IV. Water consumption of solidifying workshop
The process water consumption in the solidifying workshop is 4.1 m
3 /d, or
1353 m
3 /a as calculated based on 330 days. The process water in the solidifying
workshop comes from the percolate treatment plant.
V. Domestic sewage
The domestic sewage discharge is 950.4 m
3 /a (2.88 m
3 /d) as calculated based on
0.1 m
3
/person day of domestic water consumption and 20% of loss rate. The newly
produced domestic sewage in the hazardous waste landfill, after pretreated by the
septic tank, is conveyed to the secondary sewage treatment works in the new area
for centralized treatment.
The output and discharge of wastewater pollution sources are listed in
Table 5.122.
