摘　　要：在完成了白腐菌培养的优化条件、系统进行了白腐菌处理碱法草浆含氯漂白废水的实验室试验的基础上,进入工厂废水处理现场,自行设计安装了一套以不锈钢丝为载体、用白腐菌挂膜的生物接触中试反应器,在国内建立了第一个白腐菌处理碱法草浆废液的工厂现场中试基地.中试结果表明,白腐菌对氯漂碱法草浆废水有良好的净化效果.中试系统对碱法草浆废水COD去除率为73.0 %～92.2 %,BOD去除率为90.5 %～96.5 %.当水力停留时间(HRT)为24 h时,废水只需经白腐菌一步生物处理,COD≤450 mg/L,BOD≤100 mg/L,SS≤100 mg/L,主要指标达到GB 3544-2001国家标准.当HRT为5～10 h时,经白腐菌反应器处理再加后续活性污泥法、混凝处理,排放废水各项水质指标均可达到国家标准.The study on treatment of waste water of straw alkali pulp by white rot fungi has been made systemically in laboratory, the optimization conditions of white rot fungi culture have been given, and the relevant pilot-scale equipment of white-rot fungi treatment has been setup first in China. A reactor was used, using stainless steel wire as carrier for bio-film of white-rot fungi. The result of pilot-scale experiment showed that the removal rate of COD of straw pulping waste water is 73% -[KG-*6] 92.2% ,the removal rate of BOD is 90.5% -[KG-*6] 97. 8% , when hydraulic reserved time (HRT) is 24h .The quality of discharged water, by only white-rot fungi bio-treatment was:COD≤ 450mg/L ,BOD≤ 100mg/L ,SS≤ 100mg/L ,pH value 6-[KG-*6]9, which meet the requirement of the national standard (GB 3544-2001).
