摘要
介绍了焦化废水脱氮处理方法,包括物理法、化学法、物理化学法以及生物法,比较了各种处理方法的优缺点。认为生物脱氮技术处理效果较好,工艺稳定、处理成本低,是目前工程设计中应优先考虑的脱氮工艺,其中A/O、A2/O已成熟,而其它工艺有待进一步研究发展。同时认为研制出无二次污染、操作简便、性能稳定、运行成本低的处理技术是今后的发展方向。
Common processes for nitrogen-removal from coking wastewater included： physical process, chemical process, physical-chemical process and biological process were presented, and the advantages and disadvantages of these methods were compared. It was considered that, biological denitrogenation process featured by good treatment effect, stable technology and low cost, which should be the first choice for the engineering design. Technology of A/O, A2/O were mature, while, the other technologies still need for further study. Designing a treatment technology with characteristics of no secondary pollutant, easy to operate, stable performance and low operating costs was considered to be the development direction in the future.
