Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in the attached figure, the gravity-type equipment intelligently controls the backwash sewage treatment system, including the aeration dissolved oxygen water separator 3, the drainage system and four sets of filter units, each set of filter units is equipped with a set of siphon systems, the aeration The dissolved oxygen water separator 3 is located at the upper center of the four groups of filter units.

When filtering, the sewage first enters the aeration dissolved oxygen water separator 3 to aerate the harmful gas in the sewage, and at the same time increases oxygen, and then enters the four sets of filter units for purification and filtration before being discharged.

Further, each group of filter units includes a water inlet pipe 1, an outlet pipe 2 and a clean water tank 4, the water inlet pipe 1 is connected with the aeration dissolved oxygen water separator 3 and the siphon system, and the aeration dissolved oxygen water separator 3 is connected with the The clean water tank 4 is connected, and the outlet pipe 2 is connected with the clean water tank 4. Inside the clean water tank 4, a clean water area 6, a water inlet area 7, a filter area 8 and a water collection area 9 are arranged from top to bottom, the siphon system and the drainage pool 5 are connected, and the drainage pool 5 is connected with a backwash sewage pipe 10; an electric valve is set on the water inlet pipe 1, and an auxiliary electric valve is set on the siphon system.

By setting the aeration dissolved oxygen water separator, the sewage enters the aeration dissolved oxygen water separator from the water inlet pipe for aeration and dissolved oxygen, blasts the harmful gas in the sewage, and then enters the water inlet area of the clean water tank, The filtering operation is carried out through the filter area located at the lower part of the water inlet area. The filtered water enters the water collection area, and then the water in the water collection area is pumped upwards into the clean water tank through the connecting pipe, and finally flows out from the outlet pipe. to complete filtering.

Specifically, the filter area is formed by intervals of filter tanks. The filter tank includes a tank body 23 , a filter layer 24 is arranged in the middle of the tank body 23 , and a supporting layer 25 is arranged at the bottom of the filter layer 24 .

The supporting layer 25 is used to support the filter layer, and the sewage is filtered in the tank.

In order to introduce the filtered clean water into the clean water area, four connecting pipes 26 are arranged on the outside of each clean water tank 4. The mouth is connected with the clear water area 6.

Clean water tank 4 is provided with an inspection port for convenience to the internal maintenance of clean water tank.

Preferably, the clean water tank 4, the siphon breaking pipe 12, the siphon ascending pipe 11, the siphon descending pipe 13 and the siphon auxiliary pipe 14 are made of UPVC.

Since the sewage contains a large amount of impurities, when filtering through the filter layer, the impurities will remain on the surface of the filter layer, causing the filter layer to block, thereby affecting the filtration. Therefore, a siphon system is set up to remove the impurity water on the filter layer through the principle of siphon. Take away.

Specifically, the siphon system includes a siphon rising pipe 11 connected to the water inlet area, a siphon descending pipe 13 connected with the siphon rising pipe, the water outlet of the siphon descending pipe 13 communicates with the drain pool 5, and the siphon rising pipe 11 A siphon auxiliary pipe 14 and a siphon breaking pipe 12 are arranged between the siphon descending pipe.

In order to realize the automatic control of backwashing, an electric valve is set on the water inlet pipe 1, and an auxiliary electric valve is set on the siphon system.

A2 auxiliary electric valve 20, A3 auxiliary electric valve 21 and A4 auxiliary electric valve 22, A1 auxiliary electric valve 19 cooperates with B1 electric valve 15, A2 auxiliary electric valve 20 cooperates with B2 electric valve 16, A3 auxiliary electric valve 21 cooperates with B3 electric valve 17, and A4 auxiliary electric valve 22 cooperates with B4 electric valve 18.

The working principle of the present invention is: when it is filtered normally, the sewage enters the aeration and dissolved oxygen water separator 3 from the water inlet pipe, aerates and dissolves oxygen, blasts the harmful gas in the sewage, and then enters the clean water tank. In the water area, the filtering operation is carried out through the filter area located at the lower part of the water inlet area. The filtered water enters the water collection area, and then the water in the water collection area is pumped upwards into the clean water tank through the connecting pipe, and finally from the The outlet pipe flows out to complete the filtration; when backwashing, open the B1 electric valve 15, and the water enters the siphon descending pipe 13 from the water inlet pipe, and because the water flows downward through gravity, the air in the pipe is taken away during the flow, and Through the siphon ascending pipe, the impurities in the filter tank are pumped up to form a siphon, and then enter the siphon descending pipe, flow down into the drainage pool, and be drained through the backwash sewage pipe 10, when the siphon is formed for about three minutes Close the B1 electric valve 15 to reserve enough time for sludge pumping. After closing the B1 electric valve 15 for about three minutes, open the A1 auxiliary electric valve 19, and the air enters from the siphon breaking pipe to destroy the formed siphon to complete the first one. The backwash operation of the filter unit, and so on, carry out the backwash operation of the subsequent three filter units.

The present invention uses an electric valve to replace the cumbersome manual operation in the past, makes the filtration more intelligent and automatic, has good filtering effect and backwashing effect, and improves the service life of the treatment system.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
