Kudzivirira kusvibiswa uye kutonga mukugadzira mapepa echimbuzi kunogona kukamurwa kuita mapoka maviri: mu-chirimwa pane-saiti inonzwika kurapa kwezvakatipoteredza uye kunze-nzvimbo yekurasa tsvina.
Mu-chirimwa kurapwa
Kusanganisira: ① kusimbisa gadziriro (guruva, sediment, peeling, pith, nezvimwewo), kushandiswa kwemvura firimu inounganidza guruva, kuderedza kusvibiswa kweguruva mumusangano wekugadzirira, kuunganidza marara, kupisa kudzoreredza kwesimba rinopisa, sekushandisa makwati, matanda ehuni, bhailer yehuswa; ② kuchengetedza mvura, kudzokorodza kwemvura chena, kakawanda mvura inoshandiswa zvakare; ③ kuvandudza kudhirowa kwekubikira doro dema, kusimbisa manejimendi eiyo counter ikozvino yekugeza chikamu kuti uwedzere huwandu hwezvikamu, kuderedza kuwanda kwekubikira doro dema ne pulp yakabviswa pakusuka, uye shandisa yakakwana yekubikira tsvina yemvura kudzoreredza. yemakemikari uye tekinoroji yesimba remagetsi, senge alkali kudzoreredza, uye kumwe kusvibiswa kwemvura kushandiswa kwakazara. Uye shandisa yakakwana yekubikira tsvina yemvura kudzoreredza kwemakemikari uye tekinoroji yesimba remagetsi, senge alkali kudzoreredza, pamwe nekumwe kushandiswa kwakazara kwemarara emvura tekinoroji; ④ chlorine dioxide kana oxy-alkali bleaching, kana hydrogen peroxide bleaching, kuitira kuderedza tsvina yemvura lignin chloride, chlorophenol nezvimwe zvinosvibisa zvinobuda; ⑤ yakasviba condensate yakacheneswa nenzira yekubvisa chiutsi kuti ishandiswezve kuderedza kuburitswa kwemvura yakasviba yesarufa yakaderedzwa uye organics inonyungudika; ⑥ kuunganidzwa kwedoro dema uye rinodonha doro, Green liquid, chena mvura, ine yemagetsi komputa kutonga kuyera kusungwa kwayo, inodzoserwa otomatiki kune inoenderana tank percussion, kuderedza kuburitsa; ⑦ kudzoreredzwa kwemafibhi akarasika, kuderedza zviri mukati mezvakarembera zvakaomeswa mumvura yakasviba; ⑧ kuvandudza kudzoreredzwa kweturpentine sulphate sipo, kuderedza kuburitswa kwezvinhu zvine chepfu; ⑨ kurapwa kwemarara yakasimba, kushandiswa kwekupisa kudzoreredza kupisa, kushandiswa kwakazara uye kuzadza gomba remhando nhatu dzekurapa; ⑩ kurapwa kweguruva, inogona kushandiswa mukubvisa guruva remagetsi, kubvisa guruva remvura firimu uye kuparadzanisa dutu nemimwe michina; kusvibiswa kwemhepo kugadzirisa Separator nemimwe midziyo; kurapwa kusvibiswa kwemhepo, kuunganidzwa kwegasi rinonhuwa mumusangano wega wega, kusanganisira gasi rinonhuwa rinosimudzwa netsvina condensation mhute yemvura, mushure mekutonhora, kupera simba, kuputika-chiratidzo uye mamwe matanho, anotumirwa kune bhailer, alkali kudzoreredza choto kana lime kiln combustion kurapwa;? Kurapwa kweruzha, tora matanho ekubvisa kuzunguzika, kuvharisa ruzha uye chinja kune yakaderera-ruzha michina.
Kugadziriswa kwemvura yakasviba kunze kwechirimwa
Mvura yakasviba kubva pakubuda kwese kwechirimwa chese inobatwa padanho rekutanga kana rechipiri isati yaiswa mumvura, kana kuti tsvina inoshandiswa kudiridza uye ivhu nemiti zvinoshandiswa kuchenesa mvura yakaraswa. Kurapa kwekutanga kunonyanya kubvisa zvinhu zvakamiswa, nenzira dzakaita sedimentation uye filtration uye air flotation. Miti yega yega inowedzera flocculants kumvura yakasviba kuti ibvise imwe yakanyungudika colloidal organic matter, senge lignin uye pigments. General kurapwa kwekutanga kunogona kubvisa 80 ~ 90% SS uye 20% BOD5. kurapwa kwechipiri kwekurapa kwebiochemical, kunyanya kubvisa BOD5. China ine zvidyarwa zvishoma zvakaiswa kune iyi nzira, kuverenga oxidation madziva, biofilters, bio-turntable uye activated sludge (kusanganisira adsorption uye kuvandudzwa, kukurumidza aeration, kubata oxidation). General kurapwa kwechipiri kunogona kubvisa 60 ~ 95% BOD5. Nyika dzakasimukira, kune zvirimwa zvega zvemvura yetsvina tertiary decolourisation uye kucheneswa kurapwa, kuitira kuti isvike padanho remvura yekunwa, asi mutengo unodhura.
Yashi chimbuzi bepa ndeye 100% haishandisi makemikari fetiraiza uye mishonga yezvipembenene. Maitiro ese anotora tekinoroji yekupuruzira uye isiri-bleaching tekinoroji kuti ive nechokwadi chekuti hapana zvisaririra zvine muchetura uye zvinokuvadza zvakaita semakemikari, mishonga yezvipembenene, simbi inorema, nezvimwewo. Yakaedzwa nesangano rekuongorora rinozivikanwa pasi rose reSSS uye haina muchetura uye zvinokuvadza zvinhu uye carcinogens. Shandisa Izvo zvakachengeteka uye vatengi vanovimbiswa zvakanyanya.
