An integrated device for source-separated urine treatment using hypergravity technology

Abstract

The invention provides an integrated device for source-separated urine treatment using supergravity technology, which belongs to the technical field of sewage treatment. The device includes a high-gravity circulation treatment system, a gas feeding system, a liquid feeding system, an instrument circuit control system, a medicament adding system, a tail gas treatment system, a liquid storage tank, a precipitation reactor and a solid filter. The separated urine and air from the source to be treated enter the high-gravity circulation treatment system at the same time for multi-stage blow-off; after the blow-off, the effluent is discharged into the precipitation reactor for the precipitation and crystallization reaction of struvite; after the precipitation reaction, the effluent enters the solid filter for filtration and collection to obtain bird Fecal sedimentation; after filtration, the effluent and ozone gas enter the high-gravity circulation treatment system at the same time, and the reaction tail gas enters the tail gas treatment device. The device realizes the effective removal of ammonia nitrogen and organic pollutants in source-separated urine, and at the same time recovers phosphorus, which reduces operating costs and reaction time, and is convenient for system optimization and energy saving.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated device for source-separated urine treatment using supergravity technology. Background technique [0002] Urine is a high-concentration liquid rich in nitrogen and phosphorus, which has dual characteristics of pollution and resources. Nitrogen is of great significance to the normal operation of life activities, and if a large amount of ammonia nitrogen discharged into the water body exceeds the self-purification saturation of the water body, it will cause eutrophication of the water body; phosphorus, as a non-renewable resource, is also gradually decreasing. Urine only accounts for less than 1% of domestic sewage, but it contributes 80% and 50% of nitrogen and phosphorus in urban domestic sewage. Therefore, the separate collection and treatment of urine, the removal of harmful substances and the recovery of nutrients are of great significance for the effect...

AI Technical Summary

Problems solved by technology

The removal of harmful elements and the recovery of beneficial elements can be achieved simultaneously by coupling these three treatment technologies. However, due to the large number of processes, the common composite treatment technology has the disadvantages of complex operation and low efficiency.
