Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, and more specifically, particularly relates to a groundwater iron and manganese filtering device. Background Art

[0002] In the field of water resources, groundwater, as one of the important water sources, has been widely developed and utilized in many areas; however, groundwater often contains excessive amounts of metal elements such as iron and manganese. Excessive iron and manganese in groundwater will not only affect the sensory properties of water, making the water appear yellow or black and produce odor, but will also deposit in pipes, equipment and appliances, reducing water delivery capacity and shortening the service life of equipment.

[0003] Traditional iron and manganese removal equipment uses waterfall aeration or forced aeration through oxygenation of aeration equipment to oxidize the iron and manganese ions contained in groundwater, and then removes iron and manganese ions from groundwater by filtering through iron and manganese removal filters; however, if the aeration volume of underground raw water is insufficient and the oxidation of iron and manganese ions is incomplete, it will seriously affect the treatment effect of subsequent filtration equipment. Although forced aeration can ensure the complete oxidation of iron and manganese ions, high-intensity aeration will cause incomplete gas-water separation in subsequent filtration equipment, resulting in more gas in the treated water, affecting the subsequent pipeline water supply. At the same time, high-intensity aeration will also increase the power consumption of the aeration equipment. Utility Model Content

[0029] Please refer to Figure 3 and Figure 5 As shown, in order to ensure that the manganese removal filter material layer 21 and the iron removal filter material layer 22 can be efficiently filtered in layers, the filter assembly also includes a first filter material holding plate 23, and a plurality of first fixing blocks 24 are provided on the inner wall of the filter chamber 14, which are used to support and fix the first filter material holding plate 23 located on the upper layer, and the top of the first filter material holding plate 23 is filled with the manganese removal filter material layer 21, and when water flows through this layer, the manganese ions will be effectively removed; below the first filter material holding plate 23, a second filter material holding plate 25 is provided, which is also connected and fixed to the inner wall of the filter chamber 14 through a plurality of second fixing blocks 26, and the top of the second filter material holding plate 25 is paved with the iron removal filter material layer 22, and when water flows through this layer, the iron ions can be purified; a large number of water filter holes 27 are provided on the tops of the first filter material holding plate 23 and the second filter material holding plate 25, and these holes can ensure that the water flow can evenly penetrate each filter material layer to achieve the maximum filtering effect.

[0030] The manganese removal filter layer 21 and the iron removal filter layer 22 are used to treat groundwater containing iron and manganese. Its main principle is to use the catalytic effect of manganese dioxide to oxidize the soluble iron ions Fe2+ and manganese ions Mn2+ in the water into insoluble trivalent iron and tetravalent manganese, thereby removing them from the water by filtration; the task of removing iron and manganese from groundwater is through biological membranes. The iron removal membrane is called an iron-activated filter membrane, and the manganese removal membrane is called a manganese-activated filter membrane.
