水力空化降解苯酚、二甲苯试验研究

Experimental Study on Degradation of Phenol and Xylene

采用多洞孔板作为水力空化的发生装置,研究了水力空化对苯酚、二甲苯的降解效果。通过试验,得出了苯酚浓度为30-40mg/L时,其降解率最高可达39.1%,二甲苯浓度为3.0-3.6mg/L时,其降解率最高可达55.35%;酸性条件较中性、碱性条件更有利于苯酚、二甲苯的降解;随着水力循环时间的延长,苯酚、二甲苯的降解量呈增大趋势。

Phenol and xylene degradation by hydrodynamic cavitation were studied using Multi-orifice plates as the generating device of hydrodynamic cavitation.Results obtained from experiments show that the phenol degradation rate is 39.1% when its concentration is 30 - 40mg / L and the xylene degradation rate increases up to 55.35% when its concentration is 3.0- 3.6mg /L.Acidic condition is more conducive to their degradation than neutral and alkaline conditions.With long hydraulic cycle time,the amount of phenol and xylene degradation tends to increase.
