Application

Volcanic stone is a multi-functional natural material with high economic and social value. It can be used to produce building materials, fertilizers, chemical raw materials, pharmaceutical raw materials, environmental protection products, medical supplies, home decoration and so on. Volcanic stone has the characteristics of wear-resistant, pressure-resistant, antibacterial, anti-inflammatory, etc., and has wide application prospects in various fields.

Because the volcanic stone is loose and porous and rich in minerals, it is used for plant soil or pavement, which has the effect of insulation and ventilation, increasing the soil permeability, preventing the root rot of plants, and being used as an aquarium landscape, which can cultivate nitrifying bacteria in the water and decompose harmful ammonia nitrogen.

Physical properties Appearance shape: no sharp granular, small resistance to water flow, not easy to plug, uniform distribution of water and gas, rough surface, fast film hanging speed, repeated washing microbial film is not easy to fall off.

Porosity: Volcanic rocks are natural honeycomb porosity, which is the best growth environment for bacterial micelles.

Mechanical strength: The quality inspection department is 5.08Mpa, and the practice has proved that it can withstand the hydraulic shear of different strengths, and the service life is far longer than other filter materials.

Density: moderate density, easy to suspend and do not run when backwashing, can save energy and reduce consumption.

Biochemical stability: volcanic biofilters are resistant to corrosion, inert, and do not participate in the biochemical reactions of biofilms in the environment.

Surface electricity and hydrophilicity: The surface of volcanic rock biofilter is positively charged, which is conducive to microbial fixation growth, strong hydrophilicity, and the amount of attached biofilm is large and fast.

Impact on biofilm activity: As a biofilm carrier, volcanic rock biofilter has no harmful and non-inhibitory effect on the fixed microorganisms, and practice has proved that it does not affect the activity of microorganisms.
