Device for changing water channel to remove iron and manganese ions in water in forced mode

Abstract

The invention relates to a device for changing a water channel to remove iron and manganese ions in water in a forced mode. The device consists of a water inlet pipe, a water distribution plate, a filter material bed, a water flow resistance plate, a water outlet pipe, a water distribution system and a tank body, and is characterized in that the top end of the filter tank is connected with the water inlet pipe; the water distribution plate is positioned in the filter tank; the water distribution plate is horizontally centered and is arranged at the lower end of the water inlet pipe; the filter material bed is positioned at the middle section in the filter tank; the water flow resistance plate is arranged on two sides of the inner wall of the filter tank; the water distribution system is positioned below the filter material bed in the filter tank; and the water outlet pipe is connected to the bottom of the filter tank. The structure in the filter tank is changed, and the water channel is changed in a forced mode, so that the water flow is uniformly filled with the whole filter material, the filter material is fully utilized, the water distribution plate is flushed through hydraulic power, the potential energy of the water flow is reduced, and the direct impact of the water flow on the lower filter material is reduced; and due to the water flow resistance plate on the tank wall, the water flow in the filter can be uniform in water distribution, the resistance of each point in the plane is balanced, the removal rate of iron and manganese is improved, and the stable operation of the filter tank is not influenced.

Description

technical field [0001] The invention relates to a device for forcibly changing water channels to remove iron and manganese ions in water, which belongs to the technical field of water treatment and is used for removing iron and manganese ions in groundwater. Background technique [0002] With the development of economy and the acceleration of urbanization process, the shortage of water resources has attracted people's attention, and the shortage of water resources has become one of the bottlenecks restricting my country's economic development. There are 331 million people in areas where the iron and manganese content exceeds the drinking water standard in China, and the water volume accounts for more than 20% of the total groundwater storage. It is imperative to make full use of this part of groundwater resources to make it into high-quality water. The existing groundwater iron and manganese removal processes and equipment at home and abroad are technically backward, unstabl...

AI Technical Summary

Problems solved by technology

Further research found that the water flow near the wall of the filter cylinder, due to the short flow path and low resistance, easily penetrates the filter material, resulting in a short flow; and the filter material in the middle of the filter fails to fully play the role of intercepting iron and manganese.
