(2), the theoretical diameter of the single chamber between external toroidal ring and the interior ring is 0.5mm, blade diameter length ratio is 0.5, the space structure design of chamber is reasonable, is beneficial to microbial film and the mass transfer between water body and biography oxygen in the chamber, and the vital movements such as the new one-tenth metabolism of microorganism, growth and breeding are vigorous.
(3), the specific surface area of single filler is about 1100m
2/ m
3, the effective ratio area after the accumulation is about 470m
2/ m
3, effective ratio area is large, and the microorganism colonization amount of unit volume filler is large.
(4), add a certain proportion of hydrophilizing agent in the making processes, filling surface is hydrophilic, drops into the initial stage of biochemical aeration tank at filler, microorganism colonization speed is fast, greatly shortens the engineering debug cycle.
(5), add a certain proportion of antioxidant in the making processes, the performances such as anti-aging, the antiultraviolet of filler improve greatly, prolong work-ing life, this use can reach more than 15 years novel work-ing life.
