【摘要】:人工濕地是處理受污染的公園景觀水體的一種新型的、行之有效的方法,能夠在去除水中的污染物的同時(shí),兼具觀賞性能和經(jīng)濟(jì)效益。北京園博湖人工濕地系統(tǒng)作為目前亞洲最大的潛流型人工濕地,是我國的濕地系統(tǒng)研究的重要研究對(duì)象,也是承載永定河豐臺(tái)段再生水水源凈化的重要工程項(xiàng)目。本研究以北京園博湖人工濕地系統(tǒng)作為研究對(duì)象,根據(jù)北京園博湖人工濕地系統(tǒng)在不同季節(jié)的情況,按照夏、冬兩季選擇合適的檢測時(shí)間做好水質(zhì)檢測工作。在潛流濕地的四個(gè)分區(qū)中,每個(gè)區(qū)分別選取三個(gè)單元濕地進(jìn)水閥井及與其相對(duì)應(yīng)的出水閥井作為監(jiān)測點(diǎn),并取其平均值作為監(jiān)測數(shù)據(jù)。對(duì)監(jiān)測指標(biāo)進(jìn)行處理后進(jìn)行數(shù)據(jù)分析、對(duì)比,結(jié)果表明,北京園博湖人工濕地系統(tǒng)對(duì)NH4-N、TP、COD、SS等指標(biāo)能起到一定的凈化效果,特別是對(duì)NH4-N的去除率最高可達(dá)到98.63%,平均總?cè)コ蔬_(dá)到73.17%。北京園博湖人工濕地系統(tǒng)的凈化出水對(duì)指標(biāo)的去除效率基本能夠滿足設(shè)計(jì)標(biāo)準(zhǔn),但各區(qū)的凈化效果存在差距、冬季和夏季的凈化效果相差較大。因此需建立健全北京園博湖人工濕地系統(tǒng)的管理機(jī)制、加強(qiáng)對(duì)水生植物的管理和維護(hù)、加大對(duì)游人的宣講力度以減小游人對(duì)北京園博湖人工濕地系統(tǒng)的影響。
[Abstract]:Constructed wetland is a new and effective method to treat the polluted park landscape water. It can remove the pollutants in the water at the same time as well as the ornamental performance and economic benefit.As the largest subsurface constructed wetland in Asia, Beijing Yuanbo Lake constructed wetland system is an important research object of wetland system in China, and also an important project to carry the reclaimed water source purification in Fengtai section of Yongding River.In this study, the Beijing Yuanbo Lake artificial wetland system is taken as the research object. According to the situation of Beijing Yuanbo Lake artificial wetland system in different seasons, according to the summer, winter and two seasons to select the appropriate detection time to do water quality detection.In each of the four subsurface wetland zones, three unit wetland intake valve wells and their corresponding outlet valve wells are selected as monitoring points, and their average values are taken as monitoring data.After processing the monitoring indexes, the data were analyzed and compared. The results showed that the constructed wetland system of Beijing Yuanbo Lake could purify NH _ 4-N ~ (2 +) TPCODSS and other indexes to a certain extent, especially the highest removal rate of NH4-N was 98.63 and the average total removal rate was 73.17%.The removal efficiency of the purified effluent from Beijing Yuanbo Lake constructed wetland system can basically meet the design standard, but there is a gap between the purification effect of each district and the difference between winter and summer.Therefore, it is necessary to establish and improve the management mechanism of Beijing Yuanbo Lake artificial wetland system, strengthen the management and maintenance of aquatic plants, and increase the propaganda to visitors in order to reduce the impact of visitors on the Beijing Yuanbo Lake constructed wetland system.
