Device for pretreatment of high-turbidity wastewater and synchronous electric energy generation

Abstract

The invention discloses a device for pretreatment of high-turbidity wastewater and synchronous electric energy generation. The device comprises a box body, a cathode module, iron nets and a mud suction pipe, wherein the box body contains high-concentration wastewater; the cathode module comprises two rolled cathode plates used as cathodes and a waterproof air chamber; the cathode module floats onthe surface of the high-concentration wastewater, and the draft of the cathode module is not less than two-thirds of the height of the cathode module; each of the rolled cathode plates comprises stainless steel meshes, a conductive carbon powder coating and a capacitive carbon powder coating, and the conductive carbon powder coating is applied on the stainless steel mesh facing the air chamber; atleast one iron net is inserted into the high-concentration wastewater outside each of the rolled cathode plates; and the iron nets are electrically connected with an anode power source. According tothe invention, through the arrangement of the air chamber, the cathode module floats on the liquid surface to realize contact with air, so oxygen is provided for a cathode reduction reaction; coagulated matters are removed via coagulation grooves and the mud suction pipe; and thus, the device realizes pretreatment of the high-turbidity wastewater and synchronous electric energy generation.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to a high turbidity waste water pretreatment and synchronous electric energy generating device. Background technique [0002] High turbidity water refers to raw water with high turbidity or high sediment content. When the sediment content in the water reaches a certain level, they will interfere with each other during the sedimentation process, because when the sediment particles are settling, they must squeeze out the same volume of water, this part of the water is forced to rise, and the sinking speed of the particles is crowded As the density of the sediment particles in the water decreases, when the density of the sediment particles in the water is very high, the settlement will be hindered. [0003] High turbidity wastewater refers to wastewater containing high concentrations of suspended pollutants, such as chemical, textile, printing and dyeing industry raw water, and wastew...

AI Technical Summary

Problems solved by technology

[0003] High turbidity wastewater refers to wastewater containing high concentrations of suspended pollutants, such as chemical, textile, printing and dyeing industry raw water, and wastewater rich in algae. The problems in the pretreatment process mainly include high chemical consumption, low water production, and generation equipment. There are many faults and water quality accidents, and the high cost of water treatment, that is, the lack of efficient and low-cost pretreatment methods to achieve the initial removal of pollutants
