DM sewage treatment technology

Abstract

The invention relates to the technical field of sewage treatment, and discloses a DM sewage treatment technology, which comprises a guide pipeline, a grating well, an adjusting tank, an integrated sewage treatment device, an anoxic tank, an aerobic tank, a secondary sedimentation tank and a sludge dewatering device, the grating well is arranged on the guide pipeline, the water inlet end of the adjusting tank is connected with the water outlet end of the grating well, the adjusting tank is used for adjusting the water quality of sewage, the water inlet end of the integrated sewage treatment device is connected with the water outlet end of the adjusting tank, the water inlet end of the anoxic tank is connected with the water outlet end of the integrated sewage treatment equipment, and the DM sewage treatment technology is reasonable in design, simple in use method and convenient to operate. According to the DM sewage treatment technology, all modular structures are adopted, extension is easy, the needed occupied land and civil engineering amount is small, the construction period is short, the impact load bearing capacity is high, the influence of low temperature is small, and the reclaimed water recycling requirement is met.

Description

Technical field[0001]The present invention relates to the field of sewage treatment, and more particularly to a DM sewage treatment technique.Background technique[0002]The per capita level of China's freshwater resources belongs to the end of the world, and the water pollution problems generated by the large industrial sound field are increasingly serious. Therefore, the sewage treatment has been concerned with more and more people, and the existing sewage treatment methods include physical precipitation, chemical precipitation. Method, biodegradation, etc., but mostly use of biological treatment methods, including activated sludge, oxidative ditch, SBR method, etc., the shortcomings are the long-term construction period, covering the earth, withstand the impact capacity Weak, affected by the low temperature, long processing time, large amount of sludge, high sludge water content.Inventive content[0003]A DM sewage treatment technique provided by the present invention to solve most o...

AI Technical Summary

Problems solved by technology

[0003] The DM sewage treatment technology provided by the present invention solves the problem that most of the existing sewage treatment methods use biological treatment methods, including activated sludge method, oxidation ditch method, SBR method, etc. The disadvantages are that the construction period is long and the land occupation is large. , the ability to withstand impact load is weak, it is greatly affected by low temperature, the treatment time is long, the amount of sludge is large, and the water content of sludge is high.
