Abstract

The invention discloses a method for establishing a freshwater lake ecosystem, and belongs to the technical field of freshwater environmental pollution control. The method for establishing the freshwater lake ecosystem comprises the following steps of water quality improvement, water level maintenance, land-water interface treatment, bottom mud improvement, food network chain establishment, waterquality monitoring and the like, and an algae inhibitor throwing device is also arranged. Conditions for restoring the water ecosystem are established through combination of physics, chemistry and biology, and nitrogen and phosphorus pollutants in water are effectively degraded and absorbed by match of warm and cold plants, so that pollution load of a water body can be effectively reduced, the water body is purified, and the water ecosystem is stabilized. Aquatic plants and aquatic animals are thrown to construct a reasonable food network chain, and a plurality of aquatic plants and aquatic animals can exert a synergistic effect, so that the effect is more obvious compared with the effect of singly planting aquatic plants or singly throwing aquatic animals, transparency of the water body is improved, nutrient salts are reduced, and construction and restore of the water body ecosystem are facilitated.

Description

technical field

[0001] The invention relates to the technical field of freshwater environmental pollution control, and more specifically, relates to a method for establishing a freshwater lake ecosystem. Background technique

[0002] With the development of industry, the continuous improvement of people's living standards, and the continuous deterioration of the global environment, the control of water pollution and the improvement of the ecological environment have entered a relative bottleneck period; the water cycle system is fragile, the quality of the water environment is declining, and the water function is degraded. Research on urban sewage collection and treatment, surface runoff pollution control, urban water function restoration, and water body ecological landscape construction. A series of advanced water pollution control, ecosystem construction and restoration, and waterscape optimization technologies have been developed for urban rivers, water supply reservoirs,...
