Method and system for operation control of sewage treatment plant
The present disclosure relates to a sewage treatment plant operation control method and system. The operation control method applied to a sewage treatment system comprises: obtaining a functional relationship between the settling flux and the sludge concentration of the secondary sedimentation tank; obtaining a first solid flux value corresponding to the settling flux under the current sludge concentration condition of the secondary sedimentation tank according to the functional relationship; obtaining a second solid flux value corresponding to the intersection position of the underflow flux and the overflow flux of the secondary sedimentation tank under the current sludge concentration condition; and controlling the dosing module to start the dosing mode when the second solid flux value is greater than the first solid flux value.

A tension roller group control method and device of a silicon steel cold continuous rolling mill train
The application discloses a tension roller group control method and device of a silicon steel cold continuous rolling mill train, and is applied to the silicon steel cold continuous rolling mill train. The method comprises the following steps: according to the rotating speed of the tension roller group, the current given value of each tension roller in the tension roller group is corrected in real time, so as to balance the load of each tension roller; during a preset time period when the coiler performs slitting operation, according to the strip linear velocity at the outlet of the last stand and the rolling speed of the last stand, the rotating speed of the tension roller group is corrected; wherein the last stand is the last stand of the rolling mill train; if the roller body slip phenomenon occurs in the tension roller group, the current given value of the slip roller at the slip moment is locked, and the slip phenomenon disappears until the slip phenomenon disappears. The method cooperates from three dimensions of load balancing, slitting disturbance inhibition and slip control, comprehensively improves the running stability and load balancing of the tension roller group under various working conditions, and effectively avoids the over flow, strip breakage and product quality defects caused by the abnormal running of the tension roller.

A nucleogranulation device and its operation method
ActiveCN118598309BReasonable structureSmall footprintWater/sewage treatment by flocculation/precipitationAxial-flow pumpSludge
This invention discloses a nucleogranulation device and its operating method, comprising an annular water distribution pipe installed below a tank, a sludge pipe installed on the tank at the bottom of the annular water distribution pipe, and a granulation reaction zone, a concentration zone, a separation zone, an inclined plate clarification zone, and an overflow trough arranged sequentially from bottom to top above the annular water distribution pipe. A packing device is installed in the separation zone; a drain outlet is provided on the overflow trough; a hollow barrel is located at the center of the granulation reaction zone, and an axial flow pump is installed inside the hollow barrel. The axial flow pump is used to pump part of the water in the concentration zone into the central hollow barrel and transport it to the center of the annular water distribution pipe, with the hollow barrel located directly above the annular water distribution pipe. A water flow disperser is installed at the bottom of the annular water distribution pipe. This invention can increase the operating load, increase the treatment depth, effectively improve the operating load and sludge concentration effect, and the discharged sludge can be directly dewatered, thus improving the effluent quality.
