Embodiment Construction
[0047] Below in conjunction with accompanying drawing, the present invention will be further described.
[0048] The method of the present invention is to use the liquid level sensor to collect liquid level data and transmit it to the control center, and the control center transmits the data to the processing center to predict the amount of sewage and calculate the optimization algorithm in real time to obtain the number of lift pumps that need to be turned on at the corresponding time. and sent to the control center. The control center determines and controls the lift pumps that need to be turned on and off according to the current opening conditions of the lift pumps. The method for controlling the opening and closing of the lift pump is one of automatic control, manual control or remote control. If there is no need to switch the lift pump, continue to collect liquid level data, and perform optimal scheduling calculations at the next moment.

The invention discloses a sewage treatment lift pump optimization scheduling control method based on incoming water prediction. The method comprises the steps that a prediction model of the incoming sewage amount is established according to historical data of a sewage pool water level database and a local 24-hour precipitation amount database; parameters of a sewage pool are collected, wherein theparameters comprise the maximum water level and the minimum water level allowed by the sewage pool, and the rated displacement, quantity and expected running duration of lift pumps; the current waterlevel of the sewage pool is monitored in real time, and the current water level is utilized to predict the incoming sewage amount in future preset time by establishing the prediction model of the incoming sewage amount; the number of the lift pumps which need to be started at corresponding moments is calculated by utilizing a prediction result. According to the method, a control center intelligently controls the start and stop of the lift pumps, unattended operation of the sewage lift pumps is realized, and the labor cost is reduced.
Description
Technical field: [0001] The present invention relates to the technical field of sewage treatment, in particular to a scheduling control method for lifting pumps in sewage treatment. Background technique: [0002] 1) With the advancement of my country's economic development and urbanization, the demand for urban sewage treatment is increasing. At present, although my country has made great progress in the construction of urban sewage treatment plants, most sewage treatment plants have problems such as low level of automation, underestimation of process management, high energy consumption, and high operation and maintenance costs. [0003] 2) The opening and closing conditions of the sewage lift pump determine the water intake of the sewage treatment system, which has an important impact on the stability and energy consumption of the sewage treatment operation, and the lift pump itself is the second largest after the blower in the sewage treatment system Optimizing the contro...
