【摘要】 通过在四种受污染水样情况下的试验,对流动电流响应混凝剂投量的变化规律进行了研究。发现流动电流与投药量的相关性仍然存在,但是有机污染物的存在使流动电流的响应强度降低,降低程度与污染物的种类、浓度等因素有关。一般在CODMn不超过10mg/L的情况下,污染物的影响程度较小,将流动电流混凝投药控制技术应用于此条件下的受污染水源水是可能的。更多还原

【Abstract】 The experiment made with four kinds of polluted water in a semi-batch reactor indicated that the pollutants in water decreased the precision of streaming current control system,and the regu-larity of streaming current was related to the kind and concentration of pollutant.Moreover,for a giv-en type of pollutant water,the regularity of streaming current was strongly affected by the composition of the kind of water.However,the relationship between SC and coagulant dosage still existed under the experimental condition.And the effect was not noticeable when COD Mn of the water resource didn’t exceed10mg /L,so the streaming current control method for coagulant dosage could be used in the water resource polluted by organic-pollutant.更多还原
