摘要：In order to explore the removal effect of styrene waste gas by bioscrubber with multi-sided hollow spheres as filler, the residence time, circulating liquid pH and gas-liquid ratio were taken as experimental factors, and the removal rate of styrene was taken as the response value. The experiment was designed according to Box-Behnken, and the response surface analysis method was adopted to establish the corresponding predictive regression model and conduct the analysis of variance. The optimization module of Design-Expert software was used to optimize the optimal combination of all process parameters: the residence time was 43.18 s, the pH of circulating liquid was 7.61, and the gas-liquid ratio was 3.95. Under this condition, the removal rate of styrene was 88.52%. The influence of different fillers on the purification performance of biological tower was compared and analyzed, so as to provide the basis and basis for the application of efficient VOCs processing technology in bioscrubber.
