摘要:

采用SH-A强化脱氮除碳工艺对煤系针状焦生产废水进行了实验研究,详细讨论了各个处理环节的运行情况和处理效果。通过该工艺处理后的废水各项指标均达到国家污水综合排放一级标准(GB 8978—1996),NH3-N去除率达96.3%~100%,COD去除率达92.4%~94.2%。

Abstract:

Experiment and study are carried out with SH-A strengthened denitrogenation and carbon removal process for the wastewater from the coal based needle coke production. The operation conditions and treatment result at various sections are discussed in detail. After treatment with the process, the various indexes of the wastewater can meet the national grade I comprehensive effluent discharge standard (GB 8978—1996), the removal rate of NH3-N is up to the range from 96.3% to 100% and removal rate of COD up to the range from 92.4% to 94.2%.
