Description
Technical field
The present invention relates to water-treatment technology field, more particularly to a kind of artificial swamp immobilization functional stuffing.Build and
Into a unique sewage disposal synthesis ecosystem being made up of substrate, plant, microorganism and water body.It is a kind of collection thing
Reason, chemistry, biochemical reaction in the wastewater processing technology of one, by filtration, absorption, coprecipitated, ion exchange, chemical degradation, plant
The high-efficient purification to sewage is realized in the effect such as thing absorption and microorganism decomposition.
Background technology
Artificial swamp presses water stream characteristics, can be divided into surface flow artificial marshland, drowned flow artificial wet land, vertical current constructed wetland three
Kind.Surface flow artificial marshland expenditure of construction is relatively saved, but floor space is easily tied more than undercurrent and vertical current constructed wetland, and winter surface
Ice, summer easily breeds mosquito, and has stink.The advantage of drowned flow artificial wet land is the space that it makes full use of wetland, plays system
Synergism between system, and sanitary condition is good, but construction cost is high compared with surface flow artificial marshland.Vertically latent artificial swamp has more preferable
Nitrogen/Phosphorus Removal, take up an area little, oxygen supply is good, but relative other artificial swamps height of construction cost.Drowned flow artificial wet land is to COD's
In 80-90, to the clearance of total nitrogen in 40-50, the place to go rate of total phosphorus is in 40-60 for clearance.With respect to other sewage disposal systems,
Artificial swamp small investment, operating cost is low, and without the need for personal management, treatment effect climate affects little, and sanitary condition is good, nothing
Stench, wetland surface can plant ornamental plant, beautify the environment.
Artificial swamp is the artificial ecological system for simulating natural wetland, is similar to Sanjiang Plain ground, but by manually building and supervise
Control is superintended and directed, is that artificially one or more media constitute according to a certain percentage substrate to one kind by stone, sand, soil, cinder etc., and had
Optionally it is implanted into plant, the built-up one unique sewage disposal being made up of substrate, plant, microorganism and water body is comprehensive
Close ecosystem.It is a kind of wastewater processing technology for integrating physics, chemistry, biochemical reaction, by filtering, adsorbing, altogether
The high-efficient purification to sewage is realized in the effect such as heavy, ion exchange, chemical degradation, plant absorption and microorganism decomposition.
Artificial swamp be by substrate, water body, plant, animal and microorganism group into ecosystem.In living in soil
Microorganism (antibacterial and funguses) plays a major role in a good appetite suddenly appearing in a serious disease that goes of Organic substance, and the root system of wetland plant is brought into the soil of surrounding by oxygen
Earth, but the environment away from root is in anaerobism, forms the change band of processing environment, and this just strengthens artificial swamp and removes complicated dirt
The ability of the difficult pollutant of dye thing.The removal of most of Organic substance is the microorganism leaned in soil, but some pollutant are such as
Heavy metal, sulfur, phosphorus etc. depend on the effect of soil and plant.
Constructed wetland bed base has huge surface area, specific chemical composition, countless root systems of plant and its metabolite
(oxygen, bioactive substance) is the filtration retention of pollutant, physics and chemisorbed, chemolysis and precipitation, biological uptake and
Oxidation Decomposition, mineralising etc. are there is provided good condition.
Organic substance in sewage relies primarily on the physics in constructed wetland bed base and the combined process of biology is removed.It is insoluble
Property Organic substance is filtered retention, hydrolysis, biological uptake and oxidation Decomposition, and dissolved organic matter is directly hydrolyzed, biological uptake and oxygen
Change and decompose.
Ammonia nitrogen in sewage is most of by nitrifying in bed base --- and denitrification biochemical process is removed, part ammonia nitrogen and nitre
Nitrogen is removed by plant absorption.Organic nitrogen is in mainly suspension, is filtered by bed base and is retained, and is ammonia by biochemical action mineralising
Nitrogen, nitrate nitrogen, and then by plant absorption and nitrification --- denitrification process is removed.
Phosphor in sewage mainly passes through calcium, ferrum, the aluminium ion in constructed wetland bed base mostly with the presence of orthophosphate form
Precipitation set, and the absorption process removal of plant, precipitating the phosphorus anchored in bedding finally can be changed by bed base material and be moved
Go out.
The metabolism growth process of constructed wetland plant is converted into the nitrogen absorbed from sewage, phosphorus, Organic substance, inorganic salt etc. can
The further Biomass of recycling is removed simultaneously by harvesting.
Some micro metals are removed by the absorption or co-precipitation of constructed wetland bed base in sewage, by wetland plant
Absorption, absorption are removed.
Most of pathogen and virus are ingested decomposition by the aerobic miniature organism of constructed wetland bed base in sewage, partly by plant
Root exudates is killed.
