摘要
采用颗粒污泥接种UASB厌氧反应器处理废纸造纸废水,对其可生化性及能降解程度进行研究。通过持续近2个月的运行实验可知:在进水CODCr质量浓度为2000～3000mg/L的情况下,COD容积负荷最高可达到20kg/(m3·d)左右,水力停留时间可缩短至4h,有机污染物的去除率稳定保持在80%～90%的范围内,并且运行稳定。
Using the granule sludge inoculation UASB reactor to treat regenerating papermaking wastewater and its biodegradability and degradability were studied. Near two-month running experiment showed that when the CODc, of the influent is 2 000 - 3 000 mg/L, the maximal COD volume load is about 20 kg/（m3. d） and the HRT is decreased to 4 h. and removal rate of the organic material is stably kept at the range from 80% to 90%.
