The biochemical treatment process of the electroplating wastewater at present mainly adopts a two-stage full-course nitrification-denitrification nitrogen removal process (AOAO). Because the biological inhibiting factors in the wastewater are more, the activity of nitrifying bacteria is easy to be influenced, and the whole-course nitration reaction is difficult to directly and stably occur, the invention adopts the short-cut nitration denitrification tank to replace the first-level AO process and optimizes the process parameters. The electroplating wastewater is firstly subjected to a short-cut nitrification-denitrification reaction to remove 50-70% of organic nitrogen, 50-60% of ammonia nitrogen and 70-90% of nitrate nitrogen, and then the rest nitrate nitrogen and ammonia nitrogen are converted into nitrogen gas to overflow through a coupling whole-cut denitrification-nitrification process, so that the thorough denitrification is realized. The process has high denitrification efficiency, saves organic carbon sources, and can effectively reduce the engineering investment cost and the operation energy consumption cost.
