Research and Pilot Practice on the Treatment Process of Arsenic Manganese Mine Wastewater
In a mining area in Lhasa,Tibet Autonomous Region,arsenic-containing manganese mine water is generated during the production process.Traditional treatment methods have high costs for treating one ton of water.This study explored the removal effect of manganese and arsenic under different treatment process conditions for this wastewater,aiming to achieve lower wastewater treatment costs.The research shows that biological agents have good removal effects on arsenic under different conditions.After the wastewater is oxidized,the removal effect of biological agents on manganese has been significantly improved,with a cost of 0.3 to 0.5 yuan per ton of water treatment chemicals.Based on this,a pilot test was carried out on site.The results of the pilot test showed that when the arsenic and manganese content in the effluent met the standard,the dosage of the drug could be further reduced,and the treatment cost could be further reduced compared with the laboratory test.
