Kusvibiswa kwezvakatipoteredza panguva yekugadzira mapepa echimbuzi

indasitiri yemapepa echimbuzi mukugadzira mvura yetsvina, gasi remarara, marara, zvinhu zvine muchetura uye ruzha zvinogona kukonzera kusvibiswa kwakakomba kwenharaunda, kutonga kwayo, kudzivirira kana kubviswa kwekurapa, kuitira kuti nharaunda yakatenderedza isakanganiswe kana kushomeka. chikamu chakakosha cheindasitiri yemapepa echimbuzi. Indasitiri yemapepa echimbuzi kusvibiswa kwemvura yakakomba, ine, dhiraivha (kazhinji inodarika 300 matani emvura patani yepulp nebepa rechimbuzi), mvura ine tsvina mune yakakwira yezvinhu organic, biochemical oxygen kudiwa (BOD) yakakwirira, yakamiswa solids (SS). ) yakawanda, uye ine zvinhu zvine chepfu, ine ruvara rune kunhuhwirira kwakasiyana, ichiisa mungozi kukura kwakajairika kwezvipenyu zvemumvura, zvinokanganisa maindasitiri, zvekurima uye kupfuya mhuka uye vagari vemvura uye zvakatipoteredza landscaping. Kuunganidzwa nekufamba kwemakore, zvimedu zvakamiswa zvinonyorovesa chiteshi chengarava cherwizi, uye kuburitsa hydrogen sulphide inonhuwa ine muchetura, kukuvadza kunosvika kure.

Kusvibisa masosi Maitiro makuru muindasitiri yemapepa echimbuzi kugadzirira zvinhu, kupuruzira, kudzoreredza alkali, kuchena, kukopa bepa rechimbuzi uye zvichingodaro. Iyo mbishi gadziriro yekugadzira inoburitsa huruva, bark, huni machipisi, huswa hunopera; pulping uye alkali kupora, bleaching process inoburitsa gasi rekubuda, guruva, tsvina yemvura, lime residue, nezvimwe; Toilet paper copying process inoburitsa mvura chena, zvese zvine zvinosvibisa. Kusvibiswa kweindasitiri yemapepa echimbuzi kune zvakatipoteredza kunogona kukamurwa kuita zvikamu zvitatu zvekusvibiswa kwemvura (Tafura 1), kusvibiswa kwemweya (Tafura 2) uye kusvibiswa kwemarara.

Tsvina dzakaoma dzakaora pulp, pulp slag, bark, akaputsika huni machipisi, uswa, huswa midzi, uswa, silica-ine machena madhaka, lime slag, sulfuric iron ore slag, marasha ash slag, nezvimwewo, izvo zvinopinda panzvimbo, leaching. kubva mumvura ine tsvina kusvibisa muviri wemvura uye pasi pevhu. Noise nuisance, idambudziko zvakare guru muindasitiri yemapepa ezvimbuzi.

Kudzivirira kusvibiswa uye kutonga kunogona kukamurwa kuita mapoka maviri: pa-saiti kurapwa kusingakuvadze uye kure-saiti kurapwa kwetsvina.

Yashi pepa rechimbuzi rinoputirwa kuburikidza nemaitiro ese emuviri. Iyo nzira yekugadzira haina kukuvadza kumuviri wemunhu. Chigadzirwa chakapedzwa hachina makemikari anokuvadza masara uye ane hutano uye akachengeteka. Shandisa gasi rechisikigo panzvimbo pemafuta echinyakare kudzivirira kusvibiswa kwehutsi mumhepo. Bvisa maitiro eku bleaching, chengetedza iwo ekutanga ruvara rwechirimwa, kuderedza kushandiswa kwemvura yekugadzira, dzivirira kubuda kwegeji yetsvina, uye chengetedza nharaunda.
