- Abstract:
- The microbial community in the sediment of clean water tank from a waterworks in northern China was analyzed by Illumina MiSeq high-throughput sequencing. The species and relative abundances of bacteria, archaea and fungi were analyzed at phylum and genus levels. The causes of their growth and their influence on the safety of the user water quality were explored, and the solutions and suggestions were proposed. The bacterial community of the sediment included 30 phyla, 55 classes, 79 orders, 152 families and 410 genera, the archaeal community had 9 phyla and 18 genera, and the fungal community consisted of 4 phyla and 16 genera. The abundance of the microbes in the sediment of the clean water tank was high, and they all belonged to the common microorganisms in water and soil. There were trace bacteria that might cause disease and endangered the security of the water quality. The reasons might be incomplete disinfection and pipeline corrosion. Therefore, it was suggested to appropriately increase the dosage of disinfectant, ensure the residual disinfectant in the pipe network, and strengthen the maintenance, management and water quality detection of the water supply pipe network.
