Application example 1
The sewage treatment plant of Changji in Xinjiang can treat 5 million tons of sewage per day and generate 10 tons of domestic sludge with absolute dry sludge. The method comprises the steps of sending sludge with water content of 80% into a dilution conditioning tank on site, adding water to dilute the sludge until the water content is 93%, and then adding ferric trichloride solution and lime into the conditioning tank.
