Problems solved by technology

However, when a certain amount of MBBR filler is added to the existing MBBR tank, the uppermost MBBR filler will float upwards due to buoyancy, forcing the uppermost MBBR filler to float on the surface of the sewage, so that the MBBR filler cannot effectively treat the MBBR tank. sewage for treatment

Embodiment

[0021] Such as figure 1 , figure 2 As shown, a method for improving the anaerobic nitrification efficiency of MBBR ponds in the present invention comprises the following steps: first inject sewage to be treated in the pool body 13, and then pull the filter screen 5 upwards through the adjustment rod 10, so that the filter screen 5 is uniform Located on the uppermost layer of the pool body 13, then put the MBBR filler 3 into the pool body 13 through the feeding port 15, and then push the bottom filter screen 5 through the adjustment rod 10, so that the filter screen 5 limits the MBBR filler 3 below the filter screen 5 , then drop into the MBBR filler 3 in the pool body 13 through the feeding port 15, then promote the second filter screen 5 by the adjusting rod 10, continue to limit the MBBR filler 3 to the bottom of the filter screen 5, repeat the above steps repeatedly, The MBBR filler 3 is positioned under the filter screen 5 , and finally the aeration device 1 is turned on...

Abstract

The invention discloses a method for improving the anaerobic nitrification efficiency of an MBBR pool. The method comprises the following steps: injecting to-be-treated sewage into a pool body; upwards pulling filtering nets by an adjusting rod, so that the filtering nets are positioned on the uppermost layer of the pool body; throwing MBBR fillers into the pool body through a feeding opening; pushing the downmost filtering net by the adjusting rod, so that the filtering net limits the MBBR fillers to be under the filtering nets; throwing MBBR fillers into the pool body through the feeding opening; pushing the second filtering net by the adjusting rod; likewise, continuously limiting the MBBR fillers to be under the filtering net; repeating the steps repeatedly, so that the MBBR fillers are positioned under the filtering net; opening an aeration device and conveying oxygen to the pool body through an aeration pipe.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a method for improving the anaerobic nitrification efficiency of an MBBR pool. Background technique [0002] As we all know, with the process of modern industry and the rapid expansion of population, the problem of water pollution has become one of the social focuses. At present, the methods of sewage treatment mainly include activated sludge method and biofilm method: activated sludge method has been used since the 20th century Since its inception in the UK at the beginning, after decades of development and innovation, it has had a variety of operating modes. At the same time, it has gradually become a relatively mature process recognized by everyone due to its excellent sewage treatment effect; the biofilm method uses biological substances attached to the filler A process for purifying water bodies has also been rapidly developed and improved in recent years. It has been proved ...
