10 Questions about MBBR Technology
1: how long will it take for the packing to hang up during the low temperature debugging in winter?A: the standard can be well achieved in one month. If the biofilm is actually a process, we divide the biofilm into two angles. the first is that our naked eye can see that there is an obvious biofilm on the filler, which takes seven days, and the second is the time to reach the standard. if this time is in winter, it is probably within a month. The third is the time when the biofilm is fully mature, which will be longer, because from a professional point of view, the biofilm has to go through at least one alternation of winter and summer before the colonies above it can finally be stable. In conclusion, although from an academic point of view, our stability is probably after a winter and summer, from the point of view of our effect, the water can reach the standard within 30 days, and about seven days from the point of view of naked eye recognition. 2. Is it necessary to add additional biological agents in the MBBR treatment process?A: strictly speaking, MBBR does not need to add bacteria, so through reasonable optimization parameters, it can be naturally enriched, such as our nitrifying bacteria or denitrifying bacteria, because its biofilm conditions are conducive to the attachment of related bacteria, for example, anamination is also beneficial to the attachment of our anaminergic bacteria under specific conditions. Well, under special water quality conditions, for example, there are some non-degradable water quality or the source of water quality is relatively single, and some specific bacterial agents have special effects, so they can be used as the initial inoculation, and there is no need to add them later. To sum up, it is not necessary under the condition of domestic sewage, but it can be used as a research proposition to do related research under some specific wastewater conditions3. Some experts in the industry say that the packing is easy to clog and the flow pattern is difficult to control?A: this question cannot be called a problem. It should be a difficult one. It is because of such difficulties that different technical teams and manufacturers can be screened out to overcome the difficulties in order to take the lead in the world. If something goes wrong, it will be gradually eliminated by the market.4. Does MBBR, need denitrification flushing?Answer: the biggest advantage of MBBR is that compared with the traditional biofilm, it does not need backwashing, because its biofilm falls off automatically. From our research, we found that when your biofilm is more active, its extracellular polymer secretion will be more, and its stickiness will be strong. So when it ages, the extracellular secretion decreases, its viscosity weakens, it will automatically fall off in the process of fluidization, and then a new biofilm will grow up, so it does not need to be washed. 5. What is the magic of MBBR?Answer: the core of MBBR is two, one is filler, the other is fluidization, and the filler is used as a carrier. At present, there is not a unified study to show how much influence its performance has, but its shape will have an impact on fluidization, so it is said that flat cylindrical packing is the most widely used at home and abroad. Then the research on fillers has been going on, and you can try to take a look at different fillers. Which is the best. However, from an engineering point of view, the dimensions to be evaluated, such as performance, biofilm speed, final stability, life, wear resistance and so on, so from now on, the core of the suspension carrier is still fluidization.
