Improper handling of domestic wastewater can have a number of negative impacts to the environment, hence the importance of good management and treatment of the same. The present study aims to evaluate the efficiency of the use of microorganisms for the treatment of domestic sewage in a treatment plant wastewater in the north of Bogota. The PTARD under study is a Redfox type plant with a throughput of 0.5 LPS which treats water by activated sludge system. The study was conducted in three major phases: diagnostic phase, implementation phase and evaluation phase. In the diagnostic phase, from a control sample a bacterial sorting through Gram staining was performed, and in turn became the identification of fungi by microscopy with dichotomous key. Followed this phase was conducted to monitor the concentration of pollutant load in the activated sludge system operating and monitoring environmental factors, which allowed to establish the necessary conditions for development of microorganisms conditions. And then physicochemical tests of control and monitor the wastewater were performed in order to determine the initial conditions and pollutant loads containing wastewater, also, its intermediate and final conditions will be monitored during the implementation of the microorganisms in the reactor.
When comparing the initial and final concentrations of the physicochemical parameters COD, BOD, and TSS and based on the implementation of previously identified aerobic microorganisms in the system of activated sludge treatment; It found that the use of these microorganisms allowed the removal of a 79.8% organic loading in the reactor, contributing to a proper functioning of the PTARD and in turn fulfilling the legal environmental regulations in force. He was able to identify the bacteria that perform the removal process are the GRAM and fungi are working together Fusarium, Penicillium and Aspergillus. |
