摘要
目的通过对吴江市近5年的饮用纯净水监测资料进行系统的整理、分析、评价,以发现不安全隐患及管理中存在的问题,为加强饮用纯净水监测与管理提供依据。方法根据数据类型和分布特征采用相应的统计描述与推断方法,运用差距分析法进行安全性评价,并结合定性访谈结果进一步分析产生差距的原因。结果吴江市桶装饮用纯净水厂的主要生产工艺为“预处理—反渗透—灭菌”;纯净水超标项目主要是电导率和菌落总数;不同管理等级企业纯净水中浑浊度、高锰酸钾消耗量、电导率、菌落总数间差异有统计学意义,A组企业的纯净水水质较B、C级企业的纯净水好。结论A级企业的纯净水较B、C级的更安全;菌落总数、电导率是目前B、C级企业纯净水的不合格因素。建议:改变现行监测策略,确定重点监测对象和检测项目,加大对B、C级生产企业的监测力度;加强相关人员培训;尽可能改造B、C级生产企业的工艺设备;对纯净水是否影响人体健康应作进一步深入研究。
Objective To detect hidden problems of insecurity and management for drinking water,and to strengthen monitoring and managment,Methods A descriptive statistical methods was employed ,A qualitative method,such as key informant interview was also used to evaluate the causes of the disparities,Results The main production processes of barreled purified drinking water comparry in Wujinang were ＂ preprocess -Reverse Osmosis -sterilization＂,The over-standard indicator for pure water was the total of bacterium and conductance,There were significant diffcrences in tubidity,potassium pemanganste comsumption,coochxtance and the toatl of bacterium of pure water of different managenent -level company,The quality of pure water in A-class erderpris was better than the B,C-class enterprises ,Conclusion The pure water in A-class enterprises is more safety than the B-and C-class enterprises ,The nonconformity indicator in B-and C-class enterprises is conductance and the total of bacterium ,Sugestions：Changing the present inspection strategy;determinging key inspection objects and indicatiors;strengthening the supervision on B-and C-class erteprises;strengtbening the training for the workers and managers;reforming the technological equipment of B-and C-class enterprise as far as possible;making the furthe research in -depth for whether pure water influxces the health.
