| Abstract: | As a new treatment of nitrate-nitrogen in groundwater.the internal electrolysis-precipitation process is studied in this paper.The best condition for nitrate-nitrogen removal is: reaction time is 90min;carbon particle size is 2mm;ironcarbon ratio is 15:1;dosage of reagent is 5g/L;catalyst-iron ratio is 25:1(internal electrolysis);pH values in solution is 11;reaction time is 40min(precipitation).The results show that in the best condition the removal ratio of nitrate nitrogen reaches over 99% and the concentration of NO2-N,NH3-N,NO3-N are less than the national standard. |
