Vacuum collection and vacuum treatment process of fecal sewage and equipment thereof

The invention discloses a fecal sewage collection and treatment process and a device thereof. As the urbanization process of China is accelerated, the treating pressure of urban fecal sewage is greater. The fecal sewage collection and treatment process adopts two vacuum tanks to carry out the vacuum collection and the vacuum treatment of fecal sewage, the two vacuum tanks are not only vacuum collection tanks but also vacuum treatment tanks, and are mutually switched and respectively in the different working states, thereby leading the vacuum collection and the treatment to be continuous; the vacuum tank which is in the vacuum collection state continuously collects the fecal sewage and simultaneously recovers the condensation heat of the other vacuum tank when distilled water is generated by the vacuum treatment, thereby being used for the preheating and the pre-degasification of the fecal sewage, further saving energy, reducing operated process time and lowering operation cost; the distilled water is carried out the treatment by a physical absorbent and then used for flushing a toilet, cleaning and the vacuum tanks, thereby achieving the self-sufficiency, having no need of an external water source for supplement and saving the freshwater resources.
