The invention discloses a comprehensive pool integrating functions of pollutant emission reduction, storage regulation, conditioning and denitrification, and belongs to the technical field of municipal drainage or environmental engineering. The comprehensive pool comprises: a turbid water regulation area, which is connected with the output end of an integrated biochemical reaction pool and used for receiving turbid water generated by the integrated biochemical reaction pool and regulating water quality; a sedimentation area, which is connected with the turbid water regulation area and used forperforming sedimentation treatment on the turbid water discharged from the turbid water regulation area and converging a sedimentation effluent into the effluent box culvert of the integrated biochemical reaction pool; and an overflow storage regulation area, which is used for regulating storage of overflow sewage exceeding the treatment scale of a sewage plant or used as a prepositioned denitrification pool of the integrated biochemical reaction pool in the sewage plant to play a denitrification function. By application of the comprehensive pool provided by the invention, the emission amountof pollutants in the sewage plant can be greatly reduced, and the quality of a water environment can be greatly improved.
Description
technical field [0001] The invention discloses a comprehensive pool in a sewage treatment plant that takes into account the functions of pollutant discharge reduction, storage and conditioning, and denitrification and a method for improving the water environment, belonging to the technical field of municipal drainage or environmental engineering. The invention is applicable to the sewage treatment plants which do not consider overflow water regulation and storage in the present situation or the sewage treatment plants which adopt the integrated activated sludge process. Background technique [0002] Sewage treatment is an important means of pollutant emission reduction in urban water systems. As an important part of urban environmental infrastructure construction, urban sewage treatment plants and supporting pipe network systems play a key role in urban water pollution control and water environment improvement. [0003] At present, more and more drainage pipes are built in c...
