Further, know-why of the present invention is specially:
The water inlet of the first sbr reactor device is the mixed solution of former water and ASBR effluent recycling liquid, after water inlet, first carry out anoxia stirring, can utilize the organic carbon source in former water that the nitric nitrogen denitrification in ASBR effluent recycling liquid is removed, utilized more fully the organic carbon source in former water, avoided the waste of carbon source simultaneously.In denitrification process, denitrifying bacterium utilizes NO 2 --N is electron acceptor(EA), and organism is electron donor, by NO 2 --N is reduced to N 2, oxidation state material in reactor is constantly reduced, ORP value can constantly decline, and after denitrification finishes, reactor is in anaerobic state, and ORP declines rapidly, now occurs unique point A.Denitrification finishes rear beginning aeration and only carries out organic removal.In mature leachate, contain a small amount of organism and a large amount of ammonia nitrogens, and organism can produce adverse influence to follow-up Anammox reaction.Owing to only carrying out organic removal in the first sbr reactor device, in organic matter removal reaction process, the CO of generation 2by stripping, make pH increase, the nitration reaction of carrying out after organic matter removal can consume basicity declines pH, now there will be unique point B.According to above unique point, can judge exactly the reaction process of denitrification and organic matter removal, after denitrification finishes to complete with organic matter removal, stop stirring and aeration, avoid the oxidation of ammonia nitrogen.
The water inlet of the second sbr reactor device derives from the water outlet of the first sbr reactor device, and its Main Function is that the water outlet of the first sbr reactor device is carried out to short distance nitration, for follow-up Anammox reaction provides nitrite nitrogen matrix.After the second sbr reactor device water inlet, start aeration and stirring, under the associating restraining effect of high free ammonia FA and high free nitrous acid FNA, the second sbr reactor device has been realized short distance nitration, the oxidation state nitrogen of its water outlet is mainly existed with nitrite nitrogen form, nitrate nitrogen content is extremely low, for follow-up ASBR reactor provides nitrite nitrogen matrix.Because nitration reaction can consume basicity, pH is declined, CO after nitrated end 2stripping effect make pH occur increase, therefore there is unique point C.
The water inlet of ASBR reactor is the mixed solution of the first sbr reactor device water outlet and the second sbr reactor device water outlet, and this mixed solution is mixed by the 40% and second sbr reactor device water outlet of the first sbr reactor device water outlet.Owing to having carried out organic removal in the first sbr reactor device, so time organism very little on the impact of Anammox, ASBR reactor can maintain the reaction of good Anammox.Because ASBR reactor adopts continuously, intake, the basicity that Anammox reaction is produced is neutralized, and in reactor, pH remains unchanged substantially, and reaction finishes rear pH meeting slow decreasing, now occurs unique point D.Through Anammox reaction, nitrogens most in former water remove the form with nitrogen from reactor, realize denitrogenation completely truly.
Advantage of the present invention is, whole reactive system is in the first sbr reactor device, the second sbr reactor device and ASBR reactor, the nitrite nitrogen that utilizes original ammonia nitrogen in percolate and short distance nitration to produce, the Anammox technology of application autotrophic denitrification is carried out advanced nitrogen processing to percolate, further denitrogenation refluxes the water outlet of ASBR reactor 70% simultaneously, save energy not only, and without additional carbon, just can deviate from most of total nitrogen, greatly reduce processing costs and the capital cost of sewage disposal.System influent ammonium concentration 2000 ± 100mg/L, water outlet ammonia nitrogen and nitrite nitrogen are all lower than 10mg/L, and about the about 60mg/L of total nitrogen, under the condition of not adding outer carbon source, system denitrification percent reaches more than 95%.
Whole system is controlled in real time by online DO, pH and ORP value sensor, accurately judges each elementary reaction terminal, saves reaction times and the energy.Whole technique is completed by process real-time control system, and bookkeeping is convenient, and working cost is lower, system anti impulsion load and difficult generation sludge bulking.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
