What are the effects of MBBR filler film hanging

MBBR filler has the advantages of large specific surface, good water absorption and affinity, high biological activity, fast film coating, very good solution effect, and long service life. MBBR microbial packing is very different from ordinary fixed bed reactor packing, and there are many factors that affect whether the film can be coated quickly and reasonably.

What is the development prospect of MBBR packing?
1. Effect of dissolved oxygen (DO) on MBBR process.
In the whole process of simultaneous nitrification-hydrolysis acidification tank microbial denitrification, DO concentration is an important limiting factor affecting simultaneous nitrification reaction-hydrolysis acidification tank. By manipulating the DO concentration, aerobic or oxygen-deficient regions can be generated at different positions of the extracellular matrix, so as to achieve the physical standard of synchronous nitrification reaction-hydrolysis acidification pool.

2. The influence of hydropower waiting time on MBBR processing technology.
Appropriate hydropower waiting time (HRT) is an important control factor to ensure the cleaning effect and the rationality of project investment. The length of waiting time for hydropower generation will directly affect the contact time between organic compounds in water and extracellular matrix, thereby affecting the adsorption and dissolution efficiency of microbial strains on organic compounds. Therefore, finding economically developed and effective HRT for different wastewater types is a very important issue. The country's scientific research on HRT is not limited to the scientific research of HRT itself, but to grasp the macroeconomics based on experiments.

3. The effect of PH value on MBBR packing process.
The physiological activities of microorganisms are closely related to the pH of the environment. Only under the appropriate pH conditions, microorganisms can carry out all normal physiological activities. If the pH value is too high and the deviation is suitable for the standard value, the catalytic reaction of the cofactor of the microbial strain will be weakened or even subsided. The pH value in the physiological activities of different types of microorganisms has a certain range, which can be divided into pH value and suitable pH value. In a pH environment, although microbial strains can survive, their physiological activities are weak, they are easy to die, and their reproduction speed is greatly reduced.

4. The influence of other factors on the MBBR packing method.
Depending on the criteria for each experiment, there are still many different influencing factors.

5. Effect of temperature on MBBR process.
The role of temperature is crucial to various factors that affect the physiological activities of microbial strains. Appropriate temperature can promote and strengthen the physiological activities of microbial strains; if the temperature is not suitable, it can weaken or even destroy the physiological activities of microbial strains. If the temperature is not suitable, it will also cause changes in the shape and physiological characteristics of microbial strains, and even lead to the death of microbial strains. The suitable temperature for microbial strains means that under these temperature conditions, the physiological activities of microbial strains are strong and abundant, mainly manifested in the degree of reproduction.
