摘要
污水处理是指对污染的废水进行净化,使其达到一定的排放标准。按来源污水可分为工业废水、生活废水两大类,污水处理中生物处理、物理处理、化学处理是常见处理方法。近年来随着科学技术的不断进步,脉冲电晕、光催化、超声波等技术的应用越来越广泛,膜生物反应器、超滤膜等处理技术更是应运而生。基于此,文章首先对城市生活污水处理技术进行了介绍,包括生物处理法、物理处理法及脉冲电晕处理技术、光催化处理技术等,然后对城市污水处理实际运行难题进行了分析并提出大力发展污水处理新技术、加大污水处理的资金扶持等解决措施,以期为城市污水处理工程人员提供参考。
Sewage treatment refers to the purification of polluted wastewater to meet certain discharge standards.According to the source of sewage,it can be divided into industrial wastewater and domestic wastewater.Biological treatment,physical treatment and chemical treatment are common treatment methods in sewage treatment.In recent years,with the continuous progress of science and technology,the application of pulse corona,photocatalysis,ultrasonic and other technologies has become more and more extensive.Membrane bioreactor,ultrafiltration membrane and other treatment technologies have emerged as the times require.Based on this,this paper first introduces the urban domestic sewage treatment technology,including biological treatment method,physical treatment method,pulse corona treatment technology,photocatalytic treatment technology,etc.,and then analyzes the practical operation problems of urban sewage treatment and puts forward solutions such as vigorously developing new sewage treatment technology and increasing financial support for sewage treatment,in order to provide reference for urban sewage treatment engineers.
