【Abstract】 The basic principle of using biological method about purification of CS 2 waste gas containing sulpho-compound is introduced and an approach to purification of CS 2 waste gas in low concentration by using a biological trickling filter is studied. The results of preliminary experiment show that when the bio-filter is operated at the optimum operation conditions (the concentration of CS 2 in influent gas is 100?mg/m 3, the gas flow is 0.1?m 3/h, circulated liquid flow is 20?L/h and pH is 4.0), the removal efficiency of CS 2 can reach 80%. It indicates that biological trickling filters can be used to bio-purify CS 2 waste gas.更多还原
