In this paper,the bottom pot water in distilleries was treated with the Sequencing Soil System(SSS),some factors which affect the removal of COD such as the concenteation of wastewater,the pH value of solution and the amount of wastewater were studied.

Purified purple non-sulfur bacteria 01S strain was separated and fostered from activated sludge of brewery wastewater and used to treat high concentrated organic brewery wastewater.

Brewery wastewater from Sichuan Quanxing Brewery was treated by anaerobic-aerobic technique combined with effective microbes.

Caproic acid bacteria species separated from quality aged pit mud were cultured in 30 % spent wash of Luzhou-flavor Daqu liquor.

The bottom pot water in distilleries mainly containes the following substances: ①The pollutant by the leakage of fermented grains,distiller's grains and raw materials in bottom pot;②The pollutant of high boiling point acids,esters,sugar and ethanol;③The pollutant produced by the steaming of ending liquor in bottom pot etc.

New method of treating distillery wastewater——3-process removing“SS”;
