Sewage treatment equipment for coal mine production and process thereof

The invention relates to the field of sewage treatment for coal mine production, in particular to sewage treatment equipment for coal mine production and a process thereof, comprising a treatment box, a water inlet pipe, a tap pipe, a mud outlet pipe, a spray pipe and the like; the treatment box communicates with a water inlet pipe; the treatment box is communicated with a tap pipe; the treatment box is communicated with a sludge outlet pipe; the treatment box is fixedly connected with a plurality of spray pipes. Coal slime water is stirred to flow through the catching net, meanwhile, flocculates are caught through the catching net, then the flocculates attached to the surface of the catching net are shaken off through the U-shaped knocking plate, and then the flocculates are deposited at the bottom in the treatment box, so that the speed of the flocculates depositing at the bottom in the treatment box is increased, and the situation that in the prior art, the flocculates are separated from the bottom in the
