Abstract

The invention discloses a water purifying plant for removing brominated trihalomethane and brominated haloacetic acids, which comprises a filter drum and a filter element, wherein the filter element comprises a zeolum layer, a diatomite layer and an active carbon layer, and the diatomite layer is arranged between the zeolum layer and the active carbon layer. Compared with the prior art, the waterpurifying plant for removing brominated trihalomethane and brominated haloacetic acids comprises the filter drum and the filter element, wherein the filter element comprises the zeolum layer, the diatomite layer and the active carbon layer, and the diatomite layer is arranged between the zeolum layer and the active carbon layer, the three layers can have better flocculation and precipitation function, filtration function and synergetic action, and can effectively remove the brominated trihalomethane and the brominated haloacetic acids in water without producing harmful substances of bromate orsilver and the like; the removal rate of the brominated trihalomethane and the brominated haloacetic acids in water can reach up to over 95 percent.

Description

technical field [0001] The invention relates to a water purification device for removing bromotrihalomethane and bromohaloacetic acid in water and a preparation method thereof, belonging to the field of water treatment. Background technique [0002] The rapid development of industry and agriculture has led to serious damage to water resources. Industrial wastewater is discharged into rivers and lakes, pesticides, insecticides, etc. are used in large quantities, and domestic garbage and domestic wastewater are discharged indiscriminately. As a result, many harmful substances are produced in the water. Water pollution has increasingly become a serious problem affecting people's lives. [0003] In many areas, untreated water contains bromide compounds, including bromotrihalomethanes and bromohaloacetic acids. Bromotrihalomethanes and bromohaloacetic acids are considered to have stronger DNA oxidative damage capacity than chloroacetic acid, and are more potentially harmful to ...
