Included activities starts

This activity starts with the reception of wastewater at the gate of the treatment facility. It does not include the collection and transportation of wastewater to the treatment plant

Included activities ends

The activity concludes with the treatment of wastewater and the discharge of specific wastes into the environment. It includes expenditures for wastewater treatment at waste treatment plants and the relevant infrastructure of the plant. Any emissions from sludge digestion, biogas generation, and utilization (note the specific wastewater constituents) are also included.

Description

The dataset represents the treatment of wastewater generated by ordinary transformation activities. In the domestic wastewater of Guiyang City, Guizhou Province, the average COD content is 0.0625 kg/m3, and the BOD is 0.1219 kg/m3. The proportions of wastewater treatment processes in this area are as follows: Modified A²/O accounts for 41.89%, SBR accounts for 36.3%, Modified SBR accounts for 10.81%, Oxidation ditch accounts for 7.77%, Secondary biochemical treatment accounts for 2.33%, and Other methods account for 0.91%.

Process Description

Domestic wastewater\" is the 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 ordinary transformation activities. Generally treated as waste (non-recyclable), it requires further processing. Domestic wastewater can be modeled at two levels: treatment activities and market activities. The former refers to specific technologies/Hybrid technology for treating this waste, while the latter represents mixed processing. Two modeling methods are available for users to choose flexibly. When specific process assumptions are made for wastewater treatment, specific technology treatment activities can be selected. The collection and transportation of wastewater are considered in the use of sewer infrastructure in their respective market activities; the conveyance of wastewater through the sewer grid leads to losses before the wastewater enters the wastewater treatment plant. Direct emissions due to these losses are considered in the market activities. Losses are region-specific, so users are encouraged to check the regional modeling assumptions.
