摘要
考察了A/O/O以及O/A/O两种工艺对PAHs削减行为的影响,分析发现A/O/O工艺对水相中总PAHs的去除率为95.85%,高于O/A/O工艺的88.50%;两种工艺中污泥均表现出对4环及以上PAHs的富集;A/O/O工艺对于高环PAHs(4环以上)的生物降解表现出更佳的效果;A/O/O工艺对于总PAHs削减能力为73.44%,高于O/A/O工艺的64.64%,说明A/O/O工艺在PAHs的削减方面要强于O/A/O工艺。
The effects of A/O/O and O/A/O treatment processes on the reduction behavior of PAHs were examined.The results showed that the removal efficiency of the total PAHs in the wastewater in the A/O/O process was 95.85%,which was higher than 88.50% of the O/A/O process. The sludge in both two processes showed concentration enrichment of the PAHs with four rings and above. The A/O/O process showed better results for the biodegradation of refractory high-ring PAHs(more than 4 rings). The PAHs reduction capability of the A/O/O process was 73.44% higher than 64.64% of O/A/O process,which indicated that the A/O/O process was greater than the O/A/O process in terms of PAHs reduction.
