摘要
Low volume of produced wastewater and specific regional, environmental and economic condition in small communities determines the methods of treatment of sewage in such communities including shorelines of Bandar Abbas, Bushehr, Imam Khomeini Harbor and Chabahar Harbor. Ineffective methods of treating and sewing wastewater in aforesaid terminals as well as limitations of methods of wastewater treatment such as high level of underground waters doubled the necessity of considering alternative methods. In this paper, investigation of current conditions was performed through field observations and data collection regarding wastewater production in terminals and determination of qualitative specifications using sampling and carrying out pH, TSS, COD, BOD and temperature tests from inlet to outlet of available sewage system of abovementioned terminals and comparison with environmental organization standards corresponding to wastewater sewage and it was found out that conditions of available systems of wastewater treatment are not suitable. In this regard, modifying solutions for the sake of improving performance of systems of wastewater treatment of terminals is presented in this research. Finally, for wastewater treatment system of Bandar Abbas terminal, if there is no limitation for allocating lands, it is recommended to use artificial canebrake system with underground flow.
