文摘内容 The air microbial species and quantities in a wood mill in Harbin, China were measured using sedimentation plate method. Results showed that the microbial quantity in the air at the workshop without depurator (54939 cfu.m-3) was 2.1 times that of the workshop with depurator (25768 cfu·m^-3). The depurator could purify air microorganisms at the workshop, with a purifying rate of 53.1%, but it did not reach the standards of clean air. Comparatively the depurator is effective in reducing the quantity of air actinomyces, and some kinds of air actinomyces,such as Scabies, Cinereus and Hygroscopicas, can be clean out, but it is not very effective to bacteria and fungi. It is suggested that more effective and feasible methods should be developed for purifying air microorganisms at the workshop in the future。
