An Introduction to the Vacuum Separate Collection and Transportation System of Excreta, Perishable Domestic Waste and Domestic Wastewater

摘要

Vacuum Separate Collection and Transportation System of excreta, perishable domestic waste and domestic wastewater (VSCATS) is very useful in saving water, protecting the environment as well in utilize water more efficiently. Using this system, only 1 liter of water is needed in flushing the bedpan each time, so that freshwater can be saved. After bio-chemical treatment, the domestic waster reclaimed can be reused and the excreta and the perishable domestic waste can be used as organic fertilizer, so that a waste recycle and reuse ecological system is formed. This paper gives a brief introduction to the technological processes, working principles, the relevant technologies and the designing parameters.
