Description

technical field

[0001] The invention relates to an industrial wastewater recycling device, which belongs to the technical field of energy-saving devices. Background technique

[0002] Wastewater refers to the general term for water discharged from residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as primary rainwater that flows into drainage pipes and canals. It generally refers to water that cannot be recycled after certain technical treatment or that is difficult to purify after primary pollution and cannot meet a certain standard.

[0003] China is one of the most water-polluted countries in the world, with up to 70 percent of the country's rivers, lakes and reservoirs affected. A national survey showed that nearly 20 percent of the organic pollutants (expressed as chemical oxygen demand) discharged into various water bodies in 2007 originated from industry. These factories pollute vital water re...
