Specifically, the rainwater in the factory area flows into the rainwater channel, the rainwater channel is used to collect rainwater, and the rainwater gate is used to control whether the rainwater in the rainwater channel is discharged to the outside. When the rainwater gate is opened, the water in the rainwater channel is discharged outside the factory area. Closed, the rainwater in the rain channel cannot be discharged to the outside of the factory.

COD is a commonly used comprehensive index to evaluate the degree of water pollution, which refers to the amount of oxygen consumed by the use of chemical oxidants (such as potassium dichromate) to oxidize and decompose reducing substances (such as organic matter) in water. Under certain conditions, the amount of oxidant consumed by the oxidation of reducing substances in 1 liter of water sample is used as an indicator, which is converted into the milligrams of oxygen required after all the oxidation of each liter of water sample, expressed in mg/L. COD reflects the degree of water pollution by reducing substances. Since organic matter is the most common reducing substance in water, COD reflects the degree of water pollution by organic substances to a certain extent. The higher the COD, the more serious the pollution.
