摘要：

The performance of a post-treatment pond for treating swine wastewater from an UASB reactor was evaluated. The system was assembled with an anaerobic baffle reactor (RAC), followed by an UASB reactor (UASB) on a real scale, and a post- treatment pond on a demonstration scale. The following parameters were analyzed: pH, biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), volatile suspended solids (VSS), ammonia nitrogen (N-am.), total phosphorus (Pt), total coliforms (CT) and Escherichia coliE coli.). The post- treatment lagoons contributed efficiently to remove nutrients, organic matter and solids, providing an effluent quality for agricultural reuse or discharge into a body of water.
