NOVELTY - Garbage percolate is subjected to flocculation deposit pre-process and hydration pre-acidifying process. The pre-processed material is subjected to anaerobic and aerobic processes, and film separation process. The condensed solution obtained after film separation is oxidized and solid-liquid separated. The aerobic process involves controlling oxygen quantity, nitrating, changing ammonia into nitrous acid, carrying out denitrification, reducing nitrous acid, nitrate and nitrite in refluxing solution, oxidizing ammonia to nitrite and further to nitrate.    USE - Processing of garbage percolate.    ADVANTAGE - Ammonia and nitrogen are removed with high removal ratio. The processing is performed efficiently with low energy consumption. Steady operation of the system is ensured. The oxidation reduction potential in the anaerobic reaction is reduced and anaerobic processing effect is improved.    DETAILED DESCRIPTION - Garbage percolate is subjected to flocculation deposit pre-process and hydration pre-acidifying process in a pre-acidifying pool (4) with iron wood chips or iron dust. The pre-processed material is subjected to anaerobic and aerobic processes, and film separation process. The condensed solution obtained after film separation process is poured into oxidation flocculation reacting pool (17) with ferrous ion and hydrogen peroxide to carry out oxidation flocculation process. Subsequently, the solid in the solution is separated in solid-liquid separation pool (18) and the water after solid-liquid separation is supplied into stable pool (16). The aerobic process involves controlling oxygen quantity using aerobic reactor in nitration pool (7) under aerobic condition, carrying out nitrosification type nitration, changing ammonia into nitrous acid, controlling oxygen quantity to carry out denitrification using oxygen-poor reactor in denitrification pool (8) under oxygen-poor condition, reducing the nitrous acid into nitrogen gas, reducing nitrate and nitrite in refluxing solution into nitrogen gas and nitrous oxide by denitrification bacteria in the secondary denitrification pool (10), oxidizing ammonia to nitrite by nitrosification bacteria in the nitration pool (11) and oxidizing the nitrite to nitrate by nitrobacter.
