摘要
采用ABR(厌氧折流板反应器)对苏州市甪直镇以印染废水为主的工业废水进行预处理,以改善其可生化性,为生物处理创造有利条件。研究结果表明,经过ABR处理后的废水,部分大分子难降解的有机物分解为小分子有机物,废水色度由160降至90,ρ(BOD5)∶ρ(CODCr)从0.22提升至0.31。
Dye-based industrial wastewater was pretreated by anaerobic baffled reactor（ABR） in Luzhi town,Suzhou,to improve its biodegradability and create favorable conditions for the biological treatment.The results showed that in the treated wastewater by ABR,some macromolecular refractory organic matter was decomposed into small molecular organic compounds,chroma reduced from 160 to 90,and B/C value increased from 0.22 to 0.31.
