Technical Field

[0001] The utility model relates to the technical field of gold ore smelting, in particular to a multi-element heavy metal environmental protection treatment device. Background Art

[0002] Heavy metals refer to metallic elements with relatively high density and important chemical activity. They generally have relatively high atomic mass and relatively high atomic number. Heavy metals include various elements such as mercury, lead, cadmium, chromium, thallium, etc. Heavy metals widely exist in natural and artificial environments and can be extracted from natural resources such as rocks, soils, water sources, and ores, and the release and emission of heavy metals can also be caused during industrial activities, mining, smelting, and waste treatment processes. And some heavy metals are potentially toxic and harmful to organisms. When heavy metals enter the ecosystem, they may accumulate in soil, water bodies, and food chains. Long-term exposure or excessive intake of heavy metals may pose hazards to human health and the ecological environment. Therefore, it is crucial to effectively control and manage the emission and exposure of heavy metals. So, the sewage containing multi-element heavy metals generated during the gold ore smelting process needs to be treated before discharge.

[0003] After retrieval, it is found that a typical treatment device in the prior art is, for example, the one with the publication number CN213679870U, a metallurgical sewage treatment device, including a base. A bracket is provided on the upper surface of the base, and the bracket is fixedly connected to the equipment body. A water pump plate is fixedly connected to the upper surface of the base, and the upper surface of the water pump plate is fixedly connected to the bottom end of the water pump. The input end of the water pump is communicated with the left end of the second water suction pipe, and the right end of the second water suction pipe is communicated with the left side wall of the equipment body. The output end of the water pump is communicated with one end of the first water suction pipe, and the other end of the first water suction pipe is communicated with the upper surface of the equipment body. In this metallurgical sewage treatment device, through the cooperation of the provided water pump, second water suction pipe, and first water suction pipe, the sewage precipitated at the bottom of the equipment body can be re-extracted and fully mixed with the reagent, improving the purification efficiency of the sewage. Through the cooperation of the motor, rotating shaft, and stirring roller, the sewage and reagent are fully mixed, improving the stirring efficiency.

[0004] To sum up, when the existing treatment device is in use, after reacting with the reagent, flocs will be generated, and the flocs will be discharged from the discharge port together with the purified sewage, resulting in the need for subsequent separation, increasing the working intensity of the staff, and the treatment method is single, with some heavy metals unable to be removed, reducing the treatment effect.
