摘要
介绍了两种采用相同比表面积的不同塑料介质的下流式厌氧过滤器处理精加工废水。交叉流设计的模块化塑料介质的COD去除率分别为80%和75%，负荷分别为8和10 kg /m3天。随着负荷从0.6 kg/m3 d逐渐增加到6 kg/m3 d，膜环介质的COD去除率从90%逐渐下降到57%。与其他高速率厌氧反应器UAF、UASB和AFB相比，下流式厌氧过滤器的性能较低。
A note on anaerobic treatment of currant-finishing wastewater in downflow anaerobic filters and the effect of media design on their performance
Two downflow anaerobic filters with different plastic media of the same specific surface area, treating currant-finishing wastewater are described. COD removal for modular plastic media with a cross-flow design was 80% and 75% for loadings of 8 and 10 kg COD/m3 day respectively. COD removal for pall-rings media gradually decreased from 90% to 57% as loadings gradually increased from 0·6 to 6 kg/m3 day. The downflow anaerobic filters have a low performance compared with other high-rate anaerobic reactors, the UAF, UASB and AFB.
