A nuclear chemical decontamination wastewater treatment process and system

Abstract

The invention discloses a nucleation decontamination wastewater treatment technology and system.The system manly comprises a coagulating sedimentation integrated reactor, a filter, a multi-medium efficient adsorption tank, an ion exchange softener, a precise filter, an ultrafiltration membrane, a reverse osmosis membrane, an ion exchange softening protector and the like.The nucleation decontamination wastewater treatment technology of the system includes the following steps that nucleation decontamination wastewater is collected, precipitated and primarily separated through an in-situ coagulating sedimentation reactor, separated nucleation decontamination wastewater mixed liquid enters the filter for further solid-liquid separation, a filter outlet solution is sequentially input into the multi-medium efficient adsorption tank and the ion exchange softener, obtained filter liquid passes the precise filter and then is pumped into the ultrafiltration membrane and the reverse osmosis membrane for treatment, and then the filter liquid is discharged through the ion exchange softening protector.The method can solve the nucleation decontamination wastewater treatment problem in a modularization mode, nuclide wastewater and decontamination wastewater can be deeply and efficiently treated under different load conditions at the same time, and water outflow indexes can meet the water supplement reuse and up-to-standard discharge requirements in the decontamination process.

Description

technical field [0001] The invention relates to a method applied to the advanced treatment of nucleation and decontamination wastewater, in particular to a process and system that can satisfy large flow and high load and can simultaneously treat nuclides and decontamination wastewater in depth. Background technique [0002] Decontamination refers to measures to disinfect and eliminate contamination of personnel, equipment, materials, fortifications, roads, etc. contaminated with toxic agents, biological warfare agents, and radioactive substances. The purpose of decontamination is to avoid or reduce damage to the infected troops, so that the contaminated equipment and materials can be used normally. Chemical defense decontamination is an important task for the chemical defense decontamination team to implement personnel decontamination operations. [0003] In the process of anti-chemical decontamination, chlorinated oxidizing disinfectants are mostly used as the main chemica...
