Method for reconditioning water body in eutrophication through plants

Abstract

A process for treating the nutrients-enriched water features that the chosen different plants are fixed to the self-floating braided objects, floating the braided objects on water surface for growing said plants to absorb nutrients, and collecting the plants. Its advantages are high effect etc.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and greening. It specifically relates to a phytoremediation and plant landscape construction technology for eutrophic water bodies. Background technique [0002] Eutrophication of water body is a major environmental problem worldwide. Since the 1970s, the problem of lake water pollution in my country has gradually emerged. With the development of the economy and the passage of time, the problem of eutrophication has become increasingly serious. So far, 90% of the lakes in our country have been or tend to be eutrophic, which poses a serious threat to the sustainable development of the ecological environment, urban landscape and social economy. How to effectively control the eutrophic water body is a realistic problem that we must face. [0003] The treatment of existing water eutrophication can be mainly classified into physical, chemical and biological methods. Because the firs...

Problems solved by technology

Among them, phytoremediation technology has become the most ideal choice for bioremediation of eutrophic water body because of its safety, cheapness, easy manual operation, and certain environmental aesthetic value. However, there are still many limitations in practical application, making it difficult to apply effectively. It is: 1. Submerged plants are often difficult to grow well in eutrophic water bodies. Emergent plants generally can only grow in shallow water areas, and floating plants often form single-optimal communities on the water surface, which is harmful to aquatic ecosystems and biodiversity. 2. It takes a lot of manpower and material resources to collect plants for restoration; 3. It is difficult to form a suitable combination of plant communities and a better plant landscape
