摘要:
利用石油化工企业剩余污泥研制污泥基填料,通过单因素试验,考察气水比、水力停留时间(HRT)和填料层高度对曝气生物滤池(BAF)出水水质的影响。确定了最佳控制参数:气水比为3:1,水力停留时间为5 h,填料层高度为90 cm。在最佳参数条件下,出水水质良好,化学需氧量(COD)去除率达到93.7%,氨氮(NH3-N)去除率达到39.5%,总氮(TN)去除率达到34.3%。用高倍显微镜对填料表面的生物膜进行观察,发现了钟虫和草履虫等水处理常用菌种。
Abstract:
Residual sludge of petroleum chemical waste was used to make sludge-based filler.The effects of gas water ratio,hydraulic retention time(HRT)and packing layer height on the performance of biological aerated filter(BAF)were analyzed by measuring the chemical oxygen demand(COD),NH3-N mass concentration and total nitrogen(TN)mass concentration.The best control parameters were obtained as follows:gas water ratio of 3:1,HRT of 5 h and packing layer height of 90 cm.Under the conditions,the removal rates of COD,NH3-N and TN mass concentration were 93.7%,39.5% and 34.3%, respectively.Biological membrane on the surface of the filler was observed with high magnification microscope, vorticella and paramecium were found when it was used in water treatment.
