The invention relates to a sewage treatment control method and system based on an MBR process, and belongs to the technical field of sewage treatment, wherein the method comprises the steps: determining the parallel working number of MBR membranes based on a preset MBR unit time treatment demand and the unit time treatment amount of a single MBR membrane; arranging a plurality of MBR basic membrane groups in an MBR pool according to the specified start-stop duration ratio of the MBR membranes and the parallel working number, and the total treatment capacity of the MBR basic membrane groups inunit time is larger than the treatment requirement of the MBR in unit time; and controlling the plurality of MBR basic membrane groups to enter a pause period in turn, and arranging an MBR additionalmembrane group in the MBR pool to replace the pause MBR basic membrane groups to execute MBR treatment. By the adoption of the method and system, the starting and stopping requirements of the MBR membranes can be met, the service life of a water pump can be prolonged, and energy consumption caused by repeated starting and stopping of the water pump is reduced.
Description
technical field [0001] The present application relates to the technical field of sewage treatment, in particular to a sewage treatment control method and system based on an MBR process. Background technique [0002] The MBR process is a new sewage treatment technology that organically combines membrane separation technology and biotechnology. It mainly uses MBR membranes to filter activated sludge and macromolecular organic matter in sewage to solve the problems existing in traditional activated sludge filtration methods. question. [0003] In the sewage treatment process based on the MBR process, the raw sewage water is first introduced into the regulating tank for concentration and flow control, and then the sewage is introduced into the reaction tank, and the sewage treatment agent is added for chemical reaction. After that, the sewage can be introduced into the primary sedimentation tank for sludge precipitation. And the precipitated supernatant is introduced into the b...
