s1, discharging the waste water generated in the stone processing process into the waste water collecting pool, then filtering the waste water collecting pool, removing large-particle broken stones, and then discharging the broken stones into the sedimentation pool;
s2, presetting the alarm water level in the sedimentation tank:
when the water level in the sedimentation tank is lower than the alarm water level, opening the first electromagnetic valve, closing the second electromagnetic valve, the third electromagnetic valves and the fourth electromagnetic valves, discharging the supernatant in the sedimentation tank into the flocculation tank, adding a flocculating agent, closing the first electromagnetic valve after a period of time, adjusting the pH value of the liquid in the flocculation tank to be neutral through the first acid-base adjusting device, and opening the second electromagnetic valve to discharge the liquid in the flocculation tank into the sedimentation tank;
when the water level in the sedimentation tank is higher than the alarm water level, opening the first electromagnetic valve and the second electromagnetic valve, and primarily adjusting the pH value of the liquid in the flocculation tank through the first acid-base adjusting device; simultaneously closing a plurality of fourth electromagnetic valves, sequentially opening the third electromagnetic valves, sequentially discharging the liquid after the pH value is preliminarily adjusted in the flocculation tank to a plurality of acid-base adjusting tanks, adjusting the pH value of the liquid in the acid-base adjusting tanks to be neutral by the second acid-base adjusting device in each acid-base adjusting tank, and then opening the corresponding fourth electromagnetic valves to discharge the liquid in the flocculation tank to the sedimentation tank;
s3, settling the liquid in the sedimentation tank through the sedimentation tank, discharging the supernatant settled in the sedimentation tank into the filter tank, filtering and discharging into the clear water tank.
9. The recycling method of wastewater from stone processing as claimed in claim 8, further comprising:
s4, sending the sediments at the bottom of the sedimentation tank and the flocculation tank to a separator through a delivery pump, separating the sediments through the separator, discharging the water separated by the separator into the flocculation tank, and delivering the separated solid sludge to a sludge drying tank through a conveyor belt for treatment.
10. The recycling method of wastewater from stone processing as claimed in claim 8, wherein in S3, a coarse sand filter layer, a smokeless coal layer and a gravel layer are sequentially laid in the filter tank from bottom to top to filter the water flowing out of the filter tank.
