在高强度降水期间，下水道可能会变得水力超载，导致未经处理的水进入接收流。联合（民间组织）和卫生下水道溢流（SSO）造成不利的公共卫生和环境影响，以及许多废水公用事业的管理挑战。这篇新颖的综述介绍了有关潮湿天气流量调节、影响和当前管理方法的信息，并为美国未来的方法提供了思路。目前，通常采用在降水事件后储存，然后进行常规市政水回收设施处理。独立的替代技术包括高速固体去除、快速消毒、过滤和绿色基础设施。然而，目前大多数独立的方法并不能解决雨水和废水中的可溶性BOD 5或新出现的污染物。随着潮湿天气流量管理需求的变化，未来的方法应包括零溢流的目标，并实现与传统处理一样好或更好的污水质量。为了帮助实现零溢流和完全处理，提出了“峰值设施”的概念。峰化设施通常保持空闲，但在需要时处理多余的流量。考虑到长时间闲置、快速启动和处理高流量的挑战，化学氧化可能是一种适用的调峰设施组件。然而，需要进行更多的研究和开发，以确定最佳做法。
Sewers can become hydraulically overburdened during high‐intensity precipitation resulting in untreated water entering receiving streams. Combined (CSOs) and sanitary sewer overflows (SSOs) cause adverse public health and environmental impacts as well as management challenges for many wastewater utilities. This novel review presents information regarding wet weather flow regulation, impacts, and current management methods, and offers ideas for future approaches in the United States. Currently, storage followed by conventional municipal water reclamation facility treatment after precipitation events is often employed. Stand‐alone alternative technologies include high‐rate solids removal, rapid disinfection, filtration, and green infrastructure. However, most current stand‐alone approaches do not address soluble BOD5 or emerging contaminants in stormwater and wastewater. As the needs for wet weather flow management change, future approaches should include a goal of zero overflows and achieve effluent quality as good as or better than conventional treatment. To help achieve zero overflows and complete treatment, the “peaker facility” concept is proposed. The peaker facility often remains idle but treats excess flow when needed. Considering the challenges of remaining idle for long periods, starting up quickly, and handling high flows, chemical oxidation may be an applicable peaker facility component. However, more research and development are needed to determine best practices.
