Embodiment

[0026] Embodiment: a kind of drainage control method of sewage well of sewage treatment plant of this embodiment, such as figure 1 shown, including the following steps:

[0027] S001. The controller obtains the sewage inflow rate through the flowmeter, and the controller obtains the sewage storage in the sewage well through the water level gauge; the water level gauge directly measures the water level height, and then obtains the sewage storage through the product of the cross-sectional area and height (for sewage with a constant cross-sectional area well) or get the sewage storage through the table look-up method (for sewage wells with changing cross-sectional areas);

[0028] S002. According to the average sewage inflow rate Q in the last working period, the controller 1 Determine the number M of pumps that need to be started:

[0029] If the current sewage storage is greater than or equal to the standard storage, then M is If the current sewage storage is less than the ...

Abstract

The invention discloses a drain well drainage control method for a sewage treatment plant. The drainage control method is characterized by comprising the following steps: S001, acquiring a sewage influx rate by virtue of a controller through a flow meter, and acquiring sewage reserves in a drain well by virtue of the controller through a water level indicator; S002, determining the number M of water pumps, which need to be started, by virtue of the controller in accordance with an average sewage influx rate Q1 within the prior working period; S003, starting M water pumps having the minimum priority value by virtue of the controller; and S004, calculating the priority value of each water pump once again after the water pumps work for a working period, and then turning to the step S002. According to the drainage control method provided by the invention, instead of taking a fixed value of the number of the water pumps which need to be started in each stage, the number is dynamically controlled in accordance with the average sewage influx rate, so that a water level in the drain well can be effectively controlled and the entire treatment system can be kept stable, and subsequently, various subsequent treatment lines are balanced in load. The scheme is applicable to all sewage treatment plants.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a drainage control method for sewage wells of sewage treatment plants. Background technique [0002] Sewage treatment is a very important part of environmental governance. Sewage generally includes domestic sewage and industrial sewage. Municipal sewage is usually purified by sewage treatment plants. [0003] After the sewage enters the sewage treatment plant through the pipeline, it is first discharged into the sewage well (or sump), and then pumped into the subsequent treatment pool by the water pump for treatment. Sewage wells are mainly used to collect sewage, which can reduce the impact of flow changes on the treatment system. [0004] Existing sewage wells generally control the work of the water pumps according to the needs of the treatment pool, or start the water pumps in a fixed order, but cannot balance the working hours of the water pumps, and it is easy to make some...
