Embodiment Construction

[0044] The present invention will be further described in conjunction with the accompanying drawings.

[0045] figure 1 It is the operation control flow chart of the sewage treatment lifting pump, such as figure 1 As shown, the optimal scheduling method for sewage treatment lift pumps includes the following steps:

[0046] (1) Determine the maximum and minimum water levels allowed in the sewage tank, the expected operating time of the lift pump, the rated displacement of the high-power lift pump and the rated displacement of the low-power lift pump, and input them to the processing unit;

[0047] (2) Collect liquid level data and transmit the liquid level data to the control unit;

[0048] (3) The control unit transmits the liquid level data to the processing unit;

[0049] (4) The processing unit calculates and processes the liquid level data through the following optimal scheduling algorithm:

[0050] 4a) Calculate the flow of the sewage tank at time k

Abstract

The invention discloses a sewage treatment elevator pump optimized scheduling method, belonging to the technical field of sewage treatment. A processing unit calculates the acquired liquid level data through an optimized scheduling algorithm to obtain the number of large-power elevator pumps and small-power elevator pumps that are needed to be turned on at the present, and feeds back the result to a control unit, and at the end the control unit determines and controls the elevator pumps that are needed to be turned and off. According to the urban electricity pricing policy, the running of the sewage treatment elevator pumps is subjected to optimized scheduling, so that the energy consumption and operation cost of a sewage treatment plant can be reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for optimal dispatching of a sewage treatment lifting pump. Background technique [0002] 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] In the actual production process, the city's electricity charges implement the peak-valley electricity price policy, that is, divide 24 hours a day into two periods, call the 14 hours from 08:00 to 22:00 the peak period, and implement high standard electricity prices, 22: The 10 hours from 01 to 07:59 of the next day are called the valley section, and...
