The petrochemical industry now increasingly uses MBBR to treat wastewater. Do you know the reason for this?
As we all know, the pollutants produced by the petrochemical industry are unique. The wastewater produced by it contains a large amount of nitrogen, ammonia and toxic substances, which has poor biodegradability and difficulty in treatment, and the water quality varies greatly.
MBBR bio has many advantages. It not only occupies less land and saves valuable land resources, but also has better water quality after treatment, which is convenient for reclaimed water reuse and greatly reduces the amount of sludge.
At the same time,biomedia mbbr has a strong ability to remove nitrogen and ammonia, and its energy consumption is also greatly reduced, which saves costs for industrial production.
More importantly, the density of the filler of the biofilm produced in MBBR is very close to that of water. For example, in the process of Linpor MBBR in Germany, porous foam plastic particles are added. Media bio is kept in a fluidized state under aeration and stirring. The above biofilm is in extensive contact with sewage, and has been in contact for many times, which improves the purification ability.
The specific surface area of the suspended carrier is relatively large, and the number of microorganisms on its surface and inside is large, making the sludge concentration 6-10 times that of CAS. The reaction tank fluidizes on media mbbr with water, which can grow a large number of filamentous bacteria to keep the flora rich; the suspended biomedia is washed by the water, and the membrane will automatically fall off after aging, ensuring the membrane's activity.
Therefore, MBBR is very suitable for wastewater treatment in the petrochemical industry. It is generally welcomed by practitioners in the petrochemical industry and has been actively promoted and applied in this industry.
