摘　　要：通过电解参数对发生器运行效果影响试验,采用单因素方差分析方法,研究了盐水pH值、盐水浓度、电流密度、盐水流量等电解参数对发生器运行效果指标有效氯浓度、交流电耗、盐耗和运行成本的影响。结果表明:盐水pH值对发生器运行效果有显著性影响,盐水为中性时发生器运行效果最好;盐水浓度、电流密度与盐水流量对发生器运行成本均无显著影响,但对有效氯浓度均有显著性影响;盐水浓度、电流密度增加,有效氯浓度提高;盐水流量增加,有效氯浓度降低;设备Tjb-7.5的最佳工况为:盐水流量6L/h,电流密度为18A/dm2,盐水浓度为30g/L,此时设备有效氯浓度7.01g/L,运行成本最低9.52元/kg。The experiment of electrolysis parameters （pH of salt water ,salt water concentration ,current density and salt water flow ） on the operation performance indexes （concentration of available chlorine ,alternating current consumption ,salt consumption ,and operating cost） of the non-diaphragm sodium hypochlorite generator is conducted and the results show that ：pH of salt water have a significant influence on the running effect of the generator .When the pH of salt water is neutral ,the running effect of the generator is the best .And salt water concentration ,current density and salt water flow have no significant influence on the generator operating cost but a significant influence on the concentration of available chlorine .When salt water concentration or current density increases , the concentration of available chlorine increases .When salt water flow increases ,the concentration of available chlorine decreases . To Generator Tjb-7 .5 ,when pH of salt water is 7 .5 ,salt water concentration is 30 g/L ,current density is 18 A /dm2 and salt water flow is 6 L /h ,the operating cost is the lowest ,9 .52 yuan/kg .
