摘　　要：通过对温度与原水水质、出水水质和各工艺段处理效果的相关性分析,研究结果如下:季节变化对原水中的CODMn影响比较大,而对原水中的氨氮和亚氮浓度影响不大;对出水中的CODMn、氨氮和亚氮浓度都有影响;生物预处理设施、絮凝沉淀池、V型砂滤池、一级臭氧接触池和二级臭氧接触池的CODMn去除率基本不受季节变化的影响,季节变化只影响一、二级生物活性炭池CODMn的去除率;季节变化影响生物预处理设施、V型砂滤池对氨氮去除率,而对絮凝沉淀池的氨氮去除率基本没有影响。Based on correlation analysis of the temperature,the raw water quality,the effluence water quality,and treatment effect,research results were as follows：seasonal changes had great impacts on the CODMn concentration in raw water,but slight on the NH3—N,NO-2—N concentration,and had affected significantly on the CODMn,NH3—N,NO-2—N concentration in effluence water; the removal efficiency of the CODMn in biological pre-treatment,flocculation sedimentation tank,V sand filter,first and secondary ozone contact tanks was not influenced by seasonal changes; seasonal changes affected only the removal efficiency of CODMn,NO-2—N concentration in first and secondary biological activated carbon filters. Seasonal changes affected the removal efficiency of NH3—N in biological pre-treatment,V sand filter,while the removal efficiency of NH3—N in flocculation sedimentation tank did not be affected.
