Water impounding and purifying device and application method thereof

Abstract

The invention provides a water impounding and purifying device and an application method thereof. The water impounding and purifying device is arranged in the cross section direction of a riverway; an upstream side and a backwater side of the water impounding and purifying device allow water flows in the riverway to pass through; the water impounding and purifying device comprises a water impounding and purifying dam; the main body of the water impounding and purifying dam is of a hollow frame structure; the frame structure is filled with water purifying filler; two lateral sides of the frame structure are a first water flow surface and a second water flow surface; the first water flow surface comprises a first water impounding area covered with a first baffle board and a first water flowing area not covered with the first baffle board; the second water flow surface comprises a second water impounding area covered with a second baffle board and a second water flowing area not covered with the second baffle board; a waterstop bag is connected with the bottom surface of the water impounding and purifying dam; a dam body rotary shaft is connected with the water impounding and purifying dam; a driving mechanism is connected with the dam body rotary shaft; an elevator mechanism bears the water impounding and purifying dam. The water impounding and purifying device can be set into a purifying mode, an updating mode or a flood mode.

Description

technical field

[0001] The invention relates to the technical field of river channel purification, in particular to a water blocking purification device and a method for using the same. Background technique

[0002] At present, some river water bodies are polluted to varying degrees. While the pollution sources are being treated, in-situ water purification technologies such as aquatic plant purification, floating beds, floating islands, and bypass wetland systems have become an important means of treatment. However, in actual engineering, when encountering mountainous streams with a certain slope, the application of the above technologies is often subject to relatively large restrictions. Because mountain stream channels generally have a certain slope, especially in the southeast coastal areas of my country, the mountain stream channels that independently enter the sea have a short flow and a large slope drop over a certain length, sometimes exceeding 1%. There is a lack of ...
