The beneficiation wastewater has large water quantity, contains residual collecting agents, foaming agents, inhibitors, regulators, flocculating agents and the like, has complex water quality components, and forms main pollutants of the beneficiation wastewater by suspended matters, organic pollution, heavy metals and the like. Thus, if untreated beneficiation wastewater is discharged, serious environmental pollution and ecological damage are caused.
The waste water of the traditional tailing pond is discharged after natural clarification. The natural clarification is to use the long-time stay of the wastewater in the tailing pond to carry out natural precipitation, remove most suspended matters and part of heavy metal pollutants in the wastewater through precipitation, and simultaneously generate natural oxidation in the tailing pond to decompose part of organic pollutants.

The method is to add a coagulating sedimentation process on the basis of natural sedimentation to strengthen the removal of heavy metals; and (3) adding advanced oxidation and adsorption filtration to strengthen the removal of organic matters. The organic matter is removed through oxidation and adsorption filtration, so that the influence of residual agents in the wastewater on the beneficiation effect can be reduced as much as possible. However, the Fenton oxidation method, the ozone oxidation method and the like are commonly used for advanced oxidation, and a large amount of ferrous sulfate is needed to be added in the Fenton oxidation method, so that a large amount of iron-containing sludge can be generated, and secondary pollution is caused; the ozone oxidation method is provided with an ozone generating device, and has large investment and high operation and maintenance cost.

To better embody the beneficial effects of the system of the present application, a further description is given by way of a specific embodiment, as follows:
The method comprises the steps of (1) treating waste water of a tailing pond in Yunnan, wherein the main pollutants in the waste water are CODcr 180mg/L, heavy metal Pb 1.60mg/L, zn1.65mg/L, total hardness 1283mg/L, total dissolved solids (representing salt content) TDS20620mg/L and pH6.7 of the waste water, pumping the waste water of the tailing pond into a double-alkali decalcification reaction tank 2 under pressure, adding 20% concentration Na2CO3 solution into the reaction, wherein the adding amount is 5 per mill of inflow water flow, and adding NaOH to adjust the pH within a range of 10.5-11. PAC with 10 percent concentration and PAM with 1.5 per mill concentration are added into the flocculation reaction tank 3, and uniform stirring is carried out in the reaction tank, so that the reagent and pollutants in the wastewater are ensured to fully react. The wastewater enters an inclined tube sedimentation tank 4 for solid-liquid separation, the bottom flow of the sedimentation tank enters a mud storage tank, and the supernatant enters an integrated air floatation device 5. PAC with 10 percent concentration and PAM with 1.5 per mill concentration are added into a reaction tank at the front end of the integrated air floatation device 5, uniform stirring is carried out in the reaction tank, the reagent and pollutants in the wastewater are ensured to fully react, the wastewater enters an air floatation tank for solid-liquid separation, scum is discharged into a mud storage tank 13, and supernatant enters an intermediate water tank 6. The water stored in the middle water tank 6 is pumped into the multi-medium filter 7 by pressure for primary filtration, then enters the activated carbon filter 8 for secondary filtration, and the filtered water enters the filtering water producing tank 9 for storage. Acid is added into the filtering water producing tank 9, and the pH value is regulated to be in the range of 5.5-6.5. The water quality index table of the filtering water producing tank is shown as follows:
The water quality index table of the filtering water producing tank shows that the front-stage treatment of the application can effectively remove hardness, heavy metals and organic matters in the waste water of the tailing pond, the water quality of the filtering water producing tank meets the emission standard of lead and zinc industry (GB 25466-2010), the requirement of process production recycling (low-quality recycling) is met, the treatment cost per ton of water is about 4.5 yuan/m < 3 >, and the treatment cost is lower. The water discharged from the filtering water producing tank is pressurized and enters the DTRO reverse osmosis treatment device for reverse osmosis filtering, and as shown in the table above, the water quality of the water produced by the DTRO reverse osmosis device basically meets the surface water III standard in the surface water environment quality standard (GB 3838-2002), and meets the water quality requirements of high-quality reuse water such as new water supplement of a production water supply system in a factory, preparation water for producing medicaments, greening water in the factory and the like. The comprehensive utilization of the waste water of the tailing pond is effectively realized.
Finally, it is noted that the above-mentioned preferred embodiments are only for illustrating the technical solution of the application, and not for limiting the application, which has been described in detail by means of the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the application.
