To control the DO of the aeration tank, the push-flow (PFR) or sequential batch (SBR) activated sludge method is used to make the sludge alternately undergo anaerobic and aerobic conditions. The micelle bacteria can ingest, transform and store the matrix under anaerobic and aerobic alternate conditions, thereby competitively rejecting filamentous bacteria with poor ability under this condition.
Adjust the nutrient ratio of wastewater. For treatment systems that increase the SVI value due to lack of N and P and cause sludge expansion, it is necessary to add N/P to the influent water.
Based on the above, when the sludge expands, the environmental conditions of the microorganisms in the aeration tank should be changed in time. In the sludge system where there are two major types of microorganisms-micellar bacteria and filamentous bacteria coexist and compete with each other, Create environmental conditions suitable for the growth of micellar bacteria, so that filamentous bacteria cannot grow in an advantageous manner, so as to achieve the purpose of improving the sedimentation and compression performance of sludge and controlling or preventing sludge expansion. The following table shows the abnormality and analysis of sludge properties.
Frequently Asked Questions.
1. Why does the film hang quickly after adding sucrose? Is it true that pure HDPE materials have been eliminated?
Answer: No, it is not. With the addition of sucrose and other additives, although the film formation will be fast, but after a long time, the loss of sucrose will cause the early attached microorganisms to fall off. It will also lead to a decrease in the quality of the MBBR carrier, an unstable structure, more easily broken, and an increase in cost. MBBR made of pure HDPE material has a service life of more than 15 years.
2. Why is the oxygenation pool very turbid? I increased the aeration significantly!
Isn't it said that the more aerated the aerobic pool is, the better?
Answer: Because the aeration volume of the aerobic pool seems simple, it should be just right in fact. If the aeration is insufficient, the nitrification effect will be poor, the fluidization effect will be poor, and the nitrifying bacteria will not be fully cultivated. However, too much aeration will cause the sludge to swell and sink, causing the water to be turbid. Therefore, specific analysis of specific issues requires aeration control for specific issues.
3. After adding MBBR bio-filler, do I need to add bio-clay?
Answer: It depends on the situation, if in the anoxic-anaerobic stage, bio-sludge is unavoidable and must be added. However, in an aerobic pool, if the temperature is moderate and the nitrification effect is good, it can be omitted. If the number of bacteria is insufficient, an appropriate amount of bioclay can be added to promote the rate of film formation.
4. How much MBBR filler should be added? half? Or top up?
Answer: Taking the aerobic pool as an example, if there is biological sludge, the amount of MBBR biological filler is 30%. If there is no biological sludge, pure MBBR material is used for nitrification reaction, and the addition amount can reach 70% or even 80%. Of course, adequate aeration and agitation are required.
