摘要
在实验室模型试验中得出了最经济沉后水浊度的存在性，为了进一步验证最经济沉后水浊度在天然原水和连续运行系统中的可行性．在天津J水厂进行了中试．研究表明，最经济沉后水浊度在中试系统的运行中仍然存在．在2003年9月到11月3个月的连续运行中发现，存在浊度3．0NTU的最经济沉后水浊度值使系统综合可变费用最低，与天津J水厂的现行控制沉后水浊度2．0NTU相比较，可以实现节约综合可变费用8％～11．6％．
In jar test, it is demonstrated that there is the most economic turbidity of settled water. In order to verify its possibility in nature water and continuous operation system, the pilot-scale experiments is operated in Tianjin J water plant. The results show that the most economic turbidity of settled water also exists in the system. Under the continuous operation from September to November in 2003, it is found the most economic settled turbidity is 3.0 NTU, which can make the total variable costs of system be the lowest, comparing to 2.0 NTU which controlled by J plant in Tianjin, it can reduce its total variable costs of system by 8 % - 11.6 %.
