Abstract
The invention discloses a device for removing high-concentration ferro-manganese in mine water with an oxidation and catalysis column and a processing method for eliminating high-concentration ferro-manganese in the mine water with the oxidation and catalysis column. The device consists of a buffer pool, a water intake device, a reaction column, an aerating device, a drain pipe, a sludge discharge pipe, a support and a control system, wherein the bottom of the support is provided with the buffer pool, the reaction column is arranged above the support, the bottom of the buffer pool is connected with the center of the bottom of the reaction column by the water intake device, the center of the upper part of the reaction column is connected with the aerating device, the upper part of the side wall of the reaction column is provided with the drain pipe, the bottom of the reaction column is also provided with the sludge discharge pipe, the control system is arranged on the support, and a water pump in the water intake device is connected with a lead of the control system. The mine water containing high-concentration ferro-manganese and air are mixed in the reaction column and then fully react with a catalysis material in the reaction column, clear water generated in the reaction is discharged from the drain pipe, and the precipitated sludge is discharged from the sludge discharge pipe. According to the device and the processing method, through the aeration and the full contact with the catalysis material, deep processing for the mine water containing high-concentration ferro-manganese can be realized, and the equipment is compact in structure, reasonable in design and small in occupied space and is suitable for processing the mine water containing high-concentration ferro-manganese used for life in various mine lots.
Description
technical field [0001] The invention belongs to the field of mine sewage treatment devices and techniques, in particular to a device for removing high-concentration iron and manganese in mine water by an oxidation catalytic column and a treatment method thereof. Background technique [0002] In many areas of my country, mine water sources, especially in major cities and regions in Northeast China, South China, Central South and Southwest China, have excessive iron and manganese. and industrial production are adversely affected. As early as the early days of the founding of the People's Republic of my country, "groundwater iron and manganese removal" was established in China. Its theory and application have experienced three development stages: natural oxidation method, contact oxidation method and biological method. But so far, how to realize the rapid and efficient removal of iron and manganese is still one of the common problems faced and need to be solved by the conventio...
