Treatment area and sewage treatment area; the sewage treatment area is provided with a pressing device, a water inlet pipe and a filter screen in sequence from top to bottom. In the initial state of the pressing device, the water inlet pipe is located below the pressing device, and the pressing When the device is in working state, the water inlet pipe is located above the pressing device; the odor treatment area is provided with an exhaust pipe and a filter element in sequence from top to bottom, and a ventilation hole with an air valve is provided at the lower part of the baffle; The physical treatment pool and the purification pool are connected by a first water pump, and the purification pool and the chemical treatment pool are connected by a second water pump.

Further, the pressing device includes a hydraulic cylinder, a hydraulic rod and a piston, the initial state of the piston is located above the water inlet pipe, and when the piston is pressed down to the lowest position, the water inlet pipe is located above the piston.

Further, the filter element includes a microorganism adsorption plate and an activated carbon plate in sequence from top to bottom.

Further, the purification tank is provided with a purification device.

Further, the purification device includes a blower and a purifier, the purifier is fixedly connected in the purification pool, and the air outlet of the blower extends into the interior of the purifier.

The beneficial effects are: the sewage is discharged from the water inlet pipe to the sewage treatment area in the physical treatment tank, and the large debris is filtered by the filter screen. After the device passes through the water inlet pipe, the air below the lower pressure device is no longer circulated, and the pressure increases, which forces the sewage to be filtered from the filter screen to speed up the filtration rate of sewage; The pressure of the lower part of the device still increases, open the air valve, so that the odor is quickly squeezed into the odor treatment area, and flows upward through the filter element, and finally is discharged through the exhaust pipe; The filtration rate of the net also promotes the rate of odor treatment in the sewage.

Detailed ways

The technical scheme of a sewage treatment and purification device involved in the present invention will be further described in detail below with reference to the embodiments.

As shown in FIG. 1-FIG. 2, a sewage treatment and purification device 14 of the present embodiment is provided with a physical treatment tank 1, a purification tank 2 and a chemical treatment tank 3 in sequence according to the flow direction of the sewage. The physical treatment tank 1 is composed of a partition plate 4 is divided into an odor treatment area 102 and a sewage treatment area 103; the sewage treatment area 103 is sequentially provided with a lower pressure device 5, a water inlet pipe 6 and a filter screen 7 from top to bottom. In the initial state of the lower pressure device 5, The water inlet pipe 6 is located below the lower pressure device 5. When the lower pressure device 5 is in operation, the water inlet pipe 6 is located above the lower pressure device 5; the odor treatment area 102 is sequentially provided with an exhaust pipe 11 and a filter from top to bottom The lower part of the partition plate 4 is provided with a ventilation hole with an air valve 8; The connection is via the second water pump 13 .

Working principle: The sewage is discharged from the water inlet pipe 6 to the sewage treatment area 103 in the physical treatment tank 1, and the extremely large debris is filtered by the filter screen 7. At this time, the larger debris will block some of the filter holes, and the lower pressure device will be activated. 5. After the pressing device 5 passes through the water inlet pipe 6, the air below the pressing device 5 is no longer circulated, and the pressure increases, and the sewage is forced to speed up the filtration from the filter screen 7, and the filtration rate of the sewage is accelerated; After the sewage flows through the filter screen 7, the pressure of the lower part of the pressing device 5 still increases, and the air valve 8 is opened, so that the odor is quickly squeezed into the odor treatment area 102, and flows upward through the filter element, and finally passes through the exhaust. The air pipe 11 is removed; the pressing device 5 not only accelerates the filtration rate of the filter screen 7, but also promotes the rate of odor treatment in the sewage.

In this embodiment, the pressing device 5 includes a hydraulic cylinder 502, a hydraulic rod 503 and a piston 504. The initial state of the piston 504 is located above the water inlet pipe 6. When the piston 504 is pressed down to the lowest position, the water inlet pipe 6 is above piston 504.

In this embodiment, the filter element includes a microorganism adsorption plate 10 and an activated carbon plate 9 in order from top to bottom.

After the odor passes through the activated carbon plate 9 and the microorganism adsorption plate 10 successively, the exhaust pipe 11 is discharged, which effectively removes the damage of the odor to the environment and the impact on people; an exhaust fan can also be installed in the exhaust pipe 11. , to speed up the discharge of odor.

As shown in FIG. 3, the purification tank 2 of this embodiment is provided with a purification device 14; the purification device 14 includes a blower 1402 and a purifier 1403, the purifier 1403 is fixedly connected in the purification tank 2, and the blower The air outlet of 1402 extends into the interior of the purifier 1403.
