Water purifying composite ecological bed easy for plant management and recycling

Abstract

The invention provides a water purifying composite ecological bed easy for plant management and recycling. The water purifying composite ecological bed is characterized by comprising a pipe beam typewater purifying composite ecological bed body, an inflow water distribution area and an outflow water distribution area are arranged at two ends of the bed body and connected with a water incoming system and a water discharging system arranged on two sides of the bed body respectively, a porous PVC pipe is arranged in the bed body and used for planting aquatic plants, and a high-density polyethylene net is paved above the porous PVC pipe in a suspended manner and used for collecting dry branches and fallen leaves of plants and fixing the aquatic plants. The water purifying composite ecologicalbed is remarkable in water purifying effect, low in engineering difficulty and convenient for running management, and the problem that plants in conventional ecological beds are difficult to be managed scientifically at low cost is solved; on the basis of an advantage that plants in tube-bundle composite ecological beds are easy in management, the water purifying composite ecological bed can be used for purifying water and culturing plants having economic value at the same time so as to realize both environmental benefit and economic benefit.

Description

technical field [0001] The invention belongs to the technical field of environmental ecological engineering, is a sewage ecological treatment process with both landscape value and economic benefit, and in particular relates to a tube-bundle type water purification composite ecological bed which is easy for plant management and recycling. Background technique [0002] Artificial compound ecological bed is a kind of wastewater ecological treatment process. As a form of constructed wetland system, its purification of sewage is mainly through the interception and adsorption of wetland fillers, physical adsorption and extraction transformation of plant roots, adsorption of functional microorganisms on pollutants and three pathways of metabolism. Compared with traditional constructed wetlands, composite ecological beds tend to use porous and large specific surface area fillers as wetland substrates to increase the hydraulic load of the bed, and at the same time facilitate the atta...

AI Technical Summary

Problems solved by technology

The invention provides a tube-bundle type water-purifying composite ecological bed that is easy for plant management and recycling, and solves the problem that it is difficult to effectively recycle and remove plant litter and fallen leaves in the artificial ecological bed, and it is difficult to harvest and recycle aquatic plants with well-developed root systems at low cost. Difficulty, both environmental and economic benefits can be achieved by planting economically valuable plants in ecological beds
