摘　　要：以某企业水厂进水为对象,提出应用混凝-沉淀与混凝-气浮水处理工艺,并对比研究两种工艺对浊度和氨氮水质指标的去除,得出结论,当沉淀与气浮工艺出水浊度均是1NTU左右时,混凝气浮工艺相比于混凝沉淀工艺的PAFC加入量少约40%;而当加入相同的混凝剂投药量,混凝气浮工艺相比于混凝沉淀工艺对氨氮去除率也要略高。因此,对于低温低浊水质的水处理厂,可优先考虑采用气浮工艺进行水质处理。Taking the influent from a water plant of an enterprise as the object,the application of coagulation sedimentation and coagulation air flotation water treatment processes is proposed,and the removal of turbidity and ammonia nitrogen water quality indicators by the two processes is compared.It is concluded that when the effluent turbidity of sedimentation and air flotation processes is about 1NTU,the PAFC addition of coagulation air flotation process is about 40%less than that of coagulation sedimentation process.When the same dosage of coagulant is added,the removal rate of ammonia nitrogen by coagulation air flotation process is slightly higher than that by coagulation sedimentation process.Therefore,for water treatment plants with low temperature and low turbidity water quality,priority can be given to the use of air flotation process for water quality treatment.
