Application of water ecological restoration guided by microbial activation in landscape water

Abstract

Water eutrophication is one of the difficulties in urban landscape water. In the past period of time, people have been exploring the prevention and control of eutrophication of landscape water. At present, submerged plant restoration, chemical control of algae and physical equipment filtration technology are becoming more and more mature. Among them, submerged macrophyte restoration has become the mainstream technology, but the restoration of submerged macrophytes is faced with the problem of lack of transparency, which leads to the failure of engineering construction. Indigenous microbial activation(IMA) technology has become an effective method to solve this problem. The technology focuses on the water microbial community as the research object. By adding an activator with a suitable concentration gradient to the experimental landscape water, the indigenous microbial community is activated landscape water. The paper analyzed the current landscape water eutrophication technology, summarized the relationship between bacteria and algae, algae and submerged plants, and proposed IMA microbial activation technology. In addition, we share a project case to better illustrate this technology.In the case, IMA equipment was added to the experimental landscape water to study the water environment quality changes before and after the implementation of the project, so as to evaluate the feasibility and technical advantages of IMA technology, and provide technical ideas and data support for landscape water treatment.
