A kind of urban river management system and its river reconstruction method

Abstract

An urban river course management system, including a clear water area, a sewage treatment system and a reclaimed water treatment system. The clear water area adopts the original river course, divides the urban river course into several sections, and builds dams to store water in each section. Under the dam body (8) There are drainage holes (7); the reclaimed water treatment system is to build reclaimed water canals (1) on both sides of the river section between the reclaimed water discharge outlet and the entrance of the downstream reclaimed water collection lake, and the middle and upper parts of the reclaimed water canal (1) are equipped with sewage The collecting pipe (2); the downstream side of the dam body (8) is provided with a connecting canal (6) connecting the canals (1) on both banks; the node (4) between the canals (1) in the two sections of the river is equipped with guides The valve (3), the reclaimed water channel (1) is connected with the connecting channel (6) through the pilot valve (3); a multi-stage biological purification system is arranged downstream of the reclaimed water channel (1). The present invention adopts the methods of "segmentation and governance", "water division and governance", "cross-strait communication" and "three water diversions" to control urban rivers, effectively improve the water quality of rivers, and enhance the charm and image of urban rivers.

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
