在一次大型演习部队进驻前期,我部对参演部队生活用水的水质实施连续监测中发现,原水质良好的水源受到了微生物污染,细菌总数及大肠菌群均超标。立即实施调查处理。该水源为某部生产矿泉水的自备深水井,井深474m,井口建有泵房,防护良好。供水流程为水井→潜水泵提水→蓄水池→水塔→管网用户,无消毒设施。经调查,因机械故障,在取样的前1d,曾吊上潜水泵拆卸维修,在未进行任何清洗消毒的情况下投入使用,蓄水池中可见新鲜泥沙样沉积
In the early stage of the stationing of a large-scale force, the Ministry of Water Resources conducted continuous monitoring of the water quality of the domestic troops participating in the exercise. It found that the water source with good water quality was contaminated by microorganisms, and the total number of bacteria and coliform bacteria exceeded their standards. Immediate investigation and handling. The source of water for the production of some of the self-produced deep water wells, well depth 474m, wellhead built pumping station, well protected. Water supply process for the wells → submersible pumps → reservoir → water tower → pipe network users, non-sterile facilities. After investigation, due to mechanical failure, in the first 1d before sampling, had submersible pump demolition maintenance, without any cleaning and disinfection in the case, the reservoir can be seen fresh sediment sediment
