Filter wall used in riverway

Abstract

The invention belongs to the technical field of water pollution treatment and prevention, and relates to a filter wall used in a riverway. The filter wall is characterized by comprising a first filterwall, a base, supporting seats, a spring, a movable inclined block, L-shaped guide plates and a second filter wall; the base is fixedly arranged at the bottom end of the first filter wall, the supporting seats are fixedly arranged on the upper end face of the base and located at the left end and the right end of the base correspondingly, the L-shaped guide plates are connected to the upper end faces of the supporting seats correspondingly, and one side edges of the L-shaped guide plates are fixedly connected with the front end face of the first filter wall; and the second filter wall is arranged between the L-shaped guide plates and the first filter wall and can move up and down in a space formed by the L-shaped guide plates and the first filter wall. Therefore, the second filter wall canmove up and down in the space formed by the L-shaped guide plates and the first filter wall according to the change of the water level, the riverway is more attractive due to the descending of the second filter wall when the water level is lower, and floating solid pollutants can be intercepted when the water level rises.

Description

technical field [0001] The invention belongs to the technical field of water pollution control and prevention, and in particular relates to a filter wall used in a river channel. Background technique [0002] Previously, a Chinese patent with the patent number CN201510529513.6 disclosed a fish-passing sedimentation filter tank. Filter walls and partition walls were built and installed in the river. Channel, the river water passes through the filter wall and enters the downstream channel, in which the solid pollutants are intercepted in the sedimentation area to settle or float up for removal, and the fish in the river swim downstream or migrate upstream through the fish-passing channel. The fish-passing sedimentation filter tank is directly built and installed in the river, and relies on the flow of river water to effectively remove solid pollutants in the river. This design can effectively solve the problem of black and odor in the river, without affecting flood control and...

AI Technical Summary

Problems solved by technology

The fish-passing sedimentation filter tank is directly built and installed in the river, and relies on the flow of river water to effectively remove solid pollutants in the river. This design can effectively solve the problem of black and odor in the river, without affecting flood control and fish traffic. Investment and The operating cost is low, but the water level in the river is constantly changing, and the height of the filter wall cannot be changed; if the wall is built high, it will be very prominent in the dry season of the river and will affect the beauty of the river; if it is built low, the water level will rise. , there is no filtering effect on the floating solid pollutants
