摘要
研究了附着缺氧-生物膜工艺处理聚酯废水的影响因素及效率。结果表明:当进水重铬酸钾化学耗氧量低于1400mg/L,缺氧段有机负荷小于3.36kg/(m3.d),总停留时间为18h时,重铬酸钾化学耗氧量去除率大于90%;工艺中缺氧段有效地提高废水的可生化性,丰富的生物相及生物量增强了系统耐冲击负荷的能力。
The influencing factors and efficiency are studied when the process of attached anoxic -oxic biological film process is applied to the treatment of polyester wastewater. When the CODCr of influent is lower than 1400mg/ L, organic load of anoxic zone is less than 3.36kg/（m^3·d） and total HRT is 18h, festively and plenty of microorganisms enhance the durability against shock loading.
