| 摘 要： | 麦草秸秆化学热磨机械浆(CTMP)废水含有较高的COD及氮、磷含量,采用升流成厌氧反应(UASB)-序批式反应器(SBR)-深度处理三段工艺,在不添加任何营养盐的条件下,对其进行处理研究。结果表明,在UASB厌氧阶段进水体积负荷为6kg/(m3·d),SBR处理进水COD 1 400mg/L,曝气时间为24h,缺氧搅拌25min,深度处理自制药剂A用量为0.15%时,处理效果良好,可使废水出水COD为 71.18mg/L,总氮(TN)为5.43mg/L、总磷(TP)为0.71mg/L,色度为33,达到国家排放标准。

| Abstract: | The wastewater from wheat straw chemithermomechnical pulp (CTMP) pulping process contained high COD, nitrogen and phosphorus. It was treated by upflow anaerobic sludge blanket (UASB), sequencing batch reactor(SBR) and deep treatment process without adding any nutrient. The results showed that when the influent volume load of UASB anaerobic phase was 6kg/(m3·d), aerobic treatment time was 24h and anoxic minxing time was 25min in the SBR treatment, and the addition of reagent A was 0.15% in deep treatment, the COD, total nitrogen(TN) content, total phosphorus(TP) content and color could reach 71.18mg/L, 5.43mg/L and 33. This treated water met the national discharge standard. |
