Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0027] The materials used in the following examples are all commercially available.

[0028] Implementation Example 1

[0029] The landscape water body of a lake in a park covers an area of ​​18,000 square meters and the water capacity is 20,000m 3 , water quality COD40mg / L, ammonia nitrogen 3.5mg / L, total phosphorus 0.09mg / L, transparency 30cm. The lake landscape water body is treated jointly by the bypass enhanced treatment technology and the in-situ ecological restoration technology of the water body. BAF is located in the lake bypass, aquatic plants are planted in the lake at a water depth of 0-50cm, spherical carbon fiber composite filler (see utility model patent ZL201520888024.5) is placed in the lake at a water depth exceeding 80cm, and carbon steel is used to fix the spherical carbon up and down ...

Abstract

The invention belongs to the technical field of water body remediation, and discloses a water quality maintenance and ecological remediation method for a lake landscape water body, particularly a method for treating the lake landscape water body with the combination of a bypass enhanced treatment technique and a water body in-situ ecological remediation technique. According to the water quality maintenance and ecological remediation method, an aeration biological aerated filter system, an aquatic plant treatment system and a spherical carbon fiber combined packing treatment system are adopted for united treatment. By adopting the method disclosed by the invention, enhanced treatment and ecological remediation are integrated, defects of a single technique can be made up, a lake ecological system can be weak if a bypass treatment system is independently used, the treatment capacity can be limited if an ecological remediation technique is independently used, the bypass treatment system and the ecological remediation technique are organically combined, suspended solids can be reduced by using spherical carbon fiber combined packing, the blocking of an aeration biological aerated filter can be reduced, meanwhile a good environment can be provided due to the spherical carbon fiber combined packing after pollutants are removed, conditions suitable for microorganisms to live can be provided, a stable ecological system can be reconstructed, and the water quality of a lake can be effectively maintained for a long time.

Description

technical field [0001] The invention belongs to the technical field of water body restoration, and in particular relates to a method for water quality maintenance and ecological restoration of a lake landscape water body, specifically using a bypass enhanced treatment technology and a water body in-situ ecological restoration technology to jointly treat the lake landscape water body. Background technique [0002] Most of the lake landscape water bodies are distributed in parks, large residential areas and other places. They can not only beautify the environment, but also carry water circulation, regulate the urban ecological environment and solve the urban heat island effect. Its important and special landscape value and practical function value And the ecological value is getting more and more attention and attention, and the urban artificial landscape water surface is also more and more serving the daily life of the public. [0003] The main characteristics of urban lake l...
