Description
This dataset represents the treatment of wastewater generated by common transformation activities. In Jiaozuo, Henan Province, the average COD content in domestic sewage is 0.2416 kg/m3, and the BOD is 0.0978 kg/m3. The wastewater treatment process shares in this region are: Carrousel oxidation ditch 51.55%; Orbal oxidation ditch 27.18%; secondary biochemical treatment 5.51%; MBR 3.93%; oxidation ditch 3.93%; others 7.9%.
Process Description
"Domestic wastewater" is wastewater generated from residential sources. It comes from a wide range of residential, industrial and commercial activities. In the HIQ database, the treatment options for this wastewater include: wastewater treatment plant.
Domestic wastewater is produced from common conversion activities. Generally treated as waste (not recyclable) and requiring further processing.
Domestic wastewater can be modeled at two levels: treatment activities and market activities. The former refers to the specific technology/mix of technologies used to treat that waste, while the latter represents mixed processing. Two modeling approaches provide the user with the flexibility to select technology-specific treatment activities when specific process assumptions are made for wastewater treatment.
The collection and transportation of wastewater consider the use of sewer infrastructure in their respective market activities; transporting wastewater through sewer grids results in losses before the wastewater enters the wastewater treatment plant. Direct emissions due to these losses are taken into account in market activities. Losses are region-specific, so users are encouraged to check regional modeling assumptions.
