The utility model discloses mine water purification treatment device collects reaction, flocculation, sediment, filtration, back flush, arranges mud in an organic whole, including dismantled and assembled particle separation device 1, reaction flocculation device 2 and filtration back flush unit 3, the three highly reduces gradually, and mine water purification treatment relies on water pressure, does not need power. The structure of the utility model is schematically shown in figure 1, and figure 2 is a right view thereof. The particle separation device 1 is communicated with the reaction flocculation device 2 through a water inlet and distribution tank 4, and the reaction flocculation device 2 is communicated with the filtering backwashing device 3 through a filtering and distribution tank 5.

The particle separating device 1 is used for rapid sedimentation of particles in mine water, and the height of the particle separating device is about six meters, which is an ideal particle separating height. The water inlet at the middle part of the device is connected with a pipeline mixer 6, as shown in figure 2, the pipeline mixer 6 is connected with a purifying flocculation dosing device. The lower part of the particle separating device 1 is designed to be a conical surface and is used for receiving sludge, and the bottom of the particle separating device is provided with a sludge discharge port for discharging sludge. For easy maintenance, a manhole is designed at the lower part of the particle separating device 1.

The mine water added with medicine after the large particles are precipitated, namely the raw medicine added water enters the reaction flocculation device 2 from the water inlet and distribution tank 4, as shown in the attached figure 5. The reaction flocculation device 2 is divided into a sludge zone 8, a water distribution zone 9, a flocculation reaction zone 10, a curved pipe settling zone 11 and a clear water zone 12 from bottom to top, and the arrow in the figure is the water flow direction. The raw medicine-added water enters the water distribution area from the water inlet and distribution tank 4 through the water distribution pipe 7, the water distribution pipe 7 is divided into a main water distribution pipe 71 and branch water distribution pipes 72, and the branch water distribution pipes 72 are microporous perforated pipes and are uniformly distributed in the water distribution area to ensure uniform water distribution, as shown in figure 4. Each micropore water flow is sprayed out at a certain flow velocity, as shown in figure 3, turbulence is generated, so that flocculent sludge in the drug-added raw water is fully contacted with fine alum floc, and then the flocculent sludge upwards enters the flocculation reaction zone 10. The dosing raw water is subjected to coagulation reaction under the adsorption effect of the sludge, and the dosing raw water and the sludge have larger contact area through circulating reflux of the residual sludge, so that the coagulation efficiency of the sludge is improved. Thus, the small alum flowers in the raw water added with the medicine are aggregated into larger alum flowers, and favorable conditions are created for the sedimentation of the curved tube.

The curved pipe settling zone 11 is a plurality of S-shaped curved pipes with the height of 1-1.2 meters and is communicated with the flocculation reaction zone 10 and the clear water zone 12 from top to bottom. And a perforated plate 13 is adopted at the bottom of the curved pipe settling zone 11 for water distribution, so that water flow is uniformly distributed. The holes of the perforated plate 13 correspond to the inlet of the curved pipe and no water is available elsewhere to prevent short-circuiting of the water flow into the clean water zone 12 without passing through the curved pipe. When the dosing raw water flows through the curved pipe, the flow velocity is slow, the curved pipe is adopted to promote water flow to generate turbulent flow, and the contact chance among small particle flocs is increased, so that the small particle flocs become large particle flocs, and the effluent quality is further improved. Meanwhile, large particle flocs precipitate downward and enter the sludge zone 8. After sufficient reaction and precipitation, the raw medicine-added water flows upwards along the curved pipe and enters the clear water area 12. An overflow opening 19 is designed at the upper part of the clean water area 12 and is connected with an overflow pipeline.

In order to ensure the sludge discharging thoroughness of the sludge area, the sludge area is divided into a plurality of sludge chambers by inclined partition plates, and the lower part of each sludge chamber is provided with an electric sludge discharging device. The electric sludge discharge device automatically discharges sludge from small chambers one by one according to a set time program, and the sludge discharge time of each chamber in a sludge area is 1-3 min.

