At Inner Mongolia Baogang Group Environmental Engineering Research Institute Co, beautiful goldfish swim in the office aquarium. The water in the aquarium comes from the group's wastewater treatment system.

The wastewater treatment project is the largest energy-saving and environmental protection project invested in by Baogang, and it is supported by combined gas-steam cycle power generation technology. The project was recently put into operation, marking a new benchmark for the company's industrial wastewater treatment capacity.

This project mainly treats the wastewater from Baogang's coking systems and other processes. The incoming water to these systems has high chemical oxygen demand, high ammonia nitrogen, low organic matter, and other characteristics, posing significant treatment challenges.

The wastewater treatment project adopts a combination of physical, chemical, and biological processes, including gravity oil separation, mechanical filtration, and ozone treatment. The process technology involved is mature, stable, and reliable.

Currently, the water treated by this project meets the quality standards for reused water in terms of parameters such as ammonia nitrogen, COD, and pH.

At the same time, the wastewater treatment project ensures the normal operation of the company's newly built power generation project. It also improves water quality while reducing external water consumption, as well as promotes the development of the enterprise's circular economy.
