Problems solved by technology

However, at present, there is little research on arsenic removal technology for geological materials such as rocks and soils, and there is no good technical means to reduce the content of arsenic in geological materials, which is also the technical bottleneck of geological materials used in water mineralization

Abstract

The invention discloses a device for reducing the arsenic content of rock. The device comprises an arsenic removal tank, an arsenic removal pool is formed in the arsenic removal tank, a water arsenic dissolving capacity improving piece is arranged in the arsenic removal tank and is used for improving the arsenic dissolving capacity of water, and a water inlet is formed in the arsenic removal tank. The water inlet and the arsenic removal tank are located on the two sides of the water arsenic dissolving capacity improving piece correspondingly, the rock is contained in the arsenic removal pool, water enters the arsenic removal tank through the water inlet, the arsenic dissolving capacity of the water arsenic dissolving capacity improving piece is improved, then the water enters the arsenic removal pool, and the water makes contact with the rock and dissolves arsenic in the rock. The arsenic removal tank of the device is internally provided with the water arsenic dissolving capacity improving piece, and the water arsenic dissolving capacity improving piece can improve the arsenic dissolving capacity of water, so that arsenic adsorbed on the rock surface is more easily desorbed and migrated into the water. In addition, the invention further provides a method for reducing the arsenic content of the rock.

Description

technical field [0001] The application relates to the technical field of trace element removal, in particular to a device for reducing the arsenic content of rocks and a method for reducing the arsenic content of rocks. Background technique [0002] Water purifiers, also called water purifiers and water purifiers, are water treatment equipment that perform in-depth filtration and purification of water quality according to the requirements for water use. Most of the existing water purifiers use reverse osmosis or nanofiltration technology. These technologies can remove almost all pollutants in drinking water, but they also reduce the content of minerals such as calcium and magnesium in the water while removing pollutants. . Drinking low-mineral water for a long time will make it difficult for people to obtain enough mineral elements to maintain metabolic balance in the body. Therefore, Rosborg et al. proposed that drinking water with low mineralization should be remineralize...
