Description

一种城市河道水环境治理方法A method of urban river water environment management

技术领域technical field

本发明涉及一种城市河道水环境治理方法,属于水环境治理与水生态修复领域。The invention relates to an urban river water environment treatment method, which belongs to the field of water environment treatment and water ecological restoration.

背景技术Background technique

随着我国城市化的推进,河道水环境治理任务日益繁重。城市河道主要污染物来自生活污水和初期雨水。一方面,城市排水管网中污水管和雨水管的“错接混接、互通互渗”等现象造成了大量生活污水入河;另一方面,大量面源污染物在雨水冲刷下通过城市雨水管道或者漫流进入河道。这两类污染源分布范围广、污染量大,对其进行收集处理的难度高,严重影响了城市河道水环境的质量。此外,城市河道普遍存在硬质驳岸,阻断了水体与土壤的物质生物交换,损害了水陆过渡区的水生态。With the advancement of urbanization in my country, the task of river water environment management is becoming increasingly arduous. The main pollutants in urban rivers come from domestic sewage and initial rainwater. On the one hand, the phenomenon of "misconnection and inter-penetration" between sewage pipes and rainwater pipes in the urban drainage network has caused a large amount of domestic sewage to enter the river; Or flood into the river. These two types of pollution sources have a wide distribution range and a large amount of pollution, and it is difficult to collect and process them, which seriously affects the quality of urban river water environment. In addition, hard revetments commonly exist in urban river courses, which block the biological exchange of water and soil, and damage the water ecology in the water-land transition zone.

目前,城市河道水环境治理方法主要包括以下三类:第一类是降低污染物的增量,主要通过控制外源性污染物进入河道来实现;第二类是降低污染物的存量,比如清除河道淤泥或打捞蓝藻等方法;第三类是增加受纳水体的环境容量,比如设置生态浮岛或加入微生物菌剂等措施以提升水体的自净能力。其中,对入河污染物进行收集处理是城市河道水环境治理的治本之策,然而目前我国雨污分流体制不完善,污水管网结构性缺陷和功能性缺陷十分普遍,对于初雨污染缺乏针对性的治理措施,因此很难有效地控制外源性入河污染物。河道清淤工程涉及大规模干河作业,施工难度相对较大,而且施工过程中水土压力的释放将对岸墙造成安全隐患,老旧驳岸坍塌事故屡有发生,清出的淤泥处置成本很高。最后,常用于净化水质的生态浮岛虽然能够改善河道的自然生态环境,但其制作施工周期长,管理养护成本高,难以过冬,难抗风浪,这些问题和不足都制约了该技术的推广。At present, the treatment methods of urban river water environment mainly include the following three categories: the first category is to reduce the increment of pollutants, which is mainly achieved by controlling the entry of exogenous pollutants into the river; the second category is to reduce the stock of pollutants, such as removing pollutants. The third category is to increase the environmental capacity of the receiving water body, such as setting up ecological floating islands or adding microbial agents to improve the self-purification capacity of the water body. Among them, the collection and treatment of pollutants entering rivers is a fundamental solution for urban river water environmental governance. However, at present, the separation system of rain and sewage in my country is not perfect, and the structural and functional defects of sewage pipe network are very common. Therefore, it is difficult to effectively control exogenous pollutants entering the river. The river dredging project involves large-scale dry river operations, and the construction is relatively difficult. Moreover, the release of water and soil pressure during the construction process will cause safety hazards to the bank wall. Collapse accidents of old revetments frequently occur, and the disposal cost of the cleared silt is high. Finally, although the ecological floating islands commonly used to purify water quality can improve the natural ecological environment of the river, its production and construction period is long, the management and maintenance costs are high, it is difficult to survive winter, and it is difficult to resist wind and waves. These problems and deficiencies restrict the promotion of this technology.

发明内容SUMMARY OF THE INVENTION

本发明针对在现有城市河道水环境治理技术方面存在的不足,提供一种施工方便,运维成本低,能有效对入河污染物进行收集处理的城市河道多功能水环境治理方法。Aiming at the deficiencies in the existing urban river water environment treatment technology, the invention provides a multifunctional urban river water environment treatment method with convenient construction, low operation and maintenance cost, and effective collection and treatment of pollutants entering the river.

