Description

Technical Field

[0001] The invention relates to the field of wastewater treatment, and in particular to a mining and dressing wastewater treatment system. Background Art

[0002] In the nonferrous metal industry, a large amount of wastewater is generated in the entire production process from mining, ore dressing, smelting to product processing. The wastewater generated in the ore dressing process is large in volume, complex in water quality, and contains a variety of pollutants. If it is directly discharged, it will cause serious harm to the surrounding environment. If it is returned to the ore dressing process, it will affect the ore dressing indicators.

[0003] The common treatment method at present is to add various reagents to the wastewater and then stir it to make it fully react to achieve the purification of the wastewater. The disadvantages of this method are: the reagents are added in a relatively static manner at one time, which will affect the sufficiency and uniformity of mixing with the wastewater, and thus affect the efficiency and effect of wastewater treatment; in addition, a stirring mechanism is required, which is not conducive to reducing costs. Summary of the invention

[0006] Furthermore, it also includes a plate and frame filter press, and a slag water outlet is arranged at the bottom of the treatment cylinder, and the slag water outlet is connected to the plate and frame filter press through a slag water pipeline, and a pumping pump and a first valve are arranged on the slag water pipeline.

[0007] Furthermore, a circulation pipeline is branched and connected to the slag water pipeline, the circulation pipeline is communicated with the top of the treatment cylinder, and a second valve is arranged on the circulation pipeline; a monitoring meter is installed on the treatment cylinder.

[0008] Furthermore, it also includes a water outlet pool, and the water outlet of the plate and frame filter press is connected to the water outlet pool through a water outlet pipeline.

[0009] Furthermore, a water distribution plate is installed at the outlet of the water inlet pipe, and water distribution holes are evenly opened on the water distribution plate.

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1 As shown, this embodiment discloses a mining wastewater treatment system, including a treatment cylinder 2, a plate and frame filter press 15, a water outlet pool 16, a water inlet pipe 1 and a reagent adding pipe 4, wherein an impeller shaft 8 is rotatably installed across the treatment cylinder, and both ends of the impeller shaft are rotatably assembled with the corresponding side walls of the treatment cylinder respectively, an impeller 9 is fixedly installed on the impeller shaft, and the outlet of the water inlet pipe is above the impeller; the reagent adding pipe extends into the treatment cylinder, and an elastic button valve 5 is arranged on the reagent adding pipe, and a cam 7 is fixedly installed on the impeller shaft, and the cam intermittently squeezes the elastic button valve as the impeller shaft rotates, thereby realizing intermittent opening and closing of the elastic button valve.

[0017] A slag water outlet is provided at the bottom of the treatment cylinder, and the slag water outlet is connected to the plate and frame filter press through a slag water pipeline 10 , and a pumping pump 11 and a first valve 12 are provided on the slag water pipeline.

[0018] The slag water pipeline is branched and connected with a circulation pipeline 14, which is connected with the top of the treatment cylinder, and a second valve 13 is arranged on the circulation pipeline; a monitoring meter is installed on the treatment cylinder, and the monitoring meter is used to monitor pH and ORP values.

[0019] The water outlet of the plate and frame filter press is communicated with the water outlet pool through a water outlet pipeline.

[0020] The specific treatment process is: configure the reagent so that it flows into the treatment barrel from the reagent addition pipe, and wastewater flows in from the water inlet pipe. The water flow impacts the impeller, driving the impeller and the impeller shaft to rotate synchronously. On the one hand, the rotation of the impeller can break up the water flow, and on the other hand, the rotation of the impeller shaft will drive the cam to rotate synchronously, thereby realizing the intermittent opening and closing of the elastic button valve, so that the reagent is intermittently added to the wastewater, which is beneficial to improve the sufficiency and uniformity of the mixing of the reagent and the wastewater, thereby improving the efficiency and effect of mining wastewater treatment, and at the same time, reducing costs.

[0021] During the reaction process, open the pumping pump and the second valve, close the first valve, and allow the reaction liquid to circulate, which is further beneficial to improve the adequacy of the reaction; judge the end point of the reaction through the monitoring meter, when the pH value is between 6-7 and the ORP value is between 100-250mv; close the second valve, open the first valve, and the remaining slag-water mixture in the treatment cylinder is pumped into the plate and frame filter press for filtration, and the effluent enters the effluent pool. The slag sample sludge after filtration is sent to the hazardous waste management center for treatment.

[0022] As a further improvement to the above technical solution, a water distribution plate 3 is installed at the outlet of the water inlet pipe, and water distribution holes are evenly opened on the water distribution plate. The water distribution through the water distribution plate can further improve the dispersion of the incoming water, which is conducive to its full mixing with the medicine.

[0023] As a further improvement to the above technical solution, the outlet of the reagent adding pipe is provided with a nozzle 6; spraying the reagent through the nozzle can further improve the completeness of mixing of the reagent and the wastewater.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
