We may not have a certain understanding of coal water treatment systems, but for people in related industries, they are more familiar with it. It is also a type of sewage treatment system, and what are the main equipment of this system?

Generally, coal mine wastewater is treated by introducing sewage treatment equipment to tackle the problem of wastewater treatment. The sewage treatment equipment is equipped with separate horizontal sedimentation tanks and sand settling tanks, rather than adjusting the pre sedimentation tank. Fully utilized the functions of the horizontal sedimentation tank and the sedimentation tank, respectively. Furthermore, it ensures that the system has strong shock resistance to fluctuations in well water bodies and water flow rates.

The key equipment of the coal gasification plant includes coal powder and coal slurry production and processing equipment: cement ball mill, rod mill, dryer equipment, mixer, crusher, powder mill, box filter press, flotation machine, centrifugal dewatering machine, dust removal equipment, calcination equipment, granulation equipment, mixing equipment, filter slurry equipment, etc. Reflecting equipment: reaction kettle, reaction tank, reaction pot, tube reactor, tank tube reactor, vertical tube reactor, slurry bed tube reactor, closed calcium carbide furnace.

For some coal mine water with high oil content, the use of air flotation equipment and air flotation machine ensures the actual effect of the system in removing raw oil. In addition, it can also remove lighter suspended solids that cannot be removed in the sedimentation tank. Generally, automatic backwashing is used for fast biological filters.

Coal mine wastewater is different from domestic sewage. It has a large change in water flow rate, slightly lower concentration of air pollutants, good biodegradability of wastewater, and low difficulty in solving. Chlorine dioxide disinfection and sterilization is used here because chlorine dioxide disinfection and sterilization are not easy to cause carcinogens such as organic chemical fluorides (THMs). Even if discharged into external water quality, it will not have a negative impact on the safety factor of water quality in the water source protection area.