In the river channel, the water body in the river channel is separated by a water barrier and soil retaining piles along the river bank retaining wall, a near-shore zone is set, and an ecological shallow water is set in the near-shore zone. The bottom of the ecological shallow water area and the local deep water area are filled with river silt and then covered with a biological filler layer, aquatic plants are planted on the biological filler layer in the ecological shallow water area, and the water depth in the shallow water area is controlled at 20-30cm; The local deep water area is set below the river discharge outlet, and the bottom elevation of the local deep water area is lower than the river discharge outlet; sewage lifting pumps are set at fixed points in the nearshore zone to collect all kinds of sewage in the nearshore zone and discharge into the municipal sewage system or into a separate water treatment plant.

A preferred solution is that the water blocking wall is an acrylic plate, which is fixed on the inner side of the soil retaining pile, and the top height of the water blocking wall is 10-20 cm higher than the normal water level of the river; The soil piles are wood piles and concrete piles, which are fixed under the riverbed. The following structure can also be used: the soil-retaining pile and the water-retaining wall are integrated into one structure, and the material is plastic-steel Larsen sheet piles, which are fixed under the river bed, and the top height is 10-20 cm higher than the normal water level of the river.

本发明提供的一种城市河道水环境治理方法,其生态浅水区与局部深水区的淤泥层通过斜坡状过渡区相连。The invention provides an urban river water environment treatment method, wherein the ecological shallow water area and the silt layer in the local deep water area are connected through a slope-shaped transition area.

本发明的原理是:在河道内沿河岸挡墙设置近岸带,由隔水墙和保土桩从河道内划分出来,与河道内水体不连通,可收集各类入河污染物,具有截流干管收集入河污染物的全部功能;近岸带内分为生态浅水区和局部深水区,生态浅水区内填充河道淤泥和生物填料,一方面可以解决部分河道淤泥的处置问题,另一方面生物填料层上种植水生植物,可以实现生态浮岛净化水质和美化景观等全部功能;局部深水区设置在入河排口处,填充河道淤泥,铺盖生物填料,高度以不影响排口出流为限;在近岸带内定点设置污水提升泵,集中收集近岸带内的各类污水,排入市政污水系统或进入独立水处理装置。旱天时,入河污染物以生活污水为主,通过雨污混流、雨污合流的排水管流入河道的近岸带,由近岸带的生物填料和水生植物初步净化,再由提升泵集中收集排入市政污水系统或进入独立水处理装置进一步净化后入河。降水初期,雨水冲刷道路后形成的面源污染物通过径流进入河道内的近岸带,由近岸带的生物填料和水生植物初步净化,再由提升泵集中收集排入市政污水系统或进入独立水处理装置进一步净化;降水中后期,雨水径流中污染物浓度已较低,进入近岸带后,超量径流溢流过隔水墙,排入河道,不会影响城市排水防涝。由于近岸带高程不高于河道常水位,不会影响河网调蓄雨涝的功能。The principle of the invention is as follows: a near-shore zone is set along the river bank retaining wall in the river channel, which is divided from the river channel by the water-retaining wall and the soil retaining pile, and is not connected with the water body in the river channel.

Set up sewage lifting pumps at fixed points in the near-shore zone to collect all kinds of sewage in the near-shore zone and discharge it into the municipal sewage system or into an independent water treatment device. In dry days, the pollutants entering the river are mainly domestic sewage, which flows into the near-shore zone of the river through the drainage pipes of mixed flow of rain and sewage and confluence of rain and sewage. Discharge into the municipal sewage system or into the independent water treatment device for further purification and then into the river. In the early stage of precipitation, the non-point source pollutants formed by rainwater scouring the road enter the nearshore zone in the river channel through runoff, and are initially purified by the biological fillers and aquatic plants in the nearshore zone, and then collected and discharged into the municipal sewage system or into the independent sewage system by the lift pump. The water treatment device is further purified; in the middle and late stages of precipitation, the concentration of pollutants in the rainwater runoff is already low. After entering the nearshore zone, the excess runoff overflows through the partition wall and discharges into the river, which will not affect urban drainage and waterlogging prevention. Since the elevation of the near-shore zone is not higher than the normal water level of the river, it will not affect the function of the river network to regulate and store rainwater.
