1,4-丁二醇废水厌氧可生化性研究

Study on the anaerobic biodegradability of 1,4-butanediol wastewater

以陕西某化工厂的1,4-丁二醇生产废水为研究对象,采用厌氧颗粒污泥接种UASB反应器,对其厌氧可生化性进行研究。结果表明,在进水CODcr为4 000 mg/L,水力停留时间24 h,容积负荷为4 kg/(m3.d)时,CODcr去除率稳定在70%左右,系统运行良好。

With the 1,4-butanediol wastewater as treatment object from a chemical plant in Shaanxi,using the granular sludge inoculation UASB reactor anaerobic biodegradability of the wastewater was investigated.Results indicated that when the influent CODcr was 4 000 mg/L,the HRT was 24 h,VLR was 4 kg/（m3·d）,CODcr removal rate kept around 70%.The reactor is operated stable.
