Research progress on ecological restoration of water eutrophication.

The causes of water eutrophication and various common remediation methods, such as physical remediation' chemical remediation; bioremediation and compound remediation; were reviewed. The effects of different remediation methods on the treatment of N; P and other pollution factors in eutrophication of water bodies were analyzed; and the advantages and disadvantages of various remediation techniques were summarized. Based on the research progress of water eutrophication remediation technology; it is pointed out that bioremediation and composite remediation should be the main remediation technology, and physical and chemical remediation should be the supplementary remediation technology,and it is suggested that the combination of remediation technology and space technology can more effectively remediation and monitoring of water eutrophication pollution. In addition; remediation technologies such as algae-microbial fuel cells, which only control phosphorus but not nitrogen; have low cost and ideal effect, and are worthy of further study and application.
