Embodiment 1

[0026] Example 1 Longtan West Lake Ecological Restoration Experimental Area

[0027] The water body of Longtan West Lake in Beijing is replenished with recycled water, and the algae in the water thrive, mainly cyanobacteria. The ecological restoration test area covers an area of ​​50 square meters, and is sealed around with waterproof cloth. The bottom is the undisturbed sediment of the lake bottom, which is not closed. The depth of the water body in the restoration area is 0.6-1.0 meters, and the volume of the water body is 30-50 cubic meters.

[0028] The planting varieties of submerged plants are mainly foxtail algae, black algae, hornwort, belacanthus, perforatum, longanus, and microdentate, with a planting area of ​​about 50%; emergent plants It is mainly cattail grass, and there is a small amount of reed in the water body, with a planting area of ​​about 10%; floating and floating leaf plants include water chestnut and water chestnut, with a planting area of ​​about 2%. ...

Abstract

The invention relates to a method for restoring a river/lake water system by biological chain construction technology, which is implemented by constructing a biological chain system in a river/lake water system, wherein the biological chain system is composed of submerged plants, emerging plants, floating plants, floating leaf plants, aquatic animals and zooplankton. The method avoids disturbance and damage of physical or chemical technology to the water body, and is suitable for a river/lake water body with a damaged or unsound water system ecological structure. The river/lake water body treated by the biological chain construction technology is close to the natural water body; and the ecological function is gradually recovered, and the self-purification capacity is gradually improved. In addition, the method is simple to operate, has the advantages of investment saving and no pollution, and does not occupy the extra space except the river/lake water body, thereby saving the land.

Description

technical field [0001] The invention relates to a water body restoration technology, in particular to a river and lake water system biological chain construction technology. Background technique [0002] The original ecosystem of the river and lake water system, also known as the original purification system, is composed of gravel, riverbed and bank materials existing in it, and aquatic plants, zooplankton, benthic animals and large aquatic plants growing in it. This system has a certain water purification ability, which can dilute and decompose foreign pollutants. However, with the increasingly serious pollution of river and lake water bodies, the original purification system is destroyed, and the original purification ability of the river and lake water system gradually weakens; when the external pollution reaches a certain level, the purification ability of the original purification system disappears completely, and then With the accumulation of pollution, the degree of ...
