A nuclear waste water treatment system comprises an initial filtering device, an intermediate filtering device and a post filtering device which are sequentially connected, wherein the initial filtering device comprises a waste water tank and a first filter, and the waste water tank is connected with the first filter through a lifting pump; the intermediate filtering device comprises a second filter, a first-stage multi-media filter and a security filter, wherein the second filter is respectively communicated with the first filter and the first-stage multi-media filter, and the first-stage multi-media filter is connected with the security filter; the post filtering device comprises a secondary multi-medium filter and a reverse osmosis film device, wherein the reverse osmosis film device isconnected with the security filter through a high-pressure pump; and the reverse osmosis film device is connected with the secondary multi-medium filter. The nuclear waste water treatment system caneffectively remove silt, rust or other large particle impurities in nuclear radiation waste water, efficiently adsorbs radioactive elements in the nuclear radiation waste water, and obtains the effectof non-radioactive water purification.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a nuclear wastewater treatment system. Background technique [0002] my country's radioactive wastewater is divided into high, medium, low and weak radioactive wastewater according to the level of radioactivity. The sources of wastewater include nuclear power plant wastewater, uranium mining wastewater, spent fuel reprocessing wastewater, and wastewater generated by hospitals, scientific research and other units. The wastewater produced by uranium mining and smelting mainly contains nuclides including U, Ra and trace amounts of Po and Pb210, which belongs to low-radioactive wastewater. Nuclear power plant waste water mainly includes main equipment and auxiliary equipment evacuation water, reactor discharge water, second circuit waste water, cleaning waste liquid, ion exchange device regeneration waste water and special washing water, etc. It is mainly medium and low ...
