Filed:
Aug 6, 1984
Appl. No.:
6/637727
Inventors:

International Classification:
C02F 1102
US Classification:
210609
Abstract:
According to an embodiment thereof, the method comprises using a pair of reaction vessels, sequentially, to treat the sludge. Both vessels are pressurized, and the first thereof has an aerator for aerating the sludge, and receives sulfuric acid and chlorine thereinto through a port. A dewatering device is provided upstream of the first vessel, and the outlet of the first vessel is coupled to an inlet of the second vessel through another dewatering device. The second vessel defines a final-treatment chamber in which the sludge is exposed to ozone, air and lime. The treatment method, then, comprises the steps namely: introducing the sludge into the first vessel and oxidizing and depressing the pH of the sludge so introduced, and recycling the sludge in the first vessel over a given period of time. Thereafter the sludge is dewatered and conducted to the second vessel wherein it is exposed to air, ozone and lime, as aforesaid, and discharged after a like period of time. The solid and liquid constituents are separated from the discharged sludge, and the latter is returned to the first vessel.
