饮用水回用
饮用水回用将处理后的污水净化至饮用水标准,或先经环境缓冲体再取用(间接饮用回用),或直接进入供水系统(直接饮用回用)。加州已于2023年通过直接饮用回用法规。
路线
Potable reuse relies on multiple independent treatment barriers plus extensive monitoring and operator certification. Full advanced treatment — ultrafiltration, reverse osmosis and UV advanced oxidation — is the widely validated core, sometimes augmented with ozone and biologically active carbon.
Singapore's NEWater program is the best-known large-scale reuse system; California's 2023 DPR framework and comparable efforts in Texas, Arizona, Australia and the Gulf mark the move from indirect to direct reuse as water scarcity intensifies.
