【摘要】 利用生物反应器处理脱墨废水,以煤渣作为吸附载体,将白腐菌菌丝体固定吸附在煤渣表面,底部通入压缩空气,用循环水泵将废水从贮存池连续不断地泵入反应器,在不添加任何外源营养物条件下,脱墨废水有较好的处理效果。在开始运行的前1～3天,废水CODCr下降最快;运行至第4～5天,CODCr降到最低值,为551.8mg·L-1,CODCr去除率最高达75.8%。此后随时间延长,去除率不再增加。最佳曝气量为70L·h-1,反应中随处理时间的变化废水pH值有逐渐升高的趋势,应调节废水的pH值保持在4.0～4.5范围内。从降解前后GC分析可知,废水中的有机污染物质得到一定程度的降解。更多还原

【Abstract】 Using biological reactor,without any extra nutriments,white rot fungus was directly absorbed and fixed up on the surface of cinder which was used as the carrier of sorption.Compressed air was sent into biological reactor by one coniform room which located at the bottom of the reactor.Deinking effluent was continuously transferred from one quadrate reserving pool to the reactor by a small pump.CODCr dropped rapidly during the processing prophase,esp.in the first 1～3 day.At the 4～5 day,CODCr reached the lowest at 551.8mg·L-1 and the highest removal rate of CODCr reached at 75.8%.In the later time the removal rate of CODCr stopped increasing.The best blowing air volume was 70L·h-1.pH value was increasing slowly with the extending HRT,so it should be adjusted and kept in the range of 4.0~4.5 in order to keep the best living condition of white rot fungus.From the analyse of GC,major parts of pollutants in the deinking effluent were degraded.更多还原
