Abstract:
A special vacuum excrement collection and sewage discharge treatment system comprises a waste box (4). A sewage filtering and washing apparatus (10) is mounted on one side of the waste box (4). The sewage filtering and washing apparatus (10) comprises at least a filter screen supporting cylinder (101). A filter drum (102) is accommodated inside an inner cavity of the filter screen supporting cylinder (101), and the filter drum (102) is hollow. Active carbon is disposed inside a sandwich layer formed by the inner wall surface and the outer wall surface of the filter drum (102) to form an active carbon filter layer (103). Multiple filtration pores are formed in the inner wall surface and the outer wall surface of the filter drum (102) to form a filter screen. One end of a flow guide pipe (105) provided with spray holes (104) is disposed in the inner cavity of the filter drum (102) and is used as a flushing water outlet, and the other end of the flow guide pipe (105) is disposed outside the waste box (4) and is used as a flushing water inlet. The inner cavity of the filter drum (102) is in communication with a treated-drainage water port (106) disposed on the waste box (4). An opening (107) in communication with the inner cavity of the waste box (4) is further formed in the filter screen supporting cylinder (101) and is used as an inlet for sewage to be treated and an outlet for waste after treatment. After the sewage filtering and washing apparatus (10) is additionally disposed on an existing waste box (4), liquid and solid are separated on the apparatus, the sustained use time of the system is increased, and normal use of an excrement collection system in various states can be ensured.
