Abstract:
A comprehensive t reatment procedure for the wastes from stearates production w as proposed. It is composed of several parts, including the removement of the organic pollutants ( COD) in the coaste w ater by ox idat ion w ith 100 mg / L ClO2 dosag e, the removement of the tox ic heavy metals( i. e. , Pb 2+ , Cd 2+ , Zn 2+ ) in the w ater by precipitat ion at the pH of 11 or higher, the removement of the dust and the SO2 in the flue g as by contact w ith the w ater above, and at last , the suspended substances were removed by coagulation. With the simple equipment and the convenient operations, the operat ion results for months have show n that it is effect ive, economical and pract icable.
