双氧水在硫酸污水中除砷的试验研究

提出以双氧水作为氧化剂去除硫酸污水中砷的方法，并对此方法进行可行性试验的研究。在工业试验中，石灰乳中和预处理工段处理后水中砷含量能由原来的11．80mg／L的平均值降到2．34mg／L，膜过滤器深度处理工段处理后水中含砷量能由原来的0．82mg／L的平均值降到0．13mg／L。

Experimental Study of Removal of Arsenic in Sulfuric Acid Wastewater with Hydrogen Peroxide

i The approach of removing arsenic in the sulfuric acid wastewater with hydrogen peroxide as an oxidant was proposed, which was to conduct a feasibility study experiments. In industrial trials, milk of lime and pre - treated water arsenic section can be increased from 11.80 mg/L, average dropped to 2.34 mg/L, membrane filter depth treatment section arsenic treated water can be increased from the 0. 82 mg/L, and the average was reduced to 0. 13 mg/L.
