Abstract
The invention discloses a kind of sewage treatment film bed, including bed ontology, the bed ontology is molded by PVC material and culture machine body heat, and the culture body includes the crushed material of the forest and agricultural biomass containing lignin fibre and carbon fibre.Present invention process is simple, biomembrane is full of nutrition, and the biofacies on film is abundant, and the biological flora adhered on film is not easily to fall off, high to the purification efficiency of sewage, and effect is good.
Description
Technical field
The present invention relates to sewage treatment film beds.
Background technique
Traditional biological film production is using polymer plastic as carrier, in water phase, attached collection culture is carried out, to look unfamiliar in plastic table
Long microbial flora, its advantage is that it is durable, but disadvantage leads to tradition it is also obvious that i.e. since polymer plastic lacks nutrition
Biofacies on biomembrane is relatively simple, and when machinery trembles, and when such as aeration, the biological flora adhered on film is easily de-
It falls, affects the biomass in unit volume in this way, there is very big adverse effect to the catharsis of biofilm bed.
Summary of the invention
The technical problem to be solved by the present invention is to existing biomembrane lacks nutrition, and the biofacies on film is relatively simple, film
The biological flora of upper attachment is easy to fall off, not high to the purification efficiency of sewage, and effect is poor.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: sewage treatment film bed, including bed ontology, institute
State an ontology by PVC material and culture machine body heat it is molded, it is described culture body include forest and agricultural biomass crushed material.It uses
Forest and agricultural biomass can effectively turn waste into wealth, and economize on resources, and use material and PVC containing lignin fibre and carbon fibre
Material combines production biomembrane, and it is scarce as the single phase property of biomembrane and without trophism and flora unification to change pure plastics
It falls into, strengthens the activity of biologic packing material, so that the microbial flora that film adheres to above is more abundant, for the processing of various water quality
With broad spreadability.
Further, the forest and agricultural biomass is using at least one of rice husk, straw and reed.Rice husk, straw, reed are all
It is existing more rural surplus object, the mode that whens these residues of conventional process generallys use burning carries out, by ashes
It inserts and is used as fertilizer in soil, such case seriously pollutes atmosphere, and when rural collective burns, entire village is all full of smoke,
By the present invention in that making film bed with these substances, not only turns waste into wealth, the substance of script rubbish is allowed to create economic valence
Value also plays great propulsion to protection environment, has not only prevented air pollution, and product can also improve water quality, protects water
Resource.Since the effect of rice husk, straw, reed is all identical, when production, rice husk in forest and agricultural biomass, straw and
The component of reed arbitrarily matches, and can regard rice husk, straw and the stock number of reed and determine, measure it is more add, measure it is few few plus, or
Person is depending on rice husk, straw and the purchasing price of reed, and cheaply are put more, and not cheap lacking is put.
Further, the culture body further includes the crushed material of organic matter object, the weight of organic matter object and forest and agricultural biomass
Than for 1:19-22, and uniformly mix.Industrial wastewater to be processed at present is all generally poor nutrition waste water, due to lacking organic matter,
The advanced treating of sewage is not can guarantee.The present invention increases organic matter in film bed, is capable of the phosphorus content of adjusting film bed, enhances water body
In bioactivity and nutrient source, to ensure that the effect of the advanced treating of sewage.
Further, the organic matter object uses at least one of poultry manure and the dregs of fat.Both things are common
Rural area produce rubbish, be deposited in it is very serious to the pollution of environment in village, although can give soil top dressing, in this process
In, these pollution sources are fabricated directly into biofilm bed by mosquito fly easy to breed, and not only extra earning, has also prevented pollution sources, changes
It has been apt to rural environment.Since the effect of poultry manure and the dregs of fat is all identical, when production, poultry manure and the dregs of fat
Component arbitrarily match, the stock number that can regard poultry manure and the dregs of fat is determined, measure it is more add, measure it is few few plus, or view
Depending on the purchasing price of poultry manure and the dregs of fat, cheaply are put more, and not cheap lacking is put.
Further, the PVC material be PVC biomembrane, culture body uniformly adhere to PVC biomembrane a side surface or
Both side surface forms the bed body of plate by hot pressing.It is simple that this mode makes film bed process, easy to operate, will cultivate body
It is uniformly filled with the surface of film, hot pressing is integral, adheres to culture body by biomembrane, so that molding biomembrane is more suitable bacterium
Group's grown cultures, and can not fear the impact of flowing water during handling sewage, firmly be attached on film.
Further, the PVC material is PVC granule, and culture body is uniformly mixed with PVC granule, forms plate by hot pressing
Shape is netted or block-like bed body, cultivates the weight ratio 1:3-10 of body and PVC material.It is mixed by PVC granule and culture body
It closes, in hot pressing, plastics to cultivate body by high temperature melt and plastics combine together, convenient for making the shape of various needs
Biomembrane, be suitble to the needs of various water treatments.
The invention has the advantages that simple process, biomembrane are full of nutrition, the biofacies on film is abundant, the life adhered on film
Object flora is not easily to fall off, high to the purification efficiency of sewage, and effect is good.
Specific embodiment
Embodiment 1
For the sheet biofilm bed of nutrition wastewater treatment.
Film bed of the invention is PVC material and the molded bed body of culture machine body heat, and the culture body is used containing wooden
The crushed material of the forest and agricultural biomass of quality fiber and carbon fibre, the forest and agricultural biomass use rice husk.The PVC material is
PVC biomembrane, the weight ratio for cultivating body and PVC material is 1:4；Culture body uniformly adheres to a side surface of PVC biomembrane
Perhaps both side surface is reticulated or the bed body of plate by hot pressing.It is simple that this mode makes film bed process, is easy behaviour
To make, culture body is uniformly filled with to the surface of plastic biofilm, hot pressing is integral, culture body is adhered to by biomembrane, so that
Molding biomembrane is more suitable flora growth culture, and can not fear the impact of flowing water during handling sewage, firmly attached
