Abstract:
An ecological filter is constructed for successful nitrification instead of conventional filter system. Zeolite and coal cinder compose main substrates of this micro-ecological filter. Nitrogen contamination removal process is investigated in three different systems (D system, A system and N system) contrastively. Dominant bacteria colony is applied to intensify the remedying process. The data showed that, NH4+-N removal efficiency in D system is better than those in the other two systems for zeolite absorption, nitrogen removal efficiency by nitrification increased. Functional bacterium consortium can adsorb much NH4+-N in short time. Most nitrogen removal is hastened through nitrification by abundant nitrous and nitride bacterium in dominant colony. That dominant consortium keeps high activity in long time. Phosphorus removal is improved by abundant aboriginal bacterium. Complex functional bacterium is benefit to decompose organic phosphorus and its removal.
Key words: ecological filter bacteria colony nitrogen contamination
