佛山市供水水质生物稳定性调查结果显示:1.佛山市管网水整体上属生物稳定性的饮用水。2.浊度对 AOC 的影响较大,尤其是夏季汛期时,对高浊水要处理好浊度对净水过程的影响,保证出厂水的浊度在一个较低的水平。3.管网中的剩余消毒剂对保证水质的微生物安全很重要,有较高的 AOC 水平,如果有足够的消毒剂,微生物指标也可以达标。在安全和经济的前提下,要保障管网消毒剂的水平,尤其是管网末梢水的消毒剂水平。4.管网的使用期对 AOC 影响比较明显。老旧管网中 AOC 的水平较高,微生物生长的潜在风险较大。为保障水质微生物安全,要重视对老旧管网的更换。
Foshan City, water quality and biological stability of the survey results show: 1. Foshan pipe network water as a whole is biologically stable drinking water. 2. Turbidity has a greater impact on AOC, especially in the summer flood season, turbidity should be dealt with on the high turbidity water purification process to ensure factory water turbidity at a lower level. 3. Remaining disinfectants in the pipe network are important to ensure the safety of water quality microorganisms and have a high AOC level. Microbial indicators can also be achieved if sufficient disinfectants are available. Under the premise of safety and economy, it is necessary to ensure the level of disinfectant in pipe network, especially the level of disinfectant in the water of pipe network. 4. The use of pipe network AOC more obvious. AOC in older networks is at a higher level and the potential risks of microbial growth are greater. To ensure the safety of water quality microorganisms, attention should be paid to the replacement of old pipe network.
