Abstract

The invention relates to a device and a method for recycling treatment of amino containing waste water and belongs to the field of alcohol-amine desulfurization liquid purification. The recycling treatment device mainly comprises a recycling tank, a pressurizing pump and a nano-filtration membrane assembly, wherein the recycling tank, the pressurizing pump and the nano-filtration membrane assembly are sequentially connected through pipelines and valves, a concentrated water outlet of the nano-filtration membrane assembly is connected to the recycling tank through a pipeline, and a yield water outlet of the nano-filtration membrane assembly is connected to a waste water treatment system through a pipeline. Planer nano-filtration membranes are used for filtering, are convenient to assemble and easy to wash and exchange, the waste water circulation cross section area is large, blockage cannot easily occur, and different number of membranes can be assembled according to waste water properties and waste water quantity. Cross-flow filtration is adopted in the invention, part of amine fluid can be refluxed, the pollution of waste water to the nano-filtration membranes can be reduced, and the concentrating rate can be improved.

Description

technical field [0001] The invention relates to a recovery and treatment device and method for amine-containing waste water, in particular to a recovery device and method for sweetened amine liquid waste water, and belongs to the field of purification of sweetened amine liquid. The nanofiltration membrane filtration method is used to treat and recover the amine in the amine-containing wastewater, which avoids the pollution of the amine-containing wastewater to the environment and the impact on the downstream advanced wastewater treatment device. Background technique [0002] Alcohol amine desulfurization and decarburization is the most important method in the gas purification process of oil and gas processing. At present, in the field of sweetening amine liquid purification, it is common to use filtration and ion exchange methods to remove impurities in amine liquid. The use of ion exchange resins The treatment of recycled wastewater is also a difficult problem to solve. Wh...
