Embodiment 1
[0046] Such as figure 1 with figure 2 As shown, a domestic sewage treatment system includes a sewage tank 10, an acid-base adjustment tank 20, an anaerobic decontamination tank 30, an aerobic decontamination tank 40, a backwash tank 50 and a water storage tank 60 connected in sequence through a water pipe 11; The sewage pool 10 is sequentially provided with a sewage flow velocity buffer assembly, an activated carbon layer 12, a mesoporous inorganic ceramic membrane filter layer 13, a microporous inorganic ceramic membrane filter layer 14 and a ceramic nanofiltration membrane filter layer 15 along the flow direction of the sewage. The water pipe 11 between the sewage pool 10 and the acid-base adjustment pool 20 is provided with a first one-way pipe 16 leading to the water inlet of the sewage pool 10, and the water outlet of the sewage pool 10 is provided with a turbidity sensor 17; The water outlet of the acid-base adjustment pool 20 is provided with a pH sensor 21, and betwe...
Embodiment 2
[0068] This embodiment is roughly the same as Embodiment 1, the difference is:
[0069] Both the lower buffer plate 19a and the upper buffer plate 19b are inclined toward the water inlet of the sewage tank 10, and the inclination angle is 60°.
[0070] The aperture of the membrane in the mesoporous inorganic ceramic membrane filter layer 13 is 40nm, the aperture of the membrane in the microporous inorganic ceramic membrane filter layer 14 is 20nm, and the aperture of the membrane in the ceramic nanofiltration membrane filter layer 15 is 10nm; The pore size of the ultrafiltration membrane 61 is 2nm.
[0071] The flocculant includes the following components by weight: 30 parts of polyacrylamide solution, 20 parts of polyaluminum chloride solution, 15 parts of BLINK magnetic powder, 2 parts of ferrous hydroxide, and 2 parts of diatomaceous earth.
[0072] The molecular weight of the polyacrylic acid solution is 3 million.
[0073] The deodorant comprises the following component...
Embodiment 3
