[0002] With the rapid development of economy, the total amount of urban sewage discharge is increasing, and the sewage treatment rate fails to grow synchronously, and a large amount of wastewater directly enters various water bodies without treatment, which exceeds the purification limit of the water body itself, leading to more and more serious damage to the water ecological system, and water quality shortage has become a relatively common water ecological disaster. Since lakes and reservoirs are closely related to human life, the current serious river and lake water pollution and water quality deterioration have seriously affected the development of society and the production and life of people. Water ecological restoration has become a serious challenge faced by mankind at present, and how to improve the water restoration method, optimize the water restoration technology and process, reduce the capital investment and operation cost of water ecological restoration, reduce the energy consumption in the process of water ecological restoration, improve the comprehensive efficiency of water ecological restoration, and be applied and popularized in actual life has become a very urgent task.

[0003] At present, among various means of water ecological restoration, water plant ecological restoration technology is widely researched and applied due to the advantages of low energy consumption, good effect and low operation cost. The water plants used in the water plant ecological restoration technology mainly include four types: submerged plants, emergent plants, floating plants and floating leaf plants, wherein the submerged plants play a major role in water purification, accounting for about 80%, and the emergent plants account for about 10%, the submerged plants can absorb a large amount of pollutants in the water body in the growth process, and the excessive nutrients in the water body can be transferred by harvesting the submerged plants, the submerged plants can also provide carriers for the purification process through photosynthesis, regulate the position circulation speed of the water ecological system, increase the biodiversity of the water body, control the growth of algae, and the growth of the submerged plants is a key to the success of a water ecological restoration engineering project.

[0004] However, for heavily polluted water bodies with large water area, large water depth and low transparency, many submerged plants not only are difficult to plant and construct due to the limited sunlight irradiation in deep water and the influence of herbivorous wild fish and other factors, but also cannot grow well, and in addition, it is difficult to maintain and manage in the later period, so it is difficult to achieve the purpose of purifying water quality and balancing ecology.
