Kudzivirira nekudzora kusvibiswa kwenzvimbo yekugadzira mapepa echimbuzi kunogona kukamurwa muzvikamu zviviri: kurapwa kwenzvimbo panzvimbo isina njodzi uye kurapwa kwemvura yakasviba kunze kwenzvimbo.
Kurapwa mukati memiti
Zvinosanganisira: ① kusimbisa kugadzirira (guruva, sediment, peeling, pith, nezvimwewo), kushandisa mvura inounganidza guruva, kuderedza kusvibiswa kweguruva muworkshop yekugadzirira, kuunganidza marara, kudzoreredza simba rekupisa, senge kushandisa makwati, machipisi ehuni, bhaira rehuswa; ② kuchengetedza mvura, kudzoreredza mvura chena, kushandisazve mvura kakawanda; ③ kuvandudza kuburitswa kwedoro dema rekubika, kusimbisa manejimendi yechikamu chekuwacha checounter current kuti uwedzere huwandu hwezvikamu, kuderedza huwandu hwedoro dema rekubika nepump yakabviswa kubva pakushambidzwa, uye kushandisa nzira yakakwana yekubika yekudzoreredza makemikari netekinoroji yesimba rekupisa, senge alkali recovery, uye mamwe marara emvura. Uye shandisa nzira yakakwana yekubika yekudzoreredza makemikari netekinoroji yesimba rekupisa, senge alkali recovery, pamwe nekushandiswa kwakazara kwetekinoroji yemvura yakasviba; ④ chlorine dioxide kana oxy-alkali bleaching, kana hydrogen peroxide bleaching, kuitira kuderedza lignin chloride yemvura yakasviba, chlorophenol nezvimwe zvinosvibisa; ⑤ mvura yakasviba inocheneswa nenzira yekuburitsa mhepo kuti ishandiswezve kuderedza kuburitswa kwemvura yakasviba kwesarufa ne organics inonyungudika; ⑥ kuunganidzwa kwemvura inoyerera uye inodonhedza doro dema, mvura yeGreen, mvura chena, ine electronic computer control yekuyera huwandu hwayo, inodzoserwa otomatiki kutangi rinoenderana, kuderedza kuburitswa kwemhepo; ⑦ kudzoserwa kwefibers dzakarasika, kuderedza huwandu hwezvinhu zvakasungirirwa mumvura yakasviba; ⑧ kuvandudza kudzoserwa kwesipo yeturpentine sulphate, kuderedza kuburitswa kwezvinhu zvine chepfu; ⑨ kurapa marara akaomarara, kushandiswa kwekutsva kuti kudzoserwe kupisa, kushandiswa kwakazara uye kuzadza gomba remhando nhatu dzekurapa; ⑩ kurapa guruva, kunogona kushandiswa mukubvisa guruva remagetsi, kubvisa guruva remafirimu emvura uye kuparadzanisa dutu remhepo nezvimwe zvishandiso; Separator yekugadzirisa kusvibiswa kwemhepo nezvimwe zvishandiso; kurapa kusvibiswa kwemhepo, kuunganidzwa kwegasi rinonhuwa muworkshop yega yega, kusanganisira gasi rinonhuwa rinosimudzwa nemhepo yakasviba inonyungudika, mushure mekutonhora, kupera mvura, kudzivirira kuputika nezvimwe zviyero, zvinotumirwa kubhoyira, alkali recovery furnace kana lime kiln combustion treatment;? Kurapa ruzha, tora matanho ekubvisa kudedera, kudzivirira ruzha uye chinja kushandisa michina isina ruzha rwakanyanya.
Kucheneswa kwemvura yakasviba kunze kwefekitori
Mvura yakasviba inobva muburi rese rinobuda muchirimwa chose inocheneswa padanho rekutanga kana rechipiri isati yaburitswa mumvura, kana mvura yakasviba inoshandiswa pakudiridza uye ivhu nemiti zvinoshandiswa kuchenesa mvura yakasviba. Kurapa kwekutanga kunonyanya kubvisa zvinhu zvakasungirirwa, nenzira dzakadai sedimentation uye filtration uye air flotation. Zvirimwa zvega zvega zvinowedzera flocculants mumvura yakasviba kubvisa zvimwe zvezvinhu zvakanyungudutswa zvecolloidal organic, zvakaita se lignin ne pigments. Kurapa kwekutanga kunogona kubvisa 80 ~ 90% SS uye 20% BOD5. Kurapa kwechipiri kwekurapa kwebiochemical, kunyanya kubvisa BOD5. China ine zvirimwa zvishoma zvakashandiswa nenzira iyi, kusanganisira madziva e oxidation, biofilters, bio-turntable uye activated sludge (kusanganisira adsorption uye regeneration, aeration inokurumidza, contact oxidation). Kurapa kwechipiri kunogona kubvisa 60 ~ 95% BOD5. Nyika dzakabudirira dzemaindasitiri, kune zvirimwa zvega zvega zve decolorisation yemvura yakasviba uye kuchenesa, kuitira kuti isvike padanho remvura yekunwa, asi mutengo wacho unodhura.
Mapepa ekugezera eYashi haana kushandiswa mishonga yemakemikari nemishonga yezvipembenene. Maitiro ese anoshandisa tekinoroji ye physical pulping uye kwete bleaching kuti ive nechokwadi chekuti hapana zvinhu zvine chepfu uye zvinokuvadza zvakaita semakemikari, mishonga yezvipembenene, simbi dzinorema, nezvimwewo. Yakaedzwa nesangano rekuyedza rinozivikanwa pasi rose reSGS uye haina zvinhu zvine chepfu uye zvinokuvadza uye kenza. Kushandisa Yakachengeteka uye vatengi vane chivimbo chakawanda.
