Bubble structure is fine volcanic eruption thermal expansion and contraction in the natural formation of volcanic rock is processed by selected media processing, bio-activation processes become, especially in the industrial production of environmentally friendly water industry has a broad effect. Volcanic filter through beneficiation, crushing, screening, grinding process with a series of granular media, the main component of silicon, aluminum, manganese, iron and other dozens of minerals and trace elements, the performance of nearly round particles , the color is red, black and brown, porous light weight, particle size can be produced according to different requirements. Efficient performance of hanging light filter film surface roughness microporous microstructure in the physical structure, particularly suitable for these features on the surface of microbial growth, reproduction, the formation of biofilms. Volcanic filter in terms of not only BAF treatment of municipal sewage and industrial wastewater biodegradability of organic micro-polluted water, etc., can also be replaced by quartz sand to water treatment, activated carbon, anthracite as filter media, while also may have been on the tail water sewage treatment plant secondary treatment process to do the depth of the treatment, the treated effluent water back up to the standard can be used for water reuse. First, volcanic media - the physical characteristics of an Appearance: no sharp granular, on the flow resistance is small, easy to plug, water distribution uniform gas distribution; surface roughness, biofilm fast, microbial membrane backwash easy to fall off. 2 porous: natural honeycomb porous volcanic rock, is zoogloea optimal growth environment. 3 Mechanical strength: the State quality inspection departments to 5.08Mpa, proved can withstand different hydraulic shear strength, life is much longer other media. 4 Density: medium density, and not easy to run backwash suspended material can save energy. Second, volcanic filter - a biochemical stability and chemical properties: Volcanic biological filter corrosion, inert, does not participate in the biofilm environment of biochemical reactions. 2 electrical and hydrophilic surfaces: Volcanic biological filter surface with a positive charge, is conducive to the growth of microbial fixation, hydrophilic, and more attached biofilm volume and speed. 3 impact on biofilm activity: as a biofilm carrier, volcanic biological filter for the fixed microorganisms harmless, no inhibitory effect, proved not affect microbial activity. Third, volcanic filter - a hydraulic characteristics, porosity: internal and external average porosity of about 40%, small water resistance, while compared with the same filter, the filter needed less, the same can achieve the desired filter goals. 2, specific surface area: a large surface area, high porosity and inert beneficial microbial biofilm formation and growth of contact, keeping more of the microbial biomass, microbial metabolic processes in favor of the necessary oxygen and nutrients and metabolites produced. waste mass transfer process. 3, the filter shape and water flow patterns: Since no sharp volcanic biological filter is granular and ceramic aperture larger than most, so when using a small resistance to fluid flow and save energy. Fourth, volcanic filter - Use Volcanic biological filter is mainly used in the BAF, not only used in municipal wastewater treatment, biological treatment of organic industrial wastewater, domestic wastewater treatment, especially for wastewater, waste gas, food processing Park industrial waste, waste oil, wastewater, wastewater biological treatment slaughter plants have a good effect; another volcanic biological filter material is the key to achieve BAF sewage treatment process, the product with the traditional bio-ceramic phase ratio, not only has the light texture, good chemical stability, strength suitable film surface roughness easy to hang the advantages and developed porosity distribution reasonable, very suitable for microbial inoculation, domesticated, growth and reproduction. Wash-resistant, non-blocking, good physical, chemical and hydraulic characteristics, can be adapted to different requirements for water purification. Since the ceramic surface area, can accumulate high concentrations of microbial biomass, high concentrations of microorganisms make BAF volume load increases, the removal rate is high. Unit volume of sewage treatment 5-7 times more efficient than conventional media, to meet environmental emissions standards. This product has been "water filter Ministry of Construction Quality Supervision and Inspection Center" test, indicators of quality and reliable performance.
