Second: in the industrial production process, the general reaction conversion rate can only reach 70% ～ 80%. Part of the unreacted raw materials can be recycled, but finally some of them are transferred into wastewater, waste gas or waste residue due to incomplete or irrecoverable recovery.

Third: cooling water many production processes need a lot of cooling water, such as steel, oil refining and so on. There are two ways of cooling: direct cooling and indirect cooling. Direct cooling is to make the cooling water directly contact with the cooling material, which is easy to become industrial wastewater.
