However, recycling is the inevitable trend of current sewage treatment development, pollution control and recycling are combined, the contradiction between water supply and demand can be relieved, and pollution to surface water can be relieved. The treatment technology used in China mainly comprises the following steps: precipitation, coagulating sedimentation filtration and the like. The mine water directly discharged after treatment is usually treated by precipitation or coagulating sedimentation; after treatment, the water is used as production water or other water, and a coagulating sedimentation filtration treatment technology is usually adopted; after being treated, the water is used as domestic water, and after being filtered, the water must be subjected to the treatment of removing harmful substances to human bodies such as phenol and the like and disinfection; some mine water containing suspended matters has high salt content, and the mine water after being treated must be further desalted after being purified as drinking water.
Publication No. CN101012091A discloses a method for treating accumulated water in a waste mine, which is particularly suitable for treating mine water containing suspended matters, iron, oil, acidity and high salinity. The method comprises the steps of lifting mine water to the ground through a water pump, putting a certain amount of oxidant, neutralizer and flocculant through a drug pool, injecting the mixture into an underground tunnel, and carrying out flocculation, precipitation and neutralization reactions in an underground specially-made horizontal sedimentation tank to achieve the purpose of removing oil, iron and acid. After the mineral water flows out of the main roadway, the mineral water is pumped to the ground again, part of the supplementary medicament continues to participate in next stage circulation to further improve the water quality, and part of the supplementary medicament is used for supplying water with different purposes after being filtered, electrodialyzed and disinfected, so that the mineral water is finally transited from agricultural water to industrial water and finally to domestic water step by step. The method has the advantages of low investment cost, small land occupation area, simple and convenient facilities and wide application range, and realizes the optimal unification of environmental benefit, social benefit and economic benefit.
The CN101975087A publication relates to mine water comprehensive treatment and utilization technology, which comprises goaf warm water heat exchange utilization, underground Ordovician ash drainage drilling water utilization as underground dustproof water, rock magma drainage drilling water utilization as domestic water, and underground sewage treatment utilization. The method solves the treatment problem of a large number of mines, avoids environmental pollution and saves precious water resources.
The two methods adopt medicine treatment, the treatment speed is low, the underground treatment construction difficulty is high, the cost is high, the construction period is long, and the maintenance is difficult.
