Njengelibhizinisi lekulawula kungcola, umsebenti lomcoka kakhulu wesikhungo sekuhlanta imfucuza kucinisekisa kutsi imfucuza lephumako ihlangabetana nemazinga. Kepha, ngekutsi emazinga ekukhipha emanti lacinile aya ngekuya kanye nekuba nelulaka lwebahloli bekuvikela imvelo, kuletse kucindzeteleka lokukhulu kwekusebenta esikhungwini sekuhlanta imfucuza. Kuya ngekuba matima mbamba kukhipha emanti.
Ngekubuka kwembhali, imbangela lecondzile yebumatima bekufinyelela esigabeni sekukhishwa kwemanti kutsi kuvame kuba nemibutsano lemitsatfu lembi etitjalweni tekukhipha imfucuza eveni lami.
Kwekucala ngumjikeleto lombi wemsebenti weludzaka loluphansi (MLVSS/MLSS) kanye nekugcwala kweludzaka lolusetulu; lesibili ngumjikeleto lonelunya welinani lelikhulu lemakhemikhali ekususa iphosphorus lasetjentiswako, kukhishwa kweludzaka loluningi; kwesitsatfu sikhungo sekuhlanta imfucuza sesikhatsi lesidze Kusebenta kwekulayisha kakhulu, imishini ayikhoni kulungiswa, igijima netifo umnyaka wonkhe, lokuholela emjikelezweni lonelunya wekunciphisa emandla ekuhlanta imfucuza.

Umjikeleto lombi wemsebenti weludzaka loluphansi kanye nekuhlanganiswa kweludzaka loluphakeme
Solwati Wang Hongchen wente lucwaningo ngetitjalo letingu-467 tekukhipha imfucuza. Ake sibuke idatha yemsebenti weludzaka kanye nekugcwala kweludzaka: Emkhatsini waletindzawo tekuhlanta imfucuza letingu 467, 61% wetindzawo tekuhlanta imfucuza tine MLVSS/MLSS lengaphansi kwa 0.5, cishe 30 % wetindzawo tekuhlanta tine MLVSS/MLSS lengaphansi kwa 0.4.
Lokucuketfwe kweludzaka lolungu 2/3 wetindzawo tekuhlanta imfucuza kwedlula 4000 mg/L, lokucuketfwe kweludzaka lokungu 1/3 wetindzawo tekuhlanta imfucuza kwedlula 6000 mg/L, kantsi lokucuketfwe kweludzaka lwetikhungo letingu 20 tekuhlanta imfucuza kwedlula 10000.
Yini imiphumela yaletimo letingenhla (umsebenti weludzaka loluphansi, kuhlanganiswa kweludzaka lokusetulu)? Noma sibone tihloko letinyenti tebuchwepheshe letihlatiya liciniso, kepha ngemagama lalula, kunemphumela munye, lokusho kutsi, umphumela wemanti wedlula lizinga.
Loku kungachazwa ngetindlela letimbili. Ngakulolunye luhlangotsi, ngemuva kwekutsi ludzaka luphakeme, kwentela kugwema kufaka ludzaka, kuyadzingeka kutsi kukhuliswe umoya. Kukhulisa linani lemoya ngeke kukhulise kusetjentiswa kwemandla kuphela, kepha kuphindze kukhulise sigaba setilwane. Kukhula kwe oxygen lencibilikile kutawuhlwitsa umtfombo we carbon lodzingekako we denitrification, lokutawutsintsa ngalokucondzile denitrification kanye nemphumela wekususa iphosphorus yeluhlelo lwetintfo letiphilako, lokutawuholela ku N na P lengetulu.
Ngakulolunye luhlangotsi, lokucuketfwe kweludzaka lokusetulu kwenta kutsi lendzawo lesemkhatsini wemanti eludzaka ikhuphuke, futsi loludzaka lulahleka kalula ngekuphuma kwelithange lekugcwala kwesibili, lokutawuvimba iyunithi yekwelapha lesetulu noma kwenta kutsi iCOD ne SS lephumako idlule lizinga.
Ngemuva kwekukhuluma ngemiphumela, asikhulume ngekutsi kungani titjalo letiningi temfucuza tinenkinga yemsebenti weludzaka loluphansi kanye nekuhlanganiswa kweludzaka lolusetulu.
