摘　　要：利用改性的硅藻土作为载体分别负载白腐菌和好氧反硝化菌对染料废水进行连续式处理,废水的脱色率和CODCr降解率不能同时达到最佳效果;利用改性硅藻土负载混合微生物协同处理染料废水,水处理系统的启动时间为6 d,废水的色度去除率达到70%,CODCr去除率达到63.82%,废水的色度和CODCr能够被同时降低,该方法克服白腐菌仅对染料废水色度降解率高和好氧反硝化菌仅对染料废CODCr降解率高的弊端,扩大了硅藻土和生物水处理技术的应用范围。The white-rot fungi strain F1 or denitrifying bacterial strain H1 was used respectively to treat dye wastewater continuously,which was loaded on by modified diatomite,but the treatment effect of chromaticity removal rate and CODCrremoval rate could not reach the best at the same time. Using of mixed F1 and H1 loaded by modified diatomite to treat dye wastewater,the startup time of water treatment system was 6 d,the removal rates of chromaticity and CODCrof dye wastewater got 70% and 63. 82%respectively,and the two indexes were reduced synchronously. This method overcomes the drawback that white-rot fungi strain could reduce the chromaticity best single and denitrifying bacterial strain could reduce the CODCrbest single,and it expands the application range of diatomite and biological water treatment technology.
