الملخص

Hydrogen sulfide (H 2 S) is a naturally occurring, highly toxic gas that is formed from the decomposition of sulfur compounds. At low concentrations, H 2 S is an irritant for the eyes, respiratory and gastrointestinal tract. At higher H 2 S concentrations, it produces neurological impairment with dizziness, headache, and loss of consciousness. Mortality was reported to reach 6 percent following exposure to elevated concentrations. H 2 S is generated in different industrial processes. In wastewater collection and treatment plants, H 2 S is a common source of concrete and metal corrosion that has resulted in huge economic loss. In this project, the factors leading to the generation of H 2 S in wastewater has been studied. Different parameters were measured from Al-Saad wastewater treatment plant, UAE. Wastewater samples were collected for measurement of chemical properties affecting H 2 S generation in the laboratory. Significant parameters were identified to be temperature of wastewater, humidity, total sulfur, and wastewater depth, using correlation analysis with corresponding H 2 S concentration. Statistical equations formed from this regression analysis was used to estimate the H 2 S concentration in headspace. A neural network model with an R-sq value of 0.9 was developed to predict H 2 S emission at different wastewater unit operations. Studying the generation of H 2 S in wastewater would in effect help alleviate the maintenance costs of wastewater treatment systems.
