Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for the recycling and treatment of arsenic-containing wastewater. Background Technology

[0002] With the development of industries such as metallurgy and chemicals, as well as the exploitation of low-grade ores, arsenic has been extracted along with other major elements. The amount of arsenic entering wastewater is quite large, and it generally also contains other heavy metal ions. The combined effect of arsenic and lead can make the wastewater more toxic. Arsenic poisoning incidents have been found in wastewater both domestically and internationally. In order to treat large quantities of arsenic-containing wastewater, factories use the activated sludge method to purify the wastewater.

[0003] Publication No. CN214319281U discloses a novel device for recovering arsenic from arsenic-containing wastewater. It achieves the mixing effect by incorporating a stirring mechanism, motor, rotating shaft, U-shaped mixing box, stirring shaft, brush plate, convex cavity A, fixed rod, first support column, long bolt A, nut, and connecting pipe. It also achieves the disassembly effect by incorporating a disassembly mechanism, second support column, filter plate, fixed column, threaded hole, convex cavity B, long bolt B, spring washer, and filter screen. By loosening long bolt B, removing the spring washer, and taking the fixed column out of convex cavity B, the filter screen can be removed. However, this patent still has the following problems in actual use:

[0004] Although this novel equipment for recovering arsenic from arsenic-containing wastewater achieves a stirring effect by incorporating a stirring mechanism, motor, rotating shaft, U-shaped mixing tank, stirring shaft, brush plate, convex cavity A, fixed rod, first support column, long bolt A, nut, and connecting pipe, it cannot achieve the recycling of flocculants when treating arsenic-containing wastewater. Furthermore, the amount of flocculant added during wastewater treatment cannot be guaranteed, resulting in excess flocculant in the wastewater not being recycled and thus wasting it. Additionally, when the amount of flocculant used is insufficient, the arsenic-containing wastewater cannot be adequately treated, affecting the treatment effect.

[0005] Therefore, a wastewater recycling treatment device for arsenic-containing wastewater is proposed to solve the problems mentioned above. Utility Model Content
