Determining Sources of Unpleasant Odour resulting from Runoff in the Imam Khomeini Airport

About Project

Currently, in ​​Imam Khomeini Airport, and especially in the surrounding areas of Islamshahr, Baharestan Counties and south of these areas to the airport, sniffing of unpleasant odour is considered as one of the serious problems, so that national and international travellers to the country and its inhabitants faced a drastic problem in terms of smells of unpleasant and harsh odour. Generally, the unpleasant odour seemed to be due to the three main reasons of wastewater, waste, and slaughterhouses and stockbreeding. In order to solve the problem, it is necessary to identify and monitor the sources of unpleasant odour in accordance with scientific methods, moreover, the contribution of each source should be determined with respect to the weather conditions including direction and diffusion intensity. Hence, studies on determining the sources of unpleasant odour have been performed with special attention to surface runoff in the Imam Khomeini Airport with emphasizing on contaminated waterways of wastewater and waste discharges. Modelling of odour dispersion was the main goal of these studies.

Actual services:

• Equipping a field laboratory to measure odor on site using an adsorbent
• Equipping the field laboratory to perform a quantitative and qualitative monitoring program, including portable multimeter and portable turbidity meter for on-site measurement and sampling containers for stabilizing and transferring samples in a standard condition.
• Site selection and layout for installation of an anemometer in the area to calibrate the air pollution model
• Performing 4 period of surveys to identify the sources unpleasant odor in the study area including wastewater and waste disposal sites, contaminated surface water sources, livestock farms, slaughterhouses, pollutant factories and …
• Measuring ammonia, hydrogen sulfide and methane in the air of Tehran-Qom highway and in the study area by round the clock
• Site selection of stations to measure water and wastewater quality parameters
• Modeling air pollution (odor) in the study area by AERMOD
• Identification of odor sources and determining their shares to producing unpleasant odor
• Zoning of contaminated areas and specification of relevant methods for omitting odors and presenting management plans of water quality, wastewater, poultry and livestock farms in the study area
