The importance and challenges of wastewater treatment


Wastewater is one of the most difficult and environmentally destructive of all water sources generated by human activities. In addition to sources such as domestic sewage, industrial wastewater, and agricultural wastewater, wastewater contains a large amount of organics, salts, heavy metals, bacteria, viruses, and other harmful components, and its direct discharge can cause significant harm to the environment and human health. Therefore, effective treatment of wastewater has become an important cornerstone of sustainable human development.

Wastewater treatment is an important means of protecting the environment and human health, but it also entails many challenges. By promoting advanced wastewater treatment technologies, reducing the cost of wastewater treatment and improving wastewater discharge standards, we can more effectively address the challenges of wastewater treatment and achieve the goal of environmentally sustainable use of water resources.
