PROPOSED TECHNOLOGY OF WASTEWATER TREATMENT IS RADIATED IN VIET - SINH GENERAL HOSPITAL

Abstract

Wastewater treatment at the hospital has been studied at many works, national and international topics. However, for waste water from the process of radioactive contamination in the tumor department is not mentioned. This type of waste water flow although not large, but there are many potential risks to environmental problems. The content of the article is a proposed technology for radioactive waste treatment through the separation of waste and treatment by disassembly based on the classification of the International Atomic Energy Agency (IAEA).

The drug used at the Viet - Sinh hospital's oncology department is Floodoxyglucose, commonly referred to as 18F-FDG, which is a radioactive medicine used in cancer treatment. Based on the composition and properties of 18F-FDG, the calculated disintegration time of the compound was 120 minutes, combined with the volume of waste source in the tumor department was 3.6 m³ / day to propose handling measures. Design of 2 treatment tanks with capacity of 5 m³ and 108 m³ respectively, was built in the basement of Viet - Sinh General Hospital. Structure of two tanks made of reinforced concrete, the inside and bottom of the tank is covered with 1.5mm thick sheet of lead. For the 108 m³ tank, divided into 04 compartments, each compartment has a water retention time of 5-7 days to ensure that the total radioactive content in waste water has been disposed completely before being connected to the common wastewater treatment system of the hospital.
