中文摘要: 以聚合氯化铝为混凝剂,通过烧杯试验研究了单独高锰酸钾、单独粉末活性炭,以及高锰酸钾与粉末活性炭二者联用等方法对混凝去除微污染水源中污染物的性能.研究结果表明,高锰酸钾与粉末活性炭联用对水中有机物和浊度的去除有一定的强化作用,在相同混凝剂用量时,UV254和浊度的去除率可提高7%~10%;在达到相近的有机物去除率时,可显著降低混凝剂的投加量.
Abstract:In order to solve the serious issue of raw water pollution, the removal rate with three methods, such as dosing potassium permanganate solely, dosing powdered activated carbon solely and potassium permanganate combined with powdered activated carbon are investigated by using Jar test. The results show that the combined process of Potassium Permanganate and powdered activated carbon adsorption is effective for enhancing treatment of micro-polluted raw water. The removal rate of UV254 and turbidity can be improved by 7%~10% compared with the case when coagulants are used alone at the same coagulants dose. It also could decrease the optimum dose of coagulants while keeping the similar organic matters removal rate.
