Description
Technical field
The present invention relates to a kind of sewage denitrification processing system, belong to sewage treatment field.
Background technology
With raising of the country to sewage treatment plant's discharge standard, denitrification deep-bed filter is obtained with its unique advantage
Widely apply.Compared to other techniques, denitrification deep-bed filter technological process is simple, effect stability, and effluent quality is good, investment
Few, energy consumption is low, economical and efficient.
Nitrate nitrogen is mainly first converted into nitrogen by denitrification deep-bed filter using denitrifying bacteria using the carbon source in water, complete
Total nitrogen removes into sewage.Since the speed of denitrification deep-bed filter inner filtering layer discharge nitrogen has the upper limit, when nitrogen produces speed
When degree is more than the velocity of discharge, the nitrogen produced in denitrification process can be gathered gradually in filtering layer, blocked the gap of filtering layer, caused water
" gas blocks up " phenomenon can not be produced normal through filtering layer.Produce gas and block up directly related with the concentration of nitrate nitrogen in sewage, cause nitre
The application of the higher sewage denitrification deep-bed filter of state nitrogen content is restricted.
In addition, carbon source adds in denitrification deep-bed filter filter process amount and levels of precision directly affect operating cost
With denitrification denitrogenation effect, since denitrification deep-bed filter has excellent denitrification capability, at denitrification deep-bed filter
The content of total nitrogen is far below national clear water drainage requirement after reason, causes substantial amounts of production capacity to waste.
In existing patent CN204803073U, disclose a kind of a kind of denitrification depth bed applied to advanced treatment of wastewater and filter
Pool structure, using setting back-flushing structure in the patent, can denitrification deep-bed filter occur gas it is stifled when, utilize reverse gas
Stream or current dredge filtering layer, and the program can alleviate gas to a certain extent and block up phenomenon；But it is the absence of adding carbon source
Structure, can not take into account at the same time carbon source utilized by microorganism, in filter tank carbon source uniformly, protection filter tank structure and other effects.
The content of the invention
It is an object of the present invention to solve the above problems, the present invention is devised, reduces shadow of the sewage total nitrogen concentration to denitrogenation
Ring, expand the water inlet scope of application of denitrification deep-bed filter, the gas for reducing denitrification deep-bed filter blocks up probability, extends the system and connects
