中文摘要:

针对缺水城市大型缓流景观水体水环境容量小、水质易恶化问题，提出了利用水环境容量总量动态控制模型进行水质管理的方法。以天津渤龙湖景观水体为研究对象进行实例研究。水环境容量计算结果表明:渤龙湖自然水环境容量无法容纳污染物输入总量的要求，而水体循环净化系统按照设计负荷运行时，会产生较大的剩余水环境容量。利用模型对渤龙湖水环境容量总量动态控制结果表明，在水体达到IV类水质标准的同时，优化后水体循环净化设施水量负荷可降低46.1%，且水环境容量得以充分利用。

英文摘要:

In the light of problem of small water environmental capacity and bad water quality of urban landscape water body in water-deficient city, the paper proposed a method that use dynamic control model of water environmental capacity and total content to conduct water quality management. Taking Bolong urban landscape lake in Tianjin as a case study,water environmental capacity calculation results of Bolong urban landscape lake showed that natural water environmental capacity cant not satisfy the requirement the total pollutant input, but if water purification system operates according to design patterns, which can produce more remaining water environmental capacity. Using the model to conduct dynamical control for total water environmental capacity in Bolong urban landscape lake and when the water quality standard reach class IV, the water load of water purification system can be reduced by 46.1 percent. The water environmental capacity can be fully used.
