Embodiment 1

[0025] The experimental site is selected in the Yuanmou section of Longchuan Jiang, a first-class tributary of the Jinsha River Basin in Yunnan Province. Monitoring, Ecological Security Assessment and Early Warning Research".

[0026] In the experiment, a set of baffled water distribution channels of the present invention was constructed at a lower position outside the river channel of the Yuanmou section of the Longchuan River, and a diversion channel was excavated by using the terrain height difference to introduce part of the river water into the distribution channel. The canal body adopts a reinforced concrete structure, with 3 purification pools, each of which is 5m long, 3m wide and 1.8m deep.

[0027] like figure 1 As shown, the baffled water distribution channel includes a water inlet 1, a diversion well 2, a purification tank 3 and a water outlet 4; the water inlet 1 is arranged on the top of the inlet end of the water distribution channel, and the water outlet 4 is ...

Abstract

The invention discloses a baffling type water distribution channel for river water quality purification. Three purification pools are sequentially arranged in the water distribution channel, each purification pool is provided with a water inlet and an overflow port, the purification pools are filled with filtering filler, and the water inlet of the water distribution channel, the purification pools and the water outlet are sequentially communicated through diversion wells. And emergent wetland plants can be selectively planted on the surface of the purification tank. Effective space of a river bank is fully utilized, a proper section is selected on the outer side of a natural river channel, the flume is excavated by utilizing terrain height difference to introduce part of river water into the water distribution channel, and the river water flows into the river channel after being subjected to multiple baffling and three-layer filtering purification in the water distribution channel. The effective purification of the river channel water body is realized, and main pollutants in the water body are fully intercepted and removed. Compared with the existing constructed wetland construction technology, the constructed wetland has the advantages of small occupied area, low construction cost, simple construction process, low operation cost, good treatment effect and the like.

Description

technical field [0001] The invention belongs to the technical field of river water ecological environment treatment, and in particular relates to a baffled water distribution channel used for river water purification. Background technique [0002] Rivers are an important part of natural resources, and the water environment of rivers has a very close relationship with social development. A perfect water ecological environmental protection system can promote the recycling of water resources and directly promote economic development. [0003] At present, the water quality purification function is generally not emphasized in the remediation design of river buffer belts. Therefore, when the water quality in the receiving water body deteriorates, the river bank buffer belt cannot be used to purify the receiving water body. How to make full use of the existing buffer zones on both sides of the river as a beneficial supplement to the decentralized treatment of sewage is of great sig...
