Chemical sewage treatment and reuse system

A chemical sewage treatment and reuse system, comprising:

• a raw water tank, a regulation tank pretreatment system, a biological treatment system, an MBR treatment system, and an electrical control system,
• wherein the regulation tank pretreatment system comprises a grating tank, a primary sedimentation tank and a regulation tank which communicate with the raw water tank in sequence;
• the biological treatment system comprises an anaerobic tank group and an aerobic tank group which communicate with the regulation tank in sequence;
• the MBR treatment system comprises a separation tank and a membrane tank which communicate with the aerobic tank group in sequence, the membrane tank communicates with a clarification tank, and the membrane tank and the clarification tank jointly communicate with a sedimentation tank;
• the sedimentation tank communicates with a clear water tank, a discharge tank, an advanced treatment tank and a reused water tank in sequence;
• the electrical control system comprises a plurality of sub-controllers;
• each of the raw water tank, the grating tank, the primary sedimentation tank, the regulation tank, the anaerobic tank group, the aerobic tank group, the separation tank, the membrane tank, the clarification tank, the sedimentation tank, the clean water tank, the discharge tank, the advanced treatment tank and the reused water tank is connected to one of the plurality of sub-controllers;
• and all sub-controllers are connected to a master controller.
