Problems solved by technology

When the temperature is high, a large number of algae will grow in the water 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 urban static landscape water bodies, including exogenous pollution control around the target water body and water environment improvement for the target water body;

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

[0024] The first step is to build revetments 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.

[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 pollutants, but also...

Embodiment 2

[0035] A method for improving urban static landscape water bodies, including exogenous pollution control around the target water body and water environment improvement for the target water body;

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

[0037] The first step is to build revetments 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.

[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 intercepting pollutant...

Embodiment 3

[0048] A method for improving urban static landscape water bodies, including exogenous pollution control around the target water body and water environment improvement for the target water body;

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

[0050] The first step is to build revetments 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 pollutant...

Abstract

The invention discloses a method for improving an urban static landscape water body. The method comprises the steps: carrying out exogenous pollution control on the periphery of a target water body, and carrying out water environment improvement on the target water body, wherein the exogenous pollution control conducted on the periphery of the target water body comprises: building near-natural revetment and arranging coastal plant zone, and the environment improvement conducted on the target water body comprises: arranging a water lifting type fountain aerator and a micro-flow circulating pumpin a landscape water body, and detecting the dissolved oxygen concentration of the water body; determining the total water amount of the target water body and the nitrogen content and the phosphoruscontent in the target water body; constructing a symbiotic system; constructing a small micro-ecological system; and constructing a food web system. Compared with the prior art, the method of the invention has the beneficial effects that the method is simple, flexible and variable, and can significantly improve the transparency of the landscape water, significantly reduce the COD content, the ammonia nitrogen content, the total nitrogen content and the total phosphorus content of the landscape water and improve the water quality and the landscape environment of the landscape water.

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] Due to the fact that most of the urban landscape water bodies are static closed water bodies, 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 influence of residents' lives and fish in the water system, it is easy to cause the increase of suspended solids in the water , turbidity increased, the content of organic matter, bacteria and E. coli all increased. When the temperature is high, a large number of algae will grow in the water 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 co...
