次氯酸钠应急处理突发锰污染厂试研究

Plant pilot study on sodium hypochlorite emergency treatment of sudden manganese pollution

饮用水除锰问题一直备受关注。依托工程实际案例,对水厂中的常备药剂次氯酸钠应急处理突发锰污染的可行性进行了研究,分析了次氯酸钠的投加位点、投加量以及混凝剂的投加对除锰效果的影响。基于厂试实验结果,提出了合理的次氯酸钠应急处理突发锰污染方案,为相关水厂处理类似问题提供了参考。

The problem of manganese removal from drinking water has been of great concern. In this paper, the feasibility of emergency treatment of sudden manganese contamination with sodium hypochlorite, a commonly used agent in water plants, is studied based on actual cases. The effects of the dosing site, dosing amount and coagulant dosing of sodium hypochlorite on the effect of manganese removal are analyzed. Based on the results of the plant trial, a reasonable emergency treatment plan of sodium hypochlorite for sudden manganese contamination was proposed, which provides a reference for the treatment of similar problems in related water plants.
