Hebei factory direct water treatment packing packing tape identified national patent products

Braided belt braided belt water treatment packing filler is a national patent products, first in the country, processing technology has reached domestic leading level, product environmental performance to the domestic advanced level, leading technology products. The filler is a new generation of environmentally friendly bio-active filler, woven from special material, special technology, the world's leading equipment made hydrophilic, lipophilic, the bubble has a good cutting action, there is an oxygen storage function, strong adsorption capacity. At the same time due to the impulse by water and air flow, the biofilm on the packing constantly updated, biologically active, high mass transfer efficiency. Mimic natural plants form, easily satisfied Tibetan sludge, when oxygenated tube has a diameter variability, non-blocking, etc., long life, and therefore, the filler than other fillers can improve the water efficiency of 70-80%. By varying the size of the filler structure are suitable for different environments (aerobic, anaerobic and facultative), generally processed into a curtain-type structure, easy to install, it is also known as water curtain braided packing, microorganisms can fully play their performance. The product is mainly suitable for urban wastewater, sewage and industrial wastewater treatment (wool spinning, dyeing, leather, paper, pharmaceutical, food and other industries) and pollution of rivers and lakes of water purification. The product is eligible in the 2001 national utility model patents, and won the China Patent Technology Exposition gold medal, the same year as a national Torch Program, 2002 as the state's key environmental protection practical new technology. The successful development of filler since 1997, worked in dozens of manufacturers widely used. This filler has a biofilm fast, good biofilm development, with rich biological communities, constitute a long food chain of bacteria, algae, protozoa, metazoan, etc. contained in sewage and other organic matter and nutrients through the food chain and biofilm many contacts, migrate and conversion, degradation become the final product CO2, H2O, NH3-N, NOx-N, PO4, etc., they are also through nitrification, denitrification, assimilation process is removed, so as to achieve a high purification efficiency; Meanwhile, the long food chain biofilm efficiently consume bacteria, algae, protozoa, metazoan leaving generate substantial reduction in the biomass, resulting in very little excess sludge, activated sludge process is only 1/20, may 1-2 months once discharged sludge, and few in number, and onsite and use can be. The filler also with acid, good mass transfer and so on. It also has a light weight, low investment, low operating costs, long life, easy installation and maintenance, and other equipment is easy to use features. Therefore, the filler has a high economic and social benefits. This braided packing curtain biofilm carrier has two categories: one for Biofilm Process tank urban sewage and industrial wastewater treatment plants, the station (or biological contact oxidation pond), and such fillers is usually down two end all be fixed suspension, forming rows of curtains, sewage flow process in the pool, by stirring and mixing aeration system, so that one of contaminants on the growth of the biofilm curtain adequate contact and biodegradable and assimilation. The second category is designed for packing contaminated rivers, ponds, lakes imitation curtain braided packing plants, the bottom end is fixed in the riverbed or pond, lake, upper wandering in a free state. When the water is clear and transparent after purification, these fillers attached to the surface because of its growing algae and green, and drift around like weeds. Therefore, this filler called imitation curtain braided packing plants. Features braided belt water packing has: ★ large surface area, high porosity, start biofilm fast, easy stripping update; ★ can effectively cut the bubbles, increase oxygen transfer rate and efficiency; ★ mimic natural plants shape, easy Tibetan satisfied sludge, long life, high resistance to shock loading, water effects good stability. The filler is eligible for patent technology Chinese utility model patents, and won the gold medal patented technology exposition, Henan Province outstanding product award, included in the state's key environmental protection practical technology (A class) to promote the project, the State Torch Program projects.
