Ukuthintela nokulawula ungcoliseko kwinkqubo yokwenza iphepha lendlu yangasese kunokwahlulwahlulwa kube ngamacandelo amabini: unyango olungenabungozi kokusingqongileyo olukwizityalo kunye nonyango lwamanzi amdaka olungaphandle kwendawo.
Unyango olusetyenziswa kwizityalo
Kubandakanya: ① ukuqinisa ukulungiswa (uthuli, intlenga, ukuxobuka, i-pith, njl.njl.), ukusetyenziswa komqokeleli wothuli lwefilimu yamanzi, ukunciphisa ungcoliseko lothuli kwindawo yokulungisa, ukuqokelelwa kwenkunkuma, ukubuyiselwa kwamandla obushushu, njengokusetyenziswa kwamaxolo, iitships zeenkuni, ibhoyila yokutshisa ingca; ② ukugcinwa kwamanzi, ukuphinda kusetyenziswe amanzi amhlophe, amaxesha amaninzi ukuphinda kusetyenziswe amanzi; ③ ukuphucula ukukhutshwa kotywala obumnyama bokupheka, ukuqinisa ulawulo lwecandelo lokuhlamba elikwikhawuntara ukwandisa inani lamacandelo, ukunciphisa ubungakanani botywala obumnyama bokupheka kunye ne-pulp esusiweyo ekuhlanjweni, kunye nokusebenzisa ukubuyiswa kolwelo olungcolileyo lokupheka olugqibeleleyo lweekhemikhali kunye netekhnoloji yamandla obushushu, njengokubuyiswa kwe-alkali, kunye nokusetyenziswa okubanzi kolwelo olungcolileyo. Kwaye sebenzisa ukubuyiswa kolwelo olungcolileyo lokupheka olugqibeleleyo lweekhemikhali kunye netekhnoloji yamandla obushushu, njengokubuyiswa kwe-alkali, kunye nokusetyenziswa okubanzi kobuchwepheshe bolwelo olungcolileyo; ④ i-chlorine dioxide okanye i-oxy-alkali bleaching, okanye i-hydrogen peroxide bleaching, ukuze kuncitshiswe i-lignin chloride yamanzi amdaka, i-chlorophenol kunye nezinye izinto ezinobuthi ezikhutshwayo; ⑤ i-condensate engcolileyo ecociwe ngendlela yokukhupha umphunga ukuze isetyenziswe kwakhona ukunciphisa ukukhutshwa kwamanzi amdaka kwesalfure kunye nezinto eziphilayo ezinyibilikayo; ⑥ ukuqokelelwa kotywala obumnyama obuphumayo kunye nobomileyo, ulwelo oluluhlaza, ulwelo olumhlophe, olunolawulo lwekhompyutha ye-elektroniki ukulinganisa uxinzelelo lwayo, luthunyelwa ngokuzenzekelayo kwi-percussion yetanki ehambelanayo, ukunciphisa ukukhutshwa; ⑦ ukubuyiswa kweefayibha ezilahlekileyo, ukunciphisa umxholo wezinto eziqinileyo ezixhonyiweyo emanzini amdaka; ⑧ ukuphucula ukubuyiswa kwesepha ye-turpentine sulphate, ukunciphisa ukukhutshwa kwezinto ezinobuthi; ⑨ unyango lwenkunkuma eqinileyo, ukusetyenziswa kokutshisa ukubuyisela ubushushu, ukusetyenziswa ngokupheleleyo kunye nokugcwalisa umngxuma weentlobo ezintathu zonyango; ⑩ unyango lothuli, lungasetyenziswa ekususeni uthuli ngombane, ukususa uthuli lwefilimu yamanzi kunye nokwahlula-hlula kwenkanyamba kunye nezinye izixhobo; ukucubungula ungcoliseko lomoya I-Separator kunye nezinye izixhobo; unyango longcoliseko lomoya, ukuqokelelwa kwegesi enukayo kwindawo nganye yokusebenzela, kubandakanya igesi enukayo ephakanyiswe ngumphunga wamanzi omdaka, emva kokupholisa, ukuphelelwa ngamanzi emzimbeni, ukuthintela ukuqhuma kunye nezinye iindlela, ezithunyelwa kwibhoyila, i-alkali recovery furnace okanye unyango lokutsha kwi-lime kiln;? Unyango lwengxolo, thabatha amanyathelo okuphelisa ukungcangcazela, ukuthintela isandi kwaye utshintshele kwizixhobo ezingenangxolo iphantsi.
Unyango lwamanzi amdaka ngaphandle kwesityalo
Amanzi amdaka avela kwindawo yonke yokukhupha isityalo aphathwa kwinqanaba eliphambili okanye lesibini ngaphambi kokuba akhutshwe emanzini, okanye amanzi amdaka asetyenziselwa ukunkcenkceshela kwaye umhlaba nezityalo zisetyenziselwa ukucoca amanzi amdaka. Unyango oluphambili lususa ikakhulu izinto ezixhonyiweyo, ngeendlela ezifana nokuthuthwa kunye nokucoca kunye nokubhabha komoya. Izityalo ngazinye zongeza ii-flocculants emanzini amdaka ukususa ezinye zezinto eziphilayo ezinyibilikisiweyo ze-colloidal, ezifana ne-lignin kunye neepigment. Unyango oluphambili oluqhelekileyo lunokususa i-80 ~ 90% SS kunye ne-20% BOD5. Unyango lwesibini lonyango lwe-biochemical, ikakhulu ukususa i-BOD5. I-China inezityalo ezimbalwa ezisetyenzisiweyo kule ndlela, kubalwa amachibi e-oxidation, ii-biofilters, i-bio-turntable kunye ne-activated sludge (kubandakanya ukufunxa kunye nokuhlaziya, ukungenisa umoya ngokukhawuleza, i-contact oxidation). Unyango oluqhelekileyo lwesibini lunokususa i-60 ~ 95% BOD5. Amazwe aphuhlileyo kwezoshishino, kukho izityalo ngazinye zokususa umbala emanzini amdaka kwinqanaba eliphezulu kunye nonyango lokucoca, ukuze kufikelelwe kwinqanaba lamanzi okusela, kodwa ixabiso libiza kakhulu.
Iphepha langasese leYashi alisebenzisi izichumisi zeekhemikhali kunye nezibulali-zinambuzane. Le nkqubo isebenzisa ubuchwepheshe bokugquma ngokwasemzimbeni kunye nobokungagubungeli ukuqinisekisa ukuba akukho zintsalela zinobungozi neziyingozi ezifana neekhemikhali, izibulali-zinambuzane, iintsimbi ezinzima, njl. Ivavanyiwe yi-arhente yovavanyo eyaziwayo kwihlabathi liphela i-SGS kwaye ayinazo izinto ezinobungozi neziyingozi kunye nee-carcinogens. Sebenzisa Ikhuselekile kwaye abathengi baqinisekile ngakumbi.
