Description

Technical Field

[0001] The utility model specifically relates to the technical field of wastewater treatment, and specifically relates to a production wastewater softening treatment device. Background Technique

[0002] Gold mine wastewater mainly consists of two parts of wastewater from the mining and ore dressing processes. Its water quality and quantity vary with the nature of the soil and rock in the mining area, the mining method, the production volume, and the season. The main pollutants in the wastewater are suspended substances composed of sediment, clay, humus, and grass roots and bark, followed by organic substances, etc. Although this kind of wastewater has a certain degree of stability, it is not easy to precipitate during the discharge process, making the natural water body turbid and the chromaticity increase. At the same time, it has an impact on and damages the phytoplankton group, zooplankton group, benthic organism group, and fish group in the water ecosystem. The water quality of gold mine wastewater belongs to a multi-stage coarse dispersion system. Its dispersed substances are sediment particles of different particle sizes, and the dispersion medium is water. The formed clay hydrosol colloid is composed of an adsorption layer and a diffuse layer. In the existing wastewater softening treatment process, by a large amount of input of softening agents, the softening effect is not good, and at the same time, the cost of wastewater treatment is increased. In view of the above problems, it is necessary to improve the existing equipment. Summary of the Invention

The filtered wastewater flows into the mixing tank 3 through the delivery pipe 2.

[0030] As Figure 1 and Figure 3 shown, a mixing tank 3 is placed on one side of the sedimentation tank 5. The mixing tank 3 includes a chemical inlet 301. A rotating motor 302 is arranged on one side of the chemical inlet 301. The output end of the rotating motor 302 is fixedly connected to a stirring paddle 303 inside the mixing tank 3.

[0031] In the above solution, a water inlet is opened on the side of the mixing tank 3 close to the filtration tank 1. A through hole is opened at the top of the mixing tank 3, and the chemical inlet 301 is connected at the through hole. The rotating motor 302 is placed on the top of the mixing tank 3, and the rotating motor 302 is connected to the stirring paddle 303 inside the mixing tank 3, facilitating the full mixing of the lime milk and the filtered wastewater in the mixing tank 3.

A filter box 502 is placed at the lower end of the tank body of the sedimentation tank 5. Steel wire ropes 505 are fixed on both sides of the filter box 502, and the other ends of the steel wire ropes 505 are connected to electric winches 504 on a support plate 503.

[0033] In the above solution, the tank cover 501 is rotatably installed on the top of the sedimentation tank 5, and a handle is fixedly installed on the tank cover 501, facilitating the later cleaning of the filter box 502. Support plates 503 are fixedly installed on both sides above the sedimentation tank 5. The electric winches 504 are fixed on the support plates 503. Steel wire ropes 505 are wound on the electric winches 504, and the other ends of the steel wire ropes 505 are fixedly installed at the upper end of the filter box 502. The filter box 502 is driven to lift upward by the electric winches 504 on both sides, separating the flocs in the sedimentation tank 5 from the water through the filter box 502, facilitating the pumping of the sedimented water through the water pump 4 on the delivery pipe 2 at the bottom of the sedimentation tank 5.

[0034] As shown Figure 5 in FIG. 1, on the other side of the precipitation tank 5, a heating tank 7 and a water storage tank 8 are successively arranged. The heating tank 7 includes an electric heater 702. The outer wall of the heating tank 7 is fixedly penetrated with the electric heater 702, and the electric heater 702 is powered by a photovoltaic panel 701 on the top of the heating tank 7.

The wastewater successively passes through the filter layer 102, the activated carbon layer 103 and the resin layer 104 to filter the impurities and calcium and magnesium ions in the wastewater. The filtered wastewater flows into the mixing tank 3 through the delivery pipe 2. Pour lime milk at the medicine inlet 301 in the mixing tank 3, and drive the rotating motor 302 to drive the stirring paddle 303 to rotate to mix the wastewater and lime milk in the mixing tank 3 evenly. Then, through the water pump 4 on the delivery pipe 2 at the lower end of the mixing tank 3, the mixed wastewater is transported to the precipitation tank 5 to wait for precipitation. There are flocs in the precipitated wastewater. Drive the electric winches 504 on both sides. The electric winches 504 wind the steel wire ropes 505. At this time, the filter box 502 drives the flocs to rise upward to separate the flocs from the water quality. Drive the water pump 4 on one side of the water outlet of the precipitation tank 5 to pump the water into the heating tank 7. The electric heater 702 heats and distills the water in the heating tank 7. The generated hot steam enters the water storage tank 8 through the air flow pipe 6. After the hot steam contacts the condensation plate 802, it condenses and falls, and is stored in the water storage tank 8.
