Included activities starts

The activity begins with the receipt of wastewater at the gate of the treatment facility and does not include the collection and transportation of wastewater to treatment plants.

Included activities ends

The activity ends with wastewater being treated and specific wastes being discharged into the environment. Expenditures for wastewater treatment at waste treatment plants and related infrastructure at the plant are included. Discharges from any sludge digestion, biogas generation and utilization (note the specific wastewater composition) are also included.

Description

This dataset represents the treatment of wastewater generated by general transformation activities. The average COD content of domestic sewage in Baicheng City, Jilin Province is 0.3393 kg/m3, and the BOD is 0.1585 kg/m3. The wastewater treatment process shares in this region are: CASS 45.67%, Carrousel oxidation ditch 37.46%, BIOLAK 16.87%.

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.
