A device for enrichment and removal of suspended particulate matter in water body

Abstract

The invention discloses a device for enriching and removing suspended particles in a water body. The device comprises a box body, a particle obtaining device and a flow pushing device, wherein the boxbody comprises a frame, two opposite side plates and a bottom plate connected to the bottoms of the two side plates; the side plates are arranged in the water flow direction, and gill rake rod holesare formed in the opposite positions of the two side plates; a gill rake rod penetrates through each pair of gill rake rod holes, the upper portions of the gill rake rods are fixedly connected with filter membranes, and the top ends of the filter membranes can freely float; strip-shaped floating bodies perpendicular to the gill rake rods are arranged on the filter membranes, the width of the filter membranes is larger than or equal to the distance between the two side plates, and the particle obtaining device is arranged at the upper part of the downstream end of the box body; an obtaining opening of the particle obtaining device faces the water flow direction, and the flow pushing device is arranged at the lower part of the downstream end of the particle obtaining device; the flow pushingdirection of the flow pushing device is consistent with the water flow direction. The device adopts a physical mode, and can remove the suspended particles in the water body in a large-flow and low-energy-consumption mode; the density of the particles in the water body can be effectively reduced, and particularly, the density of cyanobacteria can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of water environment engineering, and in particular relates to a device for removing particles, in particular to a device for efficiently enriching and removing suspended particles in a water body, including algae particles, which is suitable for lakes, rivers, reservoirs, oceans and other natural water bodies and urban landscape water bodies. Background technique [0002] At present, there is no effective means to enrich and remove suspended particulates in water bodies. A large number of suspended particulates affect the transparency of water bodies and pollute the water environment, especially particulate matter such as algae. Algae are distributed in different water layers of the water body, and their vertical distribution is affected by environmental factors such as light intensity, wind speed, flow field, transparency, and nutrient salts, forming the diurnal variation characteristics of the algae density distribu...

Problems solved by technology

However, the current algae removal device is mainly aimed at accumulating cyanobacteria on the surface, and its ability to deal with suspended cyanobacteria in the water body is limited. Visually, the cyanobacteria on the surface of the water body can be controlled in a short period of time, but the cyanobacteria in the water column will soon float up and form a new bloom.
