Resumen
The main objective of this study was to evaluate the efficiency of the porcine water treatment system by means of stabilization ponds in the Minimal security agricultural colony of Acacias, Department of Meta, which was developed from an initial diagnosis by means of In Situ Monitoring (Dissolved oxygen (OD), conductivity, flow rate, pH, water temperature (° C) and sedimentable solids (Ssed.); Ex situ monitoring (chemical oxygen demand (COD), biochemical oxygen demand (BOD5) (SST) and microbiological parameters (thermotolerant coliforms, fecal enterococci and Salmonella sp.)) during the dry season (February and March) and rainy season (April and May). The system was identified as three series lagoons, one anoxic (No.1) and two aerobic (No. 2 and 3). The study allowed us to determine that the system managed a temperature range between 23 ° C and 33 ° C; In terms of pH, O.D. And conductivity variations were 6.2 and 8.89 units; 2.76 and 23.43 ppm and 989 and 1567 μS / cm, respectively. The maximum daily inlet flow of the system was 3 l / s with values of 134 ml / l for sedimentable solids, this factor added to the time of operation generates the filling of the lagoons. The system has been able to adapt to the conditions in terms of efficiency of the system, since the highest average removal efficiency was in dry season with data of BOD5 97.68% COD 90.98% and SST 82.17%, compared to the rainy season, where the percentages recorded were 96.94%, 89.60% and 79.4%, respectively; In terms of the microbiological parameters evaluated, they were absent in the system effluent in the dry season. The following factors of incidence in the efficiency of the treatment system: (i) dilution of the concentrations of BOD5, COD and SST in the affluent by high flow of the rain; (ii) use of Efficient Microorganisms (EM) in the production system and directly in lagoon No.1. Finally, we formulated conceptual strategies for the optimization of the processes, such as the screening facility, desander, by-pass, baffles and segregation of the rainwater of the porous effluent to treat, which have to be executed by the Institution.
