A discussion about the sewage treatment of carbide ash

Abstract：The thesis is a discussion about the technique and mechanism of treatment of the alkaline waste water with high volume of sulfide and Calcium, and about correlative experiments. The result shows that it is feasible to use NaClO and O2 as compound oxidant, and MnSO4 as catalyzer. The Carbide ash sewage in the Acetylene station of Chemical and Power Company in Jiaozuo City can be reused after catalysis and oxidation if the pH value is 95 or so, the addition of MnSO4 is 4% of that of S^2－, the ratio of gas and water, when blowing, is 5, and the reaction temperature is under 45℃.
