Abstract

Owing to its highly concentrated chroma and complicated organic ingredients,dyeing wastewater from a chemical plant in Hebei has been studied and a good result id obtained after using the treatment technocs of PFS+MS two stages of coagulation -hydrolysis -contact oxidation -slag adsorption.After this tratment,the chroma of the wastewater drops form 11111 to 80,the CODCrfrom 7762mg/L to 310mg/L,and the rremoval rate is 99.3% and 96.0% respectively.
