Historical background:

Controlling air pollution requires the participation of local governments at all levels, enterprises and the general public, so that the existing laws, regulations, technologies and measures can be truly implemented, and strict implementation of the supervision and accountability system is the key move.

China's water environment situation is still very grim, and the total discharge of water pollutants is still huge. According to statistics, China's annual chemical oxygen demand emissions are about 24 million tons, and ammonia nitrogen emissions are about 2.45 million tons, far exceeding the current environmental capacity.
