BIOLOGICAL PRETREATMENT OF WASTEWATER ENTERING IN GLINA-BUCHAREST TREATMENT PLANT, A PROBLEM STILL TO BE SOLVED
Abstract
Glina Station is a project for the treatment of wastewater from the sewerage of Bucharest. The sewerage of the entire city has always flowed into the Dambovita River. Currently, only partially Stage I is carried out, through which the mechanical treatment of about 60% of the city's wastewater is carried out. The paper presents a solution for biological pretreatment of wastewater to validate the use of ultraviolet waves for biological disinfection but also for the treatment of specific non-synthetic pollutants from water. It is estimated the impact of pollutant emissions on water resources in the area. The effects of the specific measures that water users must apply to achieve the environmental status, modeling emissions of organic substances, priority substances and specific pollutants are identified. Natural background levels in these transported bodies of water (water, sediment and suspended solid materials), priority substances (heavy metals: Cd, Ni, Pb and Hg) and specific non-synthetic pollutants (Ca, Zn, Cu, Cr, phenols, and others) depending on the allowable base values were determined. The technical solution for biological water pretreatment is presented briefly. In the third tank the homogeneous mixture is made. Next, the physical-chemical reactor and the installation for introducing the dosing and preparation reagents until the final water purification are realized. The main advantages of the pre-treatment of wastewater and selection of the most suitable substances are mentioned also.
