摘　　要：文章在实验室条件下研究了采用普通活性污泥工艺处理宣纸废水时,温度、pH值、溶解氧、污泥回流比和曝气池停留时间对CODCr去除率的影响。实验结果表明,温度、pH值、污泥回流比、曝气池停留时间对CODCr去除率的影响是显著的,而溶解氧对CODCr去除率的影响并不显著。在最优组合条件下,CODCr去除率可达到65%。The experiments were conducted by controlling the temperature, pH value, dissolved oxygen（DO）, sludge reflux ratio and retention period in the aeration tank when using normal activated sludge technology to treat Xuan paper wastewater in order to study the impact Of them on CODcr re- moval ratio. The results show that the impact of temperature, pH value, sludge reflux ratio and re- tention period in the aeration tank on CODcr removal ratio is obvious, however the impact of DO is not obvious. The COI）cr removal ratio can reach 65 G if all factors are controlled under best conditions.
