Embodiment 1
[0031] A process for treating rural domestic sewage, which mainly includes the following steps:
[0032] Step 1: Collect rural domestic sewage in a sewage tank, and pre-treat the domestic sewage in the sewage tank;
[0033] Step 2: Perform aerobic biochemical treatment on the domestic sewage after pretreatment in Step 1;
[0034] Step 3: Perform the collaborative treatment of micro-nano bubbles and biofilm carrier on the domestic sewage after the aerobic biochemical process in Step 2.
[0035] In this embodiment, concentrating rural domestic sewage in a sewage tank (not shown in the figure) can facilitate centralized treatment of rural domestic sewage and prevent rural domestic sewage from being discharged everywhere and polluting the environment or soil. In the sewage tank, domestic sewage can be filtered and precipitated to remove impurities such as sediment, clay, organic matter and mechanical impurities in the sewage to ensure the efficiency and quality of subsequent sewage treatm...
Embodiment 2
[0037] The sewage treatment equipment includes a plurality of sewage treatment barrels 1, each of which is provided with an air inlet pipe 2, a first water inlet pipe 3, and a first drain pipe 4, the air inlet pipe 2, the first water inlet pipe 3 Both ends of the first drain pipe 4 and the first drain pipe 4 extend out of the sewage treatment bucket 1, and the bottom side wall of the sewage treatment bucket 1 is connected with a sewage pipe 5. The second inlet pipe 6 and the second outlet pipe 7 are respectively above and below the plurality of sewage treatment barrels 1, one end of the second inlet pipe 6 is closed, the other end of the second inlet pipe 6 extends into the sewage source, and the second outlet One end of the water pipe 7 is closed, and the other end of the second water outlet pipe 7 extends into the collection tank. The second water inlet pipe 6 communicates with the first water inlet pipe 3 through a third water inlet pipe 8, and the second drainage pipe commu...
Embodiment 3
[0051] The wetland treatment equipment includes several wetland modules 19, which are connected in a regular quadrilateral or regular hexagonal manner to form the wetland treatment equipment. The side walls of the wetland module 19 are respectively provided with a water inlet 20 and a water outlet 21. The water inlet 20 and the water outlet 21 are respectively located on opposite sides of the wetland module 19, and the water inlet 20 and the water outlet 21 are alternately arranged in up and down positions. The water outlet of the second water outlet pipe 7 extends into the water inlet 20 of the wetland module 19; the wetland module 19 includes a soil layer 22, a biofilm-coated porous filler layer 23, and a porous ceramic layer 24 from top to bottom. The surface of the wetland module 19 is provided with a micro-nano bubble input inlet 25, and the micro-nano bubble input inlet 25 is sequentially connected with a micro-nano bubble generator 26 and a fan 27; the depth of the micro-...
