Multistage filtering type sewage treatment equipment

Abstract

The invention discloses multistage filtering type sewage treatment equipment. The equipment comprises a tank body, and a gas conversion device is arranged on the outer wall of the tank body. The gas conversion device comprises an anti-backflow elbow, a ventilation pipe, an activated carbon filter screen and a fan. The ventilation pipe is arranged on the outer surface of one end of the anti-backflow elbow, the activated carbon filter screen is arranged on the inner surface of the lower end of the ventilation pipe, the fan is arranged on the outer surface of the other end of the ventilation pipe, a bearing platform is fixedly connected to the inner wall of the tank body, and a compressed air pump is fixedly connected to the outer surface of the upper end of the bearing platform. According tothe multistage filtering type sewage treatment equipment, the sewage treatment capacity is improved, potential safety hazards in the sewage treatment process are reduced, meanwhile, fine treatment atthe ion degree can be carried out, the sewage treatment degree is further improved, the use efficiency is improved, and the equipment has great use prospects and brings huge economic prospects.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a multi-stage filtering sewage treatment equipment. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. fields, and more and more have entered the daily life of ordinary people; at the same time, due to the development of science and technology, the application of multi-level sewage treatment is becoming more and more extensive, which makes the sewage treatment effect more efficient and the water quality after treatment is better. [0003] The sewage treatment equipment used in the past has gas accumulation, which affects the normal operation of the equipment and has potential safet...

AI Technical Summary

Problems solved by technology

[0003] The sewage treatment equipment used in the past has gas accumulation, which affects the normal operation of the equipment and has potential safety hazards. In the process of treatment, oxygen cannot be used to fully neutralize the harmful gas in the treatment liquid to reduce the occurrence of dangerous situations. At the same time, due to the large workload, it is impossible to Effectively clean the impurities attached to the first filter, which is not conducive to the treatment of sewage, and the ion technology cannot be used to further treat the sewage, and the effect of sewage treatment cannot be further improved
