Study on Clogging Mechanism and Control Methods of Artificial Recharge

摘要

The severe global fresh water shortage, the over-exploitation of groundwater and its related ecological environment geology problems, the global climate change, all of them are stimulating the study and practice of artificial recharge. But the clogging problem during artificial recharge is always to be the most common obstacle, it can reduce the recharge rate, increase the maintenance cost and shorten the longevity of the recharge facilities. The present paper analyzed the mechanism and characteristics of different clogging types, introduced the common methods for clogging control. Based on lots of experiments, a new method emphasis on engineering structure was proposed to prevent spread basin from clogging.
