摘　　要：水力空化技术是一种新型的物理工艺化学机理的消毒方法。本文考察了入口压力和多孔板几何参数对消毒效果的影响,水力空化技术对次氯酸钠消毒效果及副产物的形成与去除的影响。结果表明,入口压力越大,消毒效果越好;水力空化技术与次氯酸钠联合使用时,提高了药剂的杀菌效果,既可以减少药剂的用量,也缩短了杀菌时间;而且对次氯酸钠消毒产生的三氯甲烷,水力空化技术有抑制和消除作用。Hydrodynamic cavitation （HC） is a new disinfection method which belongs to physical process and chemical mechanism. In this paper, the effeet of inlet pressure and porous plates geometrical parameters On disinfection is discussed in detail. It was shown that, the greater the inlet pressure, the better the disinfection effect. The use of hydrodynamic cavitation technique in combination with sodium hypochloride could raise the disinfection effeet; the chemical dosage was reduced and dsinfection time was shortened as well, moreover, the hydrodynamic cavitation technique had a inhibition and removal action on chloroform generated from the hypochloride disinfection.
