Biotreatment technologies offer many advantages for passive stormwater treatment before harvesting, but performance can be variable and sensitive to system design, construction, operation and maintenance. While there is substantial research underpinning pollutant removal, hydraulic function, internal processes and optimal design, specific focus upon stormwater harvesting is relatively limited. Recent advances in system design include testing media amendments for targeted pollutant removal, enhanced pathogen removal using antimicrobial plants, and broadening technology application. However, the production of reliable fit-for-purpose water requires the development of robust validation methodologies to meet public safety expectations. While foundation studies exist, more needs to be done to extend the validation framework, monitor and control system performance and operation in real-time, and apply standards and regulatory checks.

雨水收集的生物处理技术：关键观点。

生物处理技术为收获前的被动雨水处理提供了许多优势，但是性能可能会变化并且对系统设计，构造，运行和维护敏感。尽管有大量研究支持污染物的去除，水力功能，内部流程和最佳设计，但对雨水收集的特别关注相对有限。系统设计的最新进展包括测试针对目标污染物去除的介质改良剂，使用抗微生物植物增强的病原体去除以及扩大技术应用范围。但是，要生产出可靠的适合用途的水，就需要开发可靠的验证方法来满足公共安全的期望。尽管已有基础研究，但仍需要做更多工作来扩展验证框架，
