Revolutionary Wetlands Transforming Rural Sewage Treatment in China
The study looked at using constructed wetlands to treat sewage in rural areas. By building wetlands in the countryside, researchers found that they could effectively remove pollutants from the sewage. After a trial period, they saw significant reductions in COD, TP, and TN levels in the treated water. The water quality met or exceeded standards for discharge, showing that this method is a cost-effective way to treat pollution from rural areas.
