Electrochemical water treatment device and method utilizing same to treat water

Abstract

The invention provides an electrochemical water treatment device which comprises a reaction device, a tangential water inlet formed in the side wall of the upper portion of the reaction device, a water outlet formed in the lower end of the bottom, a drain outlet formed in the side wall of the bottom, a primary coarse filtration screen arranged at the top of the center of the inside of the reaction device, an anode arranged below the primary coarse filtration screen, a secondary fine filtration screen, a cathode, a power supply and a vent valve. The invention further provides a method utilizing the device to treat water. Compared with the prior art, the synergic coupling effect of all processes is achieved within the same reaction device by adopting an ingenious process concept, so that the processes are complementary and are promoted mutually to overcome the shortcomings existing when the processes respectively play the effects, the treatment effect is remarkably improved, the energy consumption is reduced, a reactor structure is optimized, and the occupied area is reduced. The method utilizing the device to treat water is simple in process, high in treating efficiency and capable of performing effective, economical, environmentally friendly and integrated water treatment through hydraulic cyclone separation, two-stage filter screen based filtration and electrochemical oxidation and reduction.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, and in particular relates to an electrochemical water treatment equipment, and also relates to a water treatment method using the equipment. Background technique [0002] With the continuous development of modern industry, the impact of water pollution on the environment is becoming more and more serious, directly threatening human health and ecological security. Due to the influence of water quality, traditional sewage treatment methods are often difficult to achieve satisfactory results, and have high energy consumption, large volume, incomplete degradation, and even secondary pollution. Therefore, the integrated treatment equipment and technology with small size, high efficiency and easy operation have always been a difficulty and research hotspot in domestic and foreign water treatment work. [0003] Filtration treatment of sewage is easy to operate and has no pollution, and is often...

AI Technical Summary

Problems solved by technology

However, electrochemical technology is difficult to remove solid substances in water, and the treatment efficiency is greatly affected by water quality. When the conductivity of the water body is low, the effect of electrochemical treatment alone is poor.

In addition, the contamination of the electrode by impurities in the water shortens the life of the electrode, and its application is limited.

[0004] The existing water treatment often realizes the combined application of different processes by constructing series structures, but it occupies a large area and the operation and management are cumbersome
