Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings and examples.

Referring to fig. 1 to 3, the self-cleaning intelligent toilet of the present invention is composed of a comprehensive sewage treatment apparatus and a toilet 01 (i.e., a convenient place), wherein the comprehensive sewage treatment apparatus is composed of a sewage pretreatment apparatus 02 and a sewage post-treatment apparatus 03.

The sewage post-treatment device 03 comprises a separator 031, a dehydrator 032, a processor 033, a negative oxygen ion generator 034, a purifier 035, a collector 036 and a reclaimed water reservoir 037, wherein the separator 031 separates clear liquid and sludge, the sludge contains about 25% of solids and needs to be further dehydrated, and the dehydration is completed in the dehydrator 0322. In the dehydrator, sludge containing about 25% of solids is dehydrated to about 55% of solids and then sent to a collector 036 for temporary storage.

The clear liquid from the separator enters a processor 033, mixes with the negative oxygen in the negative oxygen ion generator 034, generates an oxidation reaction in the processor, and generates clear liquid, turbid liquid and scum, and the clear liquid enters a purifier for further filtration to generate reclaimed water and concentrated liquid. The reclaimed water can be temporarily stored in the reclaimed water storage 7, and the concentrated solution can flow back to the separator to participate in the solid-liquid separation of the next round.

Turbid liquid generated in the processor can directly flow back to the separator to participate in a new round of solid-liquid separation; and the scum enters a dehydrator for dehydration, filtrate and sludge are generated through extrusion, and the filtrate flows back to the separator to participate in another round of solid-liquid separation.

Referring to fig. 4 to 6, the treater of the present invention includes two chambers, i.e., an aeration chamber 10 and a catalyst chamber 20, which are disposed in a single tank, wherein the aeration chamber 10 and the catalyst chamber 20 are disposed up and down and are communicated with each other by a conduit disposed at the top of the catalyst chamber.
