Reabilitation of a wastewater treatment plant – possible environment impact

Abstract

Romania, has declared, by the Governmental Decision nr.352/2005, all its territory as a sensitive area. This implies that, for all urban agglomerations larger than 10.000 population equivalent waste water treatment plants (WWTP) with nutrient removal must be built or upgraded. This paper presents the results regarding the possible environmental impacts expected from the project for construction of waste water treatment plant in the City of Vaslui, with main focus on surface water. This research study includes assessment methodology, project description regarding the rehabilitation and extension of the Vaslui waste water treatment plant, data related to water resources, impact assessment on water and appropriate mitigation measures. The assessment of the impacts has been performed for the construction and operational phase of the wastewater treatment plant. The construction phase was subdivided into several phases, while in the operational phase the impacts are analyzed following the line for treatment of the wastewater and effluent production, the line for sludge production and drying process, sludge disposal in safety conditions considering the provisions of 86/278/EEC Directive and the line for biogas utilization.

Age structure and body size of two Tibetan toad (Bufo tibetanus) populations from different elevations in China

“…This technique enables researchers to collect information on demographic parameters (e.g., age, growth rate, and longevity) of the population in a relatively short time without killing the animals. This method has been used successfully in a variety of species of anurans, including species from temperate, subtropical, and tropical regions (temperate: López et al., 2017 ; Ma, Tong, & Lu, 2009 ; Zhang et al., 2013 , 2020 ; Subtropical: Brum et al., 2019 ; Liao & Lu, 2010a ; Zhou et al., 2010 ; tropical: Khonsue et al., 2000 ; Stanescu, 2015 ).…”
