DENITRIFYING BACTERIA AGENT
【Character of commodity】Powder
【Main ingredients】Main ingredients:Denitrifying bacteria, enzyme, activator, etc
【Living bacterium content】≥20 billion/g
【Range of application】Suitable for the hypoxia system of municipal waste water treatment plants, all kinds of industry chemical waste water, printing and dyeing waste water ,garbage leachate, food industry waste water and other industry waste water treatment.
1.It has processing efficiency with Nitrate and Nitrite, can improve the efficiency of denitrification and maintain the long-term stability of the system of nitrification.
2.The denitrifying bacterium agent can restore quickly from a state of chaos which lead from the impact load and denitrification of sudden factors.
3.Make the influence on Nitrogen nitrification return to least in deficient security system.
【Usage and dosage】：
1.According to water quality index into the biochemical system of industrial waste water：the first dosage is about 80-150 grams/cubic (according to volume calculation of the biochemical pond).
2.If it has too big impact on biochemical system caused by fluctuations feed water, the improved dosage is 30-50 grams/cubic (according to volume calculation of the biochemical pond).
3.The dosage of municipal waste water is 50-80 grams/cubic (according to volume calculation of the biochemical pond).
The test shows that the following physical and chemical parameters for bacterial growth is most effective:
n PH: In the range of 5.5 and 9.5, most rapidly growth is between 6.6~7.4.
n Temperature: It will take effect between 10℃~60℃. Bacteria will die if the temperature is higher than 60℃. If it is lower than 10℃, it will not die ,but the growth of bacteria will be restricted a lot. The most suitable temperature is between 26~32℃.
n Dissolved oxygen: In sewage treatment denitrifying pool, dissolved oxygen content is under 0.5mg/liter.
n Micro-element : Proprietary bacterium group will need a lot of elements in its growth , such as potassium, iron, sulfur, magnesium, etc. Normally , it contains enough elements in soil and water.
n Salinity: It is applicable in salt water and fresh water ,the maximum tolerance of salinity is 6%.
n In use process should pay attention to control SRT solid retention time, carbonate basicity and other operating parameters , for the best effect of this product.
n Poison resistance : Can more effectively resist chemical toxic substances, including chloride, cyanide and heavy metals ,etc.
