Ucwaningo lwesayensi lubonisa ukuthi i-nitrogen eningi kakhulu engena emanzini izodala i-eutrophication yomzimba wamanzi futhi ithinte izinga lamanzi lomzimba wamanzi ngezinga elithile.Izidingo zokulawulwa kwemvelo yasemaphandleni yaseShayina ziyanda minyaka yonke, ngenxa yokuthi ukukhishwa kwendle kwezwe lami kwezinga elingu-A kunemikhawulo eqinile kokuqukethwe kwe-N, futhi amasampula endle asemaphandleni nawo anezidingo ezithile ze-nitrogen.Namuhla, i-Liding Environmental Protection izokwethula kafushane ubuchwepheshe bokukhishwa kwe-denitrification obuthuthukisiwe.
Ubuchwepheshe be-denitrification obuthuthukisiwe bubhekisela ekwenzeni ngcono ikhono lokuwohloka kwezinhlanganisela eziqukethe i-nitrogen, ukukhulisa izinga lokuwohloka kanye nokwenza ngcono ikhwalithi yamanzi angcolile ngokwelapha ukwakheka kwamagciwane, ukwengeza izindlela ezingokomzimba namakhemikhali kanye nokwenza ngcono inqubo phakathi nenqubo yokwelapha ukungcola.Ukukhishwa kwe-Biological denitrification ekuhlanzeni indle kuye kwadonsa ukunaka kwabantu, kodwa ukuthi kwenziwa kanjani ngempumelelo ukwelashwa kwe-denitrification kuseyinkinga enzima ekuhlanzeni indle.
Ubuchwepheshe be-Bio-enhanced denitrification busetshenziswa kakhulu ekuhlanzeni indle ezindaweni zasemakhaya.Ngokungeza amabhaktheriya athile, izakhi noma ama-analogues e-substrate ekwelapheni kwezinto eziphilayo, i-biomass ekwelapheni ingandiswa, ikhono lokuwohloka lomzimba ekungcoleni okuthile lingathuthukiswa, futhi izinga lokuwohloka lingathuthukiswa, ngakho-ke lingafinyelela umgomo wokukhucululwa kwendle. ukwelashwa.Ubuchwepheshe bunezici zezindleko eziphansi, ukusebenza okuphezulu nokungcola okuphansi.Ngaphezu kwezitshalo zendabuko, ama-microorganisms abambe iqhaza ngokucacile emjikelezweni we-nitrogen emvelweni ahlanganisa namagciwane e-anammox, ama-aerobic denitrifiers, kanye ne-denitrifying amagciwane akhipha i-phosphorus kanye namanye amagciwane abalulekile agaya i-nitrogen.
Ukuze kuqinisekiswe ukuthi ukukhululwa kwezinhlanganisela ze-nitrogen ohlelweni lokukhucululwa kwendle kufinyelela ezingeni, izinyathelo ezinjengokwandisa izinga lokungena kwamanzi kwesakhiwo, ukwandisa isikhathi sokugcinwa kwamanzi, ukwandisa isilinganiso se-sludge reflux, ukunciphisa umthwalo we-sludge, ukulungisa izinga lokushisa lokuphendula. , noma ukwandisa ukushuba kwesigcwalisi kungasetshenziswa kuphrojekthi.Kodwa-ke, le nqubo izonyusa izindleko zokwakha nezokusebenza kwezindawo zokukhuculula indle, okuzoba nomthelela omkhulu kwezomnotho.Nakuba indlela ye-physicochemical technology ethuthukisiwe yokukhishwa kwe-denitrification yathuthukiswa ngaphambili, kunezinkinga ezifana nezindleko eziphezulu, ukukhiqiza kalula imikhiqizo ephuma emagciwane, kanye nokungcola kwesibili.Izinqubo ezintsha ezithuthukisiwe zokukhishwa kwe-denitrification zibandakanya inqubo yebanga elifushane le-nitrification-denitrification, inqubo ye-heterooxygenation-aerobic denitrification, i-aerobic granular sludge, inqubo ye-nitrification-anammox yebanga elifushane, njll.
Yilokho kuphela okwalolu daba, ukuze uthole okuqukethwe okwengeziwe, sicela unake ukwabelana kuka-Liding kumagazini olandelayo.I-Liding Environmental Protection izibophezele ekwakhiweni, ocwaningweni nasekuthuthukiseni, ekwakhiweni nasekusebenzeni kwemishini yokuhlanza indle ehlukaniselwe indawo endaweni yemboni yezemvelo iminyaka eyishumi.Ngokuthembela emigqeni yokukhiqiza esezingeni eliphakeme nemodular, imikhiqizo ye-Liding inezinzuzo ezisobala ngekhwalithi nokusebenza.Imishini yokuhlanza indle yasekhaya esezakhiwe yona ingasetshenziswa kahle ezindaweni zasemakhaya ezihlakazekile.Uma udinga izixazululo zomkhiqizo nezeluleko zobuchwepheshe, wamukelekile ukubuza.Iwebhusayithi yethu ithi: www.lidingep.com whatsapp: +86 19951179575
