1. Experimental purpose:
Anaerobic digestion can be used to treat organic sludge and high-concentration soluble organic industrial wastewater (such as wastewater from alcohol plants and food processing plants). It is one of the m*n methods for treating wastewater and sludge. The
anaerobic digestion process is affected by factors such as pH, alkalinity, temperature, and load rate. The gas production is related to operating conditions and types of pollution. Before designing a digester, laboratory tests are generally required to determine the relevant design parameters. Therefore, it is important to master the anaerobic digestion experimental method.
Through this experiment, we hope to achieve the following goals:
1. Master the anaerobic digestion experimental method;
2. Understand the changes in pH, alkalinity, gas production, COD removal rate, and MLVSS during the anaerobic digestion process, and deepen our understanding of anaerobic digestion.
