Description
This dataset represents the treatment of wastewater generated from common conversion activities. The average COD content in domestic wastewater in Shanghai is 0.2355 kg/m³, and BOD is 0.0884 kg/m³. The proportions of wastewater treatment processes in this region are: secondary biochemical treatment 42.33%, activated sludge process 34.01%, A²/O 11.67%, A/O 5.95%, oxidation ditch 3.65%, and others 2.4%.
Process Description
"Domestic wastewater" is wastewater generated from residential sources. It originates from a wide range of residential, industrial, and commercial activities. In the HIQ database, the treatment options for this wastewater include: wastewater treatment plants.
Domestic wastewater is produced by common transformation activities. It is generally considered waste (non-recyclable) and requires further treatment.
Domestic wastewater can be modeled at two levels: treatment activities and market activities. The former refers to specific technologies or technology mixes for treating this waste, while the latter represents a mixture of treatment processes. Two modeling approaches are available for users to choose flexibly. When making specific process assumptions about wastewater treatment, users may select specific technology treatment activities. Wastewater collection and transport are considered in their respective market activities involving sewer infrastructure; the conveyance of wastewater through sewer grates before entering the treatment plant leads to losses. Direct emissions resulting from these losses are accounted for within the market activities. These losses are region-specific, so users are encouraged to review the regional modeling assumptions.

Geography comment
The mean annual temperature (MAT) of the region is 16.9543672657561 °C, and the mean annual precipitation (MAP) is 1416.78299031388 mm/year. In the wastewater treatment plant, 0% of the influent is lost due to pond evaporation, and 0.144% of the water is removed from the site through sludge treatment.
