Abstract
The present invention provides an integrated system for treatment of biodegradable waste, including sewage sludge, forestry waste, food waste, agricultural waste, municipal waste, and the like. The integrated system comprises an anaerobic reactor, at least one aerobic reactor, a filtration device, and a desalinization device.
Claims37
A wastewater treatment system comprising:
- (a) an anaerobic reactor;
- (b) a first aerobic reactor;
- (c) a filtration device;
- (d) a desalinization device;
- (e) a first conduit connecting the anaerobic reactor to the first aerobic reactor;
- (f) a second conduit connecting the first aerobic reactor to the filtration device, wherein the second conduit comprises a second aerobic reactor to accept an effluent from the first aerobic reactor;
- and
- (g) a third conduit connecting the filtration device to the desalinization device.
5 more elements
A method of treating wastewater, the method comprising the steps of
- (a) treating for a first period, a first mixture comprising wastewater under anaerobic conditions in an anaerobic reactor to form an anaerobic reactor effluent;
- (b) treating for a second period, the anaerobic reactor effluent under aerobic conditions in a first aerobic reactor to form a first aerobic reactor effluent;
- (c) treating for a third period, the first aerobic reactor effluent under aerobic conditions in a second aerobic reactor to form a second aerobic reactor effluent;
- (d) passing the second aerobic reactor effluent through a filtration device to form a filtration device effluent;
- and
- (d) passing the filtration device effluent through a desalinization device to form a desalinization device effluent.
