Environmentally-friendly adsorption material based on incineration ash and preparation method thereof

Abstract

The invention discloses an environmentally-friendly adsorption material based on incineration ash and a preparation method thereof, and the environmentally-friendly adsorption material comprises the following raw materials by weight: 100-200 parts of the incineration ash, 10-15 parts of a sodium hydroxide solution, 8-12 parts of a citric acid solution and 50-100 parts of bamboo activated carbon powder. The preparation method is as follows: crushing the incineration ash and the modified activated carbon powder by a pulverizer, and sieving; pouring isopropanol into a stirring vessel, and continuously stirring to fully dissolve; filtering the solution; putting the solution into the stirring vessel again, then adding the sodium hydroxide solution, and continuously stirring to fully react; washing with deionizing water, placing in a drying oven for drying; putting into the stirring vessel again, and adding the citric acid solution to carry out neutralization; filtering filter residue, and drying the filter residue to obtain the environmentally-friendly adsorption material. The environmentally-friendly adsorption material has no harm to the environment, does not cause secondary pollution, satisfies the sewage treatment and soil conditioning adsorption, and has high reliability and high practicability.

Description

technical field [0001] The invention relates to the technical field of adsorption material preparation, in particular to an environmentally friendly adsorption material based on incineration ash and a preparation method thereof. Background technique [0002] In recent years, the method of removing heavy metals through the adsorption of living organisms has attracted attention. This method mainly uses hyperaccumulative plants, algae, and microorganisms to have a large adsorption capacity for heavy metals to remove heavy metals in wastewater, but using living organisms to remove heavy metals The treatment of sewage is limited by the biomass and growth characteristics of the organism itself, so this type of method is not suitable for large-scale application so far. [0003] Incineration ash refers to the solid ash produced by the incineration system, which can generally be divided into the following four categories: [0004] (1) Fine slag: fine slag falls from the cracks betwe...
