Heavy metal processing wastewater treatment system

Abstract

The invention belongs to the technical field of wastewater treatment, and particularly relates to a heavy metal processing wastewater treatment system which comprises an equipment main body, a controller and an external power supply, the controller is electrically connected with an external power supply, the equipment main body is designed to be funnel-shaped, the upper end of the equipment body is covered with an equipment top cover, a liquid inlet pipe is fixedly connected to the center of the outer surface of the upper end of the equipment top cover, and air outlet holes are evenly formed in the peripheral edge of the outer surface of the equipment top cover. The air outlet hole and the liquid inlet pipe penetrate through the equipment top cover, the outer surface of one end of the equipment main body is fixedly connected with a high-frequency pulse power supply, the high-frequency pulse power supply is electrically connected with the controller, and the outer surface of the equipment main body is fixedly connected with a mounting plate below the high-frequency pulse power supply. The system has the advantages that the sewage treatment equipment is good in purification effect and high in cleanliness, sludge can be effectively prevented from entering purified water, and the sewage treatment equipment is simple, convenient, time-saving and labor-saving to clean after purification is completed.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to a heavy metal processing wastewater treatment system. Background technique [0002] In the process of heavy metal processing, water needs to be used for processing, and the used water will be polluted by heavy metal ions and cannot be directly discharged or reused. Therefore, certain treatment and processing of wastewater is required, and the treatment of this wastewater not only needs to remove Sludge precipitation also needs to remove heavy metal ions in water, which are generally treated by physical and chemical methods. [0003] In the prior art, in the sewage treatment process, since the outlet of the purified water is usually located at the bottom of the equipment, it is very easy to cause the sludge to be discharged along with the purified water during the discharge process, resulting in a decline in the cleanliness of the purified water, which requires more w...

Problems solved by technology

[0004] In order to make up for the shortcomings of the existing technology and solve the problem of low wastewater purification efficiency, sludge will be accompanied in the process of discharging the purified water, which will affect the purification effect. In the later stage, repeated purification is required, which is time-consuming and laborious, and it is difficult to clean the equipment after wastewater purification. Problem, a kind of heavy metal processing waste water treatment system that the present invention proposes
