1,4-丁二醇废水厌氧可生化性研究

摘要

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.
