Embodiment Construction

[0022] The domestic sewage treatment pilot system in the South China Botanical Garden of the Chinese Academy of Sciences (near the domestic sewage outlet of the Ballet Troupe) is planted with screened and domesticated plants of coix coix, water ghost banana, white ginger flower, heliconia chinensis, sedge, and chrysanthemum rush. The total planting area 200m 2 , plant bed area 100m 2 . The daily sewage treatment volume is 40m 3 , TN, TP, COD Cr 、BOD 5 Removal rates of 45%, 80%, 80% and 85% respectively, the effect is good.

Abstract

A method for cleaning the life sewage features that the artificial wetting area is created and different kinds of plants suitable for the artificial wetting area are chosen for higher cleaning effect.

Description

technical field [0001] The invention relates to plant treatment technology for domestic sewage in environmental ecological engineering. Background technique [0002] Constructed wetland is an ecosystem built by using engineering measures to simulate natural wetlands for wastewater treatment. It is mainly composed of media, plants and microorganisms. It mainly uses the physical, chemical and biological triple synergies of substrate-aquatic plants-microbes in the system. , through matrix filtration, adsorption, precipitation, ion exchange, plant absorption and microbial decomposition to achieve efficient purification of sewage. Plants in constructed wetlands can absorb and enrich pollutants, provide energy, beautify the landscape, and provide habitats for microorganisms, which play an important role. At present, developed countries such as Europe and the United States use artificial wetlands to purify domestic and industrial sewage, which has very good ecological and economic...
