Artificial wet land plant distribution for purifying domestic sewage

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...

Problems solved by technology

These plants are relatively unattractive, and they are planted with a certain plant as the unit plot. After a certain period of time, the substrate will be blocked and the purification effect will be reduced.
