Problems solved by technology

[0003] However, due to the unreasonable design of wetland parks: some only focus on the reduction of COD, TN, and TP by wetlands, while ignoring the restoration of water ecosystems and the role of landscape; some even overemphasize the role of landscape and ignore All in all, it is impossible to form a complete set of feasible technical solutions that integrate water purification, water ecological restoration and landscape, and wetland technology has gradually become "chicken ribs".

Embodiment Construction

[0034] Such as Figure 1 to Figure 5 Shown, be the construction method of a kind of lake water purification system of the present invention, comprise the steps:

[0035] (a) Site survey: Professionals operate the submersible pump to clean up the underwater garbage first, then clear the weeds on the edge of the lake bank, repair the subsidence of the lake bank, and do a good job of slope protection. According to the design elevation of the lake surface, a width of 0.3 is reserved at the edge of the lake bank. ~1.8m buffer zone, the buffer zone becomes undisturbed growth and shelter for wild animals and plants. And investigate the water quality, terrain and soil factors in the lakeshore area, screen out the aquatic plants and herbaceous plants that are suitable for the growth of the lakeshore area, and eliminate the enrichment in the water body through the absorption, adsorption and species competition mechanism of plant roots. Nitrogen, phosphorus and harmful substances, so as...

Abstract

The invention discloses a construction method of a lake water purification system. The method includes the steps of: (a) site surveying; (b) site construction; (c) precipitation zone configuration; (d) aeration zone configuration; (e) compounding zone configuration; (f) ecological planting zone configuration; (g) floating island unit establishing; and (h) regional beautification. The method provided by the invention has the advantages of simple construction, short construction period and cost saving, and after construction, the purification system has the functions of water storage, flood control, and water and air purification, can protect biodiversity, adjust microclimate and improve environmental quality, thus laying the foundation for water quality improvement of regional lake water.

Description

technical field [0001] The invention belongs to the technical field of water body purification, and in particular relates to a construction method of a lake water body purification system. Background technique [0002] At present, for the treatment of "black and odorous" water bodies, many wetland treatment technologies have emerged. Constructed wetlands are a composite process that combines natural purification and artificial enhancement. It can adopt an appropriate scale according to the amount of sewage. Use the purification effect of wetlands to improve the water quality of water bodies, and then eliminate black and odor. Compared with traditional secondary biochemical treatment, constructed wetland has the advantages of low construction and operation costs, simple maintenance, good effluent quality and strong adaptability to load changes, etc., and is more suitable for small towns with low technical management level and small scale Or rural sewage treatment. On the pr...
