A method for recycling sewage sludge is provided to surely remove vicious pollutants for a short time through eco-friendly treatment, thereby minimizing environmental pollution due to discharge of the pollutants. Vermiculite or yellow soil stone having pores, which are enlarged by foaming treatment, is processed by electric reaction and laser treatment. Enzyme germs are cultured within the processed vermiculite or yellow soil stone. The cultured enzyme germs are rooted in carriers. The carriers are contained within TiO2 UV photocatalysts, CO2 infrared photocatalysts, and Al2O3 far-infrared photocatalysts, respectively. The photocatalysts are processed by laser treatment. When sewage sludge(1) is contacted with the processed photocatalysts, the sewage sludge is combinatively and instantly reacted with the photocatalysts to be decomposed, purified, sterilized, and deodorized. |
