THE PROJECT OF THE TECHNOLOGICAL LINE OF THE
ELECTRONIC-BEAM DRAINS DISINFECTION IN THE INFECTED
HOSPITALS’ DIVISIONS AND TUBERCULAR CENTRES

The purpose of the project was to create the
electrophysical facility for the environmental protection
from contamination by drains of the infected hospitals’
divisions and tubercular centres and prevention of open
water reservoirs.
In this project two main problems are solved:
Development of the economically approved methods of
the radiative disinfection of contaminated drains;
development of the inexpensive compact facility for the
electron-beam disinfection of small volume drains
(up to 25 cubic meters daily).
During the development work the authors have
proceeded from the well-known fact, that only radiation
disinfection methods, realized on the modern
electrophysical engineering, can supply the solution of
the indicated problem (1). The principles and real
disinfection radiation facilities of the polluted waste
water are used widely and practically in all
industrialized countries of the world. It is precisely
determined, that the disinfection radiation technologies
have no the alternative both on the efficiency, and on
technological perfection. It is well known that,
simultaneously with the neutralization of the
microorganisms, in these technologies other processes
are also realized - the destruction of the organic
contamination and surface-active substances, silt and
various inclusions coagulate actively.
The radiation facilities are characterized by high
profitability and ecological safety. Cost of processing at
the radiation facilities depends directly on their
capacity. For receiving high economic parameters it is
expedient to create the high-capacity facility. Therefore
the original cost of such type facilities is rather high and
not always is accessible for municipal services of small
cities or separate medical establishments. For Ukraine
and Russia it is the only reason of low distribution of
the disinfection radiation facilities in practical use.
Especially it is important for small health service
objects. And just here the disinfection problem has
acquired a very acute character. Because of the
infectious diseases amount increasing, including
socially dangerous, tuberculosis and other heavy lungs
diseases, the amount of activators of these diseases in
the open water reservoirs is increased. Taking into
consideration the long period of their existence in the
open water reservoirs, the disinfection problem of drains
becomes acute and very actual.
Analysis of the situation, with due regard for the
objective economic aspects, shows, that the justified
way for the problem resolving is the creation of the
radiative technologies and facilities adapted for using by
municipal services, hospitals and tubercular centres. It is
determined, that typical volume of the infected drains of
the hospital divisions and regional tubercular centres
does not exceed 20-24 cubic meters. To use the
expensive facility for these purposes is economically
inexpedient.
The solution of this problem is the creation of the
indicated capacity facility, which cost would not exceed
the cost of the similar facility of thermal sterilization
(autoclaving). It excludes the possibility of using typical
industrial accelerators (even of the direct operation) due
to their excessively high cost for our case, and
accordingly the technologies of sterilization created for
such type facilities.
Using the previous experience of the sea stuff
waste radiation disinfection (2), the drain
decontamination was carried out by the low energy
electrons for the solution of this problem - only
0.4 - 0.5 MeV, and for the technology improvement the
combined technique was used.
The scheme of facility is shown in Fig. 1. The
technological line is designed for two- staged process of
the disinfection realization. At first, waste water passes
the first stage of the disinfection - processing by the air
with the large contents of ozone. At the second stage -
the water is irradiated with electrons. At the both stages
of the process the electrophysical means are used: at the
first - ozone generator, at the second - electron
accelerator. For the effective irradiation of the whole
water volume, it is foamed on all stages, by this the
developed surface and qualitative processing of water
with electrons of low energy is provided.
The offered disinfection scheme is based on the
effects of the bactericidal and bacteriostatic ozone and
electron influence taking into consideration the
appropriate requests to their application. These requests
are realized rather simply by using the modern charged
particle accelerators, which are inexpensive and simple
in operation.
The total profitability of the facility and its low
cost is ensured by the original construction of the
electron accelerator. For this purpose the construction

based on the high-capacity X-ray tube with excluded
target unit is used.
Such type tube supplying from the voltage
source of 400-500 kV with the capacity up to 100 kWt
and pumped out to the vacuum of 10 mm of the mercury
column by the electric-discharge pump of the NORD
type, allows to receive the electron beams with the
energy of 400 KeV and the radiation capacity up to
2.5 kWt. So, it makes possible to treat not less than
20 000 kg of the polluted drains by the doze 5 kGr per
day (practical lethality of the tubercle bacillus).
The technological scheme of the radiation part of
the facility is shown in Fig. 1. (Typical kinematic
schemes and units of the starting filtration and
brightening of waste water are omitted). Infected,
previously filtered drains come to the accumulator (1),
and further to the camera of pre-processing (5). Here
during the disinfection process the bubbling of the
liquid by the ozonized air takes place. For this purpose
the electrical ozone generator (3) is provided. Passing
through this generator the air is enriched by this highly
active component and is used for the bubbling (2). On
the liquid surface in the accumulator (5) the layer of
foam is formed, which is mixed all the time. The liquid
in the foam state is processed. Further the foam
surpluses, which run out the camera boundaries (5) as a
thin layer, flow on the working table surface (6), where
they are irradiated with electrons from the accelerator
(7). Disinfected foam flows into the accumulator (8) and
is poured out into the standard sewerage system.
The biological protection of the process is
reached by the location of the accelerator, ozonizer and
entrance of the infected liquid accumulator in the
isolated camera (11) with the appropriate thickness of
the protective walls. All subsidiary devices – the
sources of the high-voltage supply (9, 10) and power
monitoring equipment are placed outside this camera.
During designing the experimental works were
executed and the authors' experience in solving the
similar problem for the sea stuff waste processing was
used. The technological regulations of the disinfection
process are developed.

In Table 1 some experimental data obtained on
the disinfection efficiency of the polluted drains with
various parameters of dozes are shown. Knowing the
value of starting contamination, it is possible to select
the necessary modes of disinfection, to use optimum
possibilities and resources of the facility, to prevent the
excessive current consumption.
