【摘要】：什刹海水域由西海、后海、前海三个水域组成。水域面积为146.7公顷(不含北海、中海、南海),隶属长河水系。随着人口增长,经济建设和城市建设的飞速发展,水域上游及什刹海河湖沿岸违章建筑增多,未经治理的生活污水及工业废水大量无组织排入湖中,使之水体富营养化程度日趋严重,而上游的新鲜水源又不充足,作为重要的旅游景区,沿岸周边的零散污染源不好控制等多种因素造成水体水质下降,必须制定合理的改善措施。本文主要针对什刹海水体的污染情况,分别对什刹海后海水质、底质及生物特征进行调查监测；对什刹海后海水体富营养化发展原因进行了调查与分析；开展了对什刹海后海水环境污染治理技术的研究；分三个阶段建立了三个专项治理工程实验；并对什刹海后海水域管理措施提出了建议。通过抑藻除藻、底质修复和微生物调控三个阶段的综合治理研究与示范,什刹海水质的各项监测指标基本达到了《地表水环境质量标准》(GHZB1-1999)中的三类水标准,水质整体情况有了明显的改善,对美化什刹海环境改善景观水质起到了较好的效果,对社会起到了良好的生态效益。什刹海风景区已经存在和建设数百年,在其周边已形成很大规模的风景景观。因此,什刹海的水质治理、保护和生态建设,对于整个北京的城市生态化建设和发展,有着重要的指导作用和推广意义。
[Abstract]:Shichahai waters by the West Sea, Houhai, Qianhai three waters. Water area of 146.7 hectares (excluding the North Sea, China Sea, South China Sea, belong to the Yangtze River system. With the growth of population, the rapid development of economic construction and urban construction, the number of illegal buildings in the upper reaches of the water area and along the Shichahai River and lake has increased, and untreated domestic sewage and industrial waste water have been discharged into the lake in a large amount without organization. The eutrophication degree of the water body is becoming more and more serious, while the fresh water source in the upper reaches is not sufficient. As an important tourist spot, the scattered pollution sources around the coast are not easy to control and other factors cause the water quality to decline. Reasonable improvement measures must be made. In this paper, the water quality, sediment and biological characteristics of Shichahou Sea were investigated and monitored, and the reasons for eutrophication development of Shichahai Sea were investigated and analyzed. In this paper, the study of water pollution control technology in Shichahai Sea was carried out, three special engineering experiments were set up in three stages, and some suggestions were put forward for the management measures of Shichahai Sea area. Through the comprehensive control and demonstration of algae inhibition, sediment remediation and microbial regulation, the monitoring indexes of water quality in Shichahai have basically reached the three kinds of water standards of "Surface Water Environmental quality Standard" (GHZB1-1999). The overall situation of water quality has been obviously improved, which has played a better role in beautifying the environment of Shichahai and improving the landscape water quality, and has played a good ecological benefit to the society. Shichahai Scenic spot has existed and built for hundreds of years, and has formed a very large scale landscape around it. Therefore, the water quality control, protection and ecological construction of Shichahai are of great significance to the ecological construction and development of the whole city in Beijing.
