Domestic Sewage Treatment in a Mongolian Factory Zone

This project focuses on the domestic sewage treatment of a factory zone in Mongolia. The sewage is mainly generated from employees' daily activities in the zone, including catering, accommodation, office cleaning and other daily operations. Combined with the adaptability to the local climate and environmental conditions of Mongolia and in line with the actual needs of the factory zone, Yimei has adopted a tailored treatment solution.

In the pretreatment stage, reinforced concrete-structured grille tanks, grit chambers and oil separation tanks are constructed to intercept large-particle pollutants such as domestic waste and debris. For the core biochemical treatment stage, a low-temperature resistant optimized core process is applied. By acclimating cold-tolerant microorganisms, the hydraulic retention time is extended and the organic matter degradation efficiency is improved. Finally, the sewage undergoes advanced treatment including filtration and disinfection processes, which ensures the effluent meets the local discharge standards of Mongolia and realizes the recycling of water resources.
