| Abstract: | Three kinds of coagulants including PAC, Al2(SO4)3 and PFS are chosen to treat wastewater from chemical industry with high concentration of COD. First of all, the optimal use levels of two kinds of coagulants are tested, then the suitable pH value is decided. PAC is the most suitable coagulant through comparing the results. The concentration of CODcr of the wastewater been treated by PAC is 349.7mg/l, and the removal rate of CODcr reaches 66.7%. |
