Urban river regulation system and river reconstruction method

Abstract

The invention discloses an urban river regulation system. The urban river regulation system comprises a clear water area, a sewage treatment system and a reclaimed water treatment system, wherein in the clear water area, an original river is adopted, an urban interior river is divided into a plurality of sections, a dam is constructed in each section for water storage, and drain holes (7) are formed in the bottom of each dam body (8); according to the reclaimed water treatment system, reclaimed water channels (1) are built in both sides of a river section between a reclaimed water drainage outlet and an inlet of a downstream reclaimed water collecting lake reservoir respectively, and a sewage collecting pipe (2) is arranged at the inner middle upper part of each reclaimed water channel (1); a connecting channel (6) connecting the reclaimed water channels (1) in both sides is arranged on the downstream side of each dam body (8); a guide valve (3) is mounted at a node (4) between the reclaimed water channels (1) of two river sections, and each reclaimed water channel (1) is connected with the connecting channel (6) through the guide valve (3); a multi-stage biological purification system is arranged at the downstream part of each reclaimed water channel (1). The urban river is regulated by using a sectional regulation method, a water separation regulation method, a both-side communication method and a three-water shunting method, the water quality of the river is effectively improved, and the charm of the urban river and the urban image are improved.

Description

technical field [0001] The invention belongs to the field of urban construction and environmental protection, and in particular relates to an urban river course management system and a river course reconstruction method thereof. Background technique [0002] With the development of urban scale and economic society, urban rivers are polluted to varying degrees. Some rivers are turbid to varying degrees, dry all year round, less clear water and more water, eutrophication makes it difficult for some aquatic organisms to survive, and even mixed with fishy smell. It takes a long time and a lot of money to make the bank green, The scenery becomes beautiful, but in the end, it is too difficult to improve the water quality and the water cannot be cleared. There is an embarrassing situation of beautiful scenery and sewage, and it is difficult to achieve satisfactory results. [0003] Traditional treatment methods are difficult to solve the following outstanding problems: (1) The wat...

Problems solved by technology

Some rivers are turbid to varying degrees, dry all year round, less clear water and more water, eutrophication makes it difficult for some aquatic organisms to survive, and even mixed with fishy smell. It takes a long time and a lot of money to make the bank green, The scenery becomes beautiful, but in the end, it is too difficult to improve the water quality and the water cannot be cleared. There is an embarrassing situation of beautiful scenery and sewage, and it is difficult to achieve satisfactory results.

[0003] Traditional governance methods are difficult to solve the following outstanding problems: (1) Poor water quality in rivers

The river bank reconstruction and river channel reconstruction did not divert the sewage, reclaimed water and clear water, and mostly relied on biological methods to repair the river channel, which made the project huge and costly
