Ultrasonic standing wave radioactive wastewater treatment device

Abstract

The invention relates to an ultrasonic standing wave radioactive wastewater treatment device for collecting and treating suspended radioactive oxide particles in an acoustic standing wave field by an ultrasonic separating technology. The ultrasonic standing wave radioactive wastewater treatment device comprises an ultrasonic generator, ultrasonic transducers, a water tank, ultrasonic vibrating boards, a water feeding and discharging system, a power supply system and a rack; the ultrasonic transducers are fixedly sealed in the ultrasonic vibrating boards and below the bottom part of the water tank in a lattice form; the two ultrasonic vibrating boards on the left side surface and the right side surface of the water tank are relatively positioned in parallel and symmetrically distributed in the water tank; the two ultrasonic vibrating boards are dipped into the water tank; and a water inlet and a water outlet are respectively mounted in the rear sides of the front side and the rear side of the water tank and are arranged from top to bottom. The ultrasonic standing wave radioactive wastewater treatment device has the advantages that the technical staff is avoided working in an exposed high-risk environment, so that the personal safety is ensured; the radioactive substance in wastewater can be effectively removed, and thus secondary pollution is avoided; the technology is simple, the cost is decreased, the operation is easy, and a wide application prospect is brought.

Description

technical field [0001] The invention belongs to the field of waste water treatment and relates to an ultrasonic standing wave radioactive waste water treatment device. Background technique [0002] The Fukushima nuclear accident in Japan in March 2011 prompted the International Atomic Energy Agency to put forward higher requirements for nuclear energy safety. At the 19th International Conference on Nuclear Engineering (ICONE 19) held in Japan in 2011, developed countries led by the United States proposed to strengthen research on radioactive wastewater treatment devices, focusing on worldwide pollution caused by radioactive wastewater generated by nuclear power plants and other devices. Research on the problem. In order to make the radioactive radiation level of the environment lower than the standard value stipulated by the country (≤1Bq / L, that is, 1 Bq / L), it is necessary to carry out radioactive decontamination of the storage room and operation room of the device.
