Removal of totalnitrogen from black-smelly water by series natural zeolite reaction column with iron-carbon microelectrolysis
The technology of using iron carbon micro electrolysis in series with natural zeolite is used to remove total nitrogen from black and odorous water bodies.The results showed that:(1 )The static experiment determined that the influent pH was 3,the iron carbon ratio was 2:1,the hydraulic retention time of the iron carbon micro electrolysis reaction layer was 120 minutes,the hydraulic retention time of the zeolite layer was 40 minutes,and the total hydraulic retention time of the reaction column was 160 minutes.(2)In the dynamic experiment,the removal rates of NH4+ ,NO3- ,and TN were maintained at around 95％,92％,and 90％,respectively,and could be continuously treated for more than 300 hours.(3)The average removal rates of TN,NO3- ,and NH4+ in the pilot experiment were 83.04％,91.85％,and 88.60％,respectively.The average removal rates of TP and COD were 83.2％ and 89.7％,respectively.
