Abstract
The invention belongs to the technical field of sewage treatment, and in particular relates to a united device for treating high-concentration organic wastewater. The united device comprises an adjusting tank, a wastewater lifting pump, a flowmeter, an ABGR reactor, an acidification hydrolysis anaerobic reactor, a circulation backflow pump, an MBR bioreactor, a self-priming pump, a catalytic ozonation tower, a clean water tank, a backwash pump and an ozone generator. The united device has the characteristics of small space occupation, low foundation expense and compact design, compared with the prior art, the total investment can be reduced by about 30%, in operation, the air oxygen conversion and utilization rate of the device is high, the oxygen transfer rate is not less than 50%, the air of a biochemical part of the device has a strong turbulent shearing function, formed sludge granules are fine, the microorganism density is large, the biochemical reaction degree is high, and the amount of residual sludge is small; in management, the united device is good in impact resistance of biochemical environment, stable to operate, small in artificial interference operation and high in automatic degree, and the standard can be met at one time.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a combined device for treating high-concentration organic wastewater. Background technique [0002] High-concentration organic wastewater has the characteristics of high pollutant concentration (COD as high as thousands to tens of thousands), complex components, high chroma, high toxicity, wide sources, different properties, and difficult treatment, which is very harmful to the environment. . The current treatment methods mainly include: physical and chemical methods, chemical methods and biochemical methods, both of which have defects such as limited removal effect or high operating costs; biochemical methods can greatly reduce investment and operating costs, but for containing For high-concentration wastewater with a certain amount of toxic pollutants, whether anaerobic biochemical treatment or aerobic biochemical treatment is used, the influent concentrat...
