Background technique

In recent years, the frequent occurrence of microalgae or microalgae-type harmful algal blooms in many offshore and inland lakes and other water bodies has brought a variety of hazards to the water landscape, aquatic economy, and even the health of residents. To develop and protect the life safety of residents, there is an urgent need for effective emergency prevention and control measures for harmful algal blooms. By spraying harmful algal bloom elimination agents such as modified clay, the purpose of quickly eliminating excess microalgae or microalgae in the water body and reducing or eliminating the harm of harmful algal blooms can be achieved. Over the past decade, there have been many successful cases of controlling or eliminating large-scale harmful algal blooms by spraying modified clays.
