加裝一套真空污水泵站，節(jié)省的水電費和運營成本遠大于壽命周期增加的設(shè)備費用。
Areas with scarce water resource
s;
(b) Transportation toilet systems such as ships, trains and long-distance buses and public toilet systems in remote areas;
The toilet drainage system in the basement with small flow of people;
Infectious diseases hospital drainage system, closed collection to avoid the spread of germs;
