摘要
对被黄磷污染的饮用水进行小试研究,采用消毒剂曝气氧化工艺,在对水体消毒的同时,把黄磷氧化成磷酸盐,消除黄磷的有毒污染,是一种安全有效方法。如水中的黄磷含量波动较大或存在高于0.1 mg/L的可能性,则采用加钙盐形成磷酸钙,再经过混凝过滤去除磷酸钙,以确保处理后的水质达到地表水Ⅱ类水标准和饮用水安全。
A trial study has been carried out on the drinking water contaminated by yellow phosphorus. The safe and feasible art is to oxidize the yellow phosphorus to phosphate with disinfectant as an oxidant combining with aeration for eliminating the toxicity of yellow phosphorus, while disinfecting the drinking water. If the concentration of the yellow phosphorus is higher than 0.1 mg/L or change dramatically, the calcium salt is needed to be added for transforming the yellow phosphorus to calcium phosphate, then eliminated by flocculation and filtration, to ensure that the treated water meet the national Ⅱ grade surface water quality standard and drinking water safety.
