Bioreactors come in many forms. To make the bioreactor run well, we must first have a deep understanding of the bioreactor and reaction characteristics, which is the concept of bioreactor engineering.
Bioreactor engineering focuses on the characteristics of bioreactor itself, such as the relationship between its structure, operation mode and operating conditions on cell morphology, growth and product formation.
It is combined with biological reaction engineering to solve the problem of selecting the best bioreactor and the best operating conditions for various biological reactions.
Membrane bioreactor is a new and efficient sewage treatment technology which combines membrane separation and biological treatment. The denitrification mechanism of industrial nitrogen-containing wastewater includes two basic processes: nitrification and denitrification. Nitrification refers to the process of transforming ammonia nitrogen into nitrate nitrogen, which is mainly completed by two aerobic autotrophic bacteria, nitrosobacteria and nitrifying bacteria.
Toray mbr membrane technology firstly removes biodegradable organic pollutants from water through activated sludge, and then forcibly intercepts activated sludge and most suspended substances in the bioreactor by membrane modules, thus realizing solid-liquid separation of purified water and activated sludge, thus strengthening biochemical reaction and improving sewage treatment effect and effluent quality.
The MBR treatment process has obvious treatment effect on COD in wastewater from nitrogen fertilizer industry, and its biochemical strain has a short acclimation period, showing a stable effect from the third day. In the stable treatment stage and normal operation stage, a high COD removal rate can be maintained, and the removal rate is basically above 90%. The average outlet COD is controlled below 30mg/L.
