Spiral impurity-removal sewage treatment device

Abstract

The invention discloses a spiral impurity-removal sewage treatment device. The device comprises a treatment box, a spiral pushing device is fixedly connected to the top of the treatment box, and a driving motor is fixedly arranged on the exterior of the treatment box; a middle water tank is fixedly connected to the lower end of a drainage pipe, a catalytic reaction groove is formed below the middle water tank, and a lead screw mechanism is arranged on the catalytic reaction groove; a catalysis plate is fixedly arranged on the lead screw mechanism, an external box is fixedly connected to the side, away from the driving motor, of the treatment box, and the end, away from a spiral shell, of an impurity pipe penetrates through the treatment box and is connected with the external box; a filterdevice is arranged in the external box, and a standing adsorption box and a layering box are fixedly connected to the bottom in the treatment box. According to the spiral impurity-removal sewage treatment device, impurities and small-particle substances in sewage can be separated and removed, partial harmful substances in the sewage can also be subjected to catalytic decomposition, two kinds of impurities in the sewage are discharged in different states, following targeted treatment is conducted conveniently, the sewage is treated simply and effectively, and the device is wide in application range.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a spiral sewage treatment device for removing impurities. Background technique [0002] The economic development of any country in the world will promote social progress, promote the improvement of industrial and agricultural production capacity, and further improve people's lives, but it will also bring different procedures of environmental pollution. Sewage is also one of the sources of environmental pollution. The emergence of this pollution source has attracted the attention of governments around the world, and the topic of water pollution control has been included in the work schedule of the World Environmental Protection Organization. [0003] The Chinese government has always attached great importance to environmental protection. Due to the government's great attention, my country's sewage treatment business has made great progress, but we must clearly see that my country'...

AI Technical Summary

Problems solved by technology

[0004] Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. At present, the existing sewage treatment process is in the development stage, and its treatment method for sewage is extremely simple, resulting in The treatment effect is poor, or it is consumed. The sewage is treated with refined means, but the cost is high. Simple and effective treatment of sewage is the top priority of current development
