BAF sewage wastewater treatment aeration biological filter

Biological aerated filters technology (hereinafter referred to as BAF) is at the end of the eighty s and early ninety s, the water treatment process, the rise in biological contact oxidation and biological activated carbon based on the technology developed a kind of high efficient and low biological reactor. The technology first used in sewage depth (level 3) treatment and reuse occasions, after can be applied to both developed into the slightly polluted water the pretreatment of the water (such as except algae, remove organic pollution), and can be directly used for urban sewage treatment field, new technology of secondary.

Features:

1. Covers an area of less for the traditional activated sludge: (1/2--1/3)

2. Low operating cost: moisture contact time long, sample transfer high efficiency; Hydraulic retention time is short, gas water than the low (2-5:1)

3. Can avoid the block:

Not for packing and broken, fiber erosion of the valve blocked;

Won't because of membrane, make pore jams growth packing taoli surface biological film thickness protection in less than 0.2 mm.

4. High biological activity: biological membrane keep higher activity; Biomass to deal with high efficiency, hydraulic retention time of 30-120 minutes.

5. Biodegradable and adsorption effect coexistence.

6. Deal with water quality: processing sewage can reach back after water (industrial or miscellaneous water) standard.

7. Operation management convenient: easy to realize automatic control, the operation is simple.
