Description
Technical field
The utility model belongs to technical field of sewage, and in particular to a kind of combined artificial wetland of dephosphorization denitrogenation.
Background technology
At present, water environment pollution is mainly characterized by the severe overweights such as body eutrophication, especially N, P, sewage disposal
It is one of important means for preventing and treating water environment pollution.The application of artificial marsh sewage treatment system start from the early 1970s,
It is a kind of matrix, plant and the coefficient sewage disposal system of microorganism, there is small investment, operating cost is low, management is convenient
The advantages that, it is a kind of relatively conventional dirty water living creature processing technique.Artificial Wetland Techniques are artificially to add in the pond body built up
Some fillers are added to form artificial swamp bed body, when sewage flows through wetland bed body, by the filtering of wet land filler in bed body, retention etc.
Effect is made a return journey except the polluter in sewage.Although artificial swamp is in sanitary sewage disposal, pollution of waterhead control, water remediation
In be widely used, but the easy saturation of matrix, easily block, the problems such as floor space is big, also have impact on people to a certain extent
The treatment effect of work wetland, the service life of artificial swamp is shortened, hinder the popularization and application of artificial swamp.
One of key problem of Artificial Wetland Techniques is the selection of filler, and carrier performance is made to its treatment effeciency, engineering
Valency and operating cost have a great influence.Coal-fired clinker is one kind of industrial solid wastes, is thermal power plant, industry and civil pot
Stove and the waste residue of the coal-fired discharge of other equipment.Clinker and flyash belong to the accessory substance of coal dust firing, but due to formed temperature,
The influence of the factors such as deslagging technique, its form irregular, adhesion are serious, apparent entirely different and flyash.Flyash is ground
Study carefully with application technology comparative maturity, and the application of clinker still is limited to construction material, the bed course of highway and backfill etc., application
Added value is relatively low.Develop coal-fired clinker value added applications approach all has weight for environmental protection and utilization of waste as resource
The realistic meaning wanted.

Valency is low, is not easily blocked.The coal-fired clinker of first packing layer is formed by high-temperature firing, and character is stable, anticorrosive and be not involved in
The biochemical reaction of biomembrane, replacement frequency is reduced, it is cost-effective；And by broken, preferable particle size is not more than
70mm, 400 ~ 550kg/m of bulk density3, porosity 30% ~ 50% coal-fired clinker, rational bulk density and porosity are micro-
The apposition growth of biology provides carrier, and biofilm speed is fast and difficult for drop-off, and can reduce the pressure to the second packing layer, drop
The low possibility blocked.The second packing layer selection the Yellow River sand and this kind of industrial solid castoff of flyash, through ball milling, are stirred
Mix, rest, be steam-cured, cutting etc. technique obtain, phosphor-removing effect is good, with the first packing layer cooperate, efficient denitrification can be reached
The purpose of dephosphorization.
The utility model is simple in construction, easily manufactured, is not easily blocked, simple and convenient operation and maintenance；Filler is only by coal-fired clinker, river
Sand and flyash composition, composition is simple, and character is stable, and current flow in serpentine state in whole combined artificial wetland, in water
The organic matter such as nitrogen, phosphorus purification efficiency is good, and hydraulic load is big, reduces the area of artificial swamp, meanwhile, the combined artificial wetland
Service life also extended.
