【Abstract】 The behavior of liquid distributor has significant effect on the purification efficiency of the trickling biofilter. The experiments were conducted to study the performance of a trough distributor and a perforated plate distributor for trickling biofilter. Liquid maldistribution coefficient was introduced to evaluate the performance of liquid distributor. The effects of liquid flow rate, inclination of liquid distributor, and structure of liquid inlet on the liquid malddistribution coefficient were discussed, respectively. The experimental results show that the distributing performance of perforated plate distributor is generally better than that of trough distributor. The trough distributor is applicable to the trickling biofilter for lower liquid flow rate.更多还原
