Description
Technical field
It is the ecological wastewater processing for having both landscape value and economic benefit the invention belongs to ecological engineering of environment technical field
Technique more particularly to a kind of being easy to plant regulatory and the tube bank type water purification of recycling is composite ecological bed.
Background technology
Flow Pattern of Constructed Wetland is a kind of ecological wastewater processing technique, net as a kind of form of artificial wet land system
Change sewage mainly by the retention of wet land filler and absorption, the physical absorption of plant root and extraction conversion, functional microorganism pair
Three kinds of approach of absorption and metabolism of pollutant.Traditional artificial wetland is compared, it is composite ecological bed to tend to use porous and specific surface
The big filler of product improves the hydraulic loading of bed as Wetland Substrate, while being conducive to the attachment and training of Wetland Function microorganism
It supports.The Planting pattern system by optimizing wetland plant has stronger from reoxygenation ability, is conducive to efficiently remove nitrogen, phosphorus
It removes.In addition, the system structure optimization based on sewage disposal demand can make Flow Pattern of Constructed Wetland simultaneously to nitrogen, phosphorus, heavy metal and
Some Organic Pollutants have higher removal efficiency.Due to Flow Pattern of Constructed Wetland purifying water effect significantly, engineering difficulty compared with
Low, operational management conveniently, therefore is a kind of efficient ecological recovery scenario easy to spread.
Important component of the water plant as Flow Pattern of Constructed Wetland is the major embodiment of ecological bed landscape composition,
Except with can purify water and mainly pass through in addition to appreciating：(1) the direct absorbed nitrogen of root system, phosphorus, heavy metal and there are many machine pollute
Object is then converted into itself needed nutrient matter or nontoxic intermediate product in metabolic pathway, is enriched in organizer by transhipment
Official, or be transported in air by phytovolatilization；(2) flourishing root system provides attachment site, root exudates for microorganism
It can promote a variety of and nitrogen, phosphorus metabolism related microorganisms growth；(5) Radial Oxygen Loss from Root effect can strengthen nitrification and organic matter
Aerobic degradation.(4) porousness for improving ecological bed fillers, maintains the waterpower transmission stability of bed.
To the detergent power of pollutant, there are significant differences in different physiological stages for plant, therefore select the reasonable time pair
Wetland plant, which is gathered in and managed, can maintain composite ecological bed higher wastewater purification efficiency.The present invention provides a kind of easy
It is composite ecological bed in the tube bank type water purification of plant regulatory and recycling, it solves plant dry branches and fallen leaves in artificial ecology bed and is difficult to
The problem that effectively recycling is removed and the water plant of well developed root system is difficult to low cost harvesting and recycles, by ecology
Kind, which is implanted with the plant of economic value, in bed can realize environment and economic double benefit.
