Description

Landscape water body ecological system and construction method thereof

Technical Field

The application relates to the technical field of water environment protection, in particular to a landscape water body ecological system and a construction method thereof.

Background

Landscape water bodies, such as artificial lakes, urban landscape riverways, park water areas and the like, become important components of urban modern construction, are effective measures for improving the environment and enhancing the landscape, and make prominent contribution to urban and rural sustainable development.

Because most of urban landscape water bodies are in a closed or semi-closed state and generally lack fluidity, sunlight directly irradiates the water bottom, the water temperature is easy to rise, and good natural conditions are created for mass propagation of algae and other plankton. On the other hand, as an important place for daily leisure and entertainment of people, ornamental fishes such as koi, goldfish and the like are generally cultured in urban landscape water, the excrement of animals, garbage thrown by citizens, bait thrown into the urban landscape water and the like become main exogenous pollution of the landscape water, and the nutritive salts are the material basis for causing eutrophication of the landscape water.

At present, in order to solve the problem of landscape water eutrophication, methods which are commonly adopted comprise a physical method, a chemical method, a biological method and the like.

The physical methods comprise clear water diversion, aeration and oxygenation, water body filtration and decontamination and the like, but the symptoms are usually treated but not the root causes, and the self-purification capacity of the water body is not effectively recovered.

The chemical method generally comprises the steps of adding various chemical agents into the water body, such as adding the chemical agents to kill algae, adding ferric salt to promote phosphorus precipitation, adding lime to denitrify and the like, but the method is easy to cause secondary pollution, has higher operation cost and is usually used as an emergency measure for dealing with sudden water body pollution.

The biological method generally establishes an ecological floating island on the water surface, removes pollutants such as nitrogen, phosphorus and the like in the polluted water body by planting aquatic plants on the ecological floating island and utilizing the root absorption and adsorption effects of the aquatic plants, inhibits the excessive growth of algae in the water body and has the advantage of beautifying the water body landscape.

At present, in order to recover the self-purification capacity of the water body fundamentally, a scheme of combining a physical method and an ecological method is generally adopted to treat the scenic water body, and the ecological floating island is established in the water body to eliminate pollutants such as nitrogen, phosphorus and the like in the water body, so that the self-purification capacity of the water body is recovered. Before the self-purification capacity of the water body is recovered, the water body is filtered and purified, and algae and solid impurities in the water body are removed, so that the recovery speed of the self-purification capacity of the water body is accelerated.

When carrying out filtration purification to the water, generally utilize the suction pump in with the water suction filter equipment that receives the pollution, through being equipped with stone grain layer and active carbon layer at filter equipment, the alga solid impurity that contains in the water is strained by the filter to depend on stone grain layer, the active carbon layer contains partial soluble impurity absorption in with the water, make the water after the filtration comparatively clarify, later with the water discharge after the filtration to the landscape water in, thereby improve water quality, in order to accelerate the recovery rate of water self-purification ability.

With respect to the related art among the above, the inventors consider the following drawbacks: because of the large amount of landscape water, the algae and solid impurities contained in the water are more, therefore the stone particle layer needs to be frequently replaced and cleaned, so that the filtering device keeps good filtering effect, and the working strength of the working personnel is high.
