The available research was managed to monitor the physicochemical and microbiological features of treatment plants. The wastewater treatment herb sewage is a straight pollution input source for anthropogenic pollution. The sediment information ideas to an urban drainage trench as a secondary point pollution source while the organotins information highlights the presence of other spread sources, special to this material. wastewater re-use in urban has increased in many realms. The consequences of the study display that among the offered treatments, the best for asepsis and reducing microbial pollution of urban outlet effluent is that of the plus 0.25 weight percent Permanganate filter. Due to the amount of demand and need for the use of wastewater and circulated waters in agriculture, now most of wastewater treatment plants in the IRAN are designed and administered with the goal of reusing the wastewater produced in agriculture. Using wastewater increases the functioning of plants and does not have negative effects on the properties of the soil and its permeability. At the time in numerous cities of the IRAN the urban sewage and surface runoff which leave the cities, are used in farms downstream. The best option for the microbial disinfecting of the outlet wastewater in urban wastewater treatment plants among the treatments presented belonged to the plus 0.25 weight percent of potassium permanganate powder filter treatment. So that the percentage of the elimination of microbial pollution reached more than 99.99% Using this treatment in urban wastewater treatment plants can increase the microbial quality of wastewater to very high values, which can be utilized in farms, nutrition of groundwater resources, entrance to surface waters, Irrigating the green space, use in car-washes, etc.
