农村生活污水论文：农村生活污水处理实用技术研究【中文摘要】随着农业经济的发展和城镇化的快速进程,农村生活污水已成为广大农村地区面源污染的主要来源,是造成农村水环境污染的重要原因之一。为探寻适合我国,尤其是四川省实际情况的农村生活污水处理实用技术,本研究依托于四川省住房和城乡建设厅科研项目课题,收集参阅了大量国内外现有的与农村生活污水处理有关的文献资料,并对四川省农村生活污水处理技术与工艺应用状况开展了实地调研,同时,根据四川省农村生活污水处理现状,在总结分析前人研究的基础上,设计了厌氧人工湿地组合工艺分散式处理农村生活污水的中试试验,系统研究了该组合工艺分散式处理农村生活污水的处理效果和运行特性。本论文将四川省划分为成都、攀西、川南、川东北、川西北高原5个农村生活污水治理区,在全面调研、分析与总结国内外,尤其是四川省农村生活污水处理技术与工艺的基础上,筛选和推荐：人工湿地与景观集成处理技术与工艺、WSHA生活污水厌氧达标处理技术与工艺、生物流化床与生物滤床复合式污水处理技术与工艺、一体化A/O(A2/O)设备处理技术与工艺、厌氧生物滤池氧化塘人工湿地复合处理技术与工艺、“双池”模式处理技术与工艺、厌氧沼气池处理技术与工艺、农家乐“厌氧人工湿地组合”共计8种适合于四川省不同分区、分类、分级的农村生活污水处理技术。本研究通过增设自调式沼气厌氧发酵罩和亲水弹性填料对传统厌氧人工湿地组合工艺进行了技术改进,中试试验结果表明：改进后的厌氧人工湿地组合工艺对农村生活污水的处理效果较好,系统对COD、NH3-N、TN和TP的平均去除率分别为87.44%、78.75%、73.58%和83.97%。该系统建设投资少、运行成本低廉,维护管理方便,适合农村地区生活污水处理的运用与推广。【英文摘要】Along with the development of agricultural economy and the rapid process of urbanization, rural domestic sewage has become the major source of non-point source pollution in vast rural areas and is one of the important reasons caused water pollution in rural areas. This study relies on the scientific research project of Office of Housing and Urban-Rural of Sichuan Province In order to explore rural domestic sewage treatment technology that suitable to China, especially in the actual situation of Sichuan Province, a large of existing literatures and information related to rural domestic sewage treatment were collected, and the application status of practical treatment method and technologies for rural domestic sewage of Sichuan Province were carried out. While,we designed the pilot test of decentralized wastewater treatment technology that combined with anaerobic and constructed wetland and investigated the operation characteristics and the treatment effect of the portfolio process at the conclusion of previous studies and based on the status of sewage treatment in rural areas of Sichuan Province.This thesis divided Sichuan Province into Chengdu, Panzhihua-Xichang, South of Sichuan, Northeast of Sichuan and Northwestern of Sichuan five rural sewage treatment areas. Basted on a comprehensive research, analysis and summary of domestic and foreign, especially in rural domestic sewage treatment technology and process of Sichuan Province, constructed wetlands and landscape integration processing technology and process, anaerobic filter and oxidation pond and wetland complex processing technique and technology, WSHA anaerobic treatment technology and process, integration of A/O (A2/O) device processing and technology, biological fluidized bed combined with the biological filter bed sewage treatment technology and process, “two-cell” mode processing technology and processes, anaerobic digesters processing technique and technology, farm music “tired of Oxygen and Wetland portfolio “ a total of 8 rural domestic sewage treatment technologies that for different areas in Sichuan Province were screened and recommended.This study improved the conventional technology that combined with anaerobic and constructed wetland by adding a red bogs gas mask and hydrophilic elastic filler. The results of pilot test showed that the improved wastewater treatment combined with anaerobicand constructed wetland is very effective in treating rural domestic wastewater,the system could remove 87.44%,78.75%,73.58% and 83.97% of COD, NH3-N, TN and TP respectively. This system is very effective in treating rural domestic wastewater, and it is also material/energy-saving compared with central technical systems, thus, worth popularization and application.【关键词】农村生活污水 工艺推荐 分散处理 厌氧 人工湿地 四川省【英文关键词】Rural domestic sewage Recommended process decentralized treatment anaerobic constructed wetland Sichuan Province【目录】农村生活污水处理实用技术研究摘要6-7Abstract7-8第1章 绪论11-221.1 研究背景11-121.2 农村生活污水处理技术概况12-151.2.1 农村生活污水处理模式12-131.2.2 国内外农村生活污水处理技术研究现状13-151.3 厌氧生物处理概述15-171.3.1 厌氧生物处理基本原理15-171.3.2 厌氧生物处理技术的特点171.4 人工湿地污水处理技术概述17-201.4.1 人工湿地的分类17-181.4.2 人工湿地系统的构造181.4.3 人工湿地的净化机理18-201.4.4 人工湿地的特点201.5 研究的目的和意义20-211.6 课题研究内容、研究方法及技术路线21-221.6.1 研究内容211.6.2 研究方法211.6.3 技术路线21-22第2章 农村生活污水处理实用技术调研及工艺推荐22-442.1 四川省农村生活污水治理地区的划分22-232.2 问卷调查结果与分析23-252.3 实地调研结果与分析25-282.4 农村生活污水处理实用技术推荐28-402.4.1 人工湿地与景观集成处理技术与工艺29-312.4.2 WSHA生活污水厌氧达标处理技术与工艺31-322.4.3 生物流化床与生物滤床复合式污水处理技术与工艺32-342.4.4 一体化A/O(A2/O)设备处理技术与工艺34-352.4.5 厌氧生物滤池氧化塘人工湿地复合处理技术与工艺35-362.4.6 “双池”模式处理技术与工艺36-382.4.7 沼气池处理技术与工艺38-392.4.8 农家乐”厌氧人工湿地组合”污水处理技术与工艺39-402.5 其他推荐方式40-432.5.1 按集中和分散处理分类进行推荐40-412.5.2 按四川省农村生活污水治理分区推荐412.5.3 按日污水处理量推荐41-422.5.4 按逐步推进模式推荐42-432.6 本章小结43-44第3章 厌氧人工湿地组合工艺处理农村生活污水研究44-
