Technical Field

[0001] The utility model relates to a biological contact oxidation regulating pool, belonging to the technical field of sewage treatment. Background Art

[0002] Usually, small-scale domestic sewage treatment and reclaimed water treatment stations need to set up regulating tanks. The regulating tank plays a role in regulating water volume and balancing water quality. It also has a certain biochemical reaction effect, especially hydrolysis and acidification reaction, which improves the biodegradability of subsequent biochemical reaction facilities. According to the water quality, water volume and treatment facilities, the volume of the regulating tank and the water retention time are different, usually 8~24h. Although the volume of the regulating tank can be increased and the retention time can be extended, there are fewer microorganisms in the regulating tank, the biochemical effect is poor, and the removal efficiency of pollutants in sewage is limited. Therefore, in order to make full use of the existing volume of the regulating tank, improve the biochemical effect of the regulating tank, and then improve the removal efficiency of pollutants in the sewage of the regulating tank, it is necessary to improve the existing technology.

[0005] The circulating water distribution device includes a water pipe connected to the filter outlet pipe, at least one rotating nozzle arranged on the water pipe, and at least one rotating nozzle connected to the water pipe so as to send filtered water to the water pipe, and then to the rotating nozzle to spray on the biological filler to complete biodegradation.

[0006] The circulating water distribution device comprises a plurality of perforated straight pipes or perforated coils connected to the water outlet pipe of the filter, so as to spray the filtered water onto the biological filler through the plurality of perforated straight pipes or perforated coils to complete the biological degradation.

[0007] The biological filler is a floating filler.

[0008] The outlet pump can be used as a backwashing water pump to backwash the tank cavity with external water.

[0009] The utility model has the following advantages and effects:

[0010] 1. The water output is adjusted by water level changes, and the biological fillers set in the regulating pool provide a carrier for microbial biofilm formation, which effectively promotes microbial reaction and improves biochemical reaction efficiency and pollutant degradation efficiency.

[0011] 2. The circulating pump is set up to accelerate the circulation of sewage in the pool and improve the efficiency of biochemical reactions. During the circulation process, the filter removes dirt from the sewage and reduces the load on the biological filler. In addition, the biofilm that falls off the biological filler can also be removed by the filter.

[0012] 3. Through the setting of circulating water distribution device, the filtered water is fully in contact with the air to absorb oxygen in the air, increase dissolved oxygen, form aerobic, anoxic and anaerobic biochemical reactions, and effectively remove pollutants in sewage.
