广州西村和石门水厂取水口迁址的论证分析

采用网河区非稳态水量，水质数学模型，对广州西衬和石门两水厂的拟搬迁方案进行了详细的论证分析。分析结果表明：拟迁址处的水质较现水源地的水质明显改善；在控制好未来污染源的条件下，拟迁址处的水质基本可满足水源的要求。

Analysis of both Water Quantity and Water Quality for New Water Intake of Xichun and Shimen Water Plant in Guangzhou

An unsteady water quality and quantity model for river networks has been used in determining the new water intake of Xichun and Shimen water plant,Guangzhou,China.The data of hydrology and water quality observed simultaneously,and the water quantity and quality at Yanang station are evaluated.Based on the water quantity assurance rate (97%),the water quantity at the new water intake is computed.The computed result shows that the water quantity will be as high as 300?m 3/s at the new place,so the engineering effects on water quantity at the new intake will be small.The future pollution sources and the boundary water quality conditions are considered.The computation results show that the water quality at the new intake is better than that at the previous one.With suitable control of the pollution sources around the new area in the future,the water quality and water quantity at the new intake can meet the requirements.
