南湾水资源回收（SBWR）是一个区域项目，为圣何塞和圣克拉拉以及加利福尼亚州北部硅谷地区其他几个社区的300多个灌溉和工业用户提供不可饮用的再生水。在过去两年中，电力公司已提议在SBWR服务区内修建近12座水冷式发电设施，规模从50兆瓦到600兆瓦不等。目前，SBWR分配的循环水的盐度平均在780-800 mg/L之间，这被认为接近某些灌溉用途的盐度上限。因此，拟建发电厂排放的累积影响可能会使SBWR循环水不适用于各种工业、景观或农业用途，危及整个区域计划。 本文提出了一种基于盐分与作物产量、作物质量、园艺和工业用途之间的关系，以及对客户感知问题的定性评估来估计盐排放影响的方法。开发了物理和商业影响的经济评估，以及调节盐度以保护再生水质量的各种替代方法。本文试图量化总盐度和特定离子毒性对农业和景观灌溉以及工业再利用的累积影响。包括20个参考文献、表格和图表。

South Bay Water Recycling (SBWR) is a regional program that serves nonpotable recycled water to more than 300 irrigation and industrial customers in San Jose and Santa Clara and several other communities in the Silicon Valley area of northern California. Within the past two years, power companies have proposed building nearly a dozen water-cooled electrical generating facilities within the SBWR service area, ranging in size from 50 to 600 megawatts (MW). Currently, salinity of recycled water distributed by SBWR averages between 780-800 mg/L, which is considered to be near the upper limit of salinity for certain irrigation uses. As a result the cumulative impact of blowdown from the proposed power plants could make SBWR recycled water unsuitable for various industrial, landscape, or agricultural uses, jeopardizing the entire regional program. This paper presents an approach to estimating the impact of salt discharges based on relationships between salinity and plant yield, crop quality, horticulture, and industrial use, as well as a qualitative review of customer perception issues. An economic evaluation of physical and commercial impacts is developed, along with various alternative means of regulating salinity to protect recycled water quality. This paper attempts to quantify the cumulative impact of total salinity and specific ion toxicity on agricultural and landscape irrigation and industrial reuse.
