深圳河湾水系水质改善引调水工程

Water diversion project for the improvement of water quality in Shenzhen River-Bay system

深圳河湾污染现状是当城市污水处理率达到95%时,河道依然存在着黑臭现象。利用统计数据建立了3套动态数学模型,进行不同污水处理率下和不同引调水水源的环境需水量计算,确定了合理的污水处理率目标。对深圳河湾水系的珠江口引水和大鹏湾引水方案进行研究:从生态环境角度,首选方案是珠江口引海水加滨海水库水;从工程经济角度,首选方案是大鹏湾引水。

The pollution status in Shenzhen River （Bay） is such that the river is still in black-odor situation when the urban sewage treatment rate reaches 95 %. Based on statistical data, three different dynamic mathematical models were established and used to determine the environmental water demand under different sewage treatment rates and water diversion sources. A reasonable sewage treatment rate goal is provided. The water diversion projects from Zhujiang Estuary and Dapeng Bay to Shenzhen River-Bay system were studied. Results show that the projects of water diversion from Zhujiang Estuary and coastal reservoirs are better for the protection of the ecological environment and the water diversion from Dapeng Bay is better for economical purposes.
