Uphando lwezenzululwazi lubonisa ukuba i-nitrogen eninzi engena emanzini iya kubangela i-eutrophication emzimbeni wamanzi kwaye ichaphazele umgangatho wamanzi emzimbeni wamanzi ukuya kwinqanaba elithile. Iimfuno zolawulo lokusingqongileyo lwaseTshayina ziyanda minyaka le, kuba ukukhutshwa kwe-A-level yonyango lwamanzi amdaka kwilizwe lam kunemiqathango engqongqo kumxholo we-N, kwaye iisampulu zamanzi amdaka zasemaphandleni nazo zinemfuno ezithile ze-nitrogen. Namhlanje, i-Liding Environmental Protection iza kwazisa ngokufutshane itekhnoloji yokunciphisa i-nitrification ephuculweyo kuwe.
Itekhnoloji yokunciphisa i-nitrification ephuculweyo ibhekisa ekuphuculeni amandla okubola kweekhompawundi ezine-nitrogen, ukwandisa izinga lokubola kunye nokuphucula umgangatho wokungcola ngokuphatha ulwakhiwo lweentsholongwane, ukongeza izixhobo zomzimba nezekhemikhali kunye nokuphucula inkqubo ngexesha lenkqubo yonyango longcoliseko. Ukunciphisa i-nitrification kwi-nitrification yebhayoloji kunyango lwamanzi amdaka kuye kwatsala ingqalelo yabantu, kodwa indlela yokwenza unyango lwe-nitrification ngempumelelo iseyingxaki enzima kunyango lwamanzi amdaka.
Itekhnoloji yokunciphisa i-nitrification ephuculweyo yi-bio isetyenziswa kakhulu kunyango lwamanzi amdaka asemaphandleni. Ngokongeza iibhaktheriya ezithile, izondlo okanye ii-analogues ze-substrate kunyango lwebhayoloji, i-biomass kunyango inokwandiswa, amandla omzimba okubola kwiingcolisi ezithile anokuphuhliswa, kwaye izinga lokubola linokuphuculwa, ngoko ke kunokufezekisa injongo yonyango lwamanzi amdaka. Le teknoloji ineempawu zexabiso eliphantsi, ukusebenza okuphezulu kunye nongcoliseko oluphantsi. Ukongeza kwizityalo zemveli, ii-microorganisms eziye zathatha inxaxheba ngokucacileyo kumjikelo we-nitrogen kwindalo ziquka iibhaktheriya ze-anammox, ii-aerobic denitrifiers, kunye neebhaktheriya ezisusa i-phosphorus kunye nezinye ii-microorganisms ezibalulekileyo eziguqula i-nitrogen.
Ukuqinisekisa ukuba ukukhutshwa kweekhompawundi ze-nitrogen kwinkqubo yokungcola kufikelela kwinqanaba elimiselweyo, amanyathelo anjengokunyusa izinga lomoya kwisakhiwo, ukwandisa ixesha lokugcina amanzi, ukwandisa umlinganiselo we-sludge reflux, ukunciphisa umthwalo we-sludge, ukulungisa ubushushu bokusabela, okanye ukwandisa ubukhulu be-filler angasetyenziswa kwiprojekthi. Nangona kunjalo, le nkqubo iya kunyusa iindleko zokwakha nokusebenza kweendawo zonyango lwe-sewage, nto leyo ekhokelela kwimpembelelo enkulu kwezoqoqosho. Nangona iteknoloji ye-physicochemical enhanced denitrification yaphuhliswa ngaphambili, kukho iingxaki ezifana neendleko eziphezulu, ukuvelisa iimveliso ezingafunekiyo zokubulala iintsholongwane, kunye nongcoliseko lwesibini. Iinkqubo ezintsha eziqhelekileyo ze-denitrification eziphuculweyo ziquka inkqubo ye-nitrification-denitrification yomgama omfutshane, inkqubo ye-heterooxygenation-aerobic denitrification, i-aerobic granular sludge, inkqubo ye-nitrification-anammox yomgama omfutshane, njl.
Yiyo yonke loo nto kule ngxaki, ukuze ufumane umxholo othe vetshe, nceda uqaphele ukwabelana kukaLiding kwinqaku elilandelayo. I-Liding Environmental Protection ibizimisele kuyilo, uphando kunye nophuhliso, ukwenziwa kunye nokusebenza kwezixhobo zenkqubo yokucocwa kwamanzi amdaka asasazwayo kwicandelo loshishino lokusingqongileyo kangangeminyaka elishumi. Ngokuxhomekeke kwimigca yokuvelisa ezenzekelayo yobungcali kunye neyomgangatho ophezulu, iimveliso zeLiding zinezibonelelo ezicacileyo kumgangatho kunye nokusebenza. Izixhobo zokucocwa kwamanzi amdaka zasekhaya eziziphuhlisileyo zingasetyenziswa kakuhle kwiindawo zasemaphandleni ezisasazekileyo. Ukuba ufuna izisombululo zemveliso kunye neengcebiso zobugcisa, wamkelekile ukubuza. Iwebhusayithi yethu yile: www.lidingep.com whatsapp: +86 19951179575
