Background
In order to realize the advanced treatment of the total nitrogen in the sewage and further reduce the index of the total nitrogen pollutants in the sewage, more and more denitrification reactors are produced in response to the operation, and when the biological denitrification reactors are normally operated, on one hand, the resistance loss of a filter tank is continuously increased along with the increase of trapped matters, and the liquid level is continuously increased; on the other hand, the biological membrane is aged gradually, and the denitrification efficiency is reduced gradually; then a large amount of nitrogen reduced from the sewage is accumulated in the gaps of the filter material. These conditions lead to an increasing resistance to flow and a reduction in the efficiency of the process, so that all types of bioreactors must be back flushed after a certain period of operation.
