Embodiment Construction

[0008] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0009] The present invention uses part of the data in the original PLC automatic control program of the sewage treatment plant: influent water volume, influent COD, influent ammonia nitrogen, DO value of the aerobic pool, and calculates these data in the background to give an optimal operation value. For example, through the adjustment of the total air volume of the blower and the linkage with the flow adjustment valve, the air volume of the biological reaction tank can be distributed and controlled in a timely and accurate manner, so as to meet the demand for stable control of dissolved oxygen, so that each reaction section of the biological tank will not be affected by changes in the water load. It affects its efficient and stable operation; adopting the real-time control principle of ammonia nitrogen feed-forward tr...

Abstract

The invention discloses a novel process controlling system method which can perform artificial intelligence control on sewage treatment. The novel controlling method can imitate artificial intelligence according to water intake variation in waterworks on the basis of established structures, equipment, instruments and technologies in sewage treatment plants, the method being different from manual or automatic control methods. The method is characterized in that the novel process controlling method through artificial intelligence control is provided; an operation module and operation parameter which should be optimized by each process adjustment unit can be calculated for 24 hours according to the water quality changes of a sewage plant; and therefore, indexes like COD, ammonia nitrogen, total nitrogen and total phosphorus can be ensured to reach the standard, and minimum electricity and chemical consumption can be realized. Intelligent control of the open and close and frequency of fans, water pumps and valves can achieve the purposes of optimizing systems, reducing power consumption and enhancing operation stability; and the system can replace most of daily technical management works of sewage treatment engineers, be a management assistant of a large-scale sewage treatment plant, and enhance the technical management level of small and medium-sized 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...
