In this paper

the nitrogen removal efficiency and mechanism by the chemical catalytic particle carrier

i.e.

the self-made active catalytic solid particle carrier and its influence factors such as HRT

initial pH and the quality of influent were studied and analyzed. The reaction kinetic model was established. The result showed that the nitrogen removal by self-made carrier is 3 order reaction and the initial concentration of ammonia in water had inhibitory effect on the reaction. Nitrogen removal rate reached 88.7% when HRT was 2 h

and was up to 90% no matter in acidic

neutral or alkaline conditions. Compared to normal zero-value iron or ferric carbon micro electrolysis

the chemical catalysis particle carrier was more efficient and had no particular requirement on influent pH.
