【摘要】：煉油催化劑廢水因NH_3-N含量高、含鹽量高并且水質(zhì)波動大,導(dǎo)致常規(guī)水處理工藝出水不穩(wěn)定。采用短程硝化SBBR工藝,分別研究NH_3-N、高鹽和高pH沖擊下SBBR和SBR的性能差別。結(jié)果表明,曝氣時間為8 h,進(jìn)水NH_3-N質(zhì)量濃度為150 mg/L時,SBBR耐NH_3-N沖擊極限在300 mg/L左右,比SBR抗NH_3-N沖擊能力提升50%;當(dāng)含鹽量在5~50 g/L之間變化時,SBBR和SBR的耐鹽沖擊極限都在25 g/L左右,含鹽量繼續(xù)升高時,短程硝化反應(yīng)依然存在,但受到抑制;pH值在8.0~11.5之間變化時,SBBR耐pH沖擊極限為10.5,此時SBR耐pH沖擊極限為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，
