Overview
Structure, including the cell body, fillers, water distribution system, the aeration device. The working principle is: Set in the aeration tank filler, which was used as the bio-film carrier. After
the wastewater to be treated flows through a flow rate of oxygenate to a filler in contact with the bio-film, bio-film and suspended activated sludge joint action, to effect purification of wastewater.
1. The filter requirements
(1) Large specific surface area
(2) High porosity
(3) High quality material strength
(4) Stability
(5) Reasonable price
2. The wall function
Structures of the body, play a supportive role.
3. The bottom ventilation systems, Drainage systems, supporting seepage structure
4. Water distribution system rotating water distributor
Characteristic
1.Bio-filter treatment effect is very good,It can meet the country's most stringent environmental requirements in any season.
2. No secondary pollution
3. Microorganisms able to depend on organic growth in the filler.No additional other nutrients,therefore it use fast after stopped. Weekend shutdown or lockout 1-2 weeks after the start of treatment to achieve good results immediately. A few hours later will be able to achieve the best treatment effect.Stop running 3-4 weeks before starting treatment immediately have a good effect, within a few days to restore optimal treatment effect.
4.Bio-filter has a large buffer capacity.It can automatically adjust the concentration peak microbial always work and strong ability of resistance to shock loading.
5. Run by automatic control, very stable, without manual operation. Less wearing parts, maintenance and management is very simple, which can achieve unattended. Workers inspect whether the machine simply malfunction.
6. Bio-filter using cell body assembled for easy transportation and installation. When increasing the processing capacity by simply adding components, easy to implement. Also dealt with separately under the gas source to facilitate the dispersion conditions.
7. This type of filter in the form of very low energy consumption bio-filter, After running half years.a filter pressure loss is only about 500Pa.
Technical process:
1,The single-stage carbon oxidation BAF is mainly used for removing the carbonaceous organic matter from sewage.
2,The single-stage carbon oxidation BAF with lower loading or carbon oxidation and nitrification filter BAF together, is used for removing carbonaceous organic matter and ammonia nitrogen in the wastewater of nitrification.
3,The lead bio-filter combined with denitrification, is used for inflow water sufficient carbon source and high outlet water quality requirements for nitrogen.
4,The rear or lead bio-filters for denitrification with plenty of carbon, is used for the inflow water with high nitrogen density,lack of carbon, but the outlet water is strict with nitrogen. (the nitrifying liquid reflux rate for the lead bio-filters can be calculated according to the specific design NO3-N removal and inflow nitrogen and oxygen ratio, plus the amount of carbon .
