Embodiment 1

[0058] Such as Figure 1-7 As shown, the intelligent sewage treatment expert system device of the present invention includes a data storage device and a display device; the display device is a touch screen display device, or a display device of an external remote control or an input keyboard; the display device can display input The data and data analysis results; wherein the display device can display two first-level modules (ie first-level catalogues), which are respectively an operation management problem query module and a reasoning module for effluent water quality exceeding the standard; the operation management problem query module is provided with sewage Treatment, sludge treatment, biogas treatment purification and disposal utilization, odor treatment, electrical and automatic control, and laboratory testing are six secondary modules ((ie, the secondary catalog)); the reasoning module for the reasons for the effluent quality exceeding the standard consists of 5 Two se...

Embodiment 2

[0093] Embodiment 2: Application of the expert system of the present invention in a sewage treatment plant whose effluent COD exceeds the standard

[0094] The sewage treatment plant is located in East China, with a designed treatment capacity of 40,000 m 3 / d, domestic sewage and industrial wastewater account for 60% and 40% of the influent water respectively, and the types of industries involved mainly include: papermaking, electronics, chemical industry and manufacturing industry. Considering the characteristics of sewage water quality in this area comprehensively, the designed main influent water quality and main control effluent water quality indicators are shown in Table 1 and Table 2. The design process is as Figure 11 shown.

Embodiment 3

[0103] Embodiment 3: Application of the expert system of the present invention in a sewage treatment plant whose effluent TP exceeds the standard

[0104] A sewage treatment plant is located in the Taihu Lake Basin in Jiangsu Province, with a treatment scale of 30,000 m 3 / d, the effluent water quality implements the first grade A standard. The biological treatment process adopts A 2 O+MBR process. Its specific process is as Figure 12 shown.

[0105] The process of the sewage treatment plant is in good condition, and the effluent quality is COD, BOD 5 , TN, NH 3 Both -N and SS can reach the standard stably. 2014.01-2015.06 The influent TP concentration of the sewage treatment plant was between 3-15mg / L, with an average value of about 3mg / L, with large fluctuations. The concentration of TP in the effluent is between 0-1.4mg / L, with an average value of about 0.16mg / L, and about 13% of which exceed the 0.5mg / L required by the Class A standard.

Abstract

The invention discloses an intelligentized sewage treatment expert system, and belongs to the technical field of environmental engineering .The expert system comprises a data storage device and a display device; input data and a data analysis result can be displayed in the display device; the display device can display two first-stage modules including the operating management problem query module and the effluent quality standard exceeding reason reasoning module; the effluent quality standard exceeding reason reasoning module is provided with five second-stage modules including the effluent TN quality standard exceeding reason judging module, the effluent NH3-N quality standard exceeding reason judging module, the effluent COD quality standard exceeding reason judging module, the effluent SS quality standard exceeding reason judging module and the effluent TP quality standard exceeding reason judging module .According to the expert system, sewage treatment field expert-level experience and knowledge are integrated into the same system platform, a more convenient way capable of effectively solving the practical problems is supplied to technicians in the sewage treatment field, checking can be conducted in time, an effective solution can be presented in time, and the operating management level of a sewage treatment plant is increased.

Description

technical field [0001] The invention relates to an intelligent sewage treatment expert system, which belongs to the technical field of environmental engineering. Background technique [0002] Since the reform and opening up, my country's economy has developed rapidly and people's quality of life has been improving day by day, but at the same time the environment has continued to deteriorate, and the water pollution situation is still very severe. As of December 2014, the monitoring data of 968 nationally controlled surface water monitoring sections in 62 key lakes (reservoirs) and 423 major rivers in the country show that 63.1% of them are in Class III (including) and the water quality in Class IV, V and worse than Class V The section still accounts for 36.9%, and the main pollution index is five-day biochemical oxygen demand (BOD 5 ), chemical oxygen demand (COD), total phosphorus (TP) and ammonia nitrogen (NH 3 -N). In the future, with the continuous increase of my coun...
