Before 1949, China was still an agricultural country, with little progress in industry. In just a few decades, China's industry has made a qualitative leap, promoting China from an economically backward agricultural country into the world's largest industrial producer, and made remarkable achievements. The most direct manifestation of the development of industry is the establishment of a large number of factories, the factory will inevitably discharge a large amount of sewage, wastewater in the production process, resulting in water quality deterioration. These industrial wastewater contains a lot of lead, mercury and other harmful chemicals, and its emissions have also caused a certain degree of pollution to people's domestic water.
