A biomass carbon-based multifunctional floating wetland system

Abstract

The invention discloses a biomass charcoal-based multifunctional floating wetland system for repairing contaminated water bodies, comprising: a sponge charcoal floating bed; a fixed net; a fixing device; a biomass charcoal electrode; an LED lamp; Electrode biofilm device below the floating bed. The invention adapts to the stable requirements of different water conservancy conditions, can be applied to repair various water bodies such as river channels, and can effectively reduce the content of pollutants such as nitrogen, phosphorus, organic matter and other pollutants in the water body; the biomass-based sponge charcoal used in the invention not only avoids the use of additional buoyancy It can also promote the growth of wetland plants, solve the problem of low survival rate of traditional floating bed plants, and the floating body is easy to cause secondary pollution, quickly build a water ecological landscape, and improve environmental effects; the present invention can generate electricity while removing pollutants. LED lights emit light without additional power consumption; and the floating wetlands can grow commercial crops, increase economic value, and have obvious economic benefits.

Description

technical field [0001] The invention relates to the fields of waste biomass recycling and polluted water treatment, in particular to a biomass carbon-based multifunctional floating wetland system. Background technique [0002] With the rapid development of China's economy and society, the discharge of domestic sewage has increased rapidly, and the problem of river water pollution has become increasingly prominent; at the same time, the excessive application of pesticides and fertilizers in agriculture will flow into the river with surface runoff, causing nitrogen, phosphorus and organic matter in the river. Exceeding the standard, causing water eutrophication. Floating wetlands are an effective eutrophic water restoration technology, and are widely used in river restoration. Traditional floating wetlands take plants as the main body, and absorb nutrients such as nitrogen and phosphorus in the water body through the root system of plants to achieve the purpose of purifying t...
