Abstract
The utility model relates to a sewage treatment technical field, system that in particular to biology was denitrogenated. An one -level oxygen deficiency pond, the good oxygen pond of one -level, second grade oxygen deficiency pond, the good oxygen pond of second grade are constituteed, and the good oxygen pond of one -level oxygen deficiency pond and second grade sets up water inlet and delivery port respectively, all sets up bio - packing layer in one -level oxygen deficiency pond, the good oxygen pond of one -level, second grade oxygen deficiency pond, the good oxygen pond of second grade of processing system is denitrogenated to high -efficient second grade oxygen deficiency biology, by communicateing in proper order. Furthermore, good oxygen pond of one -level and the good oxygen pond of second grade are equipped with the air hose that leads to bottom of the pool portion from pond upper portion, and the micropore aeration system is connected to the air hose bottom. The utility model discloses setting up of second grade oxygen deficiency / good oxygen system has reduced the phegmal reflux of nitrifying liquid, but the lowering system efficiency has improved the efficiency of getting rid of of ammonia nitrogen and total nitrogen greatly.
Description
Technical field
This utility model relates to technical field of sewage, particularly to the system of a kind of biological removal of nitrogen.
Background technology
Denitrogenation is the process denitrogenated waste water for preventing body eutrophication.It is generally divided into physical-chemical process and bioanalysis denitrogenation two kinds.Physical-chemical process has air stripping denitrogenation, ion exchange, chlorine facture etc., seldom uses.In practice, waste water is processed more by the biological denitrificaion methods using nitration and opposite nitration.The most the suspicion solid/liquid/gas reactions in activated sludge process, biomembrance process processing procedure and good solid/liquid/gas reactions are gone out multiple processing routine through various forms modular design.There is the problems such as treatment effeciency is low, energy consumption is big in the most various technology of denitrogenating.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of efficient two grades of anoxia biological removal of nitrogen processing systems.
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of efficient two grades of anoxia biological removal of nitrogen processing systems, it is made up of the one-level anoxic pond being sequentially communicated, one-level Aerobic Pond, two grades of anoxic pond, two grades of Aerobic Ponds, one-level anoxic pond and two grades of Aerobic Ponds are respectively provided with water inlet and outlet, are respectively provided with biologic packing material layer in one-level anoxic pond, one-level Aerobic Pond, two grades of anoxic pond, two grades of Aerobic Ponds.
Further, described one-level Aerobic Pond and two grades of Aerobic Ponds are provided with and lead to the air hose bottom pond from top, pond, connect micro-pore aeration system bottom air hose.
This utility model has the advantages that
The setting of two grades of anoxia/aerobic systems of this utility model decreases the capacity of returns of nitrification liquid, it is possible to decrease system energy efficiency, substantially increases the removal efficiency of ammonia nitrogen and total nitrogen.Can be used for dyeing waste water, municipal sewage etc. denitrogenates process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of efficient two grades of anoxia biological removal of nitrogen processing systems, 5 are formed by the one-level anoxic pond 2 being sequentially communicated, one-level Aerobic Pond 4, two grades of Aerobic Ponds of 3, two grades of anoxic pond, one-level anoxic pond 2 and two grades of Aerobic Ponds 5 are respectively provided with water inlet 1 and outlet 6, are respectively provided with biologic packing material layer 7 in one-level anoxic pond 2, one-level Aerobic Pond 4, two grades of Aerobic Ponds 5 of 3, two grades of anoxic pond.
Further, described one-level Aerobic Pond 3 and two grades of Aerobic Ponds 5 are provided with and lead to the air hose 8 bottom pond from top, pond, connect micro-pore aeration system 9 bottom air hose 8.
Waste water is initially entered one-level anoxic pond 2 by water inlet 1, carry out preliminary denitrification denitrogenation, enter back into one-level Aerobic Pond 3 and carry out preliminary Nitrification, subsequently into two grades of anoxic pond 4, carry out deepening denitrification denitrogenation, finally enter two grades of Aerobic Ponds and carry out deepening Nitrification, refluxed by Digestive system, strengthen ammonia nitrogen and the removal effect of total nitrogen, flow out eventually through outlet.
Embodiment described above only have expressed embodiment of the present utility model; it describes more concrete and detailed; but therefore can not be interpreted as the restriction to this utility model the scope of the claims; in every case the technical scheme using the form of equivalent or equivalent transformation to be obtained, all should fall within protection domain of the present utility model.
