Bhizinesi remapepa echimbuzi mukugadzira mvura yakasviba, gasi rakasviba, marara akasara, zvinhu zvine chepfu uye ruzha zvinogona kukonzera kusvibiswa kwakanyanya kwezvakatipoteredza, kudzora, kudzivirira kana kubvisa kurapwa, kuitira kuti nharaunda yakapoteredza isakanganiswa kana kusakanganiswa zvakanyanya, rave chikamu chakakosha cheindasitiri yemapepa echimbuzi. Bhizinesi remapepa echimbuzi kusvibiswa kwemvura kwakanyanya, nekuyerera kwemvura (kazhinji inopfuura matani mazana matatu emvura patani yepulp nepepa rechimbuzi), mvura yakasviba ine huwandu hwakawanda hwezvinhu zvipenyu, kudiwa kweokisijeni yemakemikari (BOD) kwakakwira, suspended solids (SS) yakawanda, uye ine zvinhu zvine chepfu, zvine ruvara rune hwema hwakasiyana, zvichiisa panjodzi kukura kwezvisikwa zvemumvura, zvichikanganisa maindasitiri, zvekurima nekuchengeta mhuka nevagari vemvura nemasango ezvakatipoteredza. Kuunganidzwa kwemakore, suspended solids kuchasvibisa chiteshi chegungwa, uye kuburitsa hydrogen sulfide ine chepfu, kukuvadza kukuru.
Manyuko ekusvibiswa Maitiro makuru muindasitiri yemapepa echimbuzi ndeekugadzirira zvinhu zvisina kuchena, kupwanya, kudzoreredza alkali, kupwanya, kukopa mapepa echimbuzi nezvimwewo. Maitiro ekugadzira zvinhu zvisina kuchena anogadzira guruva, makwati, machipisi ehuni, magumo ehuswa; kupwanya nekupora alkali, kupwanya kunogadzira gasi reutsi, guruva, mvura yakasviba, marara eraimu, nezvimwewo; maitiro ekunyora mapepa echimbuzi anogadzira mvura chena, zvese zvine tsvina. Kusvibiswa kweindasitiri yemapepa echimbuzi kunharaunda kunogona kukamurwa muzvikamu zvitatu zvekusvibiswa kwemvura (Tafura 1), kusvibiswa kwemhepo (Tafura 2) uye kusvibiswa kwetsvina yakasimba.
Marara akaoma ivhu rinoora, slag ye pulp, makwati, machipisi ehuni akapwanyika, huswa, midzi yehuswa, huswa, matope machena ane silica, lime slag, sulfuric iron ore slag, coal ash slag, nezvimwewo, zvinopinda panzvimbo iyi, zvichibuda mumvura ine madhaka zvichisvibisa mvura nemvura yepasi. Dambudziko reruzha idambudziko guru muindasitiri yepepa rechimbuzi.
Kudzivirira nekudzora kusvibiswa kunogona kukamurwa muzvikamu zviviri: kurapwa kusina njodzi panzvimbo uye kurapwa kwemvura yakasviba kunze kwenzvimbo.
Pepa rechimbuzi reYashi rinopurwa mukati memaitiro ese emuviri. Maitiro ekugadzira haakuvadzi muviri wemunhu. Chigadzirwa chapera hachina masara emakemikari anokuvadza uye chine hutano uye chakachengeteka. Shandisa gasi rechisikigo panzvimbo pemafuta echinyakare kudzivirira kusvibiswa kweutsi mumhepo. Bvisa maitiro ekupukuta, chengetedza ruvara rwepakutanga rweshinda dzemiti, deredza kushandiswa kwemvura, dzivisa kuburitswa kwetsvina inopukuta, uye chengetedza nharaunda.
