The wastewater from the workshop is firstly separated into solid and liquid by a grit chamber, and the grit of the grit chamber is discharged into the tailings field through the unloading gate. The supernatant liquid overflowing from the grit chamber is mixed and then enters the reactor to fully coagulate the reaction, and then flows into the inclined tube precipitator to further remove fine particles and harmful substances, and the sludge of the inclined tube precipitator passes through the valve. Arranged to the tailings sand field. After passing this process, the wastewater reaches the national allowable discharge standard. According to the requirements of environmental protection, the water from the inclined pipe settler enters the clear water tank, and is returned to the workshop with a clean water pump to save water, and the wastewater is closed in a closed circuit to achieve zero discharge. The process flow is shown below.
