EVALUATION AND CHOICE PROCESS MUNICIPAL WASTEWATER TREATMENT WITH CONSTRATION APPROACH AND OPTIMASITON WITH METHOD AHP(CASE STUDY: SHOUSHTAR CITY)

Application software and mathematical models in wastewater treatment processes combined with technical know-how precious time is to be treatmen wastwater, in order to stabilize the organic matter in large and small communities done intermediate good water and sanitation can be considered the value is added and the resulting solid material reuse it to produce effluent standard and to strengthen the underground aquifers done, Methods: as part of this research using the analytic hierarchy process (AHP) and the work developed by the Expert Choice software relying on the experts compared the different processes were, Results: of the five selected processes with weights WETLAND (0.399) and weight POND (0.351) BIOLAC with (0.108) and weight SBR process (0.085) and CAS weight (0.057) WETLAND option or Wetland with subsurface due weight should mention (0.399) has been chosen. Conclusions: in another part of the city of Shoushtar research using case study and review laboratory results ,Confirmed that to design and build a wastewater treatment plant wastewater is important both quantitative and qualitative parameters and the financial comparison and evaluation processes of the study verified a first method (AHP) as a result, natural and semi-natural method because the process of being cheap and relatively quick return on investment with good efficiency Been selected.
