The invention discloses a high ammonia nitrogen and nitrate nitrogen inorganic wastewater treatment process. The process comprises the steps: pretreatment; wastewater shunting; and wastewater treatment: carrying out biological treatment by an oxygen-free process and an aerobic biological treatment process. According to the process disclosed by the invention, the retention time of sludge is controlled by utilizing a membrane in the aerobic tank, so that the retention time of the sludge can be prolonged, and the retention rate of microorganisms in the process is effectively ensured; two reflowsare arranged for realizing anaerobic short-cut denitrification nitrogen removal in an anaerobic section, so that nitrification and denitrification separation is realized, nitrogen can be removed moreefficiently and stably, and addition of an external carbon source can be effectively avoided by controlling the amount of a liquid obtained after reflux nitrification. 本发明公开了一种高氨氮与硝氮无机废水处理工艺，包括：预处理；废水分流；废水处理：进行无氧工艺和好氧生物处理工艺的生物
