【摘要】：炼油催化剂废水因NH_3-N含量高、含盐量高并且水质波动大,导致常规水处理工艺出水不稳定。采用短程硝化SBBR工艺,分别研究NH_3-N、高盐和高pH冲击下SBBR和SBR的性能差别。结果表明,曝气时间为8 h,进水NH_3-N质量浓度为150 mg/L时,SBBR耐NH_3-N冲击极限在300 mg/L左右,比SBR抗NH_3-N冲击能力提升50%;当含盐量在5~50 g/L之间变化时,SBBR和SBR的耐盐冲击极限都在25 g/L左右,含盐量继续升高时,短程硝化反应依然存在,但受到抑制;pH值在8.0~11.5之间变化时,SBBR耐pH冲击极限为10.5,此时SBR耐pH冲击极限为10.0。
[Abstract]:Because of the high content of NH_3-N, high salt content and large fluctuation of water quality, the effluent of conventional water treatment process is unstable. The performance difference of SBBR and SBR under high salt and high pH impact of NH_3-N, was studied by short-cut nitrification SBBR process. The results showed that when the aeration time was 8 h and the influent NH _ 3 鈮，
