摘　　要：以芜湖县陶辛镇污水处理厂入河排污口设置论证为例,针对受纳水域的特点,采用湖(库)均匀混合水质模型计算河流纳污能力并进行水质预测,分析综合衰减系数对水质预测结果的影响,在缺乏资料条件下,探讨确定综合衰减系数的途径与方法,以提高预测结果的可靠性。提出利用当地水体和沟渠组成的湿地对污水处理厂尾水进行降解的方案,经湿地降解后的水质满足受纳水体的水质管理目标要求;最后对入河排污口设置论证的要点和应注意的问题进行了探讨,可供入河排污口设置论证参考。Taking the argument on the set of sewage outlets of sewage treatment plants of Taoxin Town, Wuhu City as an example, and according to the characteristics of receiving water, we calculated pollutant carrying capacity of the river and predicted the water quality by using lake （reservoir） uniform mixture model. We analyzed the effect on water quality forecast results caused by synthesis attenuation coefficient. We discussed the methods to ascertain the comprehensive attenuation coefficient so as to make the result of water quality forecast more trustworthy under the condition of lacking data. We offered a plan of combining the local water and ditch as an artificial wetland to decompose the drainage of the sewage plant. Water decomposed by the artificial wetland could meet the water management standard for the receiving water. Finally, we discussed the key points of the argument on the set of sewage outlets and some problems that should be minded so as to provide references for the argument on the set of sewage outlets.
