Regulation and storage tank coupled high-load sewage treatment method, device and system

Abstract

The invention relates to a regulation and storage tank coupled high-load sewage treatment method, device and system. The method comprises the following steps: judging the mode of a sewage treatment plant according to pre-acquired water quantity information of the sewage treatment plant; under the condition of an intermittent high-load mode, calculating the volume of a regulation and storage tank and the predicted sewage amount according to the monitoring data; judging the working conditions according to the volume of the regulation and storage tank, the predicted sewage amount and the designedwater amount of the sewage treatment plant; wherein the working conditions comprise a regulation and storage tank water storage working condition and a sewage treatment plant high-load treatment working condition. According to the method, the high-load treatment system of the sewage treatment plant is coupled with the storage pond, the water quantity fluctuation is effectively reduced in sunny days, stable operation of the sewage treatment plant is guaranteed, the treatment potential of end treatment facilities of a drainage system is deeply excavated after rainfall, and interception and purification of pollutants by an end control system of the drainage system are realized to the maximum extent; the maximum benefit of rain and sewage co-treatment measures is exerted, the overflow quantity of a dry season discharge port is strictly controlled, and the rain season overflow pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of water environment treatment, in particular to a method, device and system for treating high-load sewage coupled with a storage tank. Background technique [0002] At present, mixed flow overflow pollution and combined overflow pollution (hereinafter collectively referred to as overflow pollution) caused by mixed connection and wrong connection of urban rainwater and sewage pipes have become one of the main causes of black and odorous urban water bodies and water environment pollution in China. In order to reduce overflow pollution, three technical measures are usually adopted: source, midway and end. Among them, the source measures belong to micro-scale sponge measures, with low-impact development as the core, transforming conventional roofs, roads, green spaces, etc. into green ecological facilities with rainwater infiltration, storage, and purification capabilities, which can effectively reduce regional...

AI Technical Summary

Problems solved by technology

[0003] At present, in the field of terminal treatment of sewage treatment plants, compared with the situation in the south where the water volume is sufficient, the inflow of water from the pipe network in the north fluctuates greatly. The water volume of the treatment plant is set as an intermittent high-load treatment system. This kind of intermittent high-load treatment has a great impact on the sewage treatment plant, and it is difficult to ensure the stable operation of the sewage treatment plant and the stable water output.
