Problems solved by technology

[0002] At present, the treatment of zinc-contaminated water bodies is mainly carried out by adsorption method and microbial method, but the cost is high, energy consumption is large, operation is difficult, and secondary pollution is easy to occur. In addition, phytoremediation technology is used. Alien invasive species hide ecological crisis; others, such as cattails and reeds, have limited treatment capacity, so now there is an urgent need for a method with low cost, no secondary pollution, and strong ability to restore zinc-polluted water bodies

Abstract

The invention relates to a method for repairing zinc-contaminated water by use of aquatic plant water lily. The method adopts selection, pretreatment, adaptive growth, planting and testing to repair zinc-contaminated water; the adopted aquatic plant species is water lily which belongs to the native dominant plant and has the characteristics of long growth period, strong adaptation and excellent landscape effect and the like, the selected plant can effectively protect the native aquatic plants and can prevent introduced species from invasion, and the whole process is environmentally friendly and pollution-free and has the advantages of low expense, high treatment efficiency and strong operability; and the aquatic plants can form a waterscape, appropriate planting density is adopted to achieve the repairing purpose of the water contaminated by zinc with different concentrations, the water ecosystem is beneficially restored and remarkable social and ecological benefits are achieved.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a method for repairing zinc-polluted water bodies by using aquatic plants water lilies. Background technique [0002] At present, the treatment of zinc-contaminated water bodies is mainly carried out by adsorption method and microbial method, but the cost is high, energy consumption is large, operation is difficult, and secondary pollution is easy to occur. In addition, phytoremediation technology is used. Alien invasive species hide ecological crisis; others, such as cattails and reeds, have limited treatment capacity, so there is an urgent need for a method with low cost, no secondary pollution, and strong ability to restore zinc-polluted water bodies. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a water lily repairing water plant that is simple in design, easy to use, l...
