【摘要】：近幾年旬陽縣發(fā)展迅速,建設(shè)用地?cái)U(kuò)大較快,城區(qū)生活污水與工業(yè)廢水的這種分散的排放方式,已嚴(yán)重污染了旬河的水環(huán)境,特別是枯水期,河水流量少時(shí)感官極差,已引起民眾強(qiáng)烈反響。隨著旬陽縣工農(nóng)業(yè)生產(chǎn)的飛速發(fā)展,居民生活水平的不斷提高,污、廢水的量和污染物的濃度將隨之增加,污染問題也將越來越嚴(yán)重。旬陽縣城現(xiàn)狀無城市污水處理設(shè)施,僅部分生活污水經(jīng)化糞池處理,工業(yè)廢水治理率和達(dá)標(biāo)率均很低,城市生活污水和工業(yè)廢水的排放,已造成旬河的水質(zhì)污染。污水處理工程是城市基礎(chǔ)設(shè)施不可缺少的部分,它的建設(shè)將使日漸被污染的旬河水質(zhì)得到完全的改善,將為旬陽縣人民帶來一個(gè)健康的生活環(huán)境。本文針對(duì)該地區(qū)的具體問題,調(diào)查相關(guān)資料,提出排水系統(tǒng)以及污水處理系統(tǒng)的優(yōu)化方案。通過本課題的研究,在對(duì)旬陽縣進(jìn)行排水系統(tǒng)和污水處理系統(tǒng)進(jìn)行規(guī)劃設(shè)計(jì),尤其是在選擇污水處理工藝時(shí),提供了一個(gè)具有實(shí)際意義的參考。本文研究的主要內(nèi)容:1、經(jīng)過查閱資料和現(xiàn)場(chǎng)調(diào)研,了解旬陽縣的自然概況、水質(zhì)現(xiàn)狀,分析該地區(qū)的排水系統(tǒng)及污水處理系統(tǒng)現(xiàn)狀,提出這些地區(qū)在這方面存在的問題。2、排水系統(tǒng)主要是針對(duì)污水系統(tǒng)。對(duì)于這個(gè)系統(tǒng)的優(yōu)化,主要是從設(shè)計(jì)參數(shù)的選擇、排水體制選擇、管網(wǎng)平面布置等方面出發(fā),通過對(duì)比分析,提出排水系統(tǒng)的設(shè)計(jì)優(yōu)化技術(shù)。3、通過閱讀參考文獻(xiàn),提出適于縣城污水處理的工藝方案,結(jié)合陜南地區(qū)縣城的具體情況,通過方案的對(duì)比優(yōu)選,確定該地區(qū)的污水處理系統(tǒng)方案。4、將所提的排水系統(tǒng)和污水處理技術(shù)優(yōu)化的理論和方法運(yùn)用到陜南地區(qū)的某一代表性縣城——旬陽縣,結(jié)合旬陽縣排水專項(xiàng)規(guī)劃和現(xiàn)場(chǎng)調(diào)研資料,對(duì)旬陽縣的排水系統(tǒng)和污水處理系統(tǒng)進(jìn)行規(guī)劃設(shè)計(jì)。
[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.
