Uphando lwezenzululwazi lubonisa ukuba i-nitrogen eninzi kakhulu engena emanzini iya kubangela i-eutrophication yomzimba wamanzi kwaye ichaphazele umgangatho wamanzi womzimba wamanzi kwinqanaba elithile. Iimfuno zolawulo lokusingqongileyo yaseTshayina ezisemaphandleni ziyanda minyaka le, ngenxa yokuba ilizwe lam lokukhutshwa kwamanzi amdaka elizwe lam ukukhutshwa komgangatho we-A-level ukukhutshwa okusemgangathweni kunezithintelo ezingqongqo kumxholo we-N, kunye neesampulu zogutyulo lwasemaphandleni nazo zineemfuno ezithile zenitrogen. Namhlanje, uKhuseleko lokusiNgqongileyo lweLiding luza kukwazisa ngokufutshane itekhnoloji eyomeleziweyo yokukhutshwa kwe-denitrification kuwe.
Itekhnoloji ye-denitrification eyandisiweyo ibhekiselele ekuphuculeni isakhono sokuthotywa kweekhompawundi ezinenitrogen, ukwandisa izinga lokuthotywa kunye nokuphucula umgangatho wamanzi amdaka ngokuphatha ubume be-microbial, ukongeza iindlela zomzimba kunye neekhemikhali kunye nokuphucula inkqubo ngexesha lenkqubo yonyango longcoliseko. I-Biological denitrification kunyango lwelindle itsale umdla wabantu, kodwa indlela yokwenziwa ngempumelelo unyango lwe-denitrification iseyingxaki enzima kunyango lwelindle.
Itekhnoloji ye-Bio-enhanced denitrification isetyenziswa kakhulu kucoceko lwasemaphandleni. Ngokongeza iibhaktheriya ezithile, izondlo okanye i-substrate analogs kunyango lwebhayoloji, i-biomass kunyango inokunyuswa, ukuthotywa kwesakhono somzimba kwizinto ezingcolisa izinto ezithile zinokuphuhliswa, kwaye izinga lokuthotywa lingaphuculwa, ngoko kunokufikelela injongo yogutyulo. unyango. Ubuchwephesha buneempawu zexabiso eliphantsi, ukusebenza okuphezulu kunye nongcoliseko oluphantsi. Ukongeza kwiintyatyambo zendabuko, ii-microorganisms eziye zathatha inxaxheba ngokucacileyo kumjikelo we-nitrogen kwindalo nazo zibandakanya iibhaktheriya ze-anammox, i-aerobic denitrifiers, kunye ne-denitrifying i-phosphorus-esusa iibhaktheriya kunye nezinye i-nitrogen-metabolizing microorganisms ezibalulekileyo.
Ukuze kuqinisekiswe ukuba ukukhutshwa kwe-nitrogenous compounds kwinkqubo yogutyulo ifikelela kumgangatho, amanyathelo afana nokunyusa izinga le-aeration yesakhiwo, ukwandisa ixesha lokugcinwa kwe-hydraulic, ukwandisa umlinganiselo we-sludge reflux, ukunciphisa umthwalo we-sludge, ukulungelelanisa ubushushu bokusabela. , okanye ukwandisa ubukhulu befayili ingasetyenziswa kwiprojekthi. Nangona kunjalo, le nkqubo iya kwandisa iindleko zokwakha kunye nokusebenza kwezibonelelo zokucocwa kwamanzi amdaka, okukhokelela kwimpembelelo enkulu yezoqoqosho. Nangona indlela yefizikokhemikhali eyandisiweyo itekhnoloji yokwenziwa kwe-denitrification yaphuhliswa ngaphambili, kukho iingxaki ezinje ngeendleko eziphezulu, kulula ukuvelisa iimveliso zokubulala iintsholongwane, kunye nongcoliseko lwesibini. Iinkqubo ze-denitrification ezitsha eziqhelekileyo eziphuculweyo ziquka inkqubo ye-nitrification-denitrification yexesha elifutshane, inkqubo ye-heterooxygenation-aerobic denitrification, i-aerobic granular sludge, inkqubo ye-nitrification-anammox emfutshane, njl.
Kuko konke oku kulo mbandela, kumxholo othe kratya, nceda uqaphele ukwabelana kukaLiding kuhlelo olulandelayo. Ukhuseleko lokusiNgqongileyo okuLiding luzibophelele kuyilo, uphando kunye nophuhliso, ukwenziwa kunye nokusebenza kwezixhobo zenkqubo yogutyulo logutyulo kwindawo yoshishino lokusingqongileyo iminyaka elishumi. Ukuxhomekeka kwimigca yokuvelisa esemgangathweni kunye nemodyuli ezenzekelayo, iimveliso ze-Liding zineenzuzo ezicacileyo kumgangatho kunye nokusebenza. Izixhobo eziziphuhlisileyo zokucoca ilindle eziziphuhlileyo zekhaya zingasetyenziswa kakuhle kwiindawo ezigqagqeneyo zasemaphandleni. Ukuba ufuna izisombululo zemveliso kunye neengcebiso zobugcisa, wamkelekile ukuba ubuze. Iwebhusayithi yethu yile: www.lidingep.com whatsapp: +86 19951179575
