摘要
以焦化废水为研究对象，采用不同规格的球形轻质陶粒作填料，在厌氧生物滤池中对焦化废水进行了处理，目的在于加强对难降解物质的去除度部分水解功能。实验结果表明，在停留时间9～12h下，能同时兼顾有机物去除和废水的可生化降解性，为后续段时废水的进一步处理创造了有利条件。
Coke plant wastewater was treated bY the composite anaerobic biological filters,which was packed with expanded spherical clay. Under the condition of the influent liquid temperature 20-250℃, HRT 9-12 h, mixture liquid recycle ratio 3 ： 1 ,aeration undertaken using a constant air.liquid ratio of （3-6） ： 1, the results indicated that anaerobic unit acted an important role on removal of both organic simple nitrogen heterocyclic compounds and phenol of the wastewater treated. The system could effectively remove the pollutant and the average removal rate of COD,BODs was 30.2% ,36.7% ,respectively. The quality of effluent met the need of fol- lowing treatment.
