Abstract

Drinking water sources have higher water quality requirements because of their special uses. Many drinking water sources in the world have been polluted or are being polluted for a long time, resulting in eutrophication. We define the approaches that have been developed in the last 10 years and achieved good effect as innovative restoration approaches. In this paper, the traditional, and frequently used restoration approaches in recent 30 years were briefly reviewed, and the innovative technologies and methods were summarized and evaluated in detail. In light of the impact of COVID-19, we have also put forward rational suggestions on water quality restoration of transboundary rivers to provide scientific reference for global public health safety and protection.
