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.

The invention discloses ceramic glaze applicable to a robot glaze spraying process and a preparation method of the ceramic glaze applicable to the robot glaze spraying process. The glaze is prepared from 40-50 parts of kaolin, 30-40 parts of clay, 5-7 parts of cerusite, 2-4 parts of borax, 0.5-0.7 part of yttrium oxide, 4-6 parts of zirconium silicate, 3-6 parts of perovskite, 15-20 parts of quartz stone, 14-17 parts of field soil, 0.5-1 part of galena, 7-9 parts of pyrite and 1-2 parts of celestite. The preparation method includes: dissolving yttrium oxide, zirconium silicate, perovskite, galena and pyrite into acid, adding water to dilute, and keeping for standby application; adding surfactants, and stirring to keep for standby application; adding residual materials into a ball mill, adding solution, and performing ball milling to obtain 150-250-mesh ceramic glaze applicable to the robot glaze spraying process. The glaze is applicable to robot spraying and high in stability. The preparation method is suitable for large-scale industrial application.
