In the practice of ammonia nitrogen wastewater treatment

In recent years, Shandong has achieved remarkable results in the treatment of ammonia nitrogen wastewater. Through a series of scientific and effective measures and technological innovations, it has effectively reduced the ammonia nitrogen content in industrial wastewater, protected the water environment, and promoted green and sustainable development.

　　1. Technological innovation leads governance to new heights

　　Shandong has actively introduced and independently developed a number of advanced technologies for ammonia nitrogen wastewater treatment. Among them, the integrated technology of short-range nitrification and anaerobic ammonium oxidation has become a powerful tool for treating high-ammonia nitrogen wastewater. This technology greatly improves the ammonia nitrogen removal rate to more than 95% by realizing two processes, anaerobic ammonium oxidation and short-range nitrification, in one reaction unit. At the same time, it reduces space requirements and energy consumption, reduces the amount of residual sludge generated, and significantly improves wastewater treatment efficiency.

　　II. Engineering practice demonstrates governance effectiveness

　　In the practice of ammonia nitrogen wastewater treatment in Shandong, a number of successful engineering cases have emerged. By adopting advanced wastewater treatment technology, the ammonia nitrogen content in pig pen flushing water, washing wastewater and domestic sewage has been greatly reduced to meet the emission standards. The successful implementation of this project has not only improved the breeding environment, but also enhanced the company's environmental protection image and market competitiveness.

　　III. Promotion and Strengthening of Supervision

　　A series of policies and measures have been introduced to promote the in-depth development of wastewater treatment. At the same time, the supervision of wastewater discharge enterprises has been strengthened to ensure the normal operation of wastewater treatment facilities and the discharge standards. In addition, the special action to control total nitrogen in rivers entering the sea has been strengthened. By strengthening the control of farmland drainage and drainage upstream of rivers entering the sea, and the control of garbage in coastal ports and docks, the ammonia nitrogen content in rivers entering the sea has been effectively reduced.

　　In summary, Shandong has achieved remarkable results in the treatment of ammonia nitrogen wastewater. Through efforts in technology innovation, engineering practice and policy promotion, it has effectively protected the water environment and promoted green and sustainable development. In the future, we will continue to increase wastewater treatment efforts, promote the application and promotion of more advanced technologies, and contribute to building a beautiful Shandong.
