Mine water treatment system

Abstract

The invention discloses a mine water treatment system, and belongs to the technical field of sewage treatment. The treatment system comprises: a pretreatment system; a raw water regulating tank connected with the pretreatment system; a raw water tank connected with the outlet of the raw water regulating tank through a clear water pump; a filter, wherein the water inlet end of the filter is connected with the raw water tank through a raw water pump; an ultrafiltration system connected with the water outlet end of the filter; a primary reverse osmosis system connected with the ultrafiltration system; a secondary reverse osmosis system connected with the primary reverse osmosis system; and a dosing system. Mine water is subjected to advanced treatment by adopting a double-membrane method which mainly comprises ultrafiltration and two-stage reverse osmosis, so the effluent quality standard is high, primary reverse osmosis effluent can be directly used as production water, and secondary reverse osmosis effluent can reach drinking water quality standards, and can be used as source water of mining area domestic water. Compared with treatment systems in the prior art, the treatment systemof the invention can avoid a large amount of waste of water resources and realize the goal of circular economy.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a mine water treatment system. Background technique [0002] Coal accounts for more than half of my country's energy structure. A large amount of wastewater is discharged during coal mining. If it is discharged directly without treatment, it will inevitably cause serious pollution to the environment and cause a large amount of waste of water resources. The goal of circular economy cannot be achieved. Especially with the rapid development of the energy industry in recent years, coal mine wastewater has become one of the important sources of pollution. The coal mine industry is both a major water user and a major pollutant discharger. With the sustainable development of the economy and society and the improvement of people's environmental protection requirements, the requirements for coal mine wastewater treatment are becoming more and more stringent. [0003] The main fe...
