1. Product introduction and advantages

Denitrifying bacteria contain rich enzyme systems that can efficiently decompose a variety of water-soluble organic matter in water, provide electron donors for denitrification, and quickly reduce nitrate nitrogen (NO3-) and nitrite nitrogen (NO2-) into nitrogen gas. , the bacteria have good tolerance to salt, high and low temperatures, and toxic substances, and can significantly increase the abundance of sludge denitrifying bacteria, greatly increase the sludge denitrification rate and the effective utilization of carbon sources, and reduce operating costs. This product complies with the principles of non-toxic, pollution-free, no secondary pollution and harmless to human body.

2. Mechanism of action

Under anaerobic conditions, the bacteria reduce nitrate nitrogen (NO3-) and nitrite nitrogen (NO2-) to nitrogen gas. At the same time, the bacteria can also carry out denitrification reaction under aerobic conditions, but the denitrification efficiency is lower than under anaerobic conditions.

3. Application advantages

(1) It starts up quickly and does not require a long period of acclimatization. A good denitrification effect can be achieved in 2 to 3 days.

(2) Significantly improve the sludge denitrification rate and the effective utilization rate of carbon sources, and reduce operating costs.

(3) The total nitrogen index of the effluent is stable. When impacted by toxic substances, the system can recover quickly in a short period of time. (4) It increases the abundance of sludge denitrifying microorganisms and continuously protects the biochemical system. It is an advanced total nitrogen solution.

4. Physical and chemical indicators

5. Product features

(1) Using nitrate and nitrite as substrates, nitrogen gas is formed by reduction.

(2) The generation cycle of bacterial strains is short and it is easy to form dominant bacterial groups in sludge.

(3) Contains a rich enzyme system that can efficiently degrade various water-soluble organic matter in water and provide electron donors for denitrification.

(4) The bacteria are highly tolerant, resistant to acid and alkali, high temperature, and have good tolerance to toxic substances.

(5) It can exert good denitrification effect under the conditions of 6~40℃.

6. Usage method and scope

Before normal use, a small test experiment can be carried out in the laboratory. The method is as follows:

(1) Take a certain amount of wastewater to be treated, such as 500mL or 1L (it can be a mud-water mixture at the end of the aeration tank).

(2) Weigh a certain amount of denitrifying bacteria (such as 1g/L, etc.) and add it to the wastewater to be treated;

(3) Stir for about 2 to 5 hours, control DO<5mg/L, and carry out denitrification reaction;

(4) Determine the residual nitrate nitrogen and nitrite nitrogen values in the water.

On-site use:

[Dosing amount]: Under normal circumstances, adding 2 to 10g of this product per ton of wastewater can achieve better denitrification effect. The specific dosage is determined according to the on-site working conditions;
[Conditions of use]: Applicable water The pH value range is 6-11, and the effect is better when it is neutral or alkaline. It is recommended to add it in the front section of the anoxic tank.

7. Main uses

It is suitable for municipal sewage treatment plants, as well as anoxic systems for the treatment of various industrial wastewaters such as chemical wastewater, pharmaceutical wastewater, printing and dyeing wastewater, garbage leachate, and food wastewater, and is used to enhance the removal of nitrate or nitrite nitrogen in sewage.

8. Packaging and storage

Liquid products are packaged in plastic barrels, with a net weight of 25kg/barrel or 1 ton/barrel. The storage period is 3 months. If precipitation occurs during this period, it needs to be shaken before use, and the efficacy will not change. Store in a cool and ventilated place and keep it sealed, avoiding high temperature and sunlight. This product is best stored at 4℃.

Solid products are packed in plastic barrels, with a net weight of 10kg per barrel. The storage period is 1 year. Store in a cool and ventilated place in a sealed container, avoid high temperature and sunlight, and prevent contamination from toxic substances and moisture during transportation.
