采用常规水质分析方法、XAD树脂分离方法和微波消解/电感耦合等离子体质谱(ICP-MS)法对纤维素乙醇废水进行水质特性分析。结果表明,纤维素乙醇废水具有极高的 COD 浓度、色度和无机盐含量,缺少N、P等营养元素以及Co、Ni等微量金属元素,基本没有重金属元素。总体上说,纤维素乙醇废水以亲水性有机物(HiA、HiN和HiB)和酸性有机物(HiA和AHS)为主,其DOC百分比分别为72%和64%,疏水性有机物(HoA、HoN 和 HoB)的含量较少,多为长链有机物,其芳构化的程度较低。针对纤维素乙醇废水的水质特性,本文提出采用IC——UASB——MBBR——臭氧氧化——BAF以及沼气脱硫处理组合工艺流程。

Quality characteristics of cellulosic ethanol wastewater were analyzed by conventional means, XAD resin separation and microwave digestion/ICP-MS. The results show that the cellulosic ethanol wastewater has high COD concentration, color and inorganic salt content, and it contains almost no heavy metals and lacks N, P nutrients as well as Co, Ni and other trace metals. Generally speaking, hydrophilic organic matter (HiA,HiN and HiB) and acidic organic matter play a dominant role in the cellulosic ethanol wastewater,comprising 72% and 64% of the total DOC concentration. Most of hydrophobic organic matter (HoA, HoN and HoB) are long-chain organic compounds, whose aromatization degree is low. For the quality characteristics of cellulosic ethanol wastewater, a treatment process combining IC - UASB - MBBR - ozone oxidation - BAF with biogas desulfurization was put forward.
