In addition, the whole device has low automation degree, and only utilizes reverse osmosis effluent water, so that the utilization rate of water resources is not high. The patent CN203794713U provides a mine water underground treatment and recycling device, wherein a multi-media filter only carries out sampling and analysis of a water sample through a lower sampling tube to judge whether a filter element needs to be cleaned and replaced, the operation is complicated, and the labor cost is increased; the modularization degree of the whole equipment is not high, and meanwhile, the pH value is not easy to be accurately regulated and controlled, so that the effluent has the risk of exceeding the pH value. CN210030220U provides a modularization reverse osmosis water treatment facilities, this reverse osmosis treatment facilities adopts carbon filter, sand filter, secondary filter etc. as the pretreatment systems before reverse osmosis, and its pretreatment systems's filter fineness is relatively poor, and carbon filter, sand filter area are great, and take place the problem that the filter material leaked easily to make whole water treatment systems's stability reduce. The whole equipment also lacks a safe and reliable control system and a self-cleaning function, is complex to operate and is troublesome to operate and overhaul. And the whole equipment is not beneficial to direction adjustment due to the higher integration level, the water produced by coarse filtration is not effectively utilized, and meanwhile, the waste water reflux treatment is lacked.
Therefore, how to provide an economic and efficient underground modular reverse osmosis treatment and recycling device for mine water, which realizes the maximization of water resource utilization in the water treatment process, is convenient to overhaul, has high integration degree, small volume and is used for automatically controlling operation is a technical problem to be solved urgently by technical personnel in the field.
