Use advice for data set
| When utilizing this dataset for Life Cycle Assessment, take into account the technological specificity and regional applicability of the data. Consider the local operating conditions, regulations, and efficiency parameters that are specific to the 17 WWTPs operating in China. Exclude any upstream or downstream processes that are not part of the Oxidation Ditch's processing, such as collection and distribution of wastewater or sludge handling which may be required to complete the LCA. The data should be adjusted to local context if applied outside of China, and users should ensure accurate matching for inputs and outputs relevant to the specific application of interest. Pay attention to temporal synchronization, ensuring that the data is consistent with the period during which an assessment is intended. |

Hierarchy level
|
|
| An oxidation ditch (OD) is a common biological treatment system used to treat organic matter and nitrogen in wastewater. An oxidation ditch is often a long, narrow channel filled with oxygen and covered with bottom sediment. Wastewater is injected into the oxidation ditch where microorganisms break down the organic material in the presence of oxygen. Nitrification and denitrification processes also occur in oxidation ditches, which help remove nitrogen from wastewater. Oxidation ditch is commonly used to treat wastewater from small to medium sized wastewater treatment plants and is an effective and low cost method of wastewater treatment. |

Technology description including background system
| In the oxidation ditch (OD) process, wastewater flows in long, narrow channels that are in full contact with oxygen, promoting degradation and oxidation of organic matter. Microorganisms decompose organic matter in the oxidation ditch, producing carbon dioxide and water. Nitrification and denitrification processes of nitrogen are also carried out in the oxidation ditch, which ultimately leads to the effective removal of organic matter and nitrogen from the wastewater and the purification and treatment of wastewater. |
