Preparation method of adsorbent for wastewater treatment

Abstract

The invention discloses a preparation method of an adsorbent for wastewater treatment, and belongs to the technical field of wastewater treatment. According to the preparation method, fly ash is subjected to acid leaching treatment, the adsorption capability of the fly ash to dye can be significantly enhanced, chitosan is adopted to be composited with the fly ash, the fly ash is adsorbed on the surface of the chitosan in the compositing process, the electrical property of the surface of the fly ash is changed, dye wastewater is generally negatively charged, in this way, the fly ash has the surface adsorption capability, the treatment effect of wastewater is enhanced, strontium carbonate extracted from celestite is doped in the fly ash, the strontium carbonate can make titanium dioxide lattices distorted, thus an energy gap of a titanium dioxide forbidden band is narrowed, titanium dioxide can absorb light with the wider-scope wavelength, a culture matrix containing bacillus natto liquid is prepared from soybean powder and is rich in gamma-polyglutamic acid, the space reserved after the gamma-polyglutamic acid is biodegraded provides the space for subsequent microorganism growth, the number of the active microorganisms on the adsorbent is increased, and thus the biofilm culturing amount of the adsorbent microorganisms is increased.

AI Technical Summary

Benefits of technology

This patented technology relates to a new type of chemical called strontum carbonate (SCO) that helps break down harmful substances into smaller particles more efficiently than traditional methods like adding iron or aluminum oxides alone. It was found effective at reducing various types of contaminations such as pesticides, metals, dyes, explosives, nitrogen compounds, pharmaceutical agents, and other materials.

Problems solved by technology

This patented describes different types of materials called dyers' detergents (DDS) such as quaternary ammonium salt compounds like DYELLOX®, DOCARBOXYLONES™, polyoxyethylene diamine polymer(PED), polysilane resin, carboxymethylethanes, chlorophyll salts, cyanobacteria algae, and others. These substances have negative impact on human health because their presence affects the environment negatively while causing damage to aquatic ecosystems. Existing techniques involve expensive and time-consuming processes involving complicated steps and disposable products made up mostly of synthetic agents.
