Two-thirds of urban domestic sewage directly enters natural water sources without being treated. The production of urban domestic garbage treatment equipment in China is still small scale and of limited type.
China is a large coal-burning nation, so carbon dioxide and nitrogen oxide emissions are large.
In southern and southwestern regions, acid rain is becoming a serious problem. Therefore, there is much demand for desulfurization and denitration equipment. China s current system of automated environmental monitoring networks is substandard since most of the monitoring is still done by humans. It is inefficient, of low quality, and cannot meet the demands of environmental supervision and management. Therefore, real automated networks are desperately needed.
