| Abstract: | Some common coagulants made in China for tannery wastewater treatment were studied.The result showed that the PFS is a most economical and effective one. When the PAM was added as a coagulant aid, the treatmeat efficiency can be increased remarkably. When coagulative floatation is used as the treatment process, the sulfide in the wastewater can be removed completely and the total chromium in the effluent can be less than 1 mg/L, the COD removal efficiency is 70 % - 80 %. |
