Analysis on the Renovation and Expansion of Wangwa Coal Mine Water Treatment Plant Phase Ⅱ
According to the characteristics of the mine water quality of Wangwa coal mine,combined with the present situation of the mine water treatment system and the layout of the mine general plan,the construction scale,workshop and structure of the second phase of the mine water treatment plant are reasonably determined.Adopt heavy medium rate sedimentation+multi-media filter process,supporting dosing system.The sludge discharged by the heavy medium velocity sinking equipment is discharged into the sludge temporary storage tank,and the sludge is discharged into the first-stage sludge concentration press filtration system through the sludge pump.The backwashing water of the multi-medium filter tank flows into the catchment pool,and is discharged into the first-stage regulation tank through the submersible pump.The new water treatment workshop includes heavy intermediate rapid sedimentation integrated equipment,multi-media filter,clear pool,collection pool,sludge temporary storage pool,dosing room,power distribution room,etc.The layout of the pretreatment workshop is compact and reasonable,the workshop space is maximized,and the system processing capacity is increased.After completion and operation,the whole system runs smoothly,and the effluent quality is higher than the design index.
