Abstract

The invention discloses a printing and dyeing sewage filter material containing a mesoporous material and a preparation method of the printing and dyeing sewage filter material. The filter material ischaracterized by comprising binchotan fibers, bamboo carbon fibers and a basalt base material part, and through loading the three filter components with a mesoporous molecular sieve, the specific surface area of a filter tip and a micro pore channel are increased. The filter material prepared by the preparation method disclosed by the invention is used for wastewater treatment of a textile printing and dyeing enterprise and has the advantages of being high in decolorizing rate, high in dye and metal ion adsorbability, free from environmental secondary pollution, green, environmentally-friendly and the like; and the preparation method is simple in process and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of filter materials, in particular to a printing and dyeing sewage filter material containing mesoporous materials and a preparation method thereof. Background technique [0002] Textile factories often discharge a large amount of industrial wastewater. The sewage discharged by it contains a high content of organic compounds, a variety of substances, and the color of the sewage is also very obvious. The acidity and alkalinity are unstable, and the quality of the water body is also unstable. . At present, sewage treatment is treated by reverse osmosis membrane, which works well, but the cost is too high. Binchotan fiber is a new type of functional fiber spun by adding nano-sized charcoal particles into viscose or polyester fiber. It has more internal pores and more active active groups than bamboo charcoal fiber, and can absorb and retain a large amount of printing and dyeing sewage. dyes and residues. Mesoporous ma...
