Embodiment Construction

[0014] As shown in Fig. 1 and Fig. 2, the method and device for treating sewage in the present invention transform the scrapped coal mine shaft shaft into a deep aeration shaft for sewage treatment, and add a new aeration shaft in the shaft shaft for sewage treatment after transformation. Isolation steel plate and downpipe 4, riser pipe 5, water inlet pipe 1, head water tank 2, degassing pool 6, outlet pipe 7, sludge return pipe 8 are arranged on the top, and deep well aeration wells are arranged outside the shaft of the mine shaft wall 3.

[0015] The present invention is a technical method and device for treating sewage. Its technological process is as follows: the raw sewage enters the head water tank 2 through the grid and the grit chamber, and after being fully mixed with the return sludge, enters the downcomer 4 in the shaft of the mine shaft. , there is a downward aeration head in the downcomer 4 to oxygenate the circulating water body, the sewage from the shaft of the ...

Abstract

The invention relates to a method and a device for treating sewage. A scrap vertical shaft barrel in a coal mine is modified into an aeration deep well in sewage treatment, the original drainage facilities and intake pipelines are modified into water inlet and outlet systems of a sewage plant, the original coal mining technology managers and technicians are trained to become technical managers and technicians in the sewage treatment, and the technical requirements and management requirements of the deep wall aeration are met. The manpower and material resources are saved, the period of training workers in the sewage plant is shortened, the problem that the workers are laid off because of closure of the coal mine is solved, the social burden is lightened, and the life quality and the happiness index of people are greatly improved.

Description

Technical field [0001] The invention relates to a method and device for treating sewage, in particular to a method for transforming a discarded vertical shaft shaft of a coal mine into an aeration deep well in sewage treatment. Background technique [0002] At present, deep wells are often used as aeration tanks in sewage treatment. Deep well aeration can increase the concentration of dissolved oxygen in the mixed liquid, and is suitable for wastewater treatment with large load changes and high organic concentration. It has the advantages of stable operation and less land occupation. On the other hand, there are coal mine shaft shafts that have been scrapped or are about to be scrapped around many cities, and the traditional processing method is to fill them up and level them. However, the technology of using abandoned coal mine shafts as deep well aeration tanks is a blank. Contents of the invention [0003] In view of the above deficiencies, in order to transform the d...
