Abstract

The invention discloses a hospital radioactive wastewater decay tank system. The system comprises a water inlet system, a first decay tank, a second decay tank and a water outlet system which are sequentially connected through cast iron pipes, the water outlet system is respectively connected with the second decay tank and the clean water tank, a detector is further arranged on the water outlet system, and tap water in the clean water tank is used for diluting secondary decay liquid treated by the second decay tank; the detector is used for detecting the standard liquid discharged from the water outlet system; meanwhile, the invention further provides a treatment method for radioactive wastewater decay. Rapid coagulation and removal of radionuclides are achieved by adding a chemical treatment agent. The hospital radioactive wastewater conveyed into the decay tank is stored and filtered, after chemical treatment agents are added for treatment, the hospital radioactive wastewater sequentially enters the decay tank to become decay liquid, the decay liquid reaches a water outlet system, reaches the standard through detection and is discharged to a drainage channel from a water outlet control valve, the treatment time is shortened, and meanwhile the complexity of the decay tank system is reduced; and the space is saved.

Description

technical field [0001] The invention relates to the technical field of radioactive waste water treatment, in particular to a hospital radioactive waste water decay pool system and a treatment method for the radioactive waste water decay. Background technique [0002] Hospitals mostly use radioisotopes when diagnosing and treating tumor or cancer patients. Patients produce excrement after injection or taking radioisotope drugs, and a large amount of radioactive waste water will be generated when the excrement is washed and discharged. This has also become a hospital The main source of radioactive wastewater; in addition, hospital laboratory sewage, radioactive protective clothing and washing water of medical equipment and medical equipment, drug preparation, and dumping of excess doses of isotope drugs will all produce radioactive wastewater; Wastewater, to shorten the decay cycle, may mix and discharge part of the hospital's domestic sewage and radioactive wastewater; theref...
