DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to better understand the above technical solutions, the following will specifically describe the above technical solutions in detail in combination with the accompanying drawings of the specification and specific embodiments.

[0021] The embodiment of the present invention discloses a small integrated sewage treatment equipment.

[0022] According to the appendix Figure 1-2As shown in the figure, it includes a device housing 1. A water inlet pipe 2 and a water outlet pipe 3 are fixedly installed on both sides of the device housing 1 respectively. A partition plate 11 is fixedly installed inside the device housing 1, and the internal space of the device housing 1 is divided into upper and lower cavities by the partition plate 11;

[0023] The lower cavity includes a water inlet area 12 and an air-lift area 13, and the upper cavity includes a packing area 14 and a water outlet area 15;

[0024] An air diffuser pipe 16 is arranged inside the air-lift area 13, and an air-lift return pipe 17 is arranged between the air-lift area 13 and the packing area 14.

[0025] During the use process, sewage enters from the water inlet pipe 2. At this time, the lower part of the air-lift area 13 is aerated by a blower in cooperation with the air diffuser pipe 16. When the sewage reaches the air-lift area 13 from the water inlet area 12, the steam-water mixture uses the air-lift principle to realize reflux and lift into the packing area 14, then the water flow passes through the packing area 14 and enters the water outlet area 15, and finally is discharged through the water outlet pipe 3. At the same time, when the sewage passes through the packing area 14, the pollutants in the sewage are treated by the biofilm formed in the packing area 14 to achieve the purpose of water quality treatment. Furthermore, the air-lift principle can be used to lift the sewage to the packing area 14 to achieve the effect of water quality treatment, without auxiliary water pumps or lift pumps, saving energy consumption.

[0026] Furthermore, the water inlet area 12 is communicated with the end of the water inlet pipe 2.

[0027] Furthermore, the water outlet area 15 is communicated with the end of the water outlet pipe 3.

[0028] Specifically disclosed, the air diffuser pipe 16 includes an air inlet pipe 161 and a horizontal pipe 162. One end of the air inlet pipe 161 extends through the device housing 1 to the outside and is connected to a blower, the other end of the air inlet pipe 161 is connected to the horizontal pipe 162, and a plurality of air diffusers are arranged on the outer side of the horizontal pipe 162 and are horizontally arranged inside the air-lift area 13.

[0029] During the use process, one end of the air inlet pipe 161 extends through the device housing 1 to the outside and is connected to a blower, and then the outside air is input into the horizontal pipe 162, and is aerated outward by a plurality of air diffusers arranged on the outer side of the horizontal pipe 162.

[0030] Specifically disclosed, the air-lift return pipe 17 includes a connecting pipe 171 and a return pipe 172. The bottom end of the connecting pipe 171 is inserted into the air-lift area 13, and the top end of the connecting pipe 171 passes through the top of the device housing 1 and is connected to the return pipe 172, and the other end of the return pipe 172 passes through the top of the device housing 1 and extends into the inside of the packing area 14.

[0031] After the gas-liquid mixture enters the connecting pipe 171, it then enters the return pipe 172 and enters the inside of the packing area 14 through the return pipe 172.

[0032] Further, a first baffle plate 18 is fixedly installed at the bottom of the partition plate 11. The lower cavity is divided into a water inlet area 12 and an air-lift area 13 by the provided first baffle plate 18.

[0033] Further, a second baffle plate 19 is installed on the inner top wall of the equipment housing 1. The upper cavity is divided into a packing area 14 and a water outlet area 15 by the provided second baffle plate 19.

[0034] During the use process, sewage enters from the water inlet pipe 2. At this time, the lower part of the air-lift area 13 uses a blower to cooperate with the aeration pipe 16 for aeration. When the sewage reaches the air-lift area 13 from the water inlet area 12, the steam-water mixture uses the air-lift principle to input pressurized air through the bottom of the air input air-lift return pipe 17. A gas-liquid mixture with a density less than that of the mixed liquid outside the pipe is formed in the air-lift return pipe 17. According to the liquid balance principle, the liquid level of the gas-liquid mixture with a relatively small specific gravity is higher than that of the mixed liquid outside the pipe. Under the combined action of the suction force formed by the upward rise of the gas-liquid mixture in the pipe and the pressure of the mixed liquid outside the pipe, the mixed liquid outside the pipe continuously surges in from the bottom of the lift pipe, thereby realizing the reflux and lifting into the packing area 14. Then the water flow passes through the packing area 14 and enters the water outlet area 15, and finally is discharged through the water outlet pipe 3. At the same time, when the sewage passes through the packing area 14, the pollutants in the sewage are treated by using the biofilm formed in the packing area 14 to achieve the purpose of water quality treatment. Furthermore, the air-lift principle can be used to lift the sewage to the packing area 14 to achieve the effect of water quality treatment, without an auxiliary water pump or a lifting water pump, saving energy consumption.
