目的为评价海水淡化厂水质状况。方法按GB5750 -1985《生活饮用水检验方法》采用反渗透法进行淡化后海水成品水微生物、氯化物及 pH检验。结果淡化后海水氯化物浓度为426mg/L ,细菌学指标 (细菌总数 )检测9次其中3次不合格 (分别为350、300、4016个/L) ,pH值基本合格 ,其中一次偏酸5.74 ,一次偏碱8.94。结论采用该海水淡化系统 ,其氯化物残留量偏高 ,接近农村生活饮用水三级标准最高限量 ,成品水微生物指标和 pH值不稳定
Purpose To evaluate the water quality of desalination plants. Methods according to GB5750 -1985 “drinking water test method” using reverse osmosis desalination of marine products after the water microbial, chloride and pH test. Results After the desalination, the concentration of seawater chloride was 426mg / L, the bacteriological indexes (total number of bacteria) were detected three times and failed three times (350,300 and 4016 cells / L, respectively). The pH was basically qualified. , A slight alkaline 8.94. Conclusion The seawater desalination system has a high chloride residue, which is close to the highest level of the third-grade standard for drinking water in rural areas. The indicators of microbial water quality and the pH value of the finished product are not stable
