Environmental Sustainability Assessment by Investigating the Performance of urban Water Treatment Plant

Non-commercial and peaceful application of valid and advanced international technologies compatible with human and environmental health, for the complete and scientific treatment of toxic contaminants imposed on clean water resources, for optimal use of the ultimate blessings of the absolute Creator (GOD) of the world, and the elimination of human self-made problems has a particular importance. For this purpose, in the present study, a descriptive and cross-sectional study was performed on the Hamadan wastewater treatment plant operating with an activated sludge treatment system from December to February 2018-2019. In the evaluation of the treatment plant, five quality parameters of inlet and outlet wastewater were measured twice a day and in total six times per month. Then, while analyzing the results by SPSS software, graphs of these parameters were plotted with Excel software. The results showed a relative decrease of 96.27%, 20.20%, 96.11%, 94.23% and 7.16% of TSS, COD, BOD, NTU and pH parameters, respectively. As a result, the treated wastewater, due to its very low acidic properties, can be used in the electric power industry. Also, despite the permissible short-term use of contaminated wastewater in agriculture and the environment, further international validation of their application is essential for the sensitivity of the risk to the increasingly catastrophic and irreparable carcinogenicity of incomplete wastewater treatment.
