Abstract

It is shown by the experimental results that the combined process of micro-flocculation and ultrafiltration has relatively good effect on the removal of the CODCr,turbidity and LAS from bathing wastewater.When the quantity of polymerization aluminum chloride(PAC)is 20 mg/Lt,he experimental result shows that the removal rates of CODCr,turbidity and LAS by this process are 75%~80%,94%~97% and 74%~83% respectively,and its water quality could reach the requirements of city wastewater reuse indexes.
