Description
This dataset represents the average domestic wastewater treatment situation in the Northwestern region of China, which includes Shaanxi, Gansu, Qinghai, Ningxia, and Xinjiang. The dataset is calculated based on the 'List of Nationally Centralized Wastewater Treatment Facilities' issued by the Ministry of Ecology and Environment of the People's Republic of China for this region.
The dataset includes expenditures for wastewater treatment at waste treatment plants as well as related infrastructure of the plants. Emissions from any sludge digestion, biogas generation and utilization (noting specific wastewater components) are also included.
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.
