Biochemical sludge pre-pretreatment high-concentration wastewater device

The utility model provides a device for pre-treating high-concentration wastewater by biochemical sludge. The device comprises a water collecting tank, adsorption reaction equipment, sludge separation equipment, biochemical treatment equipment and a sedimentation tank which are sequentially communicated through a pipe body, the system further comprises dosing equipment and sludge filter pressing equipment, the dosing equipment is connected with the adsorption reaction equipment through a pipe body, the sludge filter pressing equipment is connected with the sludge separation equipment through a pipe body, and the sedimentation tank is connected to the adsorption reaction equipment through a pipe body. According to the device for pre-treating the high-concentration wastewater by using the biochemical sludge, organic matters and refractory substances in the high-concentration wastewater are adsorbed by using the biochemical sludge generated by treating the high-concentration wastewater, so that the effective tre
