摘要:: 次氯酸钠消毒工艺在饮用水厂已经得到了广泛应用，对某水厂3台有效氯产量为20 kg/h的次氯酸钠发生器在有效氯浓度、氯酸盐浓度、盐耗、电耗等方面进行了对比研究。结果表明，3台发生器（进口F1^#和F2^#，国产C1^#）产出有效氯的平均浓度分别为0.81%、0.79%和0.85%，基本达到0.8%的设计有效氯浓度要求；产液中氯酸盐与有效氯的比值分别为4.8%、4.9%、1.2%，也均低于《人类消耗水处理用化学品——次氯酸钠》（BS EN 901—2013）中5.4%的要求，C1^#副产物氯酸盐的含量仅为F1^#和F2^#的24%左右。C1^#发生器在夏季、正常、冬季3种模式下的电耗均低于F1^#和F2^#，其中，在冬季模式下C1#采用电解槽换热方式代替压缩机加热，进一步降低了发生器的电耗。F1^#、F2^#、C1^#的平均运行成本分别为6.8、6.7、5.6 元/kg，C1^#由于低电耗的优势，运行成本低于F1^#和F2^#。同时，相比进口次氯酸钠发生器1年的保修年限，国产发生器的保修年限为5年，具有较强的竞争力。

Abstract:: The sodium hypochlorite disinfection process has been extensively applied in drinking water treatment plants. Three large-scale sodium hypochlorite generators with active chlorine production of 20 kg/h were compared in terms of active chlorine concentration, chlorate, salt consumption, and power consumption. The results showed that the average concentrations of active chlorine produced by three generators ( F1^#, F2^# and C1^#) were 0.81%, 0.79%, and 0.85%, respectively, which met the design concentration of about 0.8%. The ratios of chlorate to active chlorine in the effluent of the three generators ( F1^#, F2^# and C1^# ) were 4.8%, 4.9% and 1.2%, respectively, meeting the requirements of less than 5.4% specified in Chemicals Used for Treatment of Water Intended for Human Consumption—Sodium Hypochlorite (BS EN 901-2013). The chlorate by-product concentration of C1^# was only around 24% of that of F1^# and F2^#. The power consumption of C1^# generator was lower than that of F1^# and F2^#under summer mode, normal mode, and winter mode. Among them, in winter mode, C1^# adopted electrolytic cell heat transfer instead of compressor heating, further reducing the power consumption of the generator. The average operating cost of three generators ( F1^#, F2^# and C1^# ) were 6.8 yuan/kg, 6.7 yuan/kg and 5.6 yuan/kg, and C1^# was lower than F1^# and F2^# resulted from its lowest power consumption. In addition, compared to the 1-year warranty period of the imported sodium hypochlorite generators, the warranty period provided by the domestic generator was 5 years, which was highly competitive.
