基于水力空化技术的降解特性研究

在多孔板水力空化反应器实验装置的基础上,分析研究了污水初始浓度、循环周期及进水压力等因子对罗丹明B 溶液、生活污水中污染物降解效果的影响. 结果表明进口压力越大,空化程度越强,自由基数量充足则降解效果越好,最佳降解初始浓度在10 mg/L 附近,亚甲基蓝作为催化剂能促进罗丹明B 的降解. 对生活污水中总磷的降解程度优于氨氮的效果近一倍.

STUDY OF DEGRADATION CHARACTERISTICS BASED ON HYDRODYNAMIC CAVITATION

The degradation of the Rhodamine B and the sewage is investigated based on the hydrodynamic cavitation in this paper, including the factors affecting the degradation, such as the cavatation number, the sewage initial concentration, and the cyclic and inlet pressures. It is shown that the degradation of the pollutant water increases with the increase of the inlet pressure, the best degradation of the Rhodamine B occurs in the range of 4 mg/L~10 mg/L, and the TP (total phosphorus) degradation is better than NH4+ by zoo percent.
