Abstract

The invention discloses a wool scouring wastewater treatment method. The method comprises the following steps: wool fat recycle and treatment; pH adjustment treatment, air flotation treatment, anaerobic biochemical treatment, aerobiotic biochemical treatment, hydrolysis acidification pool treatment, and entering of discharged water to a three-stage A / O (anoxic / oxic) pool; sludge treatment; discharging of sludge in a one-stage air flotation pool, a two-stage air flotation pool, the hydrolysis acidification pool and the A / O pool into a sludge concentration pool to perform concentration, flowingback of the liquid supernatant of the sludge concentration pool to an adjustment pool, dehydration of the sludge after concentration, and outward transport of mud cakes for disposition. The method provided by the invention can be used for effectively removing high-concentration organic matter in wool scouring wastewater.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for treating wool scouring wastewater. Background technique [0002] Wool scouring is an intermediate link of wool products. Since wool is collected in the original place with more impurities, the finished product must go through a washing process, and the washing wastewater generated is called wool scouring wastewater. Wool scouring wastewater is high-concentration organic wastewater discharged from the wool scouring production process, which contains sediment, lanolin, sheep manure, and a small amount of detergent and wool fiber. Wool washing wastewater is generally light yellow, smelly, and sticky. The main pollutant in the wastewater is lanolin, which has been emulsified and exists in the form of O / W (oil-in-water). High concentrations of CODcr and BOD5 in wastewater are also the main pollutants. is caused by lanolin. [0003] Since lanolin, the main pollu...
