工业废水中的生物脱氮工艺及其应用效果比较

氨氮已成为＂十二五＂规划中污染物约束性指标.基于现有的微生物脱氮工艺的应用案例,对比分析了不同工艺的微生物脱氮方法的适用条件（进出水浓度、HRT、膜材料、载体等）、处理效果和运行成本.同时,系统分析了不同工艺的适用性和优缺点.不同的处理工艺适用处理的氨氮浓度虽有差异,但其出水中氨氮的浓度大部分可达到直接排放的标准.从应用案例的比较可以看出,针对同一种废水不同工艺或同一工艺处理不同性质的废水,处理成本可能有较大差异,需要对比优选.研究结果可以为生物脱氮的废水处理工艺和参数选择提供参考.

Comparative Analysis of Biological Ammonia Nitrogen Removal Processes in Industrial Wastewater

Ammonia nitrogen has been one of the water pollution control binding targets in 12th Five Year Plan. This paper based on biological applications, compares and analyzes the applicable conditions, treatment effects and costs on different biological processes. It also analyzes applicability, advantages and disadvantages among different processes. Though the processes have different influent ammonia requirement, their effluent ammonia mostly can be discharged directly. By comparing and analyzing, the conclusion is that the costs are quite different in different processes or industrial wastewater. It can be a part of basis in choosing biological ammonia nitrogen wastewater removal process and parameters.
