Problems solved by technology
[0002] Urban domestic sewage is mainly the discharge water produced by various kitchen water, washing water and toilet water used in human life. The nitrogen and phosphorus content in the sewage is relatively high. The removal effect of nitrogen and phosphorus is not good, which will lead to eutrophication of water body after discharge of sewage, which will deteriorate the water environment

The invention relates to the technical field of sewage treatment, in particular to a combined biological nitrogen and phosphorus removal device and a method for urban domestic sewage. The combined biological nitrogen and phosphorus removal device for urban domestic sewage comprises a filter box, a water inlet pipe, a biological box, a rotating shaft, a motor, a mounting roller, a plurality of biological plates, a mixing box, a water pumping mechanism, a chemical adding mechanism and a water outlet pipe; sewage is introduced into the filter tank through the water inlet pipe to filter impurities and then flows into the biological tank after impurities in the sewage are filtered; the motor drives the rotating shaft and the mounting roller to rotate, and the mounting roller drives a plurality of biological plates to rotate in sewage, so that nitrogen and phosphorus in the sewage are removed; sewage in the biological box can be guided into the mixing box through the water pumping mechanism, a purifying agent is added into the mixing box through the agent adding mechanism, nitrogen and phosphorus in the sewage are further removed, the purified sewage is guided out of the mixing box through the water outlet pipe, the removal effect of nitrogen and phosphorus in the sewage is improved, and water environment deterioration caused by discharging is prevented.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a combined biological nitrogen and phosphorus removal device and method for urban domestic sewage. Background technique [0002] Urban domestic sewage is mainly the discharge water produced by various kitchen water, washing water and toilet water used in human life. The nitrogen and phosphorus content in the sewage is relatively high. The removal effect of nitrogen and phosphorus is not good, which will lead to eutrophication of water body after sewage discharge, which will deteriorate the water environment. Contents of the invention [0003] The object of the present invention is to provide a combined biological denitrification and phosphorus removal device and method for urban domestic sewage, so as to improve the removal effect of nitrogen and phosphorus in sewage. [0004] In order to achieve the above object, in the first aspect, the present invention provides a ...
