The composite lime powder which prepared from refined sugar filtered mud was used forpreliming and neutralization in sugarcane purification process. pH of preliming process was 6.2~6.4, pH of neutral reaction was 8.3~8.5. Artificial neural network was applied to deal with experimental results, and the low-sulphur and phosphorus-free sugarcane purification process modeling equations was obtained. The optimal conditions were: preliming pH=6.30, 1% polydimethyl diallyl ammonium chloride of the dosage was 6.50mL/L, sodium metabisulfite of the dosage was 1.05g/L, neutralization pH=8.30, 0.1% PAM of the dosage was 3.1mL/L. Results showed that the preparation composite lime powder with refined sugar filtered mud meet the requirement of sugarcane purification process.
