- چکیده:
- چکیده انگلیسی: One of the main problems in the quality control of rivers is the high control cost imposed upon pollutant units. The cooperative policy approach in the treatment process between two or more pollutant units is a new and economic perspective in the environmental management of catchment basins. Origins of large amounts pollutants which require a high cost to control pollution are trying to start partnerships with smaller units in establishing joint refineries in order to reduce their own and the whole system's costs. In this study, considering the one way direction of the river's water, the Streeter – Phelps equations were used to simulate the river. The Ant Colony Optimization was used as an efficiency model in order to acquire the best scenario of cooperation based on the maximum elimination of pollution and reduction of treatment costs without straying from the river's quality standards. Also the ratio – trade system was used for commercial purposes. After this the cost of the depleting units was split evenly between them using the cooperative game theory. The efficiency of the model was evaluated by qualitative and quantitative analysis of the Zarjub River in Gilan province of Iran. Three main scenarios were taken to mind for cooperative trading to take place. Carrying out the trade – partnership model could play positively large role in sufficing the quality the control of river water.

- چکیده:
- چکیده انگلیسی: Due to increasing solid waste generation and their significant impacts on human health, environmental assessment of the management and disposal methods become more and more important. There are various disposal methods which are the combinations that originate from a wide range of solid waste management systems. In this study, municipal waste of Tehran (which totals to 7507.5 tons/day) is assessed according to five suggested scenarios. Life cycle assessment method was applied to compare the selected scenarios to select the most efficient solid waste management scenario in Tehran. Hence, the Eco-indicator 99 is utilized as the impact assessment method. The effects are evaluated in three categories including; effects on human health (organic substances, inorganic substances, climate change, ionizing radiation and ozone layer depletion), ecosystem quality (ecotoxic emissions, the combination of acidification & eutrophication and double coating) and resources (extraction of minerals and the fossil fuels). According to the results, scenario one leads to the most damage to the environment especially on the human health, whereas scenario four has the most positive impacts compared to the others. However, scenarios two and three are unsuitable due to their negative effects on human health. Although, scenario five shows positive results on the resources but again it has negative impacts on human health and ecosystem quality. Moreover, the most appropriate strategy in terms of land usage and energy consumption, again is scenario four (landfilling plus recycling and composting) is chosen as the most proper strategy.

- چکیده:
- چکیده انگلیسی: The primary objective of desalination research is the development of a way to produce fresh water at lower cost. The present study investigated two freshwater production methods of Reverse Osmosis (RO) and Multi-Effect Humidification (MEH) (artificial distillation), and analyzed them from an economic standpoint, and subsequently pointed out the important and effective factors in decreasing saltwater desalination expenditure for each one of the mentioned units. Different aspects of these units were investigated as well. However, all the prices are assumed with the current condition and expenses in Sistan Baluchestan province, Iran. The results from economic analyses, obtained employing COMFAR III, showed that, in regions where locals have access to local grid, application of RO unit has no economic justification, while MEH units, powered by solar energy, are more economic in remote regions receiving adequate solar irradiation. However, the water produced by RO can be purchased at 0.02 $/lit, and by solar MEH unit (Respect to introduced characterization), at 0.032 $/lit. Although, the sensitive analysis of IRRs’ variation in proportion to three factors namely sales income, fixed capital expenditure and operational expenditure were conducted.
