摘　　要：针对城市给排水产生的污水,一般采用絮凝沉淀法进行降解处理,但在该过程中往往难以有效去除有机物,导致治理后水体的化学需氧量(COD)含量仍较高,故文章提出一种基于臭氧技术的给排水污水治理方法。结合给排水污水排放特征与行政管理需求,将整个治理区域划分为多个治理控制单元并实时监测污水流量。根据生成的污水治理模式,建立臭氧消毒数学模型,并计算出相应的治理参数。依据最小费用原则,实现了给排水污水的高效治理。实验结果表明,应用所提方法后,出水平均COD含量和NH_(3)-N含量分别为14 mg/L^(-1)和3 mg/L^(-1),更好地满足了污水治理的要求。In view of the sewage produced by urban water supply and drainage,flocculation precipitation method is generally used for degradation treatment,but it is often difficult to effectively remove organic matter in this process,resulting in high chemical oxygen demand(COD)content in treated water bodies.Therefore,this paper proposes a treatment method for water supply and drainage wastewater based on ozone technology.Combined with the characteristics of sewage discharge and administrative management requirements,the whole treatment area is divided into multiple control units and real-time monitoring of sewage flow.According to the generated sewage treatment model,the mathematical model of ozone disinfection is established,and the corresponding treatment parameters are calculated.According to the principle of minimum cost,the efficient treatment of water supply and drainage is realized.The experimental results show that after the application of the proposed method,the average COD content and NH_(3)-N content of the effluent are 14 mg/L^(-1)and 3 mg/L^(-1),respectively,which better meets the requirements of sewage treatment.
