DETAILED DESCRIPTION

[0024] See Figure 1-Figure 3 As shown, the technical solution adopted in this specific embodiment is: a sewage treatment device for village and town water ecological circulation, including a sedimentation and filtration tank 1 and an aeration purification tank 7, a partition 13 is provided in the middle of the sedimentation and filtration tank 1, the sedimentation and filtration tank 1 on the left side of the partition 13 is a first sedimentation zone 2, a water trough 14 is provided at the bottom of the partition 13, an interception net 15 is provided on the water trough 14, a sewage inlet pipe 11 is provided on the upper side wall of the first sedimentation zone 2 and connected to the external sewage tank, a filter assembly 4 is provided in the middle of the sedimentation and filtration tank 1 on the left side of the partition 13, a filter area 5 is above the filter assembly 4, and a second sedimentation zone 3 is below the filter area 5, a filtered water outlet pipe 12 is provided on the outer side wall of the filter area 5, and the plane of the filtered water outlet pipe 12 is lower than the plane of the sewage inlet pipe 11;

[0025] A filtered water inlet pipe 71 is provided on the upper side wall of the aeration purification tank 7, and the filtered water inlet pipe 71 is connected to the filtered water outlet pipe 12 via a first pumping pump 6. A clean water outlet pipe 72 is provided on the bottom side wall of the aeration purification tank 7, and the clean water outlet pipe 72 is connected to an external clean water tank via a second pumping pump 10; an aeration component 9 is provided at the bottom of the aeration purification tank 7, and a stirring component 8 for accelerating aeration efficiency is provided inside the aeration purification tank 7.

[0026] In which, the filter assembly 4 includes a first filter screen 41, a second filter screen 42 arranged above the first filter screen 41 and a filter medium 43 arranged between the first filter screen 41 and the second filter screen 42. The mesh number of the interception net 15 is larger than the mesh number of the first filter screen 41, the mesh number of the first filter screen 41 is smaller than the mesh number of the second filter screen 42, and the particle size of the filter medium 43 is larger than the sieve holes of the first filter screen 41 and the second filter screen 42.

[0027] The filter medium 43 is a lightweight, elastic suspended filter material with a density less than that of water. The lightweight suspended filter material is buoyant, forming a relatively dense filter layer. Specifically, as the water level rises, the suspended filter material is blocked by the second filter screen and no longer rises. As the liquid level rises, the filter material is further compacted, achieving a better filtration effect.

[0028] The filter medium 43 is at least one of pumice, peat soil, perlite, quartz sand, ceramsite, zeolite or activated carbon, and the type or thickness of the filter medium is set according to the rainwater treatment requirements.

[0029] The stirring assembly 8 includes a servo motor 81 installed on the top of the aeration purification tank 7. The output end of the servo motor 81 extends downward into the aeration purification tank 7 and is fixedly connected to a stirring rod 82. The outer wall of the stirring rod 82 is provided with a plurality of stirring blades 83.

[0030] The aeration assembly 9 includes an aerator 91 installed at the outer bottom of the aeration purification tank 7. The air outlet of the aerator 91 extends upward into the aeration purification tank 7 and is connected to an air supply pipe 92. The air supply pipe 92 is connected to a plurality of aeration plates 93.

[0031] A first inspection cover 21 is provided at the upper end of the first settling area 2 , a first sewage pipe 22 is provided at the bottom of the first settling area 2 , and a sewage valve is provided on the first sewage pipe 22 .

[0032] A second sewage pipe 31 is provided at the bottom of the second sedimentation zone 3 , and a sewage valve is provided on the second sewage pipe 31 .

[0033] A second inspection cover 51 is provided at the upper end of the filtration area 5. The inspection cover can facilitate inspection and maintenance of the sedimentation tank.

[0034] A third drain pipe 73 is provided at the bottom left of the aeration purification tank 7, and a drain valve is provided on the third drain pipe 73. During cleaning, the drain pipe can discharge filtered impurities and other objects without affecting subsequent use.

[0035] Among them, the interception net and the filter net are both made of 304 stainless steel mesh.

[0036] The working principle of the present invention is as follows: when in use, the sewage in the sewage pool enters the sedimentation and filtration tank through a water pump, and now settles in the first sedimentation area, and undergoes the first interception and filtration through the interception net. After that, the water will pass through the water trough into the second sedimentation area, and then the water level rises, and is filtered in sequence between the first filter screen 41, the filter medium 43, and the second filter screen 42 of the filter assembly 4, and rises to the filtration area. The filtered water is discharged into the aeration purification tank through the filtered water outlet pipe. A water pump can be added to extract it to speed up the entry of the filtered water into the aeration purification tank. By starting the aerator and the servo motor for stirring, the air flow is fully mixed with the water supplied, so that impurities are suspended in the upper layer of the water, thereby accelerating the aeration efficiency. The clear water below is extracted by the second water pump and sent to the subsequent clean water tank. When cleaning is needed later, the dirt intercepted by the interception net and the filter assembly can be discharged by opening the drain valve on the first drain pipe and the drain valve on the second drain pipe.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements shall fall within the scope of the present invention as claimed.

Any details not described in the present invention are well known to those skilled in the art.
