Regulation and storage pond with processing function

Abstract

The invention discloses a regulation and storage pond with a processing function. The regulation and storage pond comprises a regulation and storage zone, a reaction zone, a diversion zone and a settling zone, wherein the regulation and storage zone is provided with a water inlet box culvert, the reaction zone is provided with a stirrer, the settling zone is provided with a water outlet and a mud discharge pipe, the reaction zone, the diversion zone and the settling zone are all arranged on the upper end face of the regulation and storage zone; a lift pump used for transporting the waste water from the regulation and storage zone to the reaction zone is arranged between the reaction zone and the regulation and storage zone, and the diversion zone used for guiding the mixed solution in the reaction zone into the settling zone is arranged between the reaction zone and the settling zone. According to the invention, after entering into the regulation and storage zone, the waste water enters into the upper-layer reaction zone through the lift pump, and carries out reaction in the reaction zone, then the waste water overflows and is guided into the settling zone through the diversion zone to be settled and filtered out of water, thus the waste water can be effectively processed in time; the regulation and storage pond disclosed by the invention has the advantages of simple and compact structure, small occupation area, low energy consumption, is easy to manage and operate, and the regulation and storage pond can effectively improve the water quality of processed water.

Description

technical field [0001] The invention relates to the technical field of sewage treatment ponds, in particular to a storage pond with treatment functions. Background technique [0002] Since the reform and opening up, the Shanghai municipal government has invested heavily in the construction of the first phase of combined sewage treatment, the second and third phases of sewage treatment, and the comprehensive improvement of Suzhou Creek. Significant improvements have been made. At present, the black and smelly rivers in the central city have been basically eliminated, and 85% of the point source pollution in the central city has been intercepted. However, after the water environment quality has been improved to a certain extent, it is more difficult to improve. The main reason is that there is no effective treatment method for the non-point source pollution of urban rainwater in the early stage, which leads to the increasing contradiction of the initial rainwater pollution to ...
