Autopurificarea (autoepurarea) apelor uzate menajere şi industriale tratate conform tehnologiilor de epurare expertizate şi aprobate în Republica Moldova [Articol]

Abstract

The self-treatment capacity of domestic wastewater, treated by treatment technologies approved in the republic at discharge into the environment is higher than 0.2 with biological treatment from medium to high, and in some technologies at the exit from the system with a value of 0.07, biological treatability being lacking, and at 0.19 the biological treatability is low. In some industrial wastewater treatment technologies, at discharge into the environment, waste- water self-treatment at the outlet of the treatment system is from medium to low (AC of 0.12-0.2). Thus, it is necessary to comply with regulatory requirements regarding the conditions of discharge of wastewater into water bodies when implementing wastewater treatment technologies.
