Problems solved by technology

[0004] However, the existing sewage treatment expert system knowledge base is often constructed for common problems in the sewage treatment process, and sometimes it is difficult to give satisfactory results based on the faults in the sewage treatment process, mainly because of the following three Aspects: (1) The input information is inaccurate and the result is too single
For example, the input information is inaccurate due to the imperfection of the sewage treatment expert system, unclear description of fault phenomena, and many conditions that affect the results given b

Embodiment Construction

[0047] Various example embodiments will now be described more fully with reference to the accompanying drawings, in which some example embodiments are shown.

[0048] The sewage treatment process is a complex process including physical, chemical and biological reactions, often including multiple treatment units to achieve the removal and transformation of various pollutants in different treatment stages. figure 1 It shows the flow chart of the sewage treatment process in the prior art, including an influent sedimentation unit, a hydrolysis acidification unit, a biochemical treatment unit, a dosing disinfection unit and a sludge dehydration unit.

[0049] The sewage entering the sewage treatment plant first passes through the influent sand settling unit, the sewage flows through the coarse grid, and the larger particles of impurities in the water are intercepted, and then the pump in the pump room is lifted to pump the sewage into a pool at a certain height to ensure that the se...

Abstract

The invention provides a sewage disposal fault diagnosis method and device. The method comprises that at least one piece of fault information related to sewage disposal is received; and the at least one piece of fault information is sent to an expert module, and a fault diagnosis result corresponding to each fault information is received from the expert module; or, on the basis of each fault information, a sewage disposal knowledge base, which is established on the basis of one semantic tree corresponding to a technical flow of sewage disposal, is called to determine a fault diagnosis result corresponding to the fault information. According to the sewage disposal fault diagnosis method and device, the fault information can be described accurately, knowledge in the sewage disposal knowledgebase is updated dynamically, online interaction and communication with technical experts are realized, and thus, the proper and effective fault diagnosis result can be obtained.

Description

technical field [0001] The present invention generally relates to the technical field of sewage treatment, and more specifically relates to a sewage treatment fault diagnosis method and device. Background technique [0002] Sewage treatment is a complicated process, and the commonly used tertiary treatment processes include physical methods, biological methods and chemical methods. Affected by residents' life rules, industrial wastewater discharge, climate and geographical conditions, etc., the water quality and water quantity of sewage treatment plants will show certain fluctuations, which makes the sewage treatment process multi-variable, nonlinear, time-varying and uncertain sexual characteristics. Therefore, during the operation of sewage treatment plants, technical management personnel are often required to implement appropriate intervention to ensure the normal operation of the sewage treatment process and make the effluent discharge up to the standard. [0003] At p...
