Abstract :
The bleaching process of wheat straw was studied. NaHSO3 as bleaching main agent, selected concentration, temperature, ultrasonic frequency, time mainly on the factor orthogonal experiment, borrow SPSS13.0 software for statistical analysis, the impact factor on the process factors were optimized by the range analysis and variance analysis, determine suitable wheat straw bleaching optimum process parameters and confirmatory testing. The results showed that: NaHSO3 significant bleaching of wheat straw; The optimum process parameters: concentration 3 %, temperature 40 °C, frequency 45 KHz, time 60min.
