Integrated device for performing source separation urine treatment by applying supergravity technology

Abstract

The invention provides an integrated device for performing source separation urine treatment by applying a supergravity technology, and belongs to the technical field of sewage treatment. The device comprises a supergravity circulating treatment system, a gas feeding system, a liquid feeding system, an instrument circuit control system, an agent adding system, a tail gas treatment system, a liquidstorage tank, a precipitation reactor and a solid filter. To-be-treated source separation urine and air simultaneously enter the supergravity circulating treatment system to be subjected to multi-stage air stripping; after air stripping, the effluent is discharged into the precipitation reactor for struvite precipitation and crystallization reaction; after precipitation reaction, the effluent enters the solid filter to be filtered, and struvite precipitate is collected; and the filtered effluent and ozone gas simultaneously enter the supergravity circulating treatment system again, and reaction tail gas enters the tail gas treatment device. The device realizes effective removal of ammonia nitrogen and organic pollutants in source separation urine, recovers the phosphorus element, reducesthe operation cost and the reaction time, and is convenient for system optimization, energy conservation and consumption reduction.

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.
