Juice acid, fatty acid, mucoprotein.Waste water is first acidified to PH=5-6 with dilution heat of sulfuric acid, is stirred 5- by waste water using distribution acidification
10 minutes, black fluid shape precipitating will be generated in waste water.Most of BILE PIGMENTS, mucoprotein and fatty acid first precipitate, with stirring
During mixing, most sticky contaminant precipitating is sticked to poking bar precipitation；Acid is carried out with dilution heat of sulfuric acid carrying out second
Change to PH=2-3, cotton-shaped miscellaneous cholic acid will be generated and precipitated, after standing, sour water layer is limpid bright.And if using disposable continuous acid
Change, the sour water layer of waste water acidification is slightly cloudy, cannot thoroughly collect sediment.Into treated excessively, waste water removes most fat
Acid, mucoprotein and miscellaneous cholic acid, the BOD content being effectively reduced in waste water.To use as feed after the precipitating drying of miscellaneous cholic acid
Bile acid efficiently utilizes the miscellaneous cholic acid in waste water.On upper layer, sour water layer inhales rainbow to sedimentation basin, and milk of lime is added and is adjusted
PH is greater than 10, reacts milk of lime and fatty acid remaining in sour water layer, organic acid and sulfuric acid etc. and generates fatty acid calcium, organic acid
The precipitating such as calcium and calcium sulfate further removes remaining fatty acid, organic acid and sulfuric acid etc. in sour water layer.After treatment clear
Clear micro- yellow waste water meets the condition of waste water station processing, can directly be handled by waste water station；And white depositions are fat
The precipitatings such as sour calcium, calcium of organic acid and calcium sulfate can bracket handled by solid slag without polluting and wasting.
