Development of biological treatment system for reduction of COD from textile wastewater
Wastewater from industrial plants such as textile, electroplating and petroleum refineries can contain various substances that tend to increase the chemical oxygen demand (COD) of the wastewater. Various local agencies have placed limits on the allowable levels of COD in industrial wastewater efflue...

| 總結: | Wastewater from industrial plants such as textile, electroplating and petroleum refineries can contain various substances that tend to increase the chemical oxygen demand (COD) of the wastewater. Various local agencies have placed limits on the allowable levels of COD in industrial wastewater effluent. It is desired to develop a process suitable for treating the wastewater to meet the regulatory limits. Various methods are available for COD reduction in industrial wastewater such as precipitation, incineration, chemical oxidation and biological oxidation. This project attempts to solve the high concentration of COD in industrial wastewater using bacteria. The organic matter that contributed to COD in the wastewater will be degraded by the bacteria under aerobic conditions using batch process. The wastewater will be supplemented with an agricultural liquid waste for bacterial growth and metabolism. This will ensure the continual presence of bacteria to carry out degradation of organic matter in the wastewater. |
