digging a drainage water channel around the collected coal gangue pile, draining the drainage water channel to a water storage hole along a mountain slope, and allowing the generated wastewater to flow onto a filtering device along the drainage channel; when the water level is higher than the water level sensor, the control system controls the water pump to pump purified water into the water storage tank along the water pipe so as to be utilized; when the water level is at the lowest position of the water level sensor, the control system controls the water pump to stop working.
The technical scheme of the invention has the following beneficial effects:
1. the invention utilizes the slope to set the guide roller in an inclined way, so that the guide roller naturally rolls, and coarse sand, mud blocks, branches and the like which cause the wastewater to flow into the water storage hole are filtered.
2. The invention prevents branches, coarse sand, stones and the like carried by the waste water from flowing into the water storage hole from gaps generated between the filtering device and the water storage hole through the arranged protective cover.
3. The invention can utilize the treated wastewater in time and avoid the water pump idling due to the low water level by the cooperation of the water level sensor and the water pump, thereby realizing automation.
4. The purification layer of the invention adopts limestone as a neutralizer, so that metal ions in the wastewater react with the limestone to precipitate and separate, thereby utilizing the wastewater.
