1, the common bacteria for denitrification are denitrifying bacteria, nitrifying bacteria and compound bacteria.

Denitrifying bacteria are excellent strains extracted from nature, cultivated and domesticated by advanced bio-genetic engineering technology, fermented and sealed with unique enzymes and nutrients, which can quickly produce nitrate reductase and nitrite in denitrification reaction.

Reductase reduces nitrate and nitrite to nitrogen (N2) or nitrous oxide (N2O) to purify sewage.

2. (Sweet) Denitrifying bacteria are bacteria that can cause denitrification. It is mainly used to improve the denitrification capacity of sewage treatment system, and is usually used in anoxic tanks, anaerobic tanks and other areas.

3. Under normal circumstances: dosage: 300ppm-500ppm, and the dosage ratio can be appropriately increased or decreased according to the sewage situation.

Dissolve in water according to the ratio of 1:6, add into anoxic tank, add glucose, stir and cultivate, after 12 hours, activate microorganisms, attach to the bacterial bed for reproduction, and reach an active state. It is suggested to adjust the influent in stages to reduce the influence on microorganisms. Open 1/3 of normal water inflow on the first day of operation, open 2/3 on the second day, and fully open on the third day. If the design of water inlet is too small, it can be fully opened at one time.

Function:

1. Super removal of total nitrogen, the effective rate is 90~95%.

2. Nitrate is super reduced to nitrogen.

3. Accelerate sludge settling in sewage.

4. Improve denitrification efficiency and maintain the long-term stability of nitrification in the system.

5. Stabilize the environmental order in the denitrification process with the dominant strain status.

6. Complement with nitrifying bacteria to improve the sewage treatment effect.

7. Effectively inhibit viruses, germs and parasites.

8. For the water body with excessive algae reproduction, it can consume a lot of nitrogen nutrition, cut off the nitrogen nutrition of algae and inhibit algae reproduction.

Effectively purify the water body, and the water color is good.

9. Excellent international strains combined with local strains have strong vitality and can adapt to all kinds of refractory wastewater.

10. Combined with domestic technology, the local fermentation production process has strong adaptability to the local environment.

1 1. Combined with the top domestication technology, the natural strain has fast propagation and strong stress ability, and can naturally evolve against harsh environment.

12. Denitrification can be carried out under both aerobic and anaerobic conditions, and the aerobic denitrification effect is weak.