Empeleni, sizatfu sekutsi kube neludzaka loluphakeme ngumsebenti weludzaka loluphansi. Ngenca yekutsi umsebenti weludzaka uphansi, kwentela kwenta ncono umphumela wekwelapha, kuhlanganiswa kweludzaka kumele kukhuliswe. Lomsebenti weludzaka lophansi ubangelwa kutsi emanti lanemtselela anesihlabathi lesikhulu se slag, lesingena eyunithini yekwelapha kwetilwane bese sibutsana kancane kancane, lokutsintsa umsebenti wetintfo letincane.
Kukhona slag kanye nesihlabathi lesiningi emantini langenako. Lokunye kutsi umphumela wekuvimbela we grille awuphuyile kakhulu, kantsi lokunye kutsi ngetulu kwa 90% wetikhungo tekuhlanta imfucuza eveni lami atikakhi emathangi ekuhlanta layinhloko.
Labanye bantfu bangase babute, kungani ungakhi lithange lekugcobisa leliyinhloko? Loku kumayelana nenethiwekhi yemaphayiphi. Kukhona tinkinga letifana nekuhlanganiswa kabi, kuhlanganiswa lokuhlangene, kanye nekuhlanganiswa lokulahlekile kunethiwekhi yemaphayiphi eveni lami. Ngenca yaloko, lizinga lemanti lanemtselela etitjalweni temfucuza ngalokuvamile linetimphawu letintsatfu: kuhlanganiswa lokusetulu kwetintfo leticinile letingaphili (ISS), iCOD lephansi, Silinganiso lesiphansi se C/N.
Kugcwala kwetintfo leticinile letingaphili emantini lanemtselela kuphakeme, lokusho kutsi, lokucuketfwe sihlabatsi kuphakeme kakhulu. Ekucaleni, lithange lekucala lekugcwala linganciphisa letinye tintfo letingaphili, kepha ngenca yekutsi iCOD yemanti lanemtselela iphansi kakhulu, titjalo letiningi tekukhipha imfucuza timane nje Ungakhi lithange lekugcwala leliyinhloko.
Ekuhlaziyeni kwekugcina, umsebenti weludzaka loluphansi ulifa “letitjalo letisindzako kanye nemanethi lalula”.
Sishito kutsi kuhlanganiswa kweludzaka lolusetulu kanye nemsebenti lophansi kutawuholela ku N na P lengetulu kakhulu ku effluent. Ngalesikhatsi, tindlela tekuphendvula tetitjalo letiningi tekukhipha imfucuza kutsi kufakwe imitfombo ye carbon kanye nema flocculants langaphili. Nomakunjalo, kwengeteka kwelinani lelikhulu lemitfombo yekhabhoni yangaphandle kutawuholela ekwandziseni lokunyenti kwekusetjentiswa kwemandla, kantsi kwengeteka kwelinani lelikhulu le flocculant kutawukhicita linani lelikhulu leludzaka lwemakhemikhali, lokutawuholela ekwandziseni kwekuhlanganiswa kweludzaka kanye nekuncipha lokunyenti kwemsebenti weludzaka, lokwakha umbuthano lonelunya.

Umjikeleto lonelunya lapho khona uma kusetjentiswa emakhemikhali ekususa iphosphorus, kukhicitwa kweludzaka lokukhulu.
Kusetjentiswa kwemakhemikhali ekususa iphosphorus sekukhulise umkhicito weludzaka nga 20% kuya ku 30%, noma ngetulu.
Inkinga yeludzaka beyisolo iyinkinga lenkulu yetikhungo tekuhlanta imfucuza iminyaka leminyenti, ikakhulu ngoba kute indlela yekuphuma kweludzaka, noma indlela yekuphuma ayisimami. .
Loku kuholela ekukhuleni kweminyaka yeludzaka, lokuholela esigabeni sekuguga kweludzaka, kanye nekungahambi kahle lokubi kakhulu njengekugcwala kweludzaka.
Loludzaka lolweluliwe lune flocculation lembi. Ngekulahlekelwa kwemanti laphumako lasuka ethangini lesibili lekugcobisa, iyunithi yekuhlanta lesetulu iyavinjelwa, umphumela wekuhlanta uyancishiswa, futsi linani lemanti ekugeza emuva liyakhula.
