Journal: WATER & WASTEWATER ENGINEERING

Keyword:  化工废水厌氧水解生物接触氧化特效菌;
Abstract: 采用厌氧水解-生物接触氧化法处理苯胺类化工废水,并在生物接触氧化池中引入苯胺特效降解菌--STR-NiTRO.结果表明:该工艺厌氧段能增强系统耐冲击负荷能力,并有效地提高废水的可生化性;STR-NiTRO菌能有效地去除废水中的苯胺;当进水COD平均617.5 mg/L,NH3-N45.0 mg/L,苯胺25.8 mg/L的条件下,出水COD平均达87.2 mg/L,NH3-N 9.9 mg/L,苯胺0.56mg/L,去除率分别为85.9%,78%,97.8%,出水达到GB8978-96一级排放标准.
