摘 要:重金属镍对水体的污染时有发生,实验通过模拟北江流域水源水受到重金属镍污染的情况,利用强化混凝的方法投加氢氧化钠、高锰酸钾、活性炭、聚合氯化铝等试剂对重金属镍的去除进行烧杯试验。通过调节原水的p H值在9.0左右,高锰酸钾与活性炭的投加量分别调节至2.2 mg/L与40 mg/L,经过混凝-沉淀之后的水样重金属镍的含量低于国标限值,去除率最高,达到89%。The surface water is polluted by heavy metals of nickel occasionally. The experiment simulated the situation that the Beijiang surface water was polluted by heavy metals of nickel. Beaker experiment was proced to do in the laboratory,by using the enhanced coagulation method to add sodium hydroxide,potassium permanganate,activated carbon and polymeric aluminum chloride for the removal of heavy metals. The results showed that when p H value of the raw water was adjusted to 9. 0,the potassium permanganate and activated carbon dosage were adjusted to 2. 2 mg / L and40 mg / L,respectively,the nickel content of the water after precipitation was lower than the national standard limit,which had the highest removal rate 89%.
