Since the specific surface area of this kind of filler is high, the adhesion amount of microorganism is big in unit volume.
Further, the special ecological filler is that the porosity of ecological filler can reach 50%.
Further, the biofilter material is formed by three layers, is from top to bottom followed successively by thick melon seeds lamella, object filter material layer of improving people's living condition
With thick melon seeds lamella.
New type purification slot sewage disposal basic principle is that sanitary sewage first passes around hydrolysis acidification aerobic tank and hydrolysis acidification
Anaerobic pond by being attached to the effect of anaerobe on composite filling, makes dirty Organic substance in water that hydrolysis acidification occur, by sewage
Middle macromolecule organic is decomposed into small molecule, removes the organic matter in sewage, reduces the biological load of subsequent biological treatment and carry
Its high biochemical, through hydrolysis acidification anaerobic pond, treated after sewage enters water quality and quantity regulating reservoir, and sequence batch is into new bio
Filter tank.
Special ecological filler is equipped in new bio filter tank, sanitary sewage uniformly moves in packing layer, pollutant quilt
Microorganism retention, absorption in filler are adsorbed, and is converted eventually by microorganism decomposition, achievees the purpose that sewage purification.
New bio filter tank can be divided into the removal of pollutant：Removal to organic matter and the removal to nitrogen, phosphorus etc..
The removal of organic matter is mainly by the special ecological filling adsorption in new bio filter tank and special ecological filler surface attachment
Microorganism, the organic matter of resolvability are degraded by the absorption of biomembrane and the metabolic process of microorganism.
New bio filter tank intakes to be intermittent, regulating reservoir water outlet using automatic batching time water outlet, biofilter fall do with
The operational mode supplied oxygen during water inlet by snorkel, makes the biomembrane of filter material surface be in amphimicrobian and aerobic alternate ring
Border, since filter material layer and biofilm surface are negatively charged, the ammonia nitrogen in sewage is adsorbed first by filtrate, it is subsequent fall dry period
By the metabolism shift of nitrifier into NO3-, in next cycling, form NO3- and be eluted into sewage, and utilize
Organic carbon and aging biomembrane in sewage carry out denitrification and form N2, while the adsorption potential of ammonia nitrogen is released, with
Ammonia nitrogen in Adsorption sewage, meanwhile, denitrifying bacterium utilizes residual organic matter, endogenous and external source SOLID ORGANIC carbon in sewage
Source and root system of plant metabolin carry out denitrification, while further denitrogenation, remove residual organic matter.
Phosphorus in sewage mainly acts on removal by the absorption-deposition of filter material surface, in homogeneous sewage, due to metal from
The concentration of son is very low, and the solubility of phosphate radical is higher.But in water-filtrate near interface, metal ion and phosphate radical quilt simultaneously
Absorption makes the activity product of metal phosphate raise the 2-4 order of magnitude, so as to cause the phosphatic formation of insoluble metal, reach from
The purpose of dephosphorization in sewage, in order to prevent because phosphorus precipitation causes system jams, which adds in filtrate and filler can
While the activity chemistry component, i.e. calcium phosphate precipitation substituted by phosphate, there are appropriate filtrate and filler component to be dissolved, to protect
The volume for holding filtrate and filler is basically unchanged, in addition, the porosity of the technology ecology filler can reach 50%, permeability is high,
For sanitary sewage, as to phosphorus dephosphorization, porosity is gradually reducing, and eventually drops to 30%, it can accommodate 30 years or more
Calcium phosphate precipitation object.
The new bio filter tank has heavy metal the removal effect of stronger chemical precipitation, displacement and biological adsorption, right
The biological contaminations index such as bacterium, coliform, fecal coliform has stronger Physical entrapment and biochemical and biocidal to act on.
Above some exemplary embodiments that the present invention is only described by way of explanation, undoubtedly, for ability
The those of ordinary skill in domain, without departing from the spirit and scope of the present invention, can be with a variety of modes to institute
The embodiment of description is modified.Therefore, above-mentioned attached drawing and description are regarded as illustrative in nature, and should not be construed as to the present invention
The limitation of claims.
