi senqubo yokwelapha ukungcola. Uhlanzwa kwamanzi ahlanzekile ahlanzekile ahlanzekile ekwelashweni kwamanzi ahlanzekile kuye kwaheha ukunaka kwabantu, kodwa indlela yokwenza ngempumelelo ukwelashwa kohlanzwa kwamanzi ahlanzekile kuseyinkinga enzima ekwelashweni kwamanzi ahlanzekile.
Ubuchwepheshe bokususa i-nitrification obuthuthukisiwe nge-bio busetshenziswa kabanzi ekwelapheni indle yasemakhaya. Ngokufaka amabhaktheriya athile, izakhamzimba noma ama-analog e-substrate ekwelapheni kwezinto eziphilayo, i-biomass ekwelapheni ingandiswa, ikhono lokonakala komzimba ezintweni ezithile ezingcolisayo lingathuthukiswa, futhi izinga lokuwohloka lingathuthukiswa, ngakho-ke kungafezwa umgomo wokwelashwa kwendle. Ubuchwepheshe bunezici zezindleko eziphansi, ukusebenza okuphezulu kanye nokungcola okuphansi. Ngaphezu kwezitshalo zendabuko, ama-microorganisms abambe iqhaza ngokusobala emjikelezweni we-nitrogen emvelweni nawo afaka amabhaktheriya e-anammox, ama-aerobic denitrifiers, kanye nama-denitrifying phosphorus-removing bacteria kanye namanye ama-microorganisms abalulekile aguqula i-nitrogen.
Ukuze kuqinisekiswe ukuthi ukukhishwa kwamakhemikhali ane-nitrogen ohlelweni lokukhuculula indle kufinyelela izinga elijwayelekile, izinyathelo ezinjengokwandisa izinga lokungenisa umoya kwesakhiwo, ukwandisa isikhathi sokugcina amanzi, ukwandisa isilinganiso se-sludge reflux, ukunciphisa umthwalo we-sludge, ukulungisa izinga lokushisa lokusabela, noma ukwandisa ukujiya kwesigcwalisi kungasetshenziswa kuphrojekthi. Kodwa-ke, le nqubo izokwandisa izindleko zokwakha nokusebenza kwezindawo zokuhlanza indle, okuholela emthonjeni omkhulu wezomnotho. Nakuba ubuchwepheshe bokukhuculula indle obuthuthukisiwe ngendlela ye-physicochemical bathuthukiswa ngaphambilini, kunezinkinga ezifana nezindleko eziphakeme, imikhiqizo engenziwa kalula yokubulala amagciwane, kanye nokungcola kwesibili. Izinqubo ezintsha ezivamile zokukhipha indle zihlanganisa inqubo ye-nitrification-denitrification yebanga elifushane, inqubo ye-heterooxygenation-aerobic denitrification, i-aerobic granular sludge, inqubo ye-nitrification-anammox yebanga elifushane, njll.
Yilokho kuphela kule nkinga, ukuze uthole okunye okuqukethwe, sicela unake ukwabelana kukaLiding kumagazini olandelayo. I-Liding Environmental Protection ibilokhu izibophezele ekwakhiweni, ocwaningweni nasekuthuthukisweni, ekukhiqizweni nasekusetshenzisweni kwemishini yohlelo lokwelapha indle ehlukaniswe endaweni yemboni yezemvelo iminyaka eyishumi. Ithembele emigqeni yokukhiqiza ezenzakalelayo esezingeni eliphezulu nelijwayelekile, imikhiqizo ye-Liding inezinzuzo ezisobala ngekhwalithi nokusebenza. Imishini yokwelapha indle yasekhaya ezithuthukisile ingasetshenziswa kahle ezindaweni zasemakhaya ezihlakazekile. Uma udinga izixazululo zomkhiqizo nezeluleko zobuchwepheshe, wamukelekile ukubuza.
