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.
Therefore, there is an urgent need for a new method to solve the problems of blackening and smelling after the first rain in the storage tank is stored for a period of time.

Abstract

The invention discloses a rainwater storage tank injection type aeration device, an aeration method and a rainwater storage tank, which comprises an air inlet pipe, an injection pipe and a power pumpwhich are interconnected. An air inlet end of the air inlet pipe is in contact with atmosphere and an air outlet end is connected with an air inlet end of the injection pipe and the power pump. An injection end of the injection pipe is arranged in the rainwater storage tank. The rainwater storage tank injection type aeration device can eject gas-liquid mixture from underwater sprinkler irrigationduring water storage, increase the content of dissolved oxygen in sewage, conduct aeration on the sewage in the rainwater storage tank, increase the content of dissolved oxygen in sewage, and solve the problems that sludge in the sewage has blackening and smelliness phenomena, and produces poisonous and harmful combustible gas.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a jet aeration device, an aeration method and a rainwater storage tank for a rainwater storage tank. Background technique [0002] When a city receives rain, it tends to increase runoff, and rainwater and sewage often converge, increasing the burden on urban drainage and sewage pipe networks. Direct discharge into natural water bodies will cause serious pollution to the water body environment, so it is necessary to add facilities such as primary rain storage tanks to regulate rainwater of different water quality. In my country's urban drainage system, the application of primary rain storage tanks is becoming more and more extensive. [0003] However, after the initial rainwater entering the initial rain storage tank is stored for a period of time, the sludge in the sewage will turn black and smelly, and produce toxic and harmful combustible gases. However, the existing...
