Mazuva ano, kuziva kwevanhu kwezvakatipoteredza kuri kuwedzera zvishoma nezvishoma, uye kushevedzera kwekuchengetedzwa kwezvakatipoteredza kuri kuramba kuchiwedzera.Mukuita kwekugadzirwa kwemaindasitiri, pachave nekuwanda kwemvura yakasviba, tsvina, mvura ine chepfu, nezvimwe, izvo zvinoda kurapwa nenzira dzakakosha.Kana isina kubatwa nemazvo, zviri nyore kukonzera kusvibiswa kwezvakatipoteredza, uye kunyange kukanganisa nharaunda iri pedyo yezvakatipoteredza.kumatambudziko ehutano hwevanhu.Saka majenareta anoita sei nenyaya dzekusvibisa idzi?
Semuyenzaniso, zvemagetsi fekitari sewage kuchenesa.Zvinoenderana neakasiyana mafekitori emagetsi, mabhodhi edunhu uye zvikamu zvemagetsi zvinoda kucheneswa panguva yekugadzira.Munguva yekuchenesa, mvura yakakura-yakasvibiswa ichaonekwa.Mvura yetsvina iyi ine tin, lead, uye cyanide yakawanda.Makemikari, hexavalent chromium, trivalent chromium, nezvimwewo, uye organic wastewater zvakare yakaoma uye inoda kurapwa kwakasimba isati yaburitswa.Kugadzirisa dambudziko iri, vamwe vagadziri vemagetsi vachashandisa majenareta ehutsi kuita matatu-effect evaporation kuchenesa kusvibiswa kwemvura.
Kana iyo matatu-effect evaporator iri kushanda, jenareta rehutsi rinodiwa kuti ripe simba rekupisa nekumanikidza.
Mumamiriro ekutenderera kutonhora, mutsi wechipiri unogadzirwa nemvura yakasvibiswa ichakurumidza kuchinjwa kuva mvura yakanyungudutswa, uye mvura yakanyungudutswa inogona kuramba ichienderera mberi Mvura inobudiswa uye inoshandiswa zvakare mudziva.Iyi nzira inogona kuwanikwa chete nemagetsi emagetsi.Paunenge uchiita matatu-maitiro ekugadziriswa kwetsvina yetsvina, hupfu hwakakwana uye kuenderera kwemvura kunodiwa, uye jenareta remhepo rinogona kushanda maawa makumi maviri nemana pazuva risingabudise chero tsvina.Iyo yasara kubudisa gasi uye tsvina yemvura.
Kutaura zvazviri, kusvibiswa kwemvura kunotyisa zvikuru, kunyanya kusati kwaita maindasitiri asati afambira mberi.Mvura yemurwizi yainwa yakananga.Zvaitapira uye zvinonaka.Unoonawo kuti mvura yemurwizi iyi yainyatsochena.Asi mvura yerwizi yanhasi ine Heavy metals nezvimwe zvinosvibisa chepfu, pamwe nezvinhu zviri pa periodic table, zvinogona kuwanikwa munzizi, uye kusvibiswa kwemvura kwakanyanya.
Mazuva ano, pasi pekutonga kwakasimba kwehurumende, mamiriro ekusvibiswa kwemvura achagadziriswa zvakanaka.Nekufambira mberi kwesainzi uye tekinoroji uye kuvandudzwa kweruzivo rwezvakatipoteredza, vanhu vachange vakangwarira pamusoro pekugadziriswa kwetsvina nemvura yetsvina.
Iyo steam jenareta haingoshandisi matatu-effect evaporator kuchenesa tsvina, asi zvakare shandisa vacuum evaporation uye kudzikamisa kuburitsa tsvina yemumaindasitiri kuita gasi uye kuisa zvinosvibisa.Inogona zvakare kuita distillation uye condensation processing, ichibvumira iyo evaporated gasi kunyungudutswa uye kunyungudutswa kuti iparadzanise, uye iyo yakapatsanurwa mvura kuti inyudzwe, uyezve 90% yemvura yakasvibiswa inogona kushandiswa zvakare.Inogonawo kuisa pfungwa pazvinhu zvinosvibisa.Mushure mekunge tsvina yanyungudutswa, zvinosvibisa zvasara zvinosvibisa.Panguva ino, inogona kuiswa mukati uye zvino zvinosvibisa zvinogona kubudiswa.
