Problems solved by technology

[0002] The existing treatment of radioactive sewage in hospitals requires multiple sewage storage pools to store sewage in turn to ensure that the sewage is stored in each storage pool for a sufficient time so that the radioactive substances in the sewage decay to meet the discharge requirements. The half-attenuation period is long, therefore, the sewage needs to be stored in the sewage storage tank for a long time, so a sewage tank with sufficient capacity is needed. The sewage tanks in the prior art are constructed by geotechnical engineering and built side by side underground, so the sewage tanks occupy a large area , and the area of ​​the hospital is limited, the sewage pool that needs to occupy a large building area restricts the work of the hospital to carry out radiotherapy, and it is not easy to set up maintenance facilities for the pool constructed by geotechnical engineering, so it is easy to occur due to lack of maintenance. Leakage accidents, since the leaked radioactive sewage is difficult to deal with after a leak occurs

Embodiment 1

[0011] Embodiment 1: as figure 1 Shown, hospital radioactive sewage treatment device of the present invention is realized in this way, comprises the septic tank 1 that has radiation-proof protective layer 101, sludge tank 2, the decay tower 4 that outer surface is wrapped with radiation-proof protective layer 3, The decay tower 4 is provided with several closed sewage pools 5 from bottom to top, the top of the decay tower 4 is an exhaust port 6, the septic tank 1, the sludge tank 2 and the decay tower 4 are all arranged in the basement A, and the septic tank 1. A protective wall B is installed around the sludge tank 2 and the decay tower 4. The sewage tank 2 is connected to the exhaust port 6 through the exhaust pipe 7. The septic tank 1 is provided with a grille 8 to separate the septic tank 1. into a solid settlement area 102 and a clean water area 103, and the clean water area 103 passes through a pumping mechanism 9 with a radiation-proof protective structure (including a ...

Embodiment 2

[0013] Embodiment 2: as figure 2 As shown, this embodiment is based on Embodiment 1, and there are two sets of pumping mechanisms 9 with protective structures and first solenoid valves 10 . In this way, when the first solenoid valve 10 of one set of pumping mechanisms 9 needs to be maintained or repaired and disassembled, the other set of pumping mechanisms 9 can be activated, so as not to affect the treatment of radioactive sewage.

[0014] The two ports of the first electromagnetic valve 10 are provided with a first valve 15 , and the inlet and outlet of the first electromagnetic valve 10 are connected with a flushing pipeline 17 with a second valve 16 . When the first battery valve 10 needs to be disassembled, first close the first valve 15, open the second valve 16, then introduce flushing fluid into the first battery valve 10 through the flushing pipeline 17, and flush the radioactive substances in the first solenoid valve 10 Clean, flushing fluid can be introduced into...

Abstract

A hospital radioactive sewage treatment device relates to the technical field of sewage treatment, in particular to a hospital radioactive sewage treatment technology, and is characterized by comprising a septic tank, a sludge tank and a decay tower, the outer surface of the decay tower is coated with a protective layer, the decay tower is provided with a plurality of closed sewage tanks from bottom to top, and the top of the decay tower is provided with an exhaust port. The sewage pools are communicated with the exhaust port through an exhaust pipe, the septic tank is provided with a grating, the clear water area is communicated with the sewage pools through a pumping mechanism with a protective structure, first electromagnetic valves are arranged between the pumping mechanism and the sewage pools, and the discharge port of each sewage pool is communicated with the sludge pool through a blow-off pipeline with a first valve. Compared with the prior art, the sewage tank has the advantages that the sewage tank with the large enough volume can be arranged, meanwhile, the occupied area is small, maintenance facilities are convenient to arrange, and leakage is prevented through daily maintenance.
