Method and system for controlling aeration biofilter of sewage treatment plant

Abstract

The invention discloses a method for controlling an aeration biofilter of a sewage treatment plant. The method comprises the following steps of: S1, after performing data reconciliation and data mining on water quality index data by a data analysis module, transmitting the data to an intelligent control module; S2, generating an optimizing strategy by the intelligent control module, and transmitting the optimizing strategy to a control command module; S3, translating to form a control command by the control command module, and sending the control command to a control device; S4, controlling running equipment by the control device, and sending a detection signal to detection equipment by the running equipment; and S5, acquiring new water quality index data by the detection equipment, transmitting the new water quality index data to a historical data operating module and a data analysis module, and returning the step S1. The invention also discloses a system for implementing the method for controlling the aeration biofilter of the sewage treatment plant. The method and the system for controlling the aeration biofilter of the sewage treatment plant are regulated according to requirements, have a stable process, save energy and reduce consumption and are low in manual control cost.

Description

technical field [0001] The invention relates to the field of sewage treatment, and more specifically, relates to a control method and system for a biological aerated filter in a sewage treatment plant. Background technique [0002] At present, most sewage treatment plants in China adopt traditional technology, and there are few detection instruments and control equipment. There are various problems in operation management and operation control, such as: [0003] 1. Various types and different levels of system control methods coexist, which is not convenient for unified management and maintenance. There are even a large number of local manual methods, and the control methods are chaotic; [0004] 2. Although a large number of various testing instruments and water quality analysis instruments are used, a large amount of monitoring data from online instruments are not really used effectively, so that the automatic control system cannot be accurately adjusted and controlled acco...
