Abstract

The invention discloses a nanometer composite filter material capable of killing bacteria and removing heavy metal in water.According to the technical scheme, A, seaweed mud, E33 and zeolite powder are mixed and ground; B, a mixture obtained in the step A is evenly stirred and mixed with activated carbon, and water is added; C, high temperature firing is conducted; D, a product prepared in the step C is mixed with nanometer titanium dioxide to obtain the nanometer composite filter material.The nanometer composite filter material has extremely strong adsorption capacity, heavy metal in water can be removed, and the bacterium killing performance is good; the nanometer composite filter material is safe, free of toxin and free of secondary pollution and can be used for purifying drinking water or sewage.

Description

technical field [0001] The invention relates to a method for preparing a nanocomposite filter material, which belongs to the field of water treatment agents. Background technique [0002] Water purifiers can improve water quality and bring great benefits to people's lives and health. However, water purifiers should also be equipped with good water purification filter materials. The adsorption capacity of filter materials is directly related to the filtering effect. [0003] Water purification filter material, including: fiber ball, fruit shell filter material, selected anthracite filter material, refined quartz sand filter material, magnetite filter material, manganese sand filter material, limestone filter material, ceramsite filter material, pebble, zeolite , garnet, medical stone, corundum, rare earth porcelain sand, activated alumina, coconut shell activated carbon, fruit shell activated carbon, wood powder activated carbon, coal-based columnar activated carbon, coal-bas...
