水力停留时间对接触氧化处理高氨废水的影响

Impacts of hydraulic retention time on high ammonia wastewater treatment with contact oxidation

采用二级接触氧化工艺进行了高氨废水短程硝化模拟试验研究,研究了水力停留时间对NH3-N的去除率、碱度、短程硝化的影响,试验结果表明:采用二级接触氧化工艺,NH3-N为600 mg/L条件下的设计水力停留时间为12 h,及氨氮的容积负荷为1.10 kg/(m3.d)左右。

This paper makes nitrification of high ammonia wastewater simulation test study with secondary contact oxidation process,studies impacts of the hydraulic retention time on the removal rate of NH3-N,alkalinity, and nitrification.The results shows that： through adopting secondary oxidation process,under the condition of 600 mg/L of NH3-N,the design hydraulic retention time was 12 h,and ammonia nitrogen volume load is about 1.10 kg/（m^3·d）.
