Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to multi-directional circulation high-efficiency denitrification sewage treatment equipment. Background Art

[0002] With the rapid development of industry and the rapid improvement of daily living standards, the industrial wastewater or domestic sewage generated needs to be safely treated. For example, if the nitrogen element in the sewage exceeds the standard, it will cause eutrophication of the water quality, so it needs to be denitrified. In the existing sewage treatment, microorganisms are usually used to carry out ammoniation, nitrification and denitrification reactions on the organic nitrogen and ammonia nitrogen in the sewage, so that the organic nitrogen and ammonia nitrogen in the sewage are converted into nitrogen gas, thereby realizing efficient denitrification operation of the sewage. However, when the sewage is currently denitrified, the microorganisms are generally placed directly into the treatment pool and treated by static sedimentation. This method results in poor denitrification efficiency, long treatment time and low work efficiency. Therefore, we propose a multi-directional circulation high-efficiency denitrification sewage treatment equipment to solve the above problems. Utility Model Content

A filter box 3 is fixed on the main box body 2, and a discharge pipe 19 is connected and fixed at the discharge port of the filter box 3. One end of the discharge pipe 19 is threadedly connected with a pipe cover 20. After the pipe cover 20 is separated from the discharge pipe 19, the impurities filtered inside the filter bucket 4 can be conveniently discharged.
