武汉市桶装饮用水生产企业洁净灌装间的净化效果

目的了解武汉市桶装饮用水生产企业灌装间空气洁净装置的净化效果。方法于2002年按照GB50073—2001《洁净厂房设计规范》、GB／T16294—1996（（医药工业洁净室（区）悬浮粒子的测试方法》、GB／T16249一1996（医药工业洁净室（区）沉降菌的测试方法》，对32家桶装水生产企业的灌装车间空气洁净度进行检测，依据GB17324—1998（瓶装饮用纯净水卫生标准》、GB8537—1995（（饮用天然矿泉水卫生标准》、CJ94-1999（饮用净水水质标准》进行检测。结果32家企业灌装间尘埃数的合格率为78．1％，细菌总数合格率为81．3％。按洁净度分级结果显示，符合10000级标准的灌装车间为25户，占78．1％；符合1000级的有8户，占25％；而生产线局部符合100级的有2户，占6.3％。灌装间温度、照度、噪声的合格率均为84．4％；风速的合格率最高，为87．5％；相对湿度合格率为46．9％；室内外压差合格率为34．4％，实施卫生规范化管理后，桶装饮用水的微生物指标合格率从2001年的61．1％上升为2002年的84．1％。结论桶装饮用水灌装问采用洁净装置可以提高桶装饮用水的微生物学的卫生质量。

Survey on Purifying Effects of Clean Bottling Workshop in Jugged or Bottled Drinking Water Manufacturing Enterprise

Objective To explore the purifying effects of clean bottling workshop in jugged or bottled drinking water manufacturing enterprise in Wuhan. Methods 32 manufacturing enterprises were sampled to test the purifying levels of bottling workshops according to GB50073-2001 The Criterion for Purifying Workshop Design, GB/T16294-1996 Detecting Method for Suspended Particle in Clean Shop or Area of Medical Industry and GB/T16249-1996 Testing Method for Sedimentation Bacteria in Clean Room or Area of Medical Industry. The microorganism determination was based on GB17324-1998 The Hygiene Standard for Bottled Drinking Pure water and GB8537-1995 The Hygiene Standard for Drinking Natural Mineral water and CJ94-1999 The Hygiene Standard for Bottled Drinking Water. Results The qualified rate was 78.1% for the count of dust in air and 81.3% for the count of bacteria in air of bottling workshops of 32 manufacturing enterprises.Among 32 manufacturing enterprises, 25(78.2%) and 8(25%) enterprises accorded with the requirement of 10 000 and 1 000 purifying level of air in whole bottling workshop respectively,only 2 accorded with the requirement of 100 purifying level of air at product line in bottling workshop. The qualified rate was 84.4% for temperature,light,noise,87.5% for flow rate, 46.9% for relative humidity, 34.4% for air pressure difference between indoor and outdoor.After the performance of sanitary management, the qualified rate of microorganism in barrelled water increased from 61.1% in 2001 to 84.1% in 2002. Conclusion The application air cleaning facility in bottling workshop of jugged or bottled drinking water manufacturing enterprise can improve the sanitary quality of microorganism in barrelled water.
