Embodiment 1
[0029] Such as figure 1 and figure 2 As shown, the treatment system for dispersed domestic sewage of the present invention is composed of a biological treatment unit and an ecological treatment unit. The biological treatment unit includes a two-compartment septic tank 12 and a hydrolysis acidification adjustment tank 1 . The ecological treatment unit is a reinforced artificial wetland 3 . The black water in the dispersed domestic sewage is treated by the two septic tanks 12 and the gray water flows into the hydrolytic acidification adjustment tank 1. After being homogenized, precipitated, and hydrolytic acidified, it is automatically controlled by the water inlet controller 2, and the siphon flows through the intensified tank in turn. The water distribution pipe 4 of the constructed wetland 3, the biological zeolite enhanced nitrification area 5, the denitrification area 6, the water collection area 7 and the water collection pipe 8 are finally discharged through the siphon d...
Embodiment 2
[0038] Such as figure 1 and figure 2 As shown, a treatment system for dispersed domestic sewage includes a septic tank 12 connected in series, a hydrolysis acidification adjustment tank 1 and an enhanced constructed wetland 3, and the enhanced constructed wetland 3 includes a water distribution pipe 4 and a biological zeolite enhanced nitrification area from top to bottom 5. The denitrification area 6 and the water collection area 7 are provided with a water collection pipe 8 in the water collection area, and the water collection pipe 8 is connected to the siphon drainage pipe 9 . The hydrolytic acidification regulating pool 1 and the reinforced constructed wetland 3 are connected through a water inlet controller 2, the water inlet controller 2 is a siphon water inlet system with a casing structure at the water inlet, and the casing structure includes an outer pipe 14 and an inner pipe, The inner pipe includes a horizontal section 10 of the inner pipe and a vertically arrang...
Embodiment 3
[0045] The difference with Embodiment 2 is that the distance between the highest position of the water inlet controller 2 and the height of the water inlet 11 of the inner pipe water inlet pipe is 25 cm, and the water inlet 11 of the inner pipe water inlet pipe and the bottom of the hydrolysis acidification regulating tank 1 The height difference is 80cm; the volume that can be accommodated in the hydrolysis acidification adjustment tank 1 between the water inlet 11 of the inner pipe inlet pipe and the highest position of the water inlet controller 2 is 1.3 times the pore volume of the biological zeolite enhanced nitrification zone 5. The matrix used in the biological zeolite enhanced nitrification zone 5 is zeolite, the filling thickness is 25cm, and the particle size of the zeolite is 3-7mm; the matrix used in the denitrification zone 6 is red brick slag, the particle size is 5-15mm, and the filling thickness is 60cm . Others are the same as embodiment 2.
