摘　　要：夏季西北地区暴雨过后附近高浊度山洪水流入黄河,导致黄河水受到轻微污染呈现微污染水质特性。为了进一步提高水中有机物、氨氮、浊度、UV254的去除率,采用响应面软件中的Box-Behnken中心组合设计方法,考察了混凝剂投加量、搅拌时间、pH等各因素交互作用对混凝沉淀法去除水中浊度、高锰酸盐指数、氨氮、UV254污染物的影响。研究建立了相关的二次多项式数学模型,以浊度、高锰酸盐指数、氨氮及UV254去除率作为响应值,确定出最佳的混凝沉降反应参数。In summer, high turbidity mountain flood water of heavy rainfall flows into the Yellow River in Northwest China, which results to pollution of the Yellow River. In order to improve the removal rate of organic matter, ammonia nitrogen, turbidity and UV254 in water, Box-Behnken central combination design method of response surface software is used to investigate the influence of the interaction of coagulant dosage, stirring time, pH value and other factors on the removal of turbidity, permanganate index, ammonia nitrogen and UV254 pollutants in water by coagulation precipitation. The relevant quadratic polynomial mathematical model is established and the turbidity, permanganate index, ammonia nitrogen and UV254 removal rate are used as the response values to determine the optimal coagulation sedimentation reaction parameters.
