A new method of intelligent sewage treatment process control (ebis)

Abstract

A new method of process control system for artificial intelligence control of sewage treatment, which is based on the established structures, equipment, instruments and processes of sewage treatment plants, different from manual and automatic adjustment control methods, and imitates manual control according to changes in water intake to water plants Smart new ways to control. The feature of this patent is to provide a brand-new process control method controlled by artificial intelligence. According to the water quality change of the sewage plant, the operating modules and operating parameters that should be optimized for each process adjustment unit of the water plant are calculated 24 hours, so as to ensure COD, ammonia nitrogen, While the total nitrogen, total phosphorus and other indicators are up to the standard, the minimum power and chemical consumption are achieved. Intelligently control the start-stop and frequency of fans, water pumps and valves, so as to achieve the purpose of optimizing the system, reducing power consumption and improving operation stability. At the same time, the system can replace the daily technical management work of most sewage treatment engineers, become a management assistant for large sewage treatment plants, and improve the technical management level of small and medium sewage treatment plants.

Description

technical field [0001] The invention relates to a new artificial intelligence sewage treatment process control method (Energy BiochemicalIntelligent control System, EBIS), which is based on the established structures, equipment, instruments and processes of sewage treatment plants, and is different from manual and automatic adjustment control systems. According to the water inflow changes and inflow and outflow indicators of the water plant imitating artificial intelligence, a new method of operation control that adjusts each unit of the system to the best operating condition by module. [0002] The invention relates to a method of continuously recording and analyzing indicators such as pollutants, flow, and temperature of influent water, in-depth analysis of the water plant treatment process model, determining the delay time and diffusion effect of the impact from the monitoring point to each unit, and optimizing , A new method for automatic adjustment and optimization of pre...

Problems solved by technology

[0003] Although the automatic adjustment control program used by the currently operating sewage treatment plants is to automatically control all the equipment on site, is responsible for the control of the entire sewage treatment process, and will respond to faults, but when the influent water volume changes or the influent water quality When changing, it is impossible to make corresponding adjustments to the aeration rate, return flow rate, chemical dosing rate, and sludge discharge rate in real time. The adjustment is entirely based on the experience of the on-site sewage treatment engineer, and there is a considerable lag.
