XunYang County Sewage Treatment Technology And Drainage System Design Optimization

XunYang city has developed rapidly in recent years, rapid expansion of construction land, urban sewage and industrial wastewater discharge this decentralized approach, has been seriously polluted the late River water environment, especially in the dry season, the river flow is low sensory poor has aroused strong repercussions people. With the rapid development of industrial and agricultural production Xunyang,continuous improvement of living standards, the concentration of sewage wastewater and pollutants increases, the pollution problem will become increasingly serious.XunYang county status quo no municipal sewage treatment facilities. Only part of the sewage by septic tank treatment, industrial wastewater treatment rate and compliance rate is very low, emission urban sewage and industrial wastewater, water pollution has caused late River. Urban sewage treatment works is an indispensable part of the infrastructure that will enable the construction of late increasingly polluted river water quality has been completely improved, the people will bring a quality Xunyang, healthy living environment.In this text, the specific problems of the region, the survey information, the optimization scheme proposed drainage system and wastewater treatment system. By studying this subject, at the time of Xunyang drainage systems and sewage treatment systems planning and design, particularly in the choice of the sewage treatment process,provides a meaningful reference.The main contents of this text:1.By investigating and literature reviewing on XunYang city,know the general situation of nature and the present situation of water quality in these areas, analyze the present situation of drainage system and sewage system of these areas,raise this sideissue existing in these areas;2.The drainage system includes sewage system.For the design of this system optimization, mainly from the drainage system selection, pipe network layout, and other design parameters to select the standpoint of comparative analysis, the design of the drainage system proposed optimization techniques.3.Though literature review,put forward process schemes which are fit for sewage treatment of city.Combining with the specific conditions of city in southern Shanxi,establish the sewage treatment plan of this area.4.Using the proposing theory and methods about the drainage system and sewage treatment to one representative city of southern Shanxi---XunYang city, combining with specialized planning on drainage of XunYang and research data,design the drainage system and sewage system of XunYang.
