Problems solved by technology

In the 1980s, it began to be used in the field of sewage treatment, but it is still in its infancy in water treatment
Although many scholars have done a lot of research on this in recent years, a set of sewage treatment expert system with good application performance, universally applicable to various water inflow conditions or the whole process control and diagnosis of water plants has not yet been proposed, and domestic Most of the research in this area stays in the theoretical and experimental stage, and there are few cases of practical application

Embodiment 1

[0032] Example 1: The following are the steps to confirm the operation mode

[0033] Step 1: Input the water quality parameters of the influent and the reactor environment parameters, the COD concentration is 190, the NH4+-N concentration is 50, the sludge concentration MLSS is 6100, and the seasonal temperature (T) is 20.

[0034] Step 2: The system matches the input parameters one by one with the 9 pre-stored operating modes according to the system preset parameter range deviation and parameter priority, and finally matches the most reasonable operating mode, and uses the matching results to calculate the process. The actual parameters are displayed to the operator in the same number of ways as the model parameters (e.g. image 3 shown), in order to judge the feasibility of the mode.

[0035] Step 3: If the operator analyzes the matching result and approves it, choose which reactors to assign the final operating parameters to.

[0036] If the operator analyzes the matching...

Embodiment 2

[0039] Step 1: Input the water quality parameters of the influent and the environmental parameters of the reactor, the COD concentration is 190, the NH4+-N concentration is 30, the sludge concentration MLSS is 6100, and the seasonal temperature (T) is 20.

[0040] Step 2: The system matches the input parameters one by one with the 9 pre-stored operating modes according to the system preset parameter range deviation and parameter priority, and finally matches the most reasonable operating mode, and uses the matching results to calculate the process. The actual parameters are displayed to the operator in the same number of ways as the strategy pattern parameters (such as Figure 4 shown), in order to judge the feasibility of the model.

[0041] Step 3: There is no matching pattern in the knowledge base of the expert system, and the operator selects appropriate operating parameters according to the input parameters. Select which reactors to assign the final operating parameters ...

Abstract

The invention discloses a multi-mode optimization-based sewage treatment SBR technological process control expert system, which comprises a human-computer interface, a control cabinet and four SBR sewage treatment reactors, wherein the human-computer interface can realize process monitoring and confirmation of an operation mode, the process monitoring is to display the operation states of the control cabinet and the four SBR sewage treatment reactors in real time, the operation mode is determined to be matched according to water quality parameters of input inlet water and environment parameters of the reactors, the operation mode matched with the system can be selected and used, a new mode can also be manually input, if the new mode runs well, the mode can be supplemented to an expert system knowledge base to continuously improve the system, and the control cabinet of the system can realize automatic and manual control of the SBR sewage treatment reactor. The system can replace human experts to provide a reasonable SBR process sewage treatment operation mode for different inflow water qualities and treatment environments, assist operation management of a sewage treatment plant and improve the operation efficiency of the sewage treatment plant.

Description

technical field [0001] The invention relates to an expert system for SBR process sewage treatment, which belongs to the technical field of environmental engineering. Background technique [0002] In recent years, the domestic water pollution problem has become more and more serious, seriously restricting the sustainable development of my country's social economy. The prevention and control of water pollution has attracted more and more attention from governments at all levels. The number of operational management personnel and the need for experienced technology have also increased. [0003] The expert system was first proposed by E.A. Feigenbaum in the 1960s in combination with a large amount of chemical knowledge. At present, in aerospace, automobile and other general industrial fields, the application has been relatively mature. In the 1980s, it began to be used in the field of sewage treatment, but it is still in its infancy in water treatment. Although many scholars h...
