Benefits of technology

This technology helps solve problems with producing low levels (<0) of gallium from high concentrations found naturally occurring deposits such as bismuth oxide ore. By utilizing this process combined different techniques like primary filtering, mixing for better separation results, and multi-adsorbents filters, it can achieve stable production without increasing environmental concerns associated with extraction methods.

Problems solved by technology

This patents discuss two technical problem: how to safely extract valuable metaliuite (thalebore) while minimizing its impact upon both natural environments like lakes and aquatic ecosystems that support biodiversity; and what can be done if there were no significant amounts left behind for this purpose without causing damage to wildlife.

Embodiment 1

[0029] like figure 1 As shown in the figure, a device for treating thallium-containing wastewater in non-ferrous metal smelting according to the present invention includes a first-stage liquid cleaning device 1, a second-stage liquid cleaning device 13 and a third-stage liquid cleaning device 22. The top is respectively provided with a sodium sulfide inlet 2 and a flocculant inlet 3 for adding sodium sulfide and flocculant, a sewage inlet 4 is provided on the top side of the upper top of the first section of the liquid cleaning device 1, and on the inner cavity wall of the first section of the liquid cleaning device 1 An anti-rotation baffle 5 is provided. Since the water flow is required to generate intense turbulence during the mixing process, the medicine and water can be fully mixed in a relatively fast time. Therefore, the anti-rotation baffle 5 is irregularly arranged in the interior of the first stage of the liquid purification device 1. On the cavity wall, the irregular a

Abstract

The invention relates to the technical field of metal smelting, and aims to provide a device and a method for treating thallium-containing wastewater in non-ferrous metal metallurgy, the device comprises a first-section liquid purifying device, a second-section liquid purifying device and a third-section liquid purifying device, liquid in the first-section liquid purifying device is heated to 40-50 DEG C, sodium sulfide and a flocculating agent are added, the temperature of the liquid in the second-section liquid purifying device is increased to 40-50 DEG C, and the temperature of the liquid in the third-section liquid purifying device is increased to 40-50 DEG C; adding a specific agent and a reducing agent after heating to 50-60 DEG C, adding a specific agent and a reducing agent after heating to 50-60 DEG C, adding a specific agent and a reducing agent after heating to 50-60 DEG C, adding a specific agent and a reducing agent after heating to 50-60 DEG C, adding a second-section purified liquid into a clarification tank for natural precipitation, then adding a third-section liquid purifying device for adsorption purification, and detecting the purified liquid. And discharging the qualified clean liquid from the clean liquid outlet. By adopting the method of combining primary filtration, mixed clarification and multiple adsorption filtration, the problem that the thallium element in the lead-zinc smelting effluent of the ore with higher thallium content cannot stably reach the standard is effectively solved, the environmental risk is reduced, and the harm of thallium enrichment to human health is avoided.
