Description

Technical Field

[0001] This disclosure relates to the field of wastewater treatment technology, and in particular to a wastewater treatment control platform. Background Technology

[0002] With increasingly stringent requirements for industrial wastewater treatment, single water treatment technologies are insufficient to meet the dual demands of efficient removal of recalcitrant organic matter and deep denitrification. In-situ coupling of photocatalytic oxidation with MABR technology can simultaneously achieve mineralization of recalcitrant organic matter and efficient denitrification. Specifically, photocatalytic oxidation generates reactive oxygen species that break down recalcitrant organic matter, improving wastewater biodegradability and reducing biotoxicity, thus creating a crucial prerequisite for MABR biological denitrification. MABR technology, with its bubble-free aeration and high oxygen mass transfer efficiency, forms a stratified microbial structure, enabling efficient denitrification through simultaneous nitrification and denitrification.

[0003] However, the coupling system in related technologies uses fixed operating parameters, making it impossible to sense changes in influent water quality in real time. This makes it difficult to accurately monitor changes in key parameters during the reaction process, resulting in difficulties in optimizing photocatalytic conditions (such as light intensity) according to actual needs, and also hindering precise control of the MABR biofilm growth environment. Consequently, the treatment efficiency stability and simultaneous pollutant removal efficiency of the coupling system are severely limited, reducing wastewater treatment effectiveness. Therefore, there is an urgent need for a wastewater treatment control platform capable of real-time sensing and dynamic control to overcome the bottlenecks of photocatalysis-MABR in-situ coupling technology.

[0080] In the embodiments of this disclosure, the method for determining whether the second data, the third data, the fourth data, and the fifth data are continuous can be referred to the detailed description in the above embodiments, and will not be repeated here.

[0081] In this embodiment of the disclosure, the second preset frequency, the third preset frequency, and the fourth preset frequency can be set as needed.

[0082] Step 1019: If the support and self-rotation subsystem, light source and cooling subsystem, effluent subsystem, circulating water subsystem, oxygen supply subsystem, scrubbing subsystem and second online monitoring subsystem are operating normally, then the MABR wastewater treatment system is controlled to operate for a set period based on the first control parameter.

[0083] In this embodiment of the disclosure, the above-mentioned set period can be set as needed, such as 7 days.

[0084] In this embodiment of the disclosure, if there is any abnormal operation in the support and rotation subsystem, the light source and cooling subsystem, the effluent subsystem, the circulating water subsystem, the oxygen supply subsystem, the scrubbing subsystem, and the second online monitoring subsystem, a fault investigation is triggered. After the investigation is passed, the MABR wastewater treatment system is controlled to operate for a set period based on the first control parameter.

[0085] Furthermore, in this embodiment of the disclosure, the method for obtaining corresponding second control parameters by data analysis based on the second key water quality indicator data of the second online monitoring subsystem, and controlling the MABR wastewater treatment system based on the second control parameters, may include the following steps: Step 1021: Based on the second key water quality indicator data of the second online monitoring subsystem, determine the trend of effluent water quality change.

[0086] In this embodiment of the disclosure, the trend of effluent water quality change can be determined based on the second key water quality indicator data of the second online monitoring subsystem at various times. Specifically, in this embodiment of the disclosure, the second key water quality indicator data at any time is compared with the second key water quality indicator data of the previous time. If the second key water quality indicator data at any time is greater than or equal to the second key water quality indicator data of the previous time, the trend of effluent water quality change is determined to be a first trend, that is, a positive trend; if the second key water quality indicator data at any time is less than the second key water quality indicator data of the previous time, the trend of effluent water quality change is determined to be a second trend, that is, a deteriorating trend.

[0087] Step 1022: If the effluent water quality change trend is the first trend, then the first control parameter is determined as the second control parameter, and the MABR wastewater treatment system is controlled based on the second control parameter.

[0088] Step 1023: If the trend of effluent water quality change is the second trend, then the second control parameter is determined based on the microbial attachment status data on the membrane fiber surface and multi-dimensional data.

[0089] In this embodiment, the second control parameter may include the circulation flow ratio, air supply pressure, air supply flow rate, scrubbing flow rate, scrubbing frequency, single scrubbing duration, and light intensity. In this embodiment, the method for determining the second control parameter based on microbial attachment status data and multi-dimensional data on the membrane filament surface can refer to the method for determining the first control parameter described above, and will not be elaborated further in this embodiment.

[0090] Step 1024: Control the MABR wastewater treatment system based on the second control parameter.

[0091] In this embodiment of the disclosure, after controlling the MABR wastewater treatment system based on the second control parameter, it can be determined whether the support and rotation subsystem, the light source and cooling subsystem, the effluent subsystem, the circulating water subsystem, the oxygen supply subsystem, the scrubbing subsystem, and the second online monitoring subsystem are operating normally. If the support and rotation subsystem, the light source and cooling subsystem, the effluent subsystem, the circulating water subsystem, the oxygen supply subsystem, the scrubbing subsystem, and the second online monitoring subsystem are operating normally, then after a preset operating cycle, the above steps 1021 to 1024 are repeated to gradually optimize the control parameters until the effluent water quality stably meets the standards, thus forming an adaptive control closed loop.

[0092] Furthermore, in this embodiment of the disclosure, the control module described above can also be used to perform the following steps: Step 1: Determine whether to start the sewage subsystem.

[0093] In this embodiment of the disclosure, it can be determined whether to activate the sewage discharge subsystem during the above-mentioned start-up biofilm formation stage and enhancement stage.

[0094] In this embodiment of the disclosure, the method for determining whether to start the sewage discharge subsystem may include: determining whether the reactor needs maintenance and / or determining whether impurities are present; if it is determined that the reactor needs maintenance and / or that impurities are present, then determining to start the sewage discharge subsystem.

[0095] Step 2: If you decide to start the sewage subsystem, then determine whether the sewage subsystem is operating normally.

[0096] In this embodiment of the disclosure, the method for determining whether the sewage discharge subsystem is operating normally may include: determining whether the data of the sewage discharge flow sensor is continuous and whether the sewage discharge electric valve is operating at a fifth preset frequency; if the data of the sewage discharge flow sensor is continuous and the sewage discharge electric valve is operating at the fifth preset frequency, then the sewage discharge subsystem is determined to be operating normally; otherwise, the sewage discharge subsystem is determined not to be operating normally.

[0097] Step 3: If it is determined that the sewage discharge subsystem is operating normally, then after the sewage discharge subsystem executes the sewage discharge set cycle, determine whether the sewage discharge stop conditions are met.

[0098] In this embodiment of the disclosure, the above-mentioned sewage discharge setting cycle can be set as needed.

[0099] In this embodiment of the disclosure, the method for determining whether the discharge cessation condition is met may include: after completing a preset discharge cycle (e.g., 5 minutes), measuring the change in suspended solids concentration in the effluent discharged through the discharge system to determine the impurity removal rate; if the impurity removal rate is greater than or equal to the preset removal rate, then the discharge cessation condition is determined to be met; otherwise, the discharge cessation condition is determined not to be met. Specifically, in this embodiment of the disclosure, the impurity removal rate = [(C M1 - C M2 ) / C in ] ×100%, where C M1 C represents the suspended solids concentration at the first time point. M2 This represents the concentration of suspended solids at the second time point.

[0100] Step 4: If it is determined that the sewage discharge cessation conditions are met, then stop the sewage discharge subsystem.

[0101] In this embodiment of the disclosure, if it is determined that the sewage discharge cessation conditions are not met, the sewage discharge subsystem continues to be started until the sewage discharge cessation conditions are met and the sewage discharge subsystem is stopped.
