Abstract

The invention provides a river ecological reactor system, comprising a riparian ecological buffer strip, a plant reconstruction area, a water plant strip, zoobenthos and aquatic animals, wherein the riparian ecological buffer strip is constructed on the river bank, the plant reconstruction area is constructed on the river hydro-fluctuation belt, the water plant strip is constructed in the river, the zoobenthos and aquatic animals are stocked in the river. The invention also provides a method for constructing the river ecological reactor system. The construction method provided by the invention has low investment, is environment friendly, effectively accomplishes the unification of the three benefits of improving the water quality, enhancing the ecological functions and presenting landscapes, and has strong utility value as well as a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of ecological control, and in particular relates to a river ecological reactor system and a construction method thereof. Background technique [0002] Rivers are the water environment for human beings to survive, produce and live, and are the birthplace of human civilization. However, with the development of the economy, rivers are increasingly affected by human activities. In my country, with the acceleration of urbanization and the rapid increase of population, the discharge of sewage and wastewater has also increased rapidly, resulting in many urban rivers being affected to varying degrees. pollution. In the past 20 years, the state and local governments have invested a lot of manpower, material resources, and financial resources in water pollution control, and the surface water environment has improved to a certain extent. However, the "2009 China Environmental Bulletin" pointed out that China's surface...
