Description
本发明涉及一种前置库,特别涉及到一种以景观一体化为特征的前置库处理系统。The invention relates to a pre-library, in particular to a pre-library processing system featuring landscape integration.
随着经济的高速发展,人口的急剧增长以及工业化和城市化进程的加快,氮、磷营养物质向水体的排放量日益增多,湖泊富营养化程度加剧,当污染水体流入到大面积水域时,治理富营养化难度将进一步增大,因此,在入湖河口设置污水处理系统非常必要,其中前置库处理系统是一种比较实用的技术方法。With the rapid development of the economy, the rapid growth of population, and the acceleration of industrialization and urbanization, the emission of nitrogen and phosphorus nutrients to water bodies is increasing, and the degree of eutrophication of lakes is increasing. When polluted water bodies flow into large areas of waters, The difficulty of managing eutrophication will be further increased. Therefore, it is necessary to set up a sewage treatment system at the mouth of the lake. The pre-treatment system is a practical technical method.
经典前置库是在入湖口筑坝,建成位于主体湖泊水库上游的小型水库,用于截留进入主体水库的污染物。在以往前置库系统研究中,主要是集中在丘陵地带,利用天然坡降,来实现泥沙和N、P营养物有效去除,由于需要特殊的地理条件,此技术应用受到了一定的限制。近年来在我国此技术得到了一定的改进,如在专利公开号CN1621622A,公开了一种平原网河地区面源污染强化净化前置库系统,有效解决了地表径流污染物,但只能用于面源污染控制;另外湖口区天然能源驱动的前置库系统(专利公开号CN102134140A)专利,提出在前置库处理系统中增加天然能源驱动装置,将入湖河水引入引水调蓄缓冲区,在分别经过生态拦截与沉降区、强化净化区、深度净化区和生态稳定区,通过各处理区环环净化、步步拦截后,从而降低入湖污染负荷。虽然这些技术解决了库区的进水和强化净化所需要的动力问题,但各区结构简单,净化效果不高,功能单一,仅以净化为目标,缺乏景观化效果。The classic front-loading dam is built in the estuary of the lake, and a small reservoir located upstream of the main lake reservoir is built to intercept the pollutants entering the main reservoir. In the past research of pre-banking system, it mainly concentrated in hilly areas, using natural slopes to achieve effective removal of sediment and N and P nutrients. Due to the special geographical conditions, the application of this technology has been limited. In recent years, this technology has been improved in China. For example, in Patent Publication No. CN1621622A, a non-point source pollution enhanced purification pre-column system in the plain net river area is disclosed, which effectively solves surface runoff pollutants, but can only be used for Non-point source pollution control; In addition, the Hukou District natural energy-driven pre-library system (patent publication number CN102134140A) patent proposes to add natural energy driving devices in the pre-bank processing system, and introduce the water into the water diversion buffer. After passing through the ecological interception and settlement zone, the intensive purification zone, the deep purification zone and the ecological stability zone, the pollution load of the lake is reduced by the loop cleaning and step by step of each treatment zone. Although these technologies solve the power problems required for the influent and enhanced purification of the reservoir area, the structures of each area are simple, the purification effect is not high, and the function is single, and only the purification is targeted, and the landscape effect is lacking.
淹城位于常州市武进区,是我国目前西周到春秋时期保存下来的最古老的城市区,面积约1平方公里,迄今已有将近3000年的历史,这也是世界上仅有的三城三河形制的古城,从里向外,子城、子城河、内城、内城河、外城、外城河,三城三河相套。淹城一座历经沧桑的千年古城,如今依然活力四射,现为全国重要文物保护单位和旅游胜地。参照历史文化背景,将前置库深度净化区设计成三城三河相套几何图形,不仅提高了前置库处理的作用,更增添了自然景观效果,使前置库风光迤逦,美不胜收,实现了处理与景观的有机结合,环境改善与美观享受的统一。

A thousand-year-old city that has experienced vicissitudes in Yancheng is still alive and well. It is now an important cultural relics protection unit and tourist attraction in the country. Referring to the historical and cultural background, the pre-depth deep purification area was designed into the three-city and three-river sets of geometric figures, which not only improved the role of the pre-pool processing, but also added the natural landscape effect, making the front-storage library beautiful and beautiful. Handling the organic combination with the landscape, the unity of environmental improvement and aesthetic enjoyment.

It can only be used for non-point source pollution control, but only for purification. At the same time, the existing pre-pool system has low processing efficiency and lack of landscape observability. Without a good solution, the present invention provides a pre-bank processing system characterized by landscape integration, which has the characteristics of high pollution load treatment efficiency, simple management and landscape effect.
