Problems solved by technology
When using this device to treat high-concentration wastewater, it needs to consume a lot of water vapor, wasting energy; and the COD content of wastewater with a COD content of 91,800 mg / L was reduced to 3,200 mg / L after being treated by this equipment once. Although the COD content has dropped significantly, the Still not meeting emissions standards

Abstract
The invention relates to disposing and recycling equipment for high concentration organic wastewater, which comprises a raw water tank, an electric flocculation combined pool, an upflow anaerobic sludge bed, an A / O combined pool, a membrane biological reaction combined pool, an ultrafiltration device, a reverse osmosis device, a recycling water tank and a chemical dosing plant. Through the application of the technical scheme, on one hand, the disposing and recycling equipment for high concentration organic wastewater can fully remove high concentration organic matters in the waste water to reach the emission standard, and on the other hand, the disposing and recycling equipment can store the disposed waste water into the recycling water tank to be recycled, facilitates the environmental protection, and saves the water resource.
Description
technical field [0001] The invention relates to waste water treatment equipment, in particular to high-concentration organic waste water treatment and reuse equipment. Background technique [0002] High-concentration organic wastewater generally refers to wastewater with a chemical oxygen demand (COD) above 2000 mg / L discharged from papermaking, leather, printing and dyeing, chemical, pharmaceutical, and food industries. These wastewaters contain a large amount of carbohydrates, fats, proteins, cellulose and other organic matter. If they are discharged directly, they will cause serious pollution and pose a serious threat to human health. Organic pollutants, especially high-concentration organic pollutants, exist in water for a long time, migrate widely, and are harmful and difficult to deal with. The removal of high-concentration organic pollutants has always been an important research topic in the field of environmental protection. [0003] At present, there are generally...
