化学催化法脱除模拟地下水中硝酸盐氮
Chemical catalytic performance on nitrate removal of simulated groundwater
摘要
Abstract
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.关键词
