Pharmaceutical industrial wastewater feem ntau suav nrog cov tshuaj tua kab mob tsim cov dej khib nyiab, cov tshuaj hluavtaws tsim cov dej khib nyiab, suav patent tshuaj tsim cov dej khib nyiab thiab ntxuav dej thiab yaug cov dej khib nyiab hauv cov txheej txheem tsim khoom ntawm ntau yam kev npaj.
Nws cov dej khib nyiab yog cov yam ntxwv ntawm cov khoom sib txuam, cov ntsiab lus organic siab, muaj kuab lom, cov xim sib sib zog nqus thiab cov ntsev ntsev, tshwj xeeb tshaj yog cov khoom tsis zoo biochemical thiab tsis sib xws, uas nyuaj rau kev kho cov dej khib nyiab.
Tam sim no, cov kev siv physicochemical kev kho mob feem ntau suav nrog coagulation, huab cua flotation, adsorption, ammonia stripping, electrolysis, ion pauv thiab membrane sib cais.
Coagulation kev kho mob ntawm cov dej khib nyiab yog siv dav siv dej zoo hauv tsev thiab txawv teb chaws. Nws yog dav siv nyob rau hauv pretreatment thiab tom qab kho cov dej khib nyiab, xws li polyaluminium chloride thiab polyferric sulfate. Tus yuam sij ntawm kev ua haujlwm siab coagulation kev kho mob yog xaiv kom raug thiab ntxiv cov coagulants nrog kev ua tau zoo.
