Embodiment Construction

[0014] See figure 1 As shown, an integrated water treatment equipment for coal washing wastewater is mainly composed of a reactor 1, a vertical flow slag removal tank 7, a sedimentation tank 9 and a water purification processor 11. The top of the reactor 1 is provided with a dosing port 2 , a reactor water inlet 3 and a reactor water outlet 4 ; the bottom of the reactor 1 is provided with a reactor slag discharge port 6 . A stirrer 5 is installed in the reactor 1, and the water outlet 4 of the reactor communicates with a vertical flow slag removal tank 7 . The bottom of the vertical flow slag removal tank 7 is provided with a slag discharge port 8 of the slag removal tank. An overflow pipe 18 is installed on the top of the vertical flow slag removal tank 7, which leads directly to the bottom of one end of the settling tank 9. The top of the other end of the settling tank 9 is provided with a settling tank water outlet 12 , and the settling tank water outlet 12 communicates w...

Abstract

The invention relates to integrated treatment equipment for coal washing wastewater. The integrated treatment equipment mainly comprises a reactor, a vertical-flow residue removing tank, a sedimentation tank and a water purifying treater. A medicine feeding port, a reactor water inlet and a reactor water outlet are formed in the top of the reactor. The reactor water outlet communicates with the vertical-flow residue removing tank. A water overflow pipe is mounted at the top end of the residue removing tank and directly penetrates through to the lower part of one end of the sedimentation tank. A sedimentation tank water outlet is formed in the top of the other end of the sedimentation tank and communicates with the water purifying treater. A purified water outlet is formed in the bottom of the water purifying treater. According to the integrated treatment equipment for the coal washing wastewater, the problem of pollution to environments caused by the wastewater resulting from wet-process coal washing is solved, the structure is simple, and the mounting and use are convenient. The flow velocity is high, the precision is high, the filtering area is large, the washing and regeneration are facilitated, the service life is long, and the application range is wide; and the reuse of water resources is facilitated.

Description

technical field [0001] The invention relates to an integrated water treatment equipment for coal washing wastewater, in particular to an integrated water treatment equipment for industrial tail water of a coal mine wet coal washing process. This water treatment equipment solves the SS, COD, sludge, negatively charged fine particles and chroma in the wastewater, and completely avoids the pollution of surface water and groundwater caused by the direct discharge of coal slime water into the external environment. And the treated water can be reused directly. Background technique [0002] Coal washing wastewater is the industrial tail water of coal mine wet coal washing process, which contains a large amount of coal slime and sediment, which has caused serious pollution to the environment near the mining area. Coal washing wastewater is one of the main sources of pollution in the coal industry, and has drawn more and more attention. Coal washing wastewater is particularly stabl...
