Problems solved by technology

At present, although there are many methods for landscape water treatment and restoration, they all have certain limitations and shortcomings.
For example, the physical method usually requires a lot of manpower and material resources, and the result is that the pollutants are often transferred from one area to another, which cannot fundamentally solve the problem, and the maintenance time is short, and the pollution is easy to recur; the chemical method infrastructure costs and operation The cost is high and it is easy to cause secondary pollution; although the biological method has a short treatment period and obvious effect, the effect is maintained for a short time and needs to be used repeatedly, and its separate use is relatively expensive; the artificial wetland restoration method is low in cost and can play a role in purification The function of water quality, but the

Embodiment 1

[0035] The invention is applied to a water quality improvement and ecological restoration project of a sightseeing lake in Hezhou City. The sightseeing lake is about 150m long from east to west, 50-70m wide from north to south, with an average water depth of 0.8-1.2m and a water surface area of ​​8420m 2 , the water volume is about 10,000 m 3 , is a relatively closed water body, the only source of water replenishment comes from the spring located in the east of the lake, and the pumping station drains out to the outer river every day, and the daily drainage is about 2000m 3 . Sightseeing lake water has poor sensory perception, low transparency, dark green lake water, black and odorous phenomenon locally, fishy smell from algae, main water quality index COD cr 、BOD 5 , TN are 61~80 mg / L, 13~18 mg / L, 2.64~4.11 mg / L respectively, which is inferior to Grade V water quality of surface water, and cannot meet the water quality standard for surface entertainment landscape.

Abstract

The invention relates to a closed or semi-closed landscape water body governance method including an aeration oxygen filling process, a biological treatment process and an artificial ecological reconstruction process; the biological treatment process includes adding microbial agents and biological growth-promoting agents; the artificial ecological reconstruction process includes bionic carbon fiber ecological grass and a compound ecological floating island technology; the water quality of the water body is improved by the aeration oxygen filling process and the biological treatment process; an ecological system is reconstructed and restored by the artificial ecological reconstruction process, and the water body landscape function is restored and promoted. The method can effectively improve the water quality of the water body, rapidly restores the water body ecological system and the self purification ability, and restores and promotes the water body landscape function; the water quality of the water body after governance achieves ''environmental quality standards for surface water'' (GB3838-2002) IV-class water standards. The method allows water quality improvement, ecological restoration and landscape promotion to be combined, has the characteristics of energy saving, good algae inhibiting effect, fast ecological restoration, low governance cost and the like, and has relatively good social benefits and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of water environment treatment, and relates to the technology for treatment of polluted water bodies, in particular to a method for treatment of closed and semi-closed landscape water bodies. Background technique [0002] Landscape water bodies such as lakes, rivers, and landscape pools are an important part of the urban water environment system. The environmental conditions of urban landscape water bodies are related to the healthy development of urban water ecology and landscape environment. However, with the development of cities and the acceleration of urbanization, a large amount of industrial wastewater and domestic sewage without effective treatment are discharged into urban rivers, lakes, reservoirs, landscape pools and other landscape water bodies, resulting in serious eutrophication of water bodies, black and smelly water bodies , Algae outbreaks are frequent, the water ecosystem is damaged to vary...
