Complex composition: The wastewater from the production of new energy batteries contains various chemical substances, including inorganic salts, organic compounds, heavy metal ions, etc. Among them, inorganic salts mainly include sulfates, nitrates, etc; Organic compounds mainly include alcohols, esters, ketones, etc; Heavy metal ions mainly include nickel, cobalt, manganese, etc.

High temperature: Due to the need for a high-temperature environment during the production process, the wastewater temperature is generally between 50-80 ℃.

Dark color: Due to the presence of various organic compounds and heavy metal ions, the wastewater from the production of new energy batteries presents a darker color, generally dark yellow or dark brown.

High oil content: Production equipment may leak lubricating oil during operation, resulting in a high oil content in wastewater.
