Description

Technical Field

[0001] The utility model belongs to the technical field of grinding devices, in particular to a grinding device used for the production of COD remover. Background Art

[0002] Chemical oxygen demand (COD) refers to the amount of oxidant consumed when a water sample is treated with a certain strong oxidant under certain conditions. It is an indicator of the amount of reducing substances in the water. The reducing substances in the water include various organic matter, nitrites, sulfides, ferrous salts, etc., but the main ones are organic matter. Therefore, COD is often used as an indicator to measure the amount of organic matter in the water. The larger the chemical oxygen demand, the more serious the water pollution by organic matter. The sources of these organic pollution may be pesticides, chemical plants, organic fertilizers, etc. If not treated, many organic pollutants can be adsorbed by the sediment at the bottom of the river and deposited, causing lasting toxic effects on aquatic organisms in the next few years.
