Metallurgical industry
There are many products in the metallurgical industry, and the production processes are all in series, which discharges a large amount of waste water and is one of the main waste waters polluting the environment. Circulating water and water quality Stable water recycling is an important measure for metallurgical wastewater treatment. The main features of metallurgical wastewater are large water volume, various types, and complex and variable water quality. Classified according to the source and characteristics of wastewater, there are mainly cooling water, pickling wastewater, dust and gas, flue gas washing wastewater, slag wastewater and wastewater that is condensed, separated or overflowed in the production process. As a major energy consumer in the industry, iron and steel metallurgical enterprises are key industries for energy conservation and emission reduction. Under the premise of meeting the safety of production water, the wastewater after preliminary treatment needs to be treated with ultrafiltration and reverse osmosis membrane to obtain reclaimed water. Reclaimed water is used as the production water source, which not only ensures the requirements of environmental protection and energy conservation, but also ensures the economic benefits of the enterprise.
