Uthintelo longcoliseko kunye nolawulo kwinkqubo yokwenziwa kwephepha lendlu yangasese lunokwahlulwa lube ziindidi ezimbini: kwisityalo esikwisiza sonyango olulungileyo lokusingqongileyo kunye nokucocwa kwamanzi amdaka ngaphandle kwendawo.
Unyango lwezityalo
Kubandakanya: ① ukomeleza ukulungiswa (uthuli, intlenga, ukuxobula, i-pith, njl. njl.), ukusetyenziswa kwefilimu yamanzi umqokeleli wothuli, ukunciphisa ungcoliseko lothuli kwindawo yokulungiselela, ukuqokelelwa kwenkunkuma, ukutsha kwakhona kwamandla ashushu, njengokusetyenziswa kwexolo, iitshiphusi zokhuni, ibhoyila yesitshisi sengca; ② ulondolozo lwamanzi, ukurisayikilisha kwamanzi amhlophe, amaxesha amaninzi amanzi aphinda asetyenziswe; ③ ukuphucula ukutsalwa kotywala obumnyama, ukomeleza ulawulo lwendawo yokuhlamba yangoku ukwandisa inani lamacandelo, ukunciphisa umthamo wokupheka utywala obumnyama kunye ne-pulp esusiwe ekuhlambeni, kunye nokusebenzisa inkunkuma yokupheka egqibeleleyo yokubuyisela ulwelo lweekhemikhali kunye nobuchwepheshe bamandla obushushu, obufana nokubuyiswa kwe-alkali, kunye nokunye ukusetyenziswa kolwelo oluyinkunkuma. Kwaye usebenzise inkunkuma yokupheka egqibeleleyo yokubuyisela ulwelo lweekhemikhali kunye nobuchwepheshe bamandla obushushu, njengokubuyiswa kwealkali, kunye nolunye usetyenziso olubanzi lwetekhnoloji yolwelo lwenkunkuma; 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 eziyityhefu; ⑤ i-condensate emdaka ecocwe ngendlela yokutsalwa komphunga ukuze iphinde isetyenziswe ukunciphisa ukukhutshwa kwamanzi amdaka kwisalfure encitshisiweyo kunye nezinto eziphilayo ezinyibilikayo; ⑥ ingqokelela yotywala obuvuzayo kunye nokuthontsiza kotywala, ulwelo oluluhlaza, ulwelo olumhlophe, nolawulo lwekhompyutha ye-elektroniki ukulinganisa ukuxinana kwalo, luthunyelwe ngokuzenzekelayo emva kwi-tank ehambelana ne-percussion, ukunciphisa ukukhutshwa; ⑦ ukubuyiswa kweentsinga ezilahlekileyo, ukunciphisa umxholo wezinto eziqinileyo ezimisiweyo kumanzi amdaka; ⑧ ukuphucula ukubuyiswa kwesepha ye-turpentine sulphate, ukunciphisa ukukhutshwa kwezinto ezinobuthi; ⑨ unyango lwenkunkuma eqinileyo, ukusetyenziswa kokutshisa ukubuyisela ubushushu, ukusetyenziswa okubanzi kunye nokuzalisa umngxuma weentlobo ezintathu zonyango; ⑩ unyango lothuli, lunokusetyenziswa ekususeni uthuli lombane, ukususwa kothuli lwefilimu yamanzi kunye nesahluli se-cyclone kunye nezinye izixhobo; ukusetyenzwa kongcoliseko lomoya Isahluli kunye nezinye izixhobo; unyango longcoliseko lomoya, ingqokelela yerhasi enevumba elibi kwiworkshop nganye, kubandakanywa irhasi enevumba elibi eliphakanyiswe ngumphunga wamanzi omdaka, emva kokupholisa, ukuphelelwa ngamanzi emzimbeni, ubungqina bokudubula kunye neminye imilinganiselo, ithunyelwe kwibhoyila, kwiziko lokubuyisela ialkali okanye unyango lokutshiswa kwekalika; Unyango lwengxolo, thatha amanyathelo okuphelisa ukungcangcazela, ukugquma kwesandi kunye nokutshintshela kwisixhobo esinengxolo ephantsi.
Ukucocwa kwamanzi amdaka ngaphandle kwesityalo
Amanzi amdaka aphuma kwindawo yokukhupha isityalo sonke aphathwa kwinqanaba lokuqala okanye lesibini ngaphambi kokuba akhutshelwe kumzimba wamanzi, okanye amanzi amdaka asetyenziselwa ukunkcenkceshela kwaye umhlaba kunye nezityalo zisetyenziselwa ukucoca amanzi amdaka. Unyango olusisiseko lususa ikakhulu izinto ezimisiweyo, kunye neendlela ezinje ngentlenga kunye nokuhluza kunye ne-air flotation. Izityalo ezizimeleyo zongeza i-flocculants kumanzi amdaka ukuze kususwe enye into enyityilisiweyo ye-colloidal organic matter, efana ne-lignin kunye nee-pigments. Unyango oluphambili oluqhelekileyo lunokususa i-80 ~ 90% SS kunye ne-20% BOD5. unyango lwesibini kunyango lwe-biochemical, ngokukodwa ukususa i-BOD5. I-China inezityalo ezimbalwa ezisetyenzisiweyo kule ndlela, ukubala amachibi e-oxidation, i-biofilters, i-bio-turntable kunye ne-activated sludge (kubandakanya i-adsorption kunye nokuvuselelwa, i-aeration ekhawulezayo, i-oxidation yoqhagamshelwano). Unyango oluqhelekileyo lwesibini lunokususa i-60 ~ 95% BOD5. kumazwe aphuhlileyo kwimizi-mveliso, kukho izityalo ezizimeleyo zokucolwa kombala wamanzi amdaka aphakamileyo kunye nokucoca, ukuze kufikelelwe kwinqanaba lamanzi okusela, kodwa ixabiso liyabiza.
Iphepha langasese le-Yashi yi-100% ayisebenzisi izichumisi zeekhemikhali kunye ne-pesticides. Yonke inkqubo ithatha iteknoloji ye-pulping kunye ne-non-bleaching technology ukuze kuqinisekiswe ukuba akukho zintsalela ezinobuthi neziyingozi ezifana neekhemikhali, izibulala-zinambuzane, isinyithi esinzima, njl. Ukusetyenziswa Kukhuselekile kwaye abathengi baqiniseke ngakumbi.
