摘要:N,N-二甲基甲酰胺(DMF)及其分解产物二甲胺(DMA)具有较强的生物硝化毒性。经过驯化的城市污水厂活性污泥仍受到DMF与DMA的硝化抑制,50%硝化抑制时对应的DMF和DMA分别为47.1 mg/g和10.1 mg/g。而来自制药废水处理系统的活性污泥,经过驯化后能够完成硝化过程,但其允许的DMF及DMA最大质量浓度分别为200、80 mg/L。研究结果对指导含DMF废水处理工程的设计与调试有一定参考意义。
N,N-dimethylformamide(DMF)and its decomposed product dimethylamine(DMA)both have strong biological nitration toxicity.The activated sludge after acclimatization from urban sewage treatment plant is still subject to DMF and DMA nitrification inhibition.The concentrations of DMF and DMA corresponding to 50%nitrification inhibition are 47.1 mg/g and 10.1 mg/g,respectively.The activated sludge from pharmaceutical wastewater treatment system,after acclimatization,can accomplish the nitrification process,but the maximum allowable mass concentrations of DMF or DMA are 200 mg/L and 80 mg/L,respectively.This research result has certain reference significance for guiding the design and debugging of DMF-containing wastewater treatment project.
