Intelligent dosing control system based on BP neural network

Abstract

The invention relates to the technical field of sewage treatment, in particular to an intelligent dosing control system based on a BP neural network. The intelligent dosing control system comprises: awater inflow flowmeter for collecting a water inflow value; a tester for total phosphorus in inflow water, wherein the tester is used for collecting a total phosphorus value of the inflow water; an improved ATV phosphorus removal model, wherein the water inflow value and the total phosphorus value of the inflow water are substituted in the improved ATV phosphorus removal model for real-time calculation so as to obtain a dosing trend value and a dosing amount; a tester for total phosphorus in , wherein the tester collects a total phosphorus value of the effluent; a BP neural network adjustmentmodule, wherein the received dosing amount and the total phosphorus value of the effluent are substituted in the BP neural network adjustment module for calculation so as to obtain a dosing amount correction value; a PLC control module, which is used for converting the dosing amount correction value into a corresponding control signal; and a dosing pump, which is used for carrying out dosing according to the control signal. According to an embodiment of the invention, the dosing trend value and the dosing amount are calculated in real time by collecting the water inflow value and the total phosphorus value of the inflow water; the dosing amount and the total phosphorus value of the effluent are substituted in the model for calculation so as to obtain the dosing amount correction value; the system controlled to dose a clarification tank according to the dosing amount correction value; and thus, the phosphorus removal efficiency of inflow water of the clarification tank is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an intelligent dosing control system based on BP neural network. Background technique [0002] In the sewage treatment process of the sewage plant, the process of removing phosphorus by adding drugs is an important process to ensure that the treated sewage can meet the normal discharge standard. Chemical phosphorus removal is usually achieved by adding chemicals to the clarifier. The implementation method is to add polyaluminum chloride PAC to the clarifier to form phosphate precipitation, and then remove phosphorus in the water through mud-water separation, and at the same time assist the addition of flocculant polyacrylamide PAM as needed to enhance the effect of chemical phosphorus removal. Therefore, how to accurately control the amount of dosing and effectively remove phosphorus from the influent of the clarifier is an urgent problem to be solved at present. [00...

AI Technical Summary

Problems solved by technology

[0003] At present, in the sewage treatment process of the sewage plant, the dosing process has the characteristics of hysteresis, nonlinearity, uncertainty, etc., and there are often situations of too much dosing or too little dosing, which cannot guarantee the influent of the high-efficiency clarifier. effective phosphorus removal
