Biological contact oxidation method is attached to the carrier (commonly known as filler) on the biofilm-based, purification of organic wastewater a highly efficient treatment process. Has been widely used in textile printing and dyeing, wool knitting, beer food, petrochemical fertilizer, medical and domestic sewage treatment, and access to significant environmental benefits, social and economic benefits. In recent years, with the increase in water demand, coupled with river water, lake water and other surface water to varying degrees by a large area of ​​organic pollution, the use of contact oxidation process for processing. Over the years, the process due to a highly efficient energy-saving, small footprint, impact load, easy operation and management of the unique advantages of the design department is widely used by the user's welcome and favor.

Biofilm carrier ... Filler is the core of the contact oxidation process, which directly affects the treatment effect, oxygenation performance, infrastructure investment, operating cycle and cost. Our production of three-dimensional elastic filler and mixed three-dimensional elastic filler is our factory by a variety of conditions and a large number of tests and long-term production results show that the ideal carrier filler. Because of the unique structure of the filler and excellent material process selection, it has a long service life, good oxygenation performance, low power consumption, fast start-up film, easy to remove the film, high load impact, the treatment effect is remarkable, Easy management, no clogging, no knot and low price and so on. The filler in the application of different water conditions, can adjust the thickness of the wire and the different forms of assembly, fully applicable to all kinds of wastewater anaerobic, aerobic, aerobic and other treatment process. The filler is the first domestic and international, its structure, performance with the international advanced level.

The filler screening of polyolefins and polyamides in several anti-corrosion, temperature, aging resistance of high-quality varieties, mixed with hydrophilic, adsorption, anti-thermal oxygen and other additives, using a special drawing, , The silk thread interspersed in the corrosion-resistant, high-strength center rope, as the selection of materials and sophisticated formula, rigid and soft, so that the three-dimensional uniform arrangement of the radiation state, made of suspended three-dimensional elastic packing monomer, Filling in the effective area can be a full three-dimensional stretch evenly stretch, so that gas, water, biofilm to be fully infiltration contact exchange, biofilm can not only evenly implanted in each wire, to maintain good activity and space Variability, but also in the course of running more and more large surface area, but also a good metabolism, this feature and the phenomenon is the current domestic filler is incomparable.

Compared with the semi-soft filler, the surface area is large and the film is fast, and the material is long, Low cost. Therefore, the filler can be confirmed as a variety of rigid filler, soft filler and semi-soft filler after the fourth generation of energy efficient novel filler.
