【摘要】 目前降低给水管网中生物可降解性有机碳(BDOC)已成为水厂迫切需要解决的主要问题,为此以东北某水厂为例,研究了出厂水的BDOC阈值问题,并对出厂水BDOC浓度对给水管网中游离性细菌、吸附性细菌的再生长的影响进行了探讨。结果表明,出厂水BDOC浓度阈值为0.2mg/L;当BDOC浓度发生变化时,游离性细菌变化量没有吸附性细菌变化量大。更多还原

【Abstract】 The reduction of biodegradable dissolved organic carbon (BDOC) in water distribution network is a problem need to resolve urgently for water plant.Based on this,study was made on the BDOC threshold of the finished water in a water plant located in northeast China,and the correlation of BDOC concentration in finished water with re-growth of free and adsorptive bacteria were also discussed.The result shows that the threshold of BDOC level is 0.2 mg/L.When BDOC concentration changes,the quantity variance in adsorptive bacteria is greater than free bacteria.更多还原
