Mine wastewater treatment equipmentAfter being treated by the mine wastewater treatment equipment (mine sewage treatment equipment), it can be used as production water or domestic water. The production water in the mine mainly includes hydraulic water for underground mining equipment, firefighting dust suppression sprinkler, and deep treatment for drinking water.

1、 The process of treating coal mine wastewater for production use

1The mine wastewater is lifted to the regulating pre settling tank, which is equipped with a gantry scraper. The supernatant is pumped by a first stage lifting pump through a pipeline mixer (with a dosing device in front of the mixer)PAC/PAM）Entering the integrated fully automatic mine wastewater treatment equipment (mine wastewater treatment equipment), the water treated by the mine wastewater treatment equipment (mine wastewater treatment equipment) can be used as production supplementary water or yellow mud grouting water.

2The integrated fully automatic mine wastewater treatment equipment (mine wastewater treatment equipment) is equipped with automatic sludge discharge. The sludge water enters the sludge concentration tank and is then lifted to the centrifugal dewatering machine by the sludge pump. The treated supernatant flows back to the regulating tank and the sludge cake is transported outside.

2、 The process of treating mine wastewater and using it as drinking water

After the above-mentioned wastewater treatment, it is further processed as production water. The integrated fully automatic mine wastewater treatment equipment (mine sewage treatment equipment) discharges the effluent into the intermediate water tank through the fully automatic filter (with a disinfection device in front of the intermediate water tank), and then lifts it through the intermediate water pump to the multi-media filter before entering the ultrafiltration device. After the effluent reaches the ultrafiltration water tank, it is lifted by the booster pump to the security filter and then enters the reverse osmosis device (where the ultrafiltration device and reverse osmosis device are equipped with cleaning devices). In this way, the effluent treated by the mine sewage treatment equipment can be used as drinking water.

3、 The process of treating domestic sewage (mainly flushing and bathing water) into recycled water

1The mechanical grid regulating pool enters the integrated domestic sewage treatment device through the lifting pump, which includesAGrade biochemical poolO

Disinfection equipment is installed after the effluent from the biochemical tank, sedimentation tank, sludge tank, and supporting fan room. If it does not need to be reused, it can be directly discharged. The size of the integrated equipment is designed based on the effluent standard to determine the residence time

2The mechanical grid regulating pool enters the integrated domestic sewage treatment device (includingAGrade biochemical pool

OThe effluent from the biochemical tank, sedimentation tank, sludge tank, and supporting fan room enters the intermediate water tank, which is lifted by the intermediate water pump to the sand filter and then enters the activated carbon filter. After disinfection, it can be used as domestic reuse water (such as flushing toilets, watering plants, etc.)
