The submersible sludge return pump is a product developed based on the submersible mixer production technology, using submersible motor production technology. This pump is the second sewage treatment plant mixed liquid reflux and denitrification equipment. Mainly used in municipal engineering, sewage treatment, environmental engineering and other industries, can also be used in ground drainage, irrigation, waste water treatment in micro-lifts and large flow places that need to be recycled. The sludge return pump currently has a wide range of applications in the treatment of chemical processes, and it plays an important role in the treatment of sewage sludge.

1. First clarify the difference between the active creation method and the biofilm method. The biofilm method uses the filler as the biological carrier, and the activated sludge method uses the activated sludge binding mass as the biological carrier. The biofilm method has fixed fillers, so that probiotics are not easy to lose. The activated sludge method is easy to flow out biological bacteria, so part of the sludge is returned and continues to function as a carrier. On the other hand, part of the lost activated sludge bacteria can be recovered to replenish the lost carbon source and discharge the excess sludge.

2. The mud age is not 20 days, and some are short or long. Although the mud age is relatively short, it has become mud slag, but the mud slag continues to be the carrier and has no effect on replenishing the lost carbon source.

3. For the activated sludge method, it is very important to properly maintain a specific amount of sludge. Because it can ensure the implantation conditions of biological bacteria. According to the sufficient mud in the pool water into the shape of cotton, you can also observe the working status of the device.

4. The biofilm method generally does not need to return to the mud. This is because the biological bacteria have stable implantation conditions, and the activated sludge is not easily lost. However, if the implanted biological bacteria drop unexpectedly due to improper operation, mud counter-current must be carried out, and it may be possible to re-invest in active mud from foreign aid.

5. The more important point of the sludge countercurrent is that the removal of ammonia nitrogen has a non-negligible effect.

The sludge backflow process of the sludge return pump can also play a role in promoting water purification. Mainly reflected in two aspects. The flower particles in the mud are separated from the adsorbent, the suspended matter in the water, and the precipitate formed by the reaction. At the same time, the precipitate produced by the reaction plays a core role in crystallization, causing the polymer to gradually grow and speed up the sedimentation and separation. The clean water sludge countercurrent presoaking-bridging filtration and collision solidification in the purification process section, the sludge contains more alum blooms, and many nets are formed during the formation process. At this time, the sludge layer seems to prevent small suspended matter The filter mesh that passes through with the polymer has a bridging filtering effect.
