Circulating ventilation system of silica sand water storage and purification tank

Abstract

The invention relates to a circulating ventilation system of a silica sand water storage and purification tank, belongs to the technical field of environmental engineering, and provides the following technical scheme for solving the problem that purification treatment of sewage is not facilitated, the circulating ventilation system of the silica sand water storage and purification tank is technically characterized by comprising a tank body, impermeable layers are laid on the bottom wall and the side wall of the tank body, and a water storage well and a water purification well are arranged in the tank body; the water storage well and the water purification well are both defined by silica sand water filtering walls, the water purification well is communicated with a water inlet pipe, and the water storage well is communicated with a water outlet pipe. A desilting channel is further arranged in the tank body, the desilting channel is communicated with the water purification well, and the desilting channel is provided with a sludge discharge pipe; an air inlet pipe is arranged in the tank body, the two ends of the air inlet pipe extend out of the tank body, an air channel capable of supplying air to the air inlet pipe is arranged outside the tank body, and a plurality of air outlet holes are formed in the air inlet pipe located in the tank body. The circulating ventilation system has the advantages of increasing the content of dissolved oxygen in sewage and improving the sewage filtering effect.

Description

technical field [0001] The application relates to the technical field of environmental engineering, in particular to a circulation and ventilation system for a silica sand water storage and purification pool. Background technique [0002] With the development of urbanization, the runoff of rainwater increases, and the peak flow of rainwater runoff is temporarily stored in the storage tank. After the flow drops, the water is discharged from the storage tank to reduce the peak flow and reduce the downstream rainwater. Increase the diameter of the main pipe, improve the drainage standard and flood control capacity of the area, and reduce waterlogging disasters. However, when regulating rainwater, it is also necessary to effectively purify the rainwater. The untreated rainwater cannot be directly discharged into the river to pollute the river water. Therefore, it is necessary to simultaneously purify the rainwater while regulating the rainwater. [0003] However, after the init...