Kukhula kwemanti ekugeza emuva kutawuholela emiphumeleni lemibili, munye kunciphisa umphumela wekwelapha wesigaba se biochemical lesengcile.
Emanti lamaningi ekugeza emuva abuyiselwa ethangini lekufaka umoya, lokunciphisa sikhatsi sekugcinwa kwe hydraulic sangempela sesakhiwo futsi kunciphisa umphumela wekwelapha wekwelashwa kwesibili;
Kwesibili kutsi kuchubeke kuncishiswe umphumela kucubungula iyunithi kucubungula kujula.
Ngenca yekutsi emanti lamaningi ekugeza emuva kumele abuyiselwe eluhlelweni lwekuhlunga lwekwelapha lolutfutfukile, lizinga lekuhlunga liyakhuphuka bese nemandla ekuhlunga mbamba ayancishiswa.
Umphumela wekwelapha jikelele uba mncane, lokungenta kutsi iphosphorus lephelele kanye ne COD kule effluent kwedlule lizinga. Kute kugwenywe kwendlula lizinga, lesikhungo sekukhipha imfucuza sitawukhulisa kusetjentiswa kwetintfo letisusa i-phosphorus, lokutawukhulisa kakhulu linani leludzaka.
kube ngumbutsano lonelunya.

Umjikeleto lombi wekulayishwa kakhulu kwesikhatsi lesidze kwetitjalo temfucuza kanye nekunciphisa likhono lekuhlanta imfucuza
Kuhlantwa kwemfucuza akunciki kuphela kubantfu, kepha nemishini.
Imishini yekuhlanta imfucuza beyilwa emgceni longembili wekuhlantwa kwemanti sikhatsi lesidze. Nangabe ingalungiswa njalo, tinkinga titawuvela masinyane nobe ngemuva kwesikhatsi. Kepha, etimeni letinyenti, imishini yekukhipha imfucuza ayikhoni kulungiswa, ngoba uma imishini letsite seyimile, emanti lakhishwako kungenteka kutsi adlule lizinga. Ngaphansi kweluhlelo lwetinhlawulo temalanga onkhe, wonkhe umuntfu angeke akhone kukhokha.
Emkhatsini wetindzawo tekuhlanta imfucuza tasemadolobheni letingu 467 letihlolwe nguSolwazi Wang Hongchen, cishe timbili kuletintsatfu tato tinemazinga emtfwalo we hydraulic langetulu kwa 80%, cishe munye kuletintsatfu letingetulu kwa 120%, kantsi tikhungo tekuhlanta imfucuza letingu 5 tingetulu kwa 150%.
Uma lizinga lemtfwalo we hydraulic lingetulu kwa 80%, ngaphandle kwetitjalo letimbalwa letikhulu kakhulu tekuhlanta imfucuza, titjalo tekuhlanta imfucuza jikelele atikhoni kuvala emanti kutsi agcinwe ngesizatfu sekutsi lokuphumako kufinyelela esigabeni, futsi kute emanti lasekelako ema aerators kanye nethange lesibili lekuhlanta imfucuza. Lemishini lephansi ingalungiswa ngalokuphelele noma ifakwe esikhundleni sayo kuphela uma seyiphelile.
Lokusho kutsi, cishe 2/3 wetitjalo tekukhipha imfucuza atikhoni kulungisa imishini ngesizatfu sekucinisekisa kutsi le effluent ihlangabetana nelizinga.
Ngekuya kwelucwaningo lwa Professor Wang Hongchen, sikhatsi sekuphila kwema aerators sivame kuba yiminyaka lengu 4-6, kepha 1/4 wetitjalo tekukhipha imfucuza atizange tente kugcinwa kwemoya-wekukhipha umoya kuma aerators iminyaka lefika ku 6. Lesikhuhlane seludzaka, lesidzinga kukhishwa futsi silungiswe, sivame kungalungiswa umnyaka wonkhe.
Lemishini beyisebenta ngekugula sikhatsi lesidze, futsi likhono lekuhlanta emanti liya ngekuba libi kakhulu. Kute umelane nekucindzeteleka kwekuphuma kwemanti, kute indlela yekuyimisa kute igcinwe. Emjikelezweni lonelunya kangaka, kutawuhlala kuneluhlelo lwekuhlanta imfucuza lolutawubhekana nekuwa.
