Calculation And Design Of A Pig Farming Wastewater Treatment System With A Capacity Of 610 M3/Day

Abstract

Wastewater from processes in pig farming contains BOD, COD, TSS, TN, TP, and Coliforms at high levels, causing significant harm to the environment. The techonological methods applied to the treatment of swine wastewater are typically intricate and involve multiple stages of advanced processes. This thesis focuses on designing a wastewater treatment system for pig farming with a capacity of 610 m3/day, based on considering and evaluating the input concentrations of pig farming wastewater and the outlet water to meet the requirement of column A of QCVN 62-MT:2016/BTNMT. This thesis is divided into six parts. Chapter 1 provides a general introduction to the pig farming industry and common characteristics of wastewater composition. Chapter 2 presents an overview of treatment technologies, proposes two treatment technologies, and comparision between two proposals in term of advantages and disadvantages. Chapter 3 discusses the specific calculation parameters for each treatment unit. Chapter 4 covers the list of equipment used and Chapter 5 shows technical drawings of the treament units. Additionally, construction details of each treatment unit are illustrated in Chapter 6. References and appendices are placed at the end of the thesis.Hence, this thesis provides a comprehensive wastewater treatment system design for pig farming wastewater, which would be potential for application to treat wastewater sources with similar characteristics in the future.
