Embodiment 1

[0043] Shuanggang Village is located in the north of Liuxi River, Jianggao Town, Baiyun District, Guangzhou City, and the Xinguanghua Highway passes through the village. There is a large Fengshui pond in Shuanggang Village. The area of the Fengshui pond is about 9 mu, the water depth is about 1.3m, the thickness of residual mud is about 80cm, and the total water volume is about 8000m 3 , belongs to a beautiful scenery in the village, and has an extraordinary status to the entire water environment in the village. However, due to the erosion of rainwater, the dirt on the surface will be brought into the water body, and the sewage discharge of some surrounding residents will also increase the amount of sludge in the pond, and continuously release pollutants into the water body. If there is no water circulation system, oxygenation and other facilities, it belongs to "dead water". If there is no artificial intervention to implement ecological purification measures, it is difficul...

Embodiment 2

[0058] Luhu Park is located in Baiyun Mountain Scenic Area, Guangzhou. The water area of Luhu Park's main lake landscape lake is about 290 mu. The water depth in the shallow water area is 1m, the water depth in the deep water area is 6m, and the deepest silt can reach 2m. The water quality is yellow and the visibility is less than 20cm. The water area is large, the silt is thick, and the fluidity of the water body is poor. Without artificial intervention to implement ecological purification measures, it is difficult to maintain good water quality only by the self-purification ability of the water body in the lake. Therefore, taking the main landscape lake body of Luhu Lake Park as an example, the method of the present invention is used to realize the construction of the landscape lake water ecosystem to maintain its water quality, as follows:

Abstract

The invention relates to the field of pollution control of water environments. Aiming at the problem of low self-cleaning capability of a landscape lake, the invention provides a construction method of a water ecological system of the landscape lake. The method comprises the following steps of S1, pretreatment of lake water: putting microbes and zooplanktons into the lake water; S2, construction of an aquatic plant system: planting aquatic plants; S3, construction of an aquatic animal system: after the planting of the aquatic plants is completed, putting aquatic animals into the lake water; and S4, later-stage maintenance: regularly harvesting the aquatic plants and catching the aquatic animals. Firstly, the microbes and the zooplanktons are added into the lake water, and the microbes adsorb and decompose organic substances in the lake water, so that nutrient substances such as ammonia, nitrogen and phosphorus in water can be favorably reduced, and water body transparency is improved;the zooplanktons are favorable for the decomposition of blue-green algae in the lake water; a better environment is favorably provided for the growth of the aquatic plants; the survival rate of the aquatic plants is favorably improved; and the self-repairing capability and self-purification capability of a water body are enhanced.

Description

technical field [0001] The invention relates to the field of water environment pollution control, more specifically, it relates to a method for constructing a landscape lake ecosystem. Background technique [0002] Landscape lakes are generally artificial lakes, which are a kind of lake dug out by people in a planned and purposeful manner, and are produced in an unnatural environment. The landscape lake provides the city with a suitable landscape atmosphere and is conducive to improving the quality of the urban environment. [0003] However, as an open system, the landscape lake will inevitably be challenged by various pollution factors, mainly including the following aspects: 1. Atmospheric dry and wet deposition: the air pollution is becoming more and more serious, and the nutrients in the atmosphere will be accompanied by dust and rain. Into the lake, so that nutrients such as COD, nitrogen, phosphorus, etc. are brought into the water to dissolve, affecting the water qua...
