The application relates to a sewage treatment control method and system based on the MBR process, which belongs to the technical field of sewage treatment. The method includes: determining the MBR based on the preset MBR unit time treatment demand and the unit time treatment capacity of a single MBR membrane. The number of parallel working membranes; according to the specified start-stop time ratio of the MBR membrane and the number of parallel working, a plurality of MBR basic membrane groups are set in the MBR pool, wherein the units of the multiple MBR basic membrane groups The total time processing capacity is greater than the MBR unit time processing requirement; the multiple MBR basic membrane groups are controlled to enter the pause period in turn, and the MBR additional membrane group is set in the MBR pool to replace the suspended MBR basic membrane group to perform MBR processing. By adopting the application, the requirement of starting and stopping the MBR membrane can be met, the service life of the water pump can be improved, and the energy consumption caused by repeated starting and stopping of the water pump can be saved.
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...
