摘　　要：研究了不同的固定化方式、吸附载体及载体体积对吸附法固定化白腐真菌去除苯酚和COD的影响。结果表明,直接吸附效果较佳,16 h时苯酚去除率达到100%、COD去除率约为97%;稻草粉末、棉花秆粉末、麸皮、花生壳粉末、木屑、玉米芯、丝瓜囊、活性炭等载体中丝瓜囊效果最佳,15 h时苯酚去除率为100%、COD去除率约为96%;载体体积对COD和苯酚的去除率影响不同,粉末状花生壳在提高苯酚去除率的同时会降低COD去除率。The methods of immobilization, the carriers and the size of carrier which were used to immobilize white rot fungus were studied by comparing removal rate of COD and phenol. The results indicated that the direct adsorption method was better,with the COD removal rate about 97% and the phenol removal rate 100% after 16 h; vegetable sponge was the best carrier compared with the others, with the COD removal rate about 96% and the phenol removal rate 100% after 15 h. The effects of the size of carrier on the removal rate of COD and phenol were different. The phenol removal rate was higher while the COD removal rate was lower when the wastewater was degraded by dusty carrier instead of shell.
