摘要
文章针对合肥燃气集团有限公司的煤气废水水质特点,深入研究A/O-气浮法处理煤气废水的方法,并探讨影响A/O工艺生物脱氮效率的主要影响因素。采用A/O-气浮工艺处理煤气废水的生产实践表明:该工艺能同时去除煤气废水中的有机物和氨氮,主要出水指标COD、氰化物、硫化物、氨氮等达到国家二级排放标准。
In view of the wastewater quality characteristics of Hefei Gas Group Co., Ltd, the A/O-air floatation technology is applied to the treatment of the coal gas wastewater. The treatment method and process are described,and all sorts of factors influencing the efficiency of biological nitrogen removal by A/O technology are investigated.The practical treatment results show that with the A/O-air floatation technology,both BOD and ammonia can be removed from the coal gas wastewater simultaneously,and that the main discharge indices including COD,CN^-,S^(2-),NH__(3)-N can meet Grade Ⅱ requirements according to the national wastewater discharge standard.
