Description
技术领域technical field
本实用新型属于市政排水管道技术领域，特别是涉及一种防淤积沉淀清污管道接入弃流雨水井。The utility model belongs to the technical field of municipal drainage pipelines, in particular to an anti-silting and sedimentation cleaning pipeline connected to an abandoned rainwater well.
背景技术Background technique
随着城市化进程的发展和规模的不断扩大，排水管道的淤积、污染物堆积问题日趋严重，目前国内外众多城市的排水管道中存有大量的污染物，出现了不同程度的淤积问题。With the development of urbanization and the continuous expansion of scale, the problem of siltation and pollutant accumulation in drainage pipes is becoming more and more serious. At present, there are a large amount of pollutants in the drainage pipes of many cities at home and abroad, and different degrees of siltation problems have appeared.
排水管道的淤积问题多是由于管道系统中的泥沙以及悬浮固体物沉积所引起的，排水管道中的污水从坡度大的排水管进入坡度小的排水管后流速变小，污水中携带的泥沙以及悬浮固体物很容易在坡度小的管中沉积下来，从而造成排水管道淤积。管道在旱季接纳污水的流量和管道内污水的流速均远小于雨季值，这使得雨季可被污水带走的泥沙以及悬浮固体物在旱季时沉积下来，进而引起排水管道淤积。排水管道中的淤积物如塑料袋、树枝、树叶、淤泥、砂石等会使管道内污水流速降低，并截留油脂和漂浮物，从而降低管道的输送能力，加剧排水管道的淤积，当排水管道中淤积物达到一定程度时，管道的输送能力会急剧下降，淤积物淤积的速度会逐渐加快，最终造成管道堵塞。而且在一些路面径流的研究表明，初期30％雨水径流中的污染负荷占整场降雨污染的 70％，因此，初期雨水的截留与处理可有效控制径流污染物带来的管道淤积。因此，有必要对前期雨水进行预处理，截留水中的淤泥、沙粒、碎石等杂质以及大量污染物，目前，国内外对于排水管道的清淤研究较少，现存的对于管道清淤问题的研究也仅限于在出现管道淤积之后采取的各种措施，因此对于排水管道内部污染物淤积的问题的解决显得尤为重要。The silting problem of the drainage pipe is mostly caused by the deposition of sediment and suspended solids in the piping system. The flow velocity of the sewage in the drainage pipe becomes smaller after entering the drainage pipe with a steep slope from the drainage pipe with a large slope, and the mud carried in the sewage Sand and suspended solids can easily settle in pipes with shallow slopes, causing silting of drains. The flow of sewage received by the pipeline in the dry season and the flow velocity of the sewage in the pipeline are much smaller than the value in the rainy season, which makes the sediment and suspended solids that can be carried away by the sewage in the rainy season deposited in the dry season, which in turn causes the drainage pipeline to silt. Sediments in the drainage pipes, such as plastic bags, branches, leaves, silt, sand, etc., will reduce the flow rate of sewage in the pipes, and trap grease and floating objects, thereby reducing the conveying capacity of the pipes and aggravating the sedimentation of the drainage pipes. When the drainage pipes When the silt in the medium reaches a certain level, the conveying capacity of the pipeline will drop sharply, and the speed of silt accumulation will gradually increase, eventually causing the pipeline to block. Moreover, some road surface runoff studies have shown that the pollution load in the initial 30% of rainwater runoff accounts for 70% of the entire rainfall pollution. Therefore, the interception and treatment of initial rainwater can effectively control the pipeline deposition caused by runoff pollutants. Therefore, it is necessary to pre-treat the rainwater in the early stage to retain impurities such as silt, sand, gravel and a large number of pollutants in the water. The research is also limited to various measures taken after pipeline siltation occurs, so it is particularly important to solve the problem of pollutant siltation inside the drainage pipeline.
现今市政管道的建设错综复杂，有很多管道因为管道内部污染物淤积的问题无法正常运行，浅层的错综复杂的管道又不能破坏，那么深层雨污水管道的建设势在必行，深层雨污水管道的运行有一个很大的问题，那就是不管雨水、污水经过怎样的处理进入深层管道都会在长时间的积累下产生淤泥，而且又不好清理，一旦淤泥达到一个量值时会造成很大的危害，雨水井与水的净化与清淤功能相结合十分有利，有效避免了沙粒、碎石、淤泥等污染物的沉淀，极易造成管道堵塞的情况。Nowadays, the construction of municipal pipelines is complicated. Many pipelines cannot operate normally due to the accumulation of pollutants inside the pipelines. The shallow and intricate pipelines cannot be damaged. Therefore, the construction of deep rainwater and sewage pipelines is imperative. The operation of deep rainwater and sewage pipelines There is a big problem, that is, no matter how the rainwater and sewage are treated and enter the deep pipeline, sludge will be accumulated for a long time, and it is not easy to clean. Once the sludge reaches a certain value, it will cause great harm. The combination of rainwater wells and water purification and desilting functions is very beneficial, effectively avoiding the precipitation of sand, gravel, silt and other pollutants, which can easily cause pipeline blockage.

