This study presents some data about the water pollution status of Bahlui river in Iasi town area (two control sections) mainly due to domestic and urban wastewater treatment activities, considering especially some quality indicators (i.e. nitrogen-based nutrients, total phosphorus and sum organics content) evaluated for 2009-2010. The Bahlui water classification by European standards in Iasi town area corresponds to ‘medium’ (WQI = 53.893 - 64.345). The real water pollution state of Bahlui river (Iasi town area) is estimated by the global pollution index (I*GP), and corresponds to values of 2.80-2.929 (Valea Lupului-Iasi control section), and 3.030-3.196 (Holboca control section, i.e. downstream of Dancu wastewater treatment plant). These values are indicating an aquatic environment modified by domestic and urban wastewater treatment activities, generating discomfort effects, or producing stress against aquatic life forms. These data are recommending application of hydro-ameliorative/remediation actions, and permanent control of Bahlui watercourse quality in all existing control sections.

Whole Life Cycle

Effect and benefits of a product or service could be analyzed and evaluated by life cycle assessment during the whole life cycle. Urban sewage treatment plants could improve and control urban water pollution escalating, but it also had certain harm to environment. Effect and benefits of urban wastewater treatment plant A and B were analyzed and evaluated, 13 factors were selected, and comprehensive benefits were researched quantificationally using the method of analytic hierarchy process. It found that urban wastewater treatment plant A who applied A/O process had better benefits than urban wastewater treatment plant B who applied BIOLAK process.
