Biomass charcoal-based multifunctional floating wetland system

Abstract

The invention discloses a biomass charcoal-based multifunctional floating wetland system for repairing a dyeing water body. The biomass charcoal-based multifunctional floating wetland system comprisesa sponge carbon floating bed, a fixing net, a fixing device, a biomass charcoal electrode, an LED lamp, plants and an electrode biological membrane device arranged below the sponge carbon floating bed. According to the invention, the biomass charcoal-based multifunctional floating wetland system adapts to stability requirements of different water conservancy conditions, can be applied to restoration of various water bodies such as riverways and the like, and can effectively reduce the content of pollutants such as nitrogen, phosphorus, organic matters and the like in the water bodies; the biomass-based sponge carbon adopted by the invention not only avoids the use of extra buoyancy components, but also can promote the growth of wetland plants, solves the problems of low survival rate of traditional floating bed plants and easy secondary pollution caused by a floating body, quickly constructs a water ecological landscape, and improves the environmental effect; electricity can be generated for a LED lamp to emit light while pollutants are removed, so that extra power consumption does not need to be increased; and economic crops can be planted in the floating wetland, so that the economic value is improved, and the economic benefit is obvious.

Description

technical field [0001] The invention relates to the field of recycling of waste biomass and treatment of polluted water bodies, 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 sharply, and the problem of river water pollution has become increasingly prominent; at the same time, the excessive use of pesticides and fertilizers in agriculture will flow into the river with surface runoff, causing the nitrogen, phosphorus, and organic matter in the river to increase. Exceeding the standard will cause eutrophication of the water body. Floating wetlands are a relatively effective technology for eutrophic water restoration and are widely used in river restoration. Traditional floating wetlands use plants as the main body, and absorb nutrients such as nitrogen and phosphorus in the water body through the plant root s...
