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

Embodiment 1

[0022] A method for improving the landscape water environment, including controlling external source pollution around the target water body and improving the water environment of the target water body;

[0023] Exogenous pollution control around the target water body includes the following steps:

[0024] The first step is to build a revetment close to the nature: use a gentle slope to reduce the erosion of water runoff, and the gentle slope is paved with pebbles of different sizes. The purpose is to restrain the erosion of the revetment due to the rainstorm runoff.

[0025] The second step is to set the shore plant belt: the shore plant belt is set in the shallow water area of ​​the shore, and the width is 1m. Emergent plants are planted on the shore plant belt, such as lotus, canna, reed, cattail grass, cress etc., and set wooden stakes on the shore plant belts to control the growth range of emergent plants. These emergent plants not only have the effect of intercepting po...

Embodiment 2

[0035] A method for improving the landscape water environment, including controlling external source pollution around the target water body and improving the water environment of the target water body;

[0036] Exogenous pollution control around the target water body includes the following steps:

[0037] The first step is to build a revetment close to the nature: use a gentle slope to reduce the erosion of water runoff, and the gentle slope is paved with pebbles of different sizes. The purpose is to restrain the erosion of the revetment due to the rainstorm runoff.

[0038] The second step is to set up the coastal plant belt: the coastal plant belt is set in the shallow water area of ​​the bank, and the width is 1.2m. Emergent plants are planted on the coastal plant belt, such as lotus, canna, reed, cattail grass, cress, etc. , and set wooden stakes on the shore plant belt to control the growth range of emergent plants. These emergent plants not only have the effect of inte...

Embodiment 3

[0048] A method for improving the landscape water environment, including controlling external source pollution around the target water body and improving the water environment of the target water body;

[0049] Exogenous pollution control around the target water body includes the following steps:

[0050] The first step is to build a revetment close to nature: use gentle slopes to reduce water runoff erosion, and the gentle slopes are paved with pebbles of different sizes. The purpose is to restrain the erosion of the revetment due to the rainstorm runoff.

[0051] The second step is to set up the coastal plant belt: the coastal plant belt is set in the shallow water area of ​​the bank, and the width is 1.5m. Emergent plants are planted on the coastal plant belt, such as lotus, canna, reed, cattail grass, cress, etc. , and set wooden stakes on the shore plant belt to control the growth range of emergent plants. These emergent plants not only have the effect of intercepting p...

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...
