Abstract

The invention relates to a porous composite material applied to liquid pollution treatment and a preparation method thereof. The porous composite material comprises a porous base body and a functional molecular layer covering the inner and outer surfaces of the porous base body, wherein the porous base body is prepared by adopting processes of mixing inorganic materials with organic materials, forming, drying and sintering; the functional molecular layer is prepared by performing acid activation on the porous base body and treating with silane coupling agents with different functions or other organic molecules in a solution. The porous composite material has the characteristics of high selectivity and adsorption capacity on pollutants, good chemical stability and easiness in washing, can be widely applied to the industries of industrial wastewater treatment, mine smelting, electroplating, electronic production and printing and dyeing, and is especially suitable for deeply treating low-concentration wastewater containing the pollutants (such as heavy metal, organic toxin, waste oil or the like) to enable the content of the pollutants in the treated wastewater to reach the standards of domestic drinking water.

Description

technical field [0001] The invention relates to a porous composite material used in liquid pollution treatment and a preparation method thereof. Background technique [0002] With the advent of the global post-industrialization era, the contradiction between the deterioration of the global environment and social and economic development has become increasingly acute. Human beings are willing to pollute the environment at the cost of their own economic development, and the water pollution is serious. Although our country has invested huge funds and technologies in the prevention and treatment of various environmental pollution after years of efforts, the overall deterioration of the environment has not been effectively curbed, and for a long period of time in the future, our country will still face environmental pollution. outstanding issues. At present, traditional wastewater treatment methods include physical-chemical treatment methods, biological treatment methods and adv...
