-------为什么选择河南东万源的火山岩滤料-------

1、外观形状：无尖粒状，对水流阻力小，不易堵塞，布水布气均匀;表面粗糙，挂膜速度快，反冲洗时微生物膜不易脱落。
2、多孔性：火山岩是蜂窝多孔，是菌胶团好佳的生长环境。
3、机械强度：经国家质检部门为5.08Mpa，实践证明可以耐得住不同强度的水力剪切作用，使用寿命远远长了其它滤料。
4、密度：密度适中，反冲洗时容易悬浮且不跑料，可以节能降耗。

-------火山岩滤料简介-------

     火山岩生物滤料经过选矿、破碎、筛分、研磨等一系列工艺加工而成的粒状滤料，其主要成份为硅、铝、钙、钠、镁、钛、锰、铁、镍、钴和钼等几十种矿物质和微量元素，表观为不规则颗粒，颜色为红黑褐色，多孔质轻，颗粒粒径可根据不同要求生产。

-------物理结构特点-------

     火山岩生物滤料在物理微观结构方面表现为：表面粗糙多微孔，这些特点特别适合于微生物在其表面生长、繁殖，形成生物膜。火山岩滤料使曝气生物滤池不仅能处理市政污水，以及可生化的工业废水、生活排水、微污染水源水等，也可在给水处理中取代石英砂、无烟煤等用作过滤介质，同时还可对已经过污水处理厂二级处理工艺后的尾水做处理，其处理出水达回用水标准后可作中水回用。

-------化学结构特点-------

     火山岩生物滤料在化学微观结构方面表现为：1、微生物化学稳定性：火山岩生物滤料抗腐蚀，具有惰性，在环境中不参与生物膜的生物化学反应。 2、表面电性与亲水性：火山岩生物滤料表面带有正电荷，有利于微生物固着生长，亲水性强，附着的生物膜量多且速度快。 3、对生物膜的影响方面：作为生物膜载体，火山岩生物滤料对所固定的微生物无害，实践证明不影响微生物。

-------水力学方面特点-------

1、空隙率：内外平均孔隙率在40左右，对水的阻力小，同时与滤料相比，所需滤料量少，同样能达到预期过滤目标。
2、比表面积：比表面积大、开孔率高且惰性，有利于微生物的接触挂膜和生长，保持较多的微生物量，有利于微生物代谢过程中所需的氧气与营养物质及代谢产生的废物的传质过程。
3、滤料形状与水的流态：由于火山岩生物滤料是无尖粒状，且孔径大多数比陶粒要大，所以在使用时对水流的阻力小，节省能耗。

-------英文简介-------

[volcanic rock introduction]

Volcanic filter after separation, crushing, screening, grinding and a series of processing technology of granular media. Its main components for silicon, aluminum, manganese, iron dozens of minerals and trace elements, performance is close to the circular particles, color is red brown, porous light and particle size can according to the different requirements of production.
[volcanic rock biological filter material performance characteristics]
1 appearance shape: no sharp granular, little resistance to the water, not easy to plug, cloth water evenly; rough surface, hanging film speed, anti flush when the microbial film is not easy to fall off.
2 porous: volcanic rock is a natural honeycomb porous, is the best growth environment.
3. Mechanical strength: by the national quality inspection departments 7.08Mpa and practice that can withstand hydraulic shear of different strength, service life is much longer than other media.
4 density: the density is moderate, the back flushing is easy to suspend and does not run the material, may save energy and reduce consumption.
5 biological chemical stability: volcanic rock biological filter material corrosion resistance, with inert, in the environment does not participate in the biological chemical reaction of biological membrane.
6. Surface and hydrophilic: volcanic biological filter material surface with positive charge, is conducive to the growth of microorganism immobilization, strong hydrophilicity, attached biofilm quantity and speed.
7 on the impact of biological membrane activity: as a biological membrane carrier, volcanic rock biological material on the fixed micro-organisms harmless, non inhibitory effect, practice does not affect the activity of microorganisms.
[volcanic rock biological filter material hydraulic characteristics]
1, void ratio: inside and outside the average porosity of about 80%, the resistance to water is small, at the same time, compared with the same kind of filter material, the required filter material quantity is little, also can achieve the anticipated filtration goal.
2, specific surface area: large specific surface area, high porosity and the inertia, is advantageous in the microbial exposure hangs the membrane and the growth, maintain more microbial biomass, is conducive to the mass transfer process of microbial metabolism in the process of oxygen and nutrients and metabolic waste.
3, the shape of the filter material and water flow pattern: the volcanic rock biological filter material is no sharp granular, and most of the pore size than the ceramic, so the resistance to water is small, saving energy.
[volcanic rock use]
Volcano stone (commonly known as porous pumice or Xuan Wuyan) is a type of environmentally friendly materials, porous stone shaped by volcano glass, minerals and bubble formation is very precious volcano, volcano stone contains sodium, magnesium, aluminum, silicon, calcium, titanium, manganese, iron, nickel, cobalt and molybdenum and other dozens of kinds of minerals and trace elements, use the volcano rock in BAF can not only deal with the municipal sewage, water environmental water, biochemical organic industrial wastewater, miscellaneous drainage, micro polluted water, oil filter and so on, also can be in the water treatment Nakatori Yoshihidesa, activated carbon, anthracite used as filter medium, and may also have been the plant two treatment process after the tail water of sewage treatment, the effluent water reuse standards for water reuse, volcano rock to filter the material to its quality is low, the filtering effect. Field prices, applied in water treatment in all aspects, has been more recognized and supported by the industry.
