The process method for carrying out nuclear biochemical waste liquid by using the nuclear biochemical waste liquid treatment system comprises the following steps:
after nuclear biochemical accidents happen, first, a supersaturated tri-combination two-decontamination agent is used for decontaminating on-site polluted personnel and the environment when rescue personnel perform on-site treatment, and generated decontaminating wastewater is collected in the wastewater tank 1. When the nuclear biochemical decontamination waste liquid treatment system works, waste liquid firstly enters a system pipeline through the suction of the submersible pump 2, and then sequentially enters the booster pump 4, the No. I electric valve 6, the bag filter 7, the tubular micro-filter 8, the security filter 12, the primary high-pressure pump 13, the high-pressure nano-filter 14, the secondary high-pressure pump 15, the high-pressure reverse osmosis 16 and the selective adsorption device 17. The bag filter 7 is responsible for intercepting large particles in the waste liquid; the tubular micro-filtration 8 is used for filtering undissolved suspended state three-in-two in the waste liquid to prevent the liquid from blocking a subsequent membrane treatment unit; the cartridge filter 12 is the last barrier of the membrane processing unit for filtering various impurities above 5 microns; because the trinary-binary sodium bisulfite solution has very strong oxidability, the pH value of the waste liquid needs to be adjusted before the waste liquid enters the high-pressure nanofiltration 14, the pH value of the collected waste liquid is transmitted to the control system 21 by the pH sensor 3 in a signal of 4-20 mA, the control system 21 adopts fuzzy control to accurately adjust the dosage of the dosing device 11 in real time, and the sodium bisulfite solution is added into a pipeline to ensure that the pH value of the waste liquid is neutral; the waste liquid enters a high-pressure nanofiltration 14, then monovalent ions and divalent and more ions are separated and inactivated biological toxin agents are intercepted, the ions in high valence state continuously enter an ultrahigh-pressure reverse osmosis 19 under the action of a three-stage high-pressure pump 18, and enter a concentrated water tank 20 after being concentrated in high power, and part of fresh water returns to the raw water tank 1; the monovalent ions in the waste liquid continue to enter the high-pressure reverse osmosis 16, the waste liquid is further filtered and purified under the action of the second-stage high-pressure pump 15, most of nuclide ions flow back to the cartridge filter 12 along with the concentrated water and are circularly filtered, part of escaped nuclide ions enter the selective adsorption device 17 along with the fresh water, and finally, the nuclide ions are firmly fixed on the surface of the adsorption material under the action of zero-valent iron, and the rest of conventional ions are discharged along with the fresh water. The whole working process is controlled in a centralized way by the control system 21, the control system 21 adjusts the frequency of the first-stage high-pressure pump 13, the second-stage high-pressure pump 15 and the third-stage high-pressure pump 18 and the opening of the electric valve in real time according to signals fed back by the pressure sensor, the flow sensor and the conductivity sensor, and the pressure and the flow of the high-pressure nanofiltration 14, the high-pressure reverse osmosis 16 and the ultrahigh-pressure reverse osmosis 19 are accurately controlled, so that the highest filtration efficiency is achieved, and the standard discharge of the final fresh water is ensured.
The nuclear biochemical decontamination waste liquid treatment system adopts a pretreatment process taking tubular microfiltration as a main body, does not add polymer flocculation materials, and can effectively prevent the pollution of a subsequent membrane treatment unit. In addition, the outer membrane treatment unit adopts a membrane separation process combining high-pressure nanofiltration, high-pressure reverse osmosis and ultrahigh-pressure reverse osmosis to treat various ions in the waste liquid in batches, so that the treatment difficulty is reduced, and both purification and concentration are achieved. And finally, a selective adsorption material loaded with nano zero-valent iron is adopted, so that the residual nuclide ions in the waste liquid can be selectively adsorbed, and the nuclide ions are firmly and firmly fixed on the surface of the adsorption material by means of the chemical characteristics of the zero-valent iron, so that the desorption phenomenon is avoided. The treatment process adopting the device has high filtration efficiency, high concentration multiple and wide application range, can be suitable for purifying various high-solid matters and high-salt waste liquid, and completely meets the treatment requirement of nuclear biochemical decontamination waste liquid.
