【摘要】：什剎海水域由西海、后海、前海三個(gè)水域組成。水域面積為146.7公頃(不含北海、中海、南海),隸屬長河水系。隨著人口增長,經(jīng)濟(jì)建設(shè)和城市建設(shè)的飛速發(fā)展,水域上游及什剎海河湖沿岸違章建筑增多,未經(jīng)治理的生活污水及工業(yè)廢水大量無組織排入湖中,使之水體富營養(yǎng)化程度日趨嚴(yán)重,而上游的新鮮水源又不充足,作為重要的旅游景區(qū),沿岸周邊的零散污染源不好控制等多種因素造成水體水質(zhì)下降,必須制定合理的改善措施。本文主要針對(duì)什剎海水體的污染情況,分別對(duì)什剎海后海水質(zhì)、底質(zhì)及生物特征進(jìn)行調(diào)查監(jiān)測(cè)；對(duì)什剎海后海水體富營養(yǎng)化發(fā)展原因進(jìn)行了調(diào)查與分析；開展了對(duì)什剎海后海水環(huán)境污染治理技術(shù)的研究；分三個(gè)階段建立了三個(gè)專項(xiàng)治理工程實(shí)驗(yàn)；并對(duì)什剎海后海水域管理措施提出了建議。通過抑藻除藻、底質(zhì)修復(fù)和微生物調(diào)控三個(gè)階段的綜合治理研究與示范,什剎海水質(zhì)的各項(xiàng)監(jiān)測(cè)指標(biāo)基本達(dá)到了《地表水環(huán)境質(zhì)量標(biāo)準(zhǔn)》(GHZB1-1999)中的三類水標(biāo)準(zhǔn),水質(zhì)整體情況有了明顯的改善,對(duì)美化什剎海環(huán)境改善景觀水質(zhì)起到了較好的效果,對(duì)社會(huì)起到了良好的生態(tài)效益。什剎海風(fēng)景區(qū)已經(jīng)存在和建設(shè)數(shù)百年,在其周邊已形成很大規(guī)模的風(fēng)景景觀。因此,什剎海的水質(zhì)治理、保護(hù)和生態(tài)建設(shè),對(duì)于整個(gè)北京的城市生態(tài)化建設(shè)和發(fā)展,有著重要的指導(dǎo)作用和推廣意義。
[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.
