Among the figure, 1. sewage inlet; 2. tensimeter; 3. control handle; 4. screen filter; 5. minor valve; 6. cavity; 7. plant; 8. pedosphere; 9. reuse water outlet; 10. little gravel bed; 11. large gravel bed; 12. piston; 13. solid residue passage; 14. methane-generating pit; 15. reuse water outlet valve; 16. reuse water water reservoir; 17. settling bath;
In addition, a place is WWT state (piston 10 closing conditions); The b place is slagging-off state (piston 10 open modes).
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Like Fig. 1; The reuse water recycle apparatus structure of the utility model is; Be included on the pipeline between sewage inlet 1 and the reuse water outlet 9 and be disposed with tensimeter 2, settling bath 17, screen filter 4, minor valve 5, drowned flow artificial wet land and reuse water water reservoir 16
The base plate opening of settling bath 17 and solid residue passage 13 UNICOMs; Solid residue passage 13 is communicated with methane-generating pit 14 or collecting tank; Solid residue passage 13 waists are provided with cavity 6, are provided with piston 12 in the solid residue passage 13, and the control handle 3 of piston 12 upwards stretches out outside the settling bath 17;
Drowned flow artificial wet land comprises three layers; Be large gravel bed 11, little gravel bed 10, pedosphere 8 from top to bottom successively; The pipeline of minor valve 5 outlets puts in the large gravel bed 11; Successively through infiltration pass little gravel bed 10, pedosphere 8 backs are communicated with reuse water water reservoir 16, reuse water water reservoir 16 exports 9 with reuse water and is communicated with, reuse water exports 9 and is provided with reuse water outlet valve 15.
