Abstract

Abstract In order to solve the environmental problems caused by landfilling and incineration of Fenton sludge, realize the recycling of papermaking solid waste. In this paper, we explored the formation of a layer of calcium carbonate coating on the surface of Fenton sludge by crystallization coating in the Fenton sludge-[Ca(OH)2/H2O]-CO2 three-phase reaction system to improve the brightness of Fenton sludge and apply it to the filling of paper. The effects of particle size, temperature, stirring rate and calcium hydroxide addition on crystallization coating effect were studied. The advantages and disadvantages of the coating effect are mainly judged by the brightness and dustiness of the powder material. The research results show that when the particle size is 38–48 μm, the temperature is 25 °C, the stirring speed is 600 r/min, and the ratio of calcium hydroxide to Fenton sludge is 2:1, the brightness of the composite can be increased from 3.56 % ISO to 64.24 % ISO.
