Study on prevention algal bloom of urban lake and river

The eutrophication pollution of lake and rivers in cities has much negative impact on the water environment. Improving water quality by diminishing the algae is an important issue which can not be overlooked. This paper describes the physical, chemical and biological techniques for controlling algae, their shortcomings and the problems still in existence. The paper concludes that more effective control of algal bloom can be achieved by integrating different methods and through further study of more effective strategies.
