- 摘要:
- 超滤膜是目前应用较为广泛的饮用水深度处理工艺之一。针对不具备扩建条件的超滤膜深度处理水厂产能提升需求,以南方地区某超滤膜深度处理水厂改造为例,通过更换抽吸泵,进一步释放超滤膜产能;新建清水箱及优化消毒剂投加,增加调蓄容积,并保持消毒剂均匀性;优化自控系统,建立工艺联动控制方式,提升自动化程度,实现活性炭罐与超滤膜池根据清水池液位自动开停,保持运行平稳,减少人工操作。改造后该水厂制水及供水能力挖潜提高15%,生产运行稳定达标,部分指标优于《生活饮用水卫生标准》(GB 5749—2022)、《饮用净水水质标准》(CJ 94—2005),总投资控制在260万元以内,基本实现少人值守,可为相关水厂挖潜改造提供借鉴。
- Abstract:
- Ultra-filtration membrane (UFM) is currently a widely used advanced treatment process. In response to the demand for capacity increase of UFM waterworks that does not have expansion conditions, taking the transformation of a UFM advanced treatment waterworks in the southern region as a case, the UFM capacity was further released by replacing the suction pump. New clean water tanks were built to increase the storage volume, and the disinfectant addition was optimized to maintain the uniformity of the disinfectant. The automatic control system was optimized to link the processes and to improve automation degree, so that the activated carbon tank and UFM tank could be automatically started and stopped according to the liquid level of the clean water tanks, for maintaining stable operation and reducing manual operation. After the transformation, the waterworks’ water production and water supply capacity have been tapped by 15%, and the production and operation have been stable and up to standard. Some indicators were superior to the Standards for Drinking Water Quality (GB 5749-2022), Water Quality Standards for Fine Drinking Water (CJ 94-2005). The total investment was controlled at 2.6 million yuan, and basically fewer people on duty have been achieved. It could provide technical reference for potential tapping and transformation of related waterworks.
