摘　　要：污泥深度脱水对污水处理系统至关重要,因为它可以减少污泥容量和污泥的运输费用,然而污泥调理是实现污泥深度脱水的重要途径。实验使用中性纤维素酶或中性蛋白酶调理造纸活性污泥,采用毛细吸水时间测定仪,抽滤和压滤检测生物酶调理对污泥脱水性能的影响,结果表明生物酶调理对活性污泥的脱水性能具有一定的改善作用。Sludge dewatering is crucial for the wastewater treatment systems due to as its decreasing the sludge volume and the sludge transporting cost. Sludge conditioning is an important way to achieve the purpose of deeply dewatering. Neutral-cellulose or neutral-protease was used to adjust/condition activated paper sludge. After conditioning, dewatering properties of sludge were detected by equipment of CST, suction filtration and filter pressing. The results showed that enzyme used to condition activated sludge have posotive effect on dewatering properties of sludge.
