Sewage treatment flocculation device based on biofilm process treatment technology

Abstract

The invention relates to the technical field of sewage treatment, and discloses a sewage treatment flocculation device based on a biofilm process treatment technology, the sewage treatment flocculation device comprises a mixing cylinder, the mixing device comprises a piston block, a first fixed block, a first rotating cover, a second fixed block, a second rotating cover and a promoting device, the piston block is slidably connected to the interior of the mixing cylinder, and the piston block is slidably connected to the interior of the mixing cylinder. A first fixing block is fixedly connected to the piston block, a first rotating cover is rotatably connected to the outer side of the first fixing block, and a second fixing block is fixedly connected to the inner bottom side wall of the mixing cylinder. According to the sewage treatment flocculation device based on the biofilm process treatment technology, through the cooperative action of a second motor, a rotating disc, a connecting rod, a sliding block, a track plate, a track shell, a moving rod, a piston block, a first rotating cover, a second rotating cover, a mixing cylinder, a first motor, a screw rod, a filter cylinder and a rotating fan, the purpose of accelerated mixing of a flocculating agent and water is achieved; therefore, the problem of low flocculation effect is solved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment flocculation device based on a biological membrane method treatment technology. Background technique [0002] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. There are many methods for sewage treatment, which can generally be classified into physical methods, chemical methods and biological methods. Biofilm method is side by side with activated sludge method. A type of wastewater aerobic biological treatment technology is a fixed membrane method, which is the artificialization and strengthening of the self-purification process of sewage and soil, mainly to remove soluble and colloidal organic pollutants in wastewater. At the same time, a flocculant can be used. After the flocculant is dissolved in water, the fine particles and natural colloidal part...

AI Technical Summary

Problems solved by technology

[0003] The existing sewage treatment flocculation device mainly has the following technical defects: First, the use of the traditional flocculation device mainly sprinkles the flocculant into the sewage sedimentation tank using the biofilm treatment technology through the throwing mechanism, because the flocculant is In order to fix the particles, the flocculant cannot quickly react with the sewage, and at the same time the flocculant cannot fully contact with the sewage, resulting in the problem of low flocculation effect; second, if the flocculant is first mixed with water and then discharged into the sewage tank However, there is a problem that the amount of flocculant added cannot be positively related to the water flow, which leads to the failure of the dosage of flocculant to reach an appropriate state, resulting in the problem of low degree of flocculation or waste of flocculant
