Blue-green algae filter pressing device for water pollution treatment

Abstract

The invention discloses a blue-green algae filter pressing device for water pollution treatment. The blue-green algae filter pressing device comprises a pressure bearing base, wherein a plurality of supporting rods are symmetrically and fixedly connected to the pressure bearing base, mounting blocks are fixedly connected to one side walls of the multiple supporting rods, and a cylinder is fixedlyconnected between the multiple mounting blocks; and a plurality of annular sliding grooves are formed in the cylinder, wherein the sizes of the annular sliding grooves are gradually increased from inside to outside. According to the blue-green algae filter pressing device, compared with traditional one-time extrusion, the mode that blue-green algae is extruded step by step to be subjected to filter pressing to remove water in the blue-green algae is adopted, so that the comprehensive extrusion is finally and actually achieved, but in the step-by-step extrusion process, due to the fact that thearea of the pressed part of the blue-green algae each time is not quite large, and the displacement stroke required for the water in the blue-green algae to flow out is quite small, in the extrusionprocess, the water in the blue-green algae has enough space to be extruded and flow out along gaps among the blue-green algae, the filter pressing water removal effect on the blue-green algae is better, and the use is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of water pollution control, in particular to a cyanobacteria filter press device for water pollution control. Background technique [0002] In recent years, with the rapid development of modern industry and agricultural production, the population of coastal areas has increased, and a large amount of industrial and agricultural wastewater and domestic sewage have been discharged into the ocean, a considerable part of which has been directly discharged into the ocean without treatment, resulting in the degree of eutrophication in coastal areas and harbors. It is becoming more and more serious, and algal blooms often occur. After the death of cyanobacteria, a large amount of dissolved oxygen in the water will be consumed during the decomposition process of cyanobacteria, resulting in an anoxic environment, causing a large number of deaths of shrimp, shellfish, and fish, thereby causing serious water pollution. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when carrying out water pollution control to blue-green algae-polluted waters, the current effective way is generally to salvage the blue-green algae bloom area by means of a salvage ship, but due to the The cyanobacteria carry a lot of water, so the salvage ship has a heavy load, and the salvaged cyanobacteria need to be cleaned once after salvage, which reduces the working efficiency of the salvage ship. Cyanobacteria can remove a large amount of water in the cyanobacteria. However, the existing cyanobacteria filter press generally adopts a one-time extrusion method. The displacement stroke required to come out is very large, and the water does not have enough space to flow out along the gaps between the cyanobacteria, so the efficiency of water removal by press filtration is very poor
