摘　　要：结合自组装的网格型电极,试验研究次氯酸钠发生器在不同盐水温度、不同运行模式、有无冷却措施等情况下的运行效果。试验结果表明：降低电解槽内盐水温度可有效提高次氯酸钠发生器的电解效率。增设循环冷却水或间歇式运行可提高有效氯产量38%～42%、电流效率37%～65%,降低运行成本5.217～10.185元/kg。增设循环冷却水情况下有效氯产量最高可达263g,相应的理论运行成本为8.876元/kg;电解270～310min时,有效氯产量为235～250g,运行成本最低,为7.989～8.066元/kg。在实际应用中,应根据产氯量、运行成本等因素综合考虑电解时间。A new grid-type electrode was assembled for rural water supply projects.Effects of salt water temperature,running modes,cooling measures on efficiency of sodium hypochlorite generator were investigated in this paper.Results indicated that cooling measures could improve the electrolysis efficiency of sodium hypochlorite generator significantly.Circulating cooling water or intermittent operation could increase the yield of available chlorine from 38% to 42%,heighten current efficiency from 37% to 65%and also reduce operating cost from 5.217RMB/kg to 10.185RMB/kg.Sodium hypochlorite generator with circulating cooling water could produce maximum 263 g available chlorine and the operating cost was 8.876RMB/kg in theory.The optimum operation condition could reach lowest operating cost of 7.989～8.066RMB/kg with electrolysis time 270～310min.In actual application,electrolysis time should be determined by available chlorine and operating cost.
