上海生物挂膜火山岩滤料 有机生物过滤火山岩滤料

火山岩滤料介绍

      火山岩经原矿石精选加工处理，生物活化等工序加工而成，表观为不规则空隙及颗粒，颜色为黑褐色。多孔质轻，颗粒的粒径可根据不同的要求进行生产。火山岩生物滤料用在中水回用和污水处理的曝气生物滤池已经有几年的历史。根据多年使用经验，在国内寻找到满足污水处理使用的火山岩滤料的原料。火山岩滤料可生化处理有机工业废水、市政污水，生活杂排水、微污染水源水等。

      由于该火山岩滤料比表面积大，可积累高浓度的微生物量，高浓度的微生物使曝气生物滤池的容积负荷增大，去除率高。单位体积污水处理效率比常规滤料提高5-7倍，可以满足环保排放标准。

Volcanic rocks in the original ore processing, biological activation process and apparent for irregular pores and particles, the color is dark brown. Porous light, particle size can be ordered according to the different production. Volcanic rocks in the biological filter material used in water reuse and wastewater treatment aeration biological filter has a history of several years. According to use the experience for many years, seek to meet the sewage treatment in domestic use of volcanic rocks in the filter material of raw materials. Volcanic rocks in the filter material can be organic industrial wastewater biochemical treatment, municipal sewage, life drain, and slightly polluted source water.

Due to the volcanic rocks in the filter material is greater than surface area, can accumulate a high concentration of microbial quantity, high concentration of microorganisms increased aeration biological filter volume load, high removal rate. Unit volume efficiency of sewage treatment 5 to 7 times higher than that of conventional filter material, can meet the environmental emission standards

火山岩滤料特性

      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：火山岩是天然蜂窝多孔，是菌胶团较佳的生长环境。

      3.机械强度高。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。

1. Appearance shape: no pointed granular, on small flow resistance, not easy jam, cloth water gas evenly; Rough surface, hang film speed, backwash when microbial membrane is not easy to fall off.

2. The porous: volcanic rock is a natural honeycomb porous, is the growth of zoogloea best environment.

3. High mechanical strength. Practice prove that can withstand the intensity of different hydraulic shearing action, service life is much longer other filter material.

4. The density: medium density, backwash easily suspended and not run, can saving energy and reducing consumption.

火山岩滤料用途

      火山岩生物滤料是实现曝气生物滤池污水处理工艺的关键材料，火山岩生物滤料与传统的生物陶粒相比，不仅具有质地轻、化学稳定性好、强度适宜、表面粗糙易挂膜等优点，而且孔隙发达，分布合理，非常适合微生物的接种、驯化、繁殖生长。耐冲洗、不堵塞，具有良好的物理、化学和水力特性,可适应于不同污水净化的要求。

      火山岩滤料使用在曝气生物滤池不仅能处理市政污水，以及可生化的有机工业废水、生活杂排水、微污染水源水等，也可在给水处理中取代陶粒、石英砂、活性炭、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深度处理，其处理出水达回用水标准后可作中水回用。

Volcanic rocks in the biological filter material is to realize the aeration biological filter sewage treatment technology of the key materials, volcanic rocks in the biological filter material compared with the traditional biological ceramsite, not only has a light texture, good chemical stability, intensity the advantage such as suitable for rough surface, easy to hang the membrane, and pore developed, reasonable distribution, very suitable for the inoculation, domestication and breeding of microorganism growth. Resistance to flush, non-clogging, has the good physical, chemical and hydraulic characteristics, can be adapted to the requirements of different sewage purification.

Volcanic rocks in the filter material used in the aeration biological filter can not only deal with municipal wastewater, and a biochemical organic industrial wastewater, complex drainage, slightly polluted source water of life, etc., can also be used in water treatment to replace ceramsite, quartz sand, activated carbon, anthracite and other used as filter medium, at the same time also can have after sewage treatment plant secondary treatment process of tail water do deep processing, after the recycle water for water standard for water reuse.
