Method for improving water environment of landscape water

Abstract

The method discloses a method for improving a water environment of landscape water. The method comprises steps as follows: control of outer pollution around a target water body and improvement of thewater environment of the target water body are carried out, wherein control of the outer pollution around the target water body comprises steps of construction of close-to-nature revetments and building of coastal vegetational zones; the improvement of the water environment of the target water body comprises steps as follows: a water lifting type fountain aerator and a microflow circulating pump are arranged in the landscape water body and used for detecting concentration of dissolved oxygen in the water body; total water, nitrogen content and phosphorus content of the target water body are measured; a symbiotic system is constructed; a small micro-ecosystem is established; a food web system is established. Compared with the prior art, the method has beneficial effects as follows: the method is simple and flexible, transparency of the landscape water can be improved remarkably, content of COD, ammonia nitrogen, total nitrogen and total phosphorus of the landscape water are remarkably reduced, and quality of the landscape water and landscape environment are improved.

Description

technical field [0001] The invention belongs to the technical field of water body ecological restoration methods, in particular to a method for improving landscape water environment. Background technique [0002] Landscape water generally refers to water bodies used for visual viewing, and is usually divided into two categories: one is natural water features, such as natural rivers and lakes; the other is urban landscape water, such as artificial lakes, landscape ponds, and landscape pools. As people's pursuit of living environment is getting higher and higher, especially urban residents are more and more yearning for clean air and comfortable environment. In order to make urban life more beautiful, the government and other relevant enterprises have established more and more urban landscape water systems. However, due to the fact that urban landscape water bodies are mostly static or closed slow-flowing water bodies with poor fluidity, and the water area is small, easily po...

Problems solved by technology

However, due to the fact that most of the urban landscape water bodies are closed and slow-flowing water bodies with static or poor mobility, and the water area is small, easily polluted, the water environment capacity is small, and the self-purification ability of the water body is low, coupled with the impact of residents' lives and fish in the water system, It is very easy to cause the increase of suspended solids, turbidity, organic matter, bacteria and Escherichia coli in the water

When the temperature is high, a large number of algae will grow in the water body rich in N, P and other nutrient elements, and the abnormal reproduction of algae will destroy the ecological balance of the urban landscape water body, resulting in an increase in the chroma of the water body, and even the color of the water body is black. Smell and other problems, thus losing the function of the landscape water body, so the improvement and governance of the water environment of the urban landscape water body is urgent
