摘 要

本实验是通过向原始石化污泥中添加不同的调理剂，在相同的条件下进行反应，增大污染物颗粒的大小以改善其脱水性能，通过测定其CST、多糖、比阻、蛋白质等以探究不同调理剂对石化污泥脱水性能的影响。实验结果表明在单因素的测定中Fenton20-5可以明显提高总糖和蛋白质的含量，分别提高了374.70%和460.89%，同时提高了脱水性能把CST降低了65.74%。Fenton15-5在其他单因素的测定中效果不明显但在比阻的测定项中效果最好，把比阻降低了42.31%，相对于Fenton25-5提升了2.61%。总体上而言Fenton25-5在改善污泥的脱水性能的综合表现上最明显，把VSS降低了4.85%，蛋白质含量提高了334.84%，多糖含量提高了355.18%，比阻降低了39.7%，CST降低了63.88%，有效提高了污泥的脱水性能。并且在不同因素的测定中，芬顿试剂的性能均优于高分子聚合物。

Effects of different agents on petrochemical sludge dewatering performance

ABSTRACT

The experiment is done by adding the conditioning agent to the petrochemical raw sludge, under the same reaction conditions, increase the size of contaminant particles to improve the dewatering performance, measured by the CST, polysaccharides, specific resistance, and other proteins in explore the effects of different agents on petrochemical sludge dewatering performance. Experimental results show that the single factor in the determination of Fenton20-5 can significantly improve the content of total sugar and protein were increased by 374.70% and 460.89%, while improving the performance of the dewatering CST reduced 65.74%. Fenton15-5 other single factor in the determination of the effect is not obvious, but in terms of specific resistance was measured in the best, the specific resistance decreased 42.31%, compared to 2.61% Fenton25-5 improved. General terms Fenton25-5 in improving sludge dewatering performance and overall performance of the most obvious, the VSS decreased 4.85%, protein content increased by 334.84%, 355.18% polysaccharide content increased, the specific resistance decreased 39.7%, CST decreased 63.88%, effectively improve the performance of sludge dewatering. And in the determination of different factors, the performance of Fenton's reagent were superior polymers.
