Ukuvimbela nokulawula ukungcola enkambisweni yokwenza iphepha langasese kungahlukaniswa ngezigaba ezimbili: ukwelashwa okungenangozi emvelweni ezitshalweni kanye nokwelashwa kwamanzi amdaka ngaphandle kwendawo.
Ukwelashwa ngaphakathi kwezitshalo
Kufaka phakathi: ① ukuqinisa ukulungiswa (uthuli, inhlabathi, ukuxebuka, i-pith, njll.), ukusetshenziswa komqoqi wothuli lwefilimu yamanzi, ukunciphisa ukungcola kothuli endaweni yokulungisa, ukuqoqwa kwemfucuza, ukubuyiselwa kwamandla okushisa ngokushisa, njengokusetshenziswa kwamagxolo, ama-chips okhuni, ibhoyila yokushisa utshani; ② ukongiwa kwamanzi, ukuphinda usebenzise amanzi amhlophe, izikhathi eziningana ukuphinda usebenzise amanzi; ③ ukuthuthukisa ukukhishwa kotshwala obumnyama bokupheka, ukuqinisa ukuphathwa kwesigaba sokuwasha samandla angaphandle ukuze kwandiswe inani lezingxenye, ukunciphisa inani lotshwala obumnyama bokupheka nge-pulp esusiwe ekuhlanzweni, nokusebenzisa ukubuyiswa koketshezi olungcolile lokupheka oluphelele lwamakhemikhali nobuchwepheshe bamandla okushisa, njengokubuyiswa kwe-alkali, kanye nokusetshenziswa okuphelele koketshezi olungcolile. Futhi sebenzisa ukubuyiswa koketshezi olungcolile lokupheka oluphelele lwamakhemikhali nobuchwepheshe bamandla okushisa, njengokubuyiswa kwe-alkali, kanye nokusetshenziswa okuphelele kobuchwepheshe boketshezi olungcolile; ④ i-chlorine dioxide noma i-oxy-alkali bleaching, noma i-hydrogen peroxide bleaching, ukuze kuncishiswe i-lignin chloride yamanzi angcolile, i-chlorophenol kanye nokunye ukukhishwa okunobuthi emanzini angcolile; ⑤ i-condensate engcolile ehlanzwa ngendlela yokukhipha umusi ukuze isetshenziswe kabusha ukuze kuncishiswe ukukhishwa kwamanzi angcolile kwe-sulfur encishisiwe kanye nezinto eziphilayo ezincibilikayo; ⑥ ukuqoqwa kotshwala obumnyama obugelezayo kanye noketshezi oluconsayo, uketshezi oluluhlaza, uketshezi olumhlophe, olunokulawulwa kwekhompyutha kagesi ukuze kulinganiswe ukuhlushwa kwalo, kuthunyelwa ngokuzenzakalelayo ekushayweni kwethangi elifanele, ukuze kuncishiswe ukukhishwa; ⑦ ukubuyiswa kwemicu elahlekile, ukunciphisa okuqukethwe kwezinto eziqinile ezilengisiwe emanzini angcolile; ⑧ ukuthuthukisa ukubuyiswa kwensipho ye-turpentine sulphate, ukunciphisa ukukhishwa kwezinto ezinobuthi; ⑨ ukwelashwa kwemfucuza eqinile, ukusetshenziswa kokushisa ukuze kubuyiselwe ukushisa, ukusetshenziswa okuphelele nokugcwalisa umgodi wezinhlobo ezintathu zokwelapha; ⑩ ukwelashwa kothuli, kungasetshenziswa ekususweni kothuli ngogesi, ukususwa kothuli lwefilimu yamanzi kanye nokuhlukanisa isivunguvungu kanye neminye imishini; i-Separator yokucubungula ukungcola komoya kanye neminye imishini; ukwelashwa kokungcola komoya, ukuqoqwa kwegesi enukayo endaweni ngayinye yokusebenzela, kufaka phakathi igesi enukayo ephakanyiswe umhwamuko wamanzi ongcolile, ngemva kokupholisa, ukuphelelwa amanzi emzimbeni, ukuvimbela ukuqhuma kanye nezinye izindlela, ezithunyelwa kubhoyila, isithando sokubuyisa i-alkali noma ukwelashwa kokushiswa kwesitofu sikalime;? Ukwelashwa komsindo, thatha izinyathelo zokuqeda ukudlidliza, ukuvimbela umsindo bese ushintshela kumishini enomsindo ophansi.
Ukwelashwa kwamanzi angcolile ngaphandle kwesitshalo
Amanzi angcolile avela endaweni yonke yokukhipha amanzi esitshalweni sonke aphathwa ezingeni lokuqala noma lesibili ngaphambi kokuba akhishwe emanzini, noma amanzi angcolile asetshenziselwa ukunisela futhi inhlabathi nezitshalo zisetshenziselwa ukuhlanza amanzi angcolile. Ukwelashwa okuyinhloko kususa kakhulu izinto ezilengayo, ngezindlela ezifana nokuthungwa kanye nokuhlunga kanye nokuntanta komoya. Izitshalo ngazinye zengeza ama-flocculant emanzini angcolile ukuze kususwe ezinye zezinto eziphilayo ezincibilikisiwe ze-colloidal, njenge-lignin kanye nemibala. Ukwelashwa okujwayelekile okuyinhloko kungasusa ama-80 ~ 90% SS kanye nama-20% BOD5. Ukwelashwa kwesibili kokwelashwa kwamakhemikhali, ikakhulukazi ukususa i-BOD5. IShayina inezitshalo ezimbalwa ezisetshenzisiwe kule ndlela, kubalwa amachibi e-oxidation, ama-biofilters, i-bio-turntable kanye ne-activated sludge (kufaka phakathi ukumuncwa nokuvuselelwa, ukuphefumula okusheshayo, i-contact oxidation). Ukwelashwa okujwayelekile kwesibili kungasusa ama-60 ~ 95% BOD5. Amazwe athuthukile ezimboni, kunezitshalo ngazinye zokususa umbala emanzini angcolile kanye nokwelashwa kokuhlanza, ukuze kufinyelelwe ezingeni lamanzi okuphuza, kodwa izindleko ziyabiza.
Iphepha langasese le-Yashi liyi-100% alisebenzisi umanyolo wamakhemikhali kanye nezibulala-zinambuzane. Yonke inqubo isebenzisa ubuchwepheshe bokuhlikihla ngokomzimba kanye nobuchwepheshe bokungaphuzi ukuze kuqinisekiswe ukuthi azikho izinsalela ezinobuthi neziyingozi ezifana namakhemikhali, izibulala-zinambuzane, izinsimbi ezisindayo, njll. Lihlolwe yi-ejensi yokuhlola egunyaziwe emhlabeni wonke i-SGS futhi alinazo izakhi ezinobuthi neziyingozi kanye nezinto ezibangela umdlavuza. Sebenzisa Liphephile futhi abathengi baqiniseka kakhulu.
