Description
Technical Field
The invention belongs to the technical field of environmental protection, and particularly relates to a system and a method for treating polymetallic associated gold ore beneficiation waste liquid.
Background
In the process of mineral dressing of the polymetallic associated gold ore, a heap leaching method is generally used for primarily separating gold elements from other metal elements (mostly heavy metal elements) or/and impurities in the ore. In the process, a large amount of beneficiation waste liquid (mixed liquid of water, organic solvent and other harmful substances) containing heavy metal elements (such as copper, cadmium, lead, chromium, manganese and the like) and organic substances such as naphthalene, phenol, anthracene, cyanide and the like is generated. If the mineral processing waste liquid is directly discharged into the water body around the mineral processing field without being treated, the environment can be seriously polluted.
Because the beneficiation waste liquid of polymetallic associated gold ore has complex components and contains various harmful substances, ideal waste liquid treatment effect is difficult to achieve by adopting a single method, such as a chemical precipitation method, an adsorption method, an ion exchange method, a nano heavy metal water treatment method and a microorganism treatment method. Generally speaking, it is only possible to achieve ideal waste liquid treatment effect by using a plurality of methods and using more complicated and expensive waste liquid treatment equipment. However, small and medium-sized polymetallic associated gold ores, especially small polymetallic associated gold ores, are limited by economic strength, and complex and expensive waste liquid treatment equipment is rarely used for comprehensively treating mineral dressing waste liquid.
Recently, the company has invented a polymetallic associated gold ore beneficiation wastewater pretreatment apparatus, which comprises a solid-liquid separation device surrounded by a cover body, a side wall and a bottom plate, a crystal separation device surrounded by a cover body, a side wall and a bottom plate (a freezing water pipe penetrates through the cover body, the side wall or the bottom plate of the crystal separation device from the outside of the crystal separation device, enters the inner space of the crystal separation device, extends for a certain distance, and then penetrates out of the cover body, the side wall or the bottom plate of the crystal separation device), an adsorption device surrounded by a cover body, a side wall and a bottom plate, and a water pipe sequentially communicated with the devices. The pretreatment equipment has low cost, can effectively reduce the biotoxicity and the corrosivity of the polymetallic associated gold ore beneficiation waste liquid, and greatly reduce the easy crystallization in the beneficiation waste liquid, but the pretreated waste liquid cannot reach the discharge standard, and the pretreated waste liquid needs to be further treated by combining other methods, such as a microbial treatment method. The microbial treatment method can effectively remove harmful components in the waste liquid to reach the discharge standard, but has the defects of long waste liquid treatment time and low efficiency.

The structural characteristics of the polymetallic associated gold ore beneficiation waste liquid treatment system are described in detail in the above with reference to the accompanying drawings, and the working steps of the invention are further described as follows:
step one, the beneficiation waste liquid containing partial solid debris is pumped into a first water pipe 4 by a water pump, and the first water pipe 4 is vertically communicated with the solid-liquid separation device 1 from top to bottom, and the inertia of the solid debris with the same volume is larger than that of water and an organic solvent, so that most of the solid debris in the beneficiation waste liquid can move downwards and sink to the bottom of the solid-liquid separation device 1, and cannot enter a second water pipe 5 through a bypass pipeline 401 (the situation that a very small amount of the solid debris enters the second water pipe 5 through the bypass pipeline 401 is not eliminated). Due to the diversion effect of the bypass pipeline 401, the flow velocity of the liquid between the water outlet pipeline 101 and the second water pipe 5 is slow, and in addition, the water outlet pipeline 101 is arranged at the upper part of the side wall of the solid-liquid separation device 1, the design is favorable for preventing solid debris in the solid-liquid separation device 1 from entering the adsorption device 3 through the water outlet pipeline 101, the second water pipe 5 and the third water pipe 6.
And step two, in the process of pumping the beneficiation waste liquid, pumping zero-centigrade chilled water into a chilled water pipe 201 in the crystal separation device 2 by using a water pump, wherein due to the action of the chilled water, the inner space of the crystal separation device 2, particularly the periphery of the chilled water pipe 201, forms a local low-temperature area, and after the beneficiation waste liquid after solid-liquid separation enters the crystal separation device 2 from the lower part of the side wall of the crystal separation device 2 through a second water pipe 5, most of organic matters such as naphthalene, phenol, anthracene and the like in the beneficiation waste liquid form crystals and precipitate on the surface of the chilled water pipe or deposit at the bottom of the crystal separation device 2 under the influence of low temperature, so that the beneficiation waste liquid is separated from the beneficiation waste liquid.
Step three, after the mineral separation waste liquid after the crystal separation step enters the adsorption device 3 through the third water pipe 6, the mineral separation waste liquid flows through the first working chamber 301, the second working chamber 302, the third working chamber 303, the fourth working chamber 304 and the fifth working chamber 305 from bottom to top, and then flows out through the fourth water pipe 7, in the process, fine crystal particles and other solid debris which are less in residual in the mineral separation waste liquid can be absorbed by sponge filled in the first working chamber 301, and most heavy metal ions in the mineral separation waste liquid can be adsorbed by the adsorption materials filled in the second working chamber 302, the third working chamber 303, the fourth working chamber 304 and the fifth working chamber 305.
And step four, the beneficiation waste liquid treated in the adsorption step flows into the evaporation tank 12 through the fourth water pipe 7, when the beneficiation waste liquid in the evaporation tank 12 reaches a certain amount, the beneficiation waste liquid is pumped into the water pumping pipe 8 through the water pump, the beneficiation waste liquid enters the water seepage pipe 9 through the water pumping pipe 8, most of the beneficiation waste liquid leaks onto the evaporation cloth 13 through the water seepage holes in the pipe wall of the water seepage pipe 9 and is evaporated into the atmosphere through the evaporation cloth 13, and a small part of the beneficiation waste liquid flows back into the evaporation tank 12 through the water return pipe 10. Under the conveying action of the water pump, the beneficiation wastewater in the evaporation tank 12 continuously circulates, and water in the wastewater is evaporated to the atmosphere through the evaporation cloth 13 (part of water in the evaporation tank 12 is also directly evaporated).
It should be noted that in the plum rain season or the low temperature and humid season, the evaporation effect of the present invention is greatly limited, and therefore, the inventor adopts a technical means that the evaporation tank is connected in series with the biological treatment tank, i.e., the microbial treatment tank is additionally arranged near the ore dressing field, and the wastewater which is not evaporated in the evaporation tank is introduced into the microbial treatment tank by using a water pipe for treatment.
