Aeration integration device, control method and rainwater rainwater storage tank

Abstract

The invention discloses an aeration integration device, a control method and a rainwater storage tank. The aeration integration device comprises a power pump and a rotating driver; the power pump is connected with an injection device through a pipeline; the rotating driver is used for driving the injection device to rotate in the rainwater storage tank; the injection device comprises an air inletpipe and an injection pipe, wherein the air inlet is connected with the atmosphere, and the injection pipe is arranged in the rainwater storage tank and connected with the air inlet pipe and the pipeline. According to the integration device, the dissolved oxygen content in sewage can be increased by injecting air-water emulsion, omnidirectional mixing can be conducted on the sewage in the rainwater storage tank, and the storage tank bottom with a large amount of sediment deposition is sprayed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated aeration device, a control method and a rainwater regulation and storage tank. Background technique [0002] When the city is exposed to rain, the runoff often increases, and the rainwater and sewage often converge, increasing the burden on the urban drainage pipe network and sewage pipe network. Especially in the early stage of rainfall, the formed first rain contains a large amount of pollutants. Direct discharge into natural water bodies will cause serious pollution to the water environment. Therefore, it is necessary to add facilities such as primary rainwater regulation and storage tanks to regulate and treat rainwater of different water quality. In the urban drainage system of our country, the application of the first rain storage tank is more and more extensive. [0003] However, after a period of storage of the initial rainwater entering the initia...

Problems solved by technology

However, this method requires relatively large resources, and it cannot completely solve the problem of the blackening and odor of the first rain in the storage tank.

[0004] Moreover, after the initial rainwater entering the primary rain storage tank has been stored for a period of time, there will still be a large amount of sediment deposited on the bottom of the tank. After the sewage is emptied, the bottom of the tank must be washed clean in time, otherwise, once the sediment at the bottom of the tank is hardened, it will be hard to clear

In the prior art, water pipes are generally used on the ground to flush the bottom of the primary rain storage tank, but this flushing method requires the use of water pipes to reintroduce the water source to flush the bottom of the pool, and the second is to flush the bottom of the pool on the ground. Rinse, rinse not strong enough
