Surface sewage interception system for river

Abstract

The invention provides a surface sewage interception system for a river. A river contains multiple first reaches and multiple second reaches; the first reaches are riverways whose tops are covered, underground rivers or seriously polluted reaches in the riverways; the tops of the second reaches are open, and the second reaches are located on one side or two sides of the first reaches; first sewageinterception walls and second sewage interception walls are constructed along the riverbanks on the two sides of the second reaches; and connecting walls are constructed in the end positions of the first sewage interception walls and second sewage interception walls close to the first reaches. The system includes the riverbanks on the two sides of the second reaches, the first sewage interceptionwalls, the second sewage interception walls and the connecting walls; the first sewage interception walls, the second sewage interception walls and the connecting walls upward extend from the bottomof the river and are higher than the normal water level of reaches; the first sewage interception walls and the second sewage interception walls can separately form sewage collection channels with thecorresponding reaches; the sewage collection channels communicate with the first reaches; and part of riverways enclosed by the first sewage interception walls, the second sewage interception walls and the connecting walls on the second reaches can form water purification channels.

Description

technical field [0001] The invention relates to the technical field of river channel purification, in particular to a river channel surface sewage interception system. Background technique [0002] Due to the development of the city, residents' domestic sewage and industrial wastewater are directly discharged into the river, which has seriously exceeded the self-purification capacity of the river, resulting in serious pollution of the river, making the river narrow and shallow, and some of the river water is black and smelly, and the black and smelly water has become a target for environmental protection. One of the outstanding problems. To this end, governments at all levels across the country have intensified efforts to control black and odorous water bodies. Through the implementation of sewage interception and collection pipes, the construction of underground sewage pipe networks, and sewage treatment plants, the sewage along the rivers is collected and purified, and the...

AI Technical Summary

Problems solved by technology

[0004] 1. The sewage outlets along the river need to be checked one by one. The workload is heavy. All the sewage outlets need to be excavated, buried, connected to the main pipe, and then transported from the main pipe to the sewage plant. The amount of work is large, the investment is high; the impact is large and the time is long , which cost a lot of money and have great construction risks, causing inconvenience to the lives of the masses;

[0005] 2. Some drain outlets are hidden and difficult to find, resulting in incomplete pipe collection and incomplete sewage interception;

[0006] 3 Under normal circumstances, the flow of sewage pipes is not balanced, resulting in sludge accumulation, which will inevitably lead to silting, blockage and difficulty in cleaning after a long time;

[0007] 4. The sewage pipes are buried in the ground, which are easily affected by terrain subsidence, vibration, etc., resulting in rupture, water seepage, etc., and the sewage flows out again. Such faults are more difficult to troubleshoot;

[0008] 5. The height of the sewage outlet is different, which makes it difficult to unify the height of the sewage pipes, which makes the construction difficult and does not adapt to the complex terrain.

[0009] 6. The above-mentioned reasons lead to unstable and unreliable sewage interception and collection pipes, and the purified river water is easily polluted again

[0010] In addition, in the process of river management, it is often found that some rivers are partially covered to form a local underground river, or an underground river is formed due to natural geographical conditions, and the underground river part cannot be purified by traditional treatment methods, so that the river cannot be purified as a whole; Or some river sections in the river are seriously polluted and are not suitable for water purification. At this time, even if the sewage interception wall is built, the heavily polluted river section cannot be used as a water purification channel.
