Description
technical field [0001] The invention relates to industrial production waste water treatment equipment, in particular to a device for treating high-concentration chemical fiber waste water by anaerobic (UASB) method. Background technique [0002] The wastewater produced in the production of polyester fiber has large fluctuations in water quality, with COD as high as 2600mg / L, BOD as high as 1000mg / L, and SS as high as 500mg / L, obviously belonging to high-concentration organic wastewater. Organic wastewater is easily degraded by microorganisms, so it is more reasonable to adopt biological treatment methods. Or use full aerobic biological treatment, or use anaerobic + aerobic biological treatment. From a technical point of view, anaerobic treatment technology has little energy requirements, higher volume load than aerobic load, less land occupation, less demand for nutrients, high organic matter removal per unit reactor volume, and less pollution generated by anaerobic methods...
