From the view of reaction , it combined the SHARON and ANAMMOX processes , so it can be taken place at one reactor. Through more than one years running , it is found that CANON process is taken place in the leachate treatment plant of ShenZhen Xiaping Municipal Solid Waste Landfill Site , at the conditions that DO is about 1 mg/ L , ammonia concentration less than 800 mg/ L and ammonia load less than 0. 46 kgN H + / (m3 ·d) . The results show 4 that ammonia and total nitrogen removal efficiency is above 95 % a
