【摘要】：近几年旬阳县发展迅速,建设用地扩大较快,城区生活污水与工业废水的这种分散的排放方式,已严重污染了旬河的水环境,特别是枯水期,河水流量少时感官极差,已引起民众强烈反响。随着旬阳县工农业生产的飞速发展,居民生活水平的不断提高,污、废水的量和污染物的浓度将随之增加,污染问题也将越来越严重。旬阳县城现状无城市污水处理设施,仅部分生活污水经化粪池处理,工业废水治理率和达标率均很低,城市生活污水和工业废水的排放,已造成旬河的水质污染。污水处理工程是城市基础设施不可缺少的部分,它的建设将使日渐被污染的旬河水质得到完全的改善,将为旬阳县人民带来一个健康的生活环境。本文针对该地区的具体问题,调查相关资料,提出排水系统以及污水处理系统的优化方案。通过本课题的研究,在对旬阳县进行排水系统和污水处理系统进行规划设计,尤其是在选择污水处理工艺时,提供了一个具有实际意义的参考。本文研究的主要内容:1、经过查阅资料和现场调研,了解旬阳县的自然概况、水质现状,分析该地区的排水系统及污水处理系统现状,提出这些地区在这方面存在的问题。2、排水系统主要是针对污水系统。对于这个系统的优化,主要是从设计参数的选择、排水体制选择、管网平面布置等方面出发,通过对比分析,提出排水系统的设计优化技术。3、通过阅读参考文献,提出适于县城污水处理的工艺方案,结合陕南地区县城的具体情况,通过方案的对比优选,确定该地区的污水处理系统方案。4、将所提的排水系统和污水处理技术优化的理论和方法运用到陕南地区的某一代表性县城——旬阳县,结合旬阳县排水专项规划和现场调研资料,对旬阳县的排水系统和污水处理系统进行规划设计。
[Abstract]:Xunyang County has developed rapidly in recent years, and the construction land has expanded rapidly. This decentralized discharge mode of municipal domestic sewage and industrial wastewater has seriously polluted the water environment of Xunhe River, especially during the dry season, when the river flow is small, the senses are extremely poor. With the rapid development of industrial and agricultural production in Xunyang County, the living standards of the residents are constantly improving, and the amount of waste water and the concentration of pollutants will increase along with it. The pollution problem will also become more and more serious. Xunyang County has no municipal sewage treatment facilities, only some domestic sewage is treated by septic tanks, the treatment rate and the standard rate of industrial wastewater are very low, and municipal domestic sewage and industrial wastewater are discharged. The water quality of Xunhe River has been polluted. The sewage treatment project is an indispensable part of the urban infrastructure, and its construction will completely improve the water quality of the increasingly polluted Xunhe River. It will bring a healthy living environment for the people of Xunyang County. In this paper, according to the specific problems in this area, we investigate the relevant information, and put forward the optimized scheme of drainage system and sewage treatment system. In the planning and design of drainage system and sewage treatment system in Xunyang County, especially in the selection of sewage treatment process, a reference of practical significance is provided. To understand the natural situation and water quality of Xunyang County, analyze the present situation of drainage system and sewage treatment system in this area, and put forward the problems in these areas. The drainage system is mainly aimed at sewerage system. Based on the selection of design parameters, the selection of drainage system, the layout of pipe network and so on, through comparison and analysis, the paper puts forward the design optimization technology of drainage system .3. by reading the references, it puts forward the technological scheme suitable for sewage treatment in county towns. According to the specific situation of the county towns in southern Shaanxi, through the comparative selection of programs, The sewage treatment system scheme of this area is determined. The theory and method of drainage system and sewage treatment technology optimization are applied to Xunyang County, a representative county town in southern Shaanxi, and combined with special drainage planning and field investigation data in Xunyang County. The drainage system and sewage treatment system in Xunyang County were planned and designed.