The structure of the filtering and backwashing device 3 is shown in figure 3, and comprises a purified water bin 14, a filter material bin 15 and a bottom bin 16 from top to bottom, wherein the arrow in the figure is the water flow direction. The water purifying bin 14 and the filter material bin 15 are separated by steel plates and are not communicated. The filter material bin 15 and the bottom bin 16 are supported and communicated through filter materials, or the filter material bin 15 and the bottom bin 16 are communicated box bodies, and the filter materials are placed in the middle of the box bodies. The filter storage bins 15 can be designed in one or more, separated from each other according to the processing capacity, as shown in fig. 4.

The filtering water distribution tank 5 is communicated with the filtering material bin 15 for water distribution through three U-shaped water seal devices 17, the U-shaped water seal devices 17 penetrate through three bins, namely a water purifying bin 14, a filtering material bin 15 and a bottom bin 16 from top to bottom and then bend upwards to enter the filtering material bin 15, a water outlet is positioned on a filtering material of the filtering material bin 15, an electric butterfly valve 24 is installed at a water inlet of each U-shaped water seal device 17, the electric butterfly valve 24 is normally opened, and the filtering material is closed during backwashing. An inverted U-shaped backwashing pipe 18 is installed at the top of each filter material bin 15, an electric valve 23 is designed on the outlet of the backwashing pipe 18, the electric valve 23 is normally closed, and the filter material is opened during backwashing. The bottom of the filter bin 15 is provided with graded quartz sand as a filter material.

The bottom bin 16 is positioned at the lower part of the filter material bin 15, is communicated with the filter material bin 15 and is communicated with the purified water bin 14 at the upper part of the filtering and backwashing device 3 through a communicating pipe 22. The top of the purified water bin 14 is provided with a vent pipe 21 which is communicated with the atmosphere, the middle part is provided with a water outlet 20, and the treated purified water is discharged from the water outlet 20.

In the normal water treatment state, the electric valve 23 on the backwashing pipe 18 is closed, and the backwashing pipe 18 is filled with water. Clear water flowing out of the clear water area 12 flows automatically to the filter material bin 15 depending on the water pressure of the filtering and distributing tank 5, is filtered by the filter material and then descends to the bottom bin 16, then rises to the clear water bin 14 through the communicating pipe 22, and is discharged through the water outlet 20. When the filter material needs to be washed in the reverse direction, the electric valve 23 is opened, the electric butterfly valve 24 is closed at the same time, water in the backwashing pipe 18 is discharged, a siphoning effect is generated, water at the upper part of the filter material bin 15 is rapidly discharged, and the filter material bin 15 generates negative pressure. The clean water in the clean water bin 14 flows back through the communicating pipe 22, and is discharged through the backwashing pipe 18 after the filter material is backwashed through the filter material bin 15. Thus, the purified water in the purified water bin 14 quickly backflushes the filter material in the filter material bin 15 under the action of static pressure and atmospheric pressure, thereby improving the filtering function of the filter material. Because the electric butterfly valve 24 is closed, clean water in the filtering and distributing tank 5 cannot enter the filtering material bin 15 through the U-shaped water seal 17, and water discharged by the backwashing pipe 18 is all clean water for backwashing the filtering material from the water purifying bin 14. The back-flushing time interval and the back-flushing time can be set on the PLC, and after the filter materials work for a certain time, the filter material bins 15 are back-flushed one by one, so that the filter materials are kept in a good working state. After the backwashing of one filter material bin is finished, the corresponding electric valve 23 is closed, the electric butterfly valve 24 is opened, the mine water treatment is continuously carried out in the device, and the next filter material bin is backwashed after the water purifying bin 14 is filled with water, so that the backwashing of each filter material bin is ensured to have sufficient water, and the phenomenon that the atmosphere enters the bottom bin 16 to destroy the siphon effect is prevented. Even if the atmosphere enters the filter bin, the corresponding electric butterfly valve 24 and the electric valve 23 can be opened at the same time, and the atmosphere is driven out of the filter bin by using clean water. When the filtering effect of the filtering material is not good, water flows out from the overflow port 19 of the clean water tank, the PLC automatically controls the electric butterfly valve 24 to close, the electric valve 23 to open, and the filtering material is backwashed.
