Description
[technical field]
The present invention relates to sewage disposal system, particularly relate to a kind of biological deodorizing filler.
[background technology]
The processes such as many commercial production, sewage, process and refuse disposal all can produce substantial amounts of foul gas.Ecological environment is not only caused and has a strong impact on by foul gas, and health has great harm, nervus centralis can be made to produce obstacle, pathological changes, cause chronic disease, acute disease.Pumping plant foul smell in municipal sewage plant, pretreatment foul smell, Treatment of Sludge foul smell are required for taking measures to collect eliminating.Therefore, the correlational study to odor treatment method is to environment or for the mankind to be all very important problem.
At present, odor treatment method is a lot, has Physical, chemical method and bioanalysis etc..Wherein, biological treatment because of with low cost, non-secondary pollution, be easily managed, safe and reliable and receive much concern.Biological deodorizing is the biological exhaust gas treatment technology adopting bioanalysis that waste odour-gas molecule is undertaken deodorization by cultivating in the biofilter microbial film on biologic packing material specially, and biomembrane one side, with the pollutant in waste gas for nutriment, carries out growth and breeding；On the other hand by poisonous, the harmful rotten substance decomposition in waste gas, it is degraded into simple inorganic matter such as nontoxic CO2, H2O, H2SO4, HNO3 etc., thus reaching the purpose of deodorization.Microbial growth, as biomembranous growth basis, is played vital effect, directly affects deodorizing effect by biologic packing material.Therefore, improvement and development to the filler (i.e. microbe carrier) in odor removal have important practical significance.
[summary of the invention]
The present invention overcomes defect and the deficiency of microbe carrier in existing odor removal, it is provided that a kind of existing resource realizes effectively recycling, economic and environment-friendly biological deodorizing filler.
In order to realize foregoing invention purpose, the technical solution used in the present invention is:
A kind of biological deodorizing filler, this filler is by following composition by weight: circular volcanic rock haydite, cocoanut active charcoal granule, Aerobic Pond activated sludge pelletize, bark, Folium Pini, leaves form than pelletize after Homogeneous phase mixing with the quality of 4: 2: 1.5: 1: 1: 0.5；This filler is packed density is 0.65～1.1g/cm3, specific surface area be 250～400m2/ g and the circular granular thing that diameter is 0.9～6.3cm.
Preferably, the diameter of described circular volcanic rock haydite is 3～6cm.
Preferably, the diameter of described cocoanut active charcoal granule is 2～3cm.
Preferably, the diameter of described Aerobic Pond activated sludge pelletize, bark, Folium Pini and leaves is 1～2cm.
The invention has the beneficial effects as follows:
The present invention takes into account resource reutilization, the biologic packing material that a kind of nutrition-allocated proportion is good, cost performance is high is provided, this biologic packing material is made up of by after the composition mix homogeneously of certain part by weight the circular volcanic rock haydite of diameter 3～6cm, the cocoanut active charcoal granule of diameter 2～3cm, the Aerobic Pond activated sludge pelletize of diameter 1～2cm, bark, Folium Pini, leaves, construct filler basis due to haydite and activated carbon granule and can increase support strength, there is the huge absorption surface can for biofilm development, form space, increase biomembrane and amass with foul smell solution contact surface；And Aerobic Pond activated sludge has abundant nutrition, for microbiologically stabilised growth；Folium Pini, bark, leaves be last decomposition under microbial action, and slow releasing is organic, supplies biofilm development.
This biologic packing material composition is simple, utilizes the original mud of Sewage Plant, gardens waste material, had both met the nutrition needed for biological deodorizing and medium basis, and had reached again resource reutilization, economic and environment-friendly effect.Effectively reach the recycling of Sewage Plant Aerobic Pond activated sludge and gardens waste material resource.
