Embodiment 1

[0035] Example 1: Build and install two filter walls, filter wall I3 and filter wall II5, and two partition walls, partition wall I2 and partition wall II4, in the river course. The upstream sedimentation zone of filter wall I3 is formed between the filter wall I3, the partition wall I2 and the right bank, and the upstream sedimentation zone of filter wall II5 is formed by the filter wall II5, partition wall II4 and the left bank, and the river water passes through the two filter walls respectively and enters the downstream channel , the solid pollutants in the river water are intercepted by two filter walls and deposited or floated up in the two sedimentation areas to remove them; In the fish channel, aquatic animals such as fish in the river swim downstream or migrate upstream through the fish channel.

[0036] Described fish type sedimentation filter tank, its mode of operation is as follows:

[0037] 1) First filtration: part of the river water flows downstream after be...

Embodiment 2

[0040] Example 2:In the downstream section of the fish-passing sedimentation filter described in Example 1, there may be hydraulic structures or other facilities, which are not conducive to the survival of aquatic animals such as fish, or aquatic animals such as fish may affect the hydraulic structures. For the operation, it is necessary to set up a special channel to allow fish and other aquatic animals to enter the downstream water body or migrate to the upstream channel. After improvement, a fish-passing sedimentation filter tank with a fish-passing channel is obtained.

[0041] Build and install three filter walls, filter wall I3, filter wall II5 and filter wall III9, and two partition walls, partition wall I2 and partition wall II4, in the river course. The upstream sedimentation zone of filter wall I3 is formed between the filter wall I3, the partition wall I2 and the right bank, and the upstream sedimentation zone of filter wall II5 is formed by the filter wall II5, pa...

Abstract

The invention belongs to the field of water pollution treatment and control, and especially relates to a fish-passing type sedimentation filtering basin capable of removing solid pollutant in rivers. Filtering walls and baffle walls are constructed in a river, the filtering walls, the baffle walls and the river banks form a sedimentation area and leaves a fish-passing channel, river water passes through the filtering walls and enters a downstream river channel, solid pollutants are intercepted at the sedimentation area and are deposited or floats upwards and removed, fish in river passes the fish-passing channel and swims towards the downstream or migrates towards the upstream. The fish-passing sedimentation filtering basin is directly constructed in the river, runs depending on river water flowing, is capable of effectively removing solid pollutants in the river channel, solves the river black and odorous problems, does not influence flood prevention and fish passing, and is low in investment and running cost.

Description

Technical field [0001] The present invention is a field of water pollution control and prevention, and specially involves an overfish sedimentation filter that removes solid pollutants in the river. Background technique [0002] The Water Pollution Prevention Action Plan issued on April 16, 2015.This document, known as "Water Ten", has attracted great concern to society."Ten Water" has clear requirements for black and odorous water bodies. By 2020, the black and odorous water bodies of cities above and above will be controlled within 10%. By 2030, the city's black and odorous water bodies will be eliminated.Some experts pointed out that the treatment of black and odorous water bodies in cities and towns is the most difficult content in the "Ten Water". [0003] Solid -state pollutants are one of the main pollutants in the river. Solid -state pollutants in the river are one of the main reasons for the river channels to become black. In additionOne of the pollutants that are most i...
