Filler is widely used as an essential carrier for microbial film in biochemical system. The elastic filler reduces the comprehensive treatment cost of electricity and water, and has good economic benefits. The combined process effluent is also better than tap water. For water shortages, the company’s invention is strictly controlled under total control, which has a very broad application prospect and prospects Outlook.
The characteristics of the elastic filler film:
Elastic fillers are widely used as biological fillers in biological contact oxidation tanks and hydrolytic acidification tanks. It has a good treatment effect on low-concentration domestic sewage, medium-concentration printing and dyeing wastewater, papermaking wastewater, oily wastewater, high-concentration food industry wastewater, and chemical wastewater.
The elastic filler is made of corrosion-resistant, high-temperature-resistant, aging-resistant polyalkenyl hydrogen and polyamide, and a mixed copolymer of hydrophilic, adsorption, and anti-heat itch additives as the material. It adopts special wire drawing and silk wool making process. The thread is inserted and fixed on the corrosion-resistant, high-strength central rope. There are four specifications of elastic packing: Φ150mm, Φ160mm, Φ180mm, Φ200mm.
Due to the special technology used in the drawing process of the elastic filler, the surface of the elastic thread is drawn into corrugations and burrs, thereby increasing its specific surface area and the performance that is beneficial to the adhesion of microorganisms. The thread strips are arranged in a spiral and radial shape with the central rope as the axis. Fully stretched in the water, so the three-dimensional distribution is uniform. The elastic thread with a certain rigidity can perform multi-level collision cutting on oxygenated bubbles to improve the oxygen transfer rate and oxygenation power efficiency. At the same time, the thread is affected by the impact of air and water, causing slight vibrations and induce turbulence, increasing The contact with water, air, and microorganisms improves the mass transfer effect and promotes the metabolism of microorganisms, thereby enhancing the efficiency of wastewater treatment. It has a long service life, good oxygenation performance, low power consumption, fast start-up and film release. It is easier, resistant to high load impact, has obvious treatment effect, simple operation and management, no clogging, no clumping, etc.
From the above, it can be concluded that the elastic filler mainly hangs up the membrane for domestic sewage, improves the transfer rate of oxygen and the efficiency of oxygenation power, intercepts microorganisms to add sludge age, and facilitates the effect of full touch response of sewage sludge.
