Indasitiri mamiriro uye maitiro etannery wastewater
Muhupenyu hwezuva nezuva, zvigadzirwa zvematehwe zvakadai semabhegi, shangu dzematehwe, mbatya dzematehwe, sofa dzematehwe, nezvimwewo. Mumakore achangopfuura, indasitiri yematehwe yakakurumidza kukura. Panguva imwecheteyo, kubudiswa kwetsvina yematehwe zvishoma nezvishoma kwave kune imwe yemanyuko akakosha ekusvibiswa kweindasitiri.
Kuchenesa kunowanzo sanganisira matanho matatu ekugadzirira, kuomesa uye kupedza. Muchikamu chekugadzirira kusati kwapisa, tsvina inonyanya kubva pakushambidza, kunyura, kubvisa bvudzi, kuisa liming, deliming, softening uye degreasing; izvo zvinosvibisa zvakanyanya zvinosanganisira marara emarara, inorganic tsvina uye organic makomisheni. Mvura yetsvina muchikamu chekusukuta kazhinji inobva mukuwacha, kunhonga, uye kusukuta; izvo zvinosvibisa zvakanyanya inorganic munyu uye heavy metal chromium. Mvura yakasvibiswa muchikamu chekupedzisa inonyanya kubva pakushambidza, kusvina, kudhaya, mafuta emvura uye kubvisa tsvina, etc. Zvinosvibisa zvinosanganisira dhayi, mafuta uye organic compounds. Naizvozvo, mvura yetsvina yematehwe ine hunhu hwehuwandu hwemvura yakakura, shanduko huru mumhando yemvura uye huwandu hwemvura, kusvibiswa kwakanyanya, yakakwira alkalinity, yakakwira chroma, yakakwira yezvakarembera zvakamira, yakanaka biodegradability, nezvimwewo, uye ine humwe huturu.
Sulfur-ine tsvina yemvura: Liming tsvina yemvura inogadzirwa neash-alkali dehairing mukugadzira tanning uye inopindirana newashing process tsvina yemvura;
Degreasing wastewater: Mukuita degreasing yekutsvaira nekugadziriswa fur, tsvina yemvura inoumbwa nekurapa dehwe mbishi nemafuta nesurfactant uye inoenderana netsvina yemvura yekuwachisa.
Chromium-ine tsvina yemvura: tsvina yechromium chinwiwa chinogadzirwa mu chrome tanning uye chrome retanning maitiro, uye inoenderana netsvina mukugadzira maitiro.
Yakazara tsvina yemvura: izwi rakajairwa remvura yetsvina yakasiyana-siyana inogadzirwa nemabhizinesi ekutsvaira uye makushe ekugadzira kana nzvimbo dzepakati pekugadzirisa, uye yakananga kana zvisina kunanga kumapurojekiti ekuchenesa mvura yetsvina (senge nzira yekugadzira mvura yetsvina, tsvina yemumba mumafekitori).
