Novel comprehensive treatment device for coal mine water

Abstract

The invention provides a novel comprehensive treatment device for coal mine water. The device comprises a coal particle biological aeration system, a ceramic membrane purification system, coal slurrygas mixing and dredging systems and a slurry pressing system; after raw mine water enters the coal slurry aeration system for treatment and sedimentation, supernatant liquid enters the ceramic membrane purification system for purification, concentrated water purified by the ceramic membrane purification system is discharged and enters the coal particle biological aeration system again, then clearwater purified by the ceramic membrane purification system is discharged and enters a clear water pool; coal slurry treated by the coal particle aeration system is settled and mixed with gas in the gas mixing and dredging system of an aeration pool and then enters the slurry pressing system. The device is simple in process and machinery, convenient to maintain, safe and practical, and the use of coagulating agents and the environmental risk brought by chemical agents are avoided.

Description

technical field [0001] The invention relates to a novel coal mine well water comprehensive treatment device. Background technique [0002] According to the requirements of the state and the environmental protection department, in order to protect the environment and control pollution, it is very necessary for national policies, local economic development, and the protection of the ecological balance of river water bodies. Mine water mainly contains SS, COD, BOD and other pollutants. If the wastewater is not treated, it will cause serious pollution to the surrounding environment. The existing mine water treatment process mainly adopts the way of coagulation and sedimentation to treat mine water. Adding a large amount of chemical agents to the existing process is likely to cause chemical pollution to the water body and sediments, and it takes up a large area, high operating costs, unstable water quality, and difficult operation. At the same time, light ceramsite biological T...
