城市污水处理技术研究

随着城市化的发展,城镇生活污水和工业废水排放逐年增大,且成分复杂,是导致水体恶化的重要污染源.针对生活污水的核心是生化部分,现有城市污水处理厂主要采用普通活性污泥法、氧化沟法、厌氧-缺氧-好氧法(A2/O)、曝气生物滤池(BAF)、序批式活性污泥法(SBR)和膜生物反应器(MBR),工业废水多为高浓度有机废水,以厌氧生物处理法和膜分离技术为主.介绍了城市主要水处理技术的优势劣势,展望了水处理技术的发展前景,为城镇水处理技术指出了发展方向.

Research on Waste Water Treatment Technology

Along with the development of the urbanization,the amount of domestic waste water and high concentrated organic waste water has been increased recent years.The composition of wastewater is complex, which is an important source of pollution.Biochemical part is the core of water treatment, and nowadays the existing city sewage treatment plant using conventional activated sludge process, Continuous Loop Reator, A2/O,BAF,SBR and MBR.Most of the industrial wastewater is high concentrated organic wastewater,and the main treatment method is anaerobic biological treatment and membrane separation technology.The article introduces the advantages and disadvantages of the main water treatment technology in the urban area, and also looks forward the prospect and points out the direction of development of urban wastewater treatmenttechnology.
