With the development of the economy, one of the crises facing the world is the scarcity of water resources and pollution. In order to solve this problem, feasibility researchers have developed reclaimed water reuse equipment. Which industries' wastewater can be recycled and reused?
Not all sewage can be recycled, and its measurement standards include evaporation residue, dissolved substances, pH value, hardness, etc. For recyclable water, the following requirements should be met:
1. The water quality issue of sewage: The water quality of sewage should not easily affect equipment corrosion, blockage, etc;
2. The indicators of its sewage should include requirements such as residual chlorine content, suspension toughness, number of coliform bacteria, BOD5, etc;
3. Its water should not give people an unpleasant feeling in terms of color, taste, and impurities.
At present, the industry wastewater in the market mainly includes: hospitals, pharmaceuticals, food, papermaking, domestic wastewater, bleaching and dyeing industry, animal husbandry, electroplating, painting, leather, etc.
