废纸造纸废水有机污染物的降解研究

采用同时厌氧-好氧反应器处理广东某造纸厂废纸造纸废水,平均出水浓度COD为89.70mg/L,VFA为0.89mg/L,达到了GB3544-2001《造纸工业水污染物排放标准》。同时选用GC-MS联用仪对废纸造纸废水中的有机物进行测定,共测得有机污染物89种,其中8种有机污染物被列入美国EPA环境优先控制污染物,在进水的50种有机物中,32种有机物被完全去除。通过分析有机污染物在各工艺段的分布情况,揭示其在厌氧-好氧生物处理过程中的降解与转化规律。

Degradation of Organic Pollutions in Wastewater from Regenerated Papermaking

A set of simultaneous oxic and anaerobic bioreactor was used to treat regenerated papermaking wastewater generated from some paper mill in Guangdong,China.Results demonstrated that average effluent concentration of COD and VFA was 89.70 mg/L and 0.89 mg/L respectively,both of them could be controlled below the Chinese discharge standard of GB 3544-2001.Moreover,GC-MS analysis was used to measure organic pollutants contained in regenerated papermaking wastewater.90 kinds of organic matters were detected and discovered,and 8 of them belonged to the list of environmental priority pollutants which was considered by EPA in USA.32 of 90 kinds of organic pollutants in the inffluent were completely removed.Distribution of organic pollutants in each process was analyzed to discover the degradation and transformation law in the process of simultaneous oxic and anaerobic treatment.
