【 摘 要 】

The inactivation of Opisthorchis felineus eggs in the wastewater was demonstrated. The wastewater samples were taken at the bio-filter outlet of district wastewater treatment plant of settlement "Airport" of rural settlement "Mirnenskoe" of Tomsk district of Tomsk region. The UV irradiation of wastewater samples was performed by the combined exposure of UV excilamps at 282 and 222 nm. There was less than 15% of the initial count of Opisthorchis felineus eggs in the wastewater after the UV treatment at the total surface dose of 25 mJ/cm2. At the same time, 85% of the eggs lost the shell integrity and destroyed. It is proposed to use UV irradiation by excilamps to wastewater deworming on wastewater treatment plants of small capacity up to 200 m3/day.
