Harmless and resourceful dry sanitary ware and method for solid-liquid separation

Abstract

The invention relates to a harmless reclamation dry type sanitary unit and a solid-liquid separation method which are capable of efficiently and durably achieving solid-liquid separation. The method includes three steps of firstly, subjecting feces and liquid mixture in a treatment device to treatment with dedicated powder and then extracting liquid supernatant formed after flocculation is precipitated through a filter composed of a filter screen to a dehydration device; secondly, heating the liquid supernatant in vacuum in the dehydration device to partially become steam which enters a condenser to be condensed as water; thirdly, discharging the remaining liquid supernatant of high concentration into the treatment device for being mixed, collecting the solids after flocculation is precipitated through a collection device and packaging. The harmless reclamation dry type sanitary unit is specially used for achieving the solid-liquid separation method.

Description

technical field [0001] The invention relates to a harmless and resourceful dry sanitary ware, and also relates to a solid-liquid separation method. Background technique [0002] Harmless and resource-based dry sanitary ware needs to deal with human excrement. Generally, human excrement contains both solid feces and liquid urine. Therefore, solid-liquid separation must be considered in the design of sanitary ware. The method of solid-liquid separation in early stage sanitary ware is the filtering method (referring to patent document CN103417158A) that realizes by a filter screen, develops later and realizes through special-purpose solid-liquid separator (referring to patent document CN103462549A), and described solid-liquid separator includes The outer layer of the cylindrical filter element is wrapped with polytetrafluoroethylene material. There is a hollow channel in the middle of the filter element that communicates with the high-pressure air source so that the air can be ...

Problems solved by technology

But the effect of this method is not good, because after the first use of the solid-liquid separator, many small holes on the polytetrafluoroethylene material are blocked by jelly, and it is difficult to dredge these small holes even if the high-pressure gas is blown in reverse. , so that the strike shortly after use
