Vehicle-mounted algae-water separation and tail water treatment device and working method thereof

Abstract

A vehicle-mounted algae-water separation and tail water treatment device comprises a sewage suction pump, a hydraulic vibrating screen, an extrusion type spiral elevator, an algae mud collecting box,a tail water tank, a centrifugal water spraying pump and a greening water spraying nozzle which are all arranged on an auxiliary frame of a lorry; the sewage suction pump is used for pumping an algae-mud mixture with a high water content into the hydraulic vibrating screen from a channel or a river; the hydraulic vibrating screen realizes separation of the algae-mud mixture and water; and the algae-mud mixture is conveyed into the algae-mud collecting box through the extrusion type spiral elevator. The separated tail water enters the tail water tank, is pressurized by the centrifugal water spraying pump and is conveyed to the greening water spraying nozzle, so that a function of spraying and irrigating slope green belts is realized. The algae-water separation and tail water treatment process is environmentally friendly, meets the requirement for ecological algae-water separation, and has the advantages of that operation efficiency is high, environmentally friendliness is achieved, energy is saved, safety and reliability are achieved; moreover, secondary pollution of chemical flocculants to water quality is avoided; and great significance is achieved in guaranteeing channel water quality and water delivery safety.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a vehicle-mounted algal water separation and tail water treatment device and a working method thereof, which are suitable for water areas such as channels, rivers, inland lakes and landscape water bodies. Background technique [0002] With the acceleration of social industrialization, human beings discharge a large amount of pollutants containing nitrogen and phosphorus into water bodies in production and daily life, which accelerates the eutrophication process of slow-flowing water bodies such as lakes and reservoirs, thus causing algae to grow. The frequent outbreak of "water bloom" phenomenon has seriously damaged the ecological balance of the water body and endangered the safety of human beings and other living things. On the one hand, the growth of algae reduces the transparency of the water body, making it difficult for sunlight to penetrate the water la...

Problems solved by technology

[0005] At present, the commonly used algae water separation methods include air flotation method and flocculation sedimentation method. These methods need to add chemical flocculants to the water body. Therefore, there is a secondary pollution problem to the tail water, which increases the difficulty and difficulty of tail water treatment. processing cost