该系统的工作步骤为初期雨水进入雨水管道舱3，经过截污斜网4过滤后，进入储存净化箱10，雨水经过截污斜网4过滤后的淤泥通过可沉淀格栅6上的底部沉淀口7进入沉淀清淤槽26，淤泥通过高扬程清污泵8、淤泥输出管道9排出，经过初步过滤后的雨水进入储存净化箱10后，再经过活性炭芯过滤层12、除油层13、无纺土工布层14过滤后进入弃流集水控制腔20，若降雨量稍小，当弃流集水控制腔20中雨水没有达到漂浮球16的高度时，滑动活塞18套在活塞滑道17的底部且刚好套住弃流集水控制腔控制孔19，在弃流集水控制腔20中实现雨水的快速收集并储存；若降雨量再大，弃流集水控制腔20内液面不断上升，当弃流集水控制腔20中雨水不断上升至漂浮球16高度时，弃流集水控制腔20中雨水上升使漂浮球16向上移动，漂浮球16通过连接杆15带动滑动活塞18向上滑动，滑动活塞18离开弃流集水控制腔控制孔19，此时，弃流集水控制腔20中多余的雨水可通过弃流集水控制腔控制孔19进入弃流落水管21，再通过排水管道22进入雨水管道23排出，雨量逐渐减小停止时，弃流集水控制腔20中的雨水逐渐降低使漂浮球16向下移动，漂浮球16通过连接杆15带动滑动活塞18向下滑动直至滑动活塞18套住弃流集水控制腔控制孔19，将雨水收集并储存在弃流集水控制腔20中，使用时通过水泵24、抽水管25排出，且可通过雨水井盖11清掏储存净化箱10中过滤后的杂质，并对活性炭芯过滤层12、除油层13、无纺土工布层14进行更换。The working procedure of this system is that the initial rainwater enters the rainwater pipeline cabin 3, and after being filtered by the sewage intercepting inclined net 4, enters the storage purification tank 10, and the rainwater is filtered by the sewage intercepting inclined net 4, and the sludge is deposited through the bottom on the sedimentable grid 6 The port 7 enters the sedimentation dredging tank 26, and the sludge is discharged through the high-lift cleaning pump 8 and the sludge output pipeline 9. After the preliminary filtered rainwater enters the storage purification tank 10, it passes through the activated carbon core filter layer 12, the oil removal layer 13, and the After the geotextile layer 14 is filtered, it enters the waste water collection control chamber 20. If the rainfall is slightly small, when the rainwater in the waste water collection control chamber 20 does not reach the height of the floating ball 16, the sliding piston 18 is set on the piston slide 17. and just cover the control hole 19 of the abandonment water collection control chamber, the rapid collection and storage of rainwater is realized in the abandonment flow water collection control chamber 20; Ascending, when the rainwater in the waste water collection control chamber 20 continues to rise to the height of the floating ball 16, the rainwater in the waste water collection control chamber 20 rises to make the floating ball 16 move upward, and the floating ball 16 drives the sliding piston 18 upward through the connecting rod 15 Sliding, the sliding piston 18 leaves the control hole 19 of the waste water collection control chamber. At this time, the redundant rainwater in the waste water collection control chamber 20 can enter the waste water downpipe 21 through the waste water collection control chamber control hole 19, and then pass through the drain The pipeline 22 enters the rainwater pipeline 23 to discharge, and when the rainfall gradually decreases and stops, the rainwater in the discarded flow collection control chamber 20 gradually decreases to make the floating ball 16 move downward, and the floating ball 16 drives the sliding piston 18 to slide downward through the connecting rod 15 until The sliding piston 18 covers the control hole 19 of the waste water collection control chamber, and collects and stores the rainwater in the waste water collection control chamber 20. When in use, it is discharged through the water pump 24 and the suction pipe 25, and can be cleaned and stored through the rainwater well cover 11. Purify the filtered impurities in the box 10, and replace the activated carbon core filter layer 12, degreasing layer 13, and non-woven geotextile layer 14.
