An insert block 11 is arranged at the bottom of the grading treatment barrel, and the insert block 11 is inserted and installed in the slot 3-1, so that the grading treatment barrel is arranged on the installation frame 3. The barrel cover 1 is buckled and installed on the upper part of the whole composed of the central screening barrel 2 and the plurality of grading treatment barrels to form an integral structure. The overall structure of the treatment barrel body is cylindrical, and the barrel cover 1 is airtight with the plurality of grading treatment barrels to prevent the sewage between the grading treatment barrels from overflowing from the upper part of the barrel mouth when the sewage is full;

[0032] In the present invention, specifically, the graded treatment barrels include a primary sedimentation barrel 4, a chemical sedimentation barrel 5, a physical filtration barrel 6, a disinfection barrel 7 and a clean water collection barrel 8, and the primary sedimentation barrel 4, the chemical sedimentation barrel 5, the physical filtration barrel 6, the disinfection barrel 7 and the clean water collection barrel 8 are sequentially arranged on the mounting frame 3 in a surrounding manner, and the primary sedimentation barrel 4 is connected to the central screening barrel 2 by the diversion component 10, and the primary sedimentation barrel 4, the chemical sedimentation barrel 5, the physical filtration barrel 6, the disinfection barrel 7 and the clean water collection barrel 8 are connected in pairs through connecting pipes 9, wherein the clean water collection barrel 8 is not back-connected to the primary sedimentation barrel 4 (the clean water collection barrel 8 is not connected to the primary sedimentation barrel 4), and the connecting pipe 9 is set at different positions, as described in detail below.

[0033] In the present invention, the central screening barrel 2 includes a driving assembly, a chute 2-1 and a filter screen barrel 2-2, and the chute 2-1 is arranged on the inner wall of the central screening barrel 2;

[0034] The driving assembly includes a rack 2-3, a driven gear 2-4, a driven gear mounting frame 2-5, a driving motor 2-6 and a driving gear 2-7. The rack 2-3 is arranged on the outer wall of the filter screen barrel 2-2. The rack 2-3 is arranged higher than the upper end surface of the filter screen barrel 2-2. The rack 2-3 is slidably arranged in the slide groove 2-1. The driven gear mounting frame 2-5 is installed on the barrel mouth end surface of the central screening barrel 2. The driven gear 2-4 is rotatably installed on the driven gear mounting frame 2-5. The driving motor 2-6 is detachably installed on the On the barrel cover 1, the output end of the driving motor 2-6 is provided with the driving gear 2-7, and the driving gear 2-7 and the driven gear 2-4 are respectively meshed and connected with the rack 2-3, and the filter screen barrel 2-2 is lifted out of the central screening barrel 2 by the driving of the driving motor 2-6, and the upper port of the filter screen barrel 2-2 can also be provided with a lifting ring, so that after the driving component lifts out the filter screen barrel 2-2, the barrel is manually lifted out and then the larger garbage and dirt filtered out of the barrel is dumped out and then the filter screen barrel 2-2 is reinstalled;

[0035] Furthermore, a removable pressure cover net 2-8 is provided in the filter screen barrel 2-2. The pressure cover net 2-8 is funnel-shaped and inverted into the filter screen barrel 2-2. The center position of the pressure cover net 2-8 is connected to an inlet pipe 2-9, and the inlet pipe 2-9 is connected to an external sewage supply unit. The inlet pipe 2-9 leads to the bottom of the pressure cover net 2-8, so as to guide the sewage to the bottom of the pressure cover net 2-8. If there is larger garbage or dirt, it can be blocked by the pressure cover net 2-8 under the net to achieve pre-filtration. The sewage after the first layer of filtration is located above the pressure cover net 2-8 to facilitate the extraction of the guide component 10, and the garbage that is easy to float can also be blocked by the pressure cover net 2-8 to the bottom of the net body to wait for the operator to collect the full dirt for unified treatment.

[0036] In the present invention, the diversion component 10 includes a water pump 10-1, a water suction pipe 10-2 and a water outlet pipe 10-3. The water pump 10-1 can be detachably installed on the barrel cover 1. The water pump 10-1 is connected to the water suction pipe 10-2 and the water outlet pipe 10-3. The water suction pipe 10-2 is connected to the filter screen barrel 2-2 and is located above the pressure cover net 2-8. The water outlet pipe 10-3 is connected to the primary sedimentation barrel 4. The diversion component 10 extracts the water after the first filtration through the pressure cover net 2-8, and diverts the sewage after the first filtration to the primary sedimentation barrel 4 for primary sedimentation operation. The purpose of primary sedimentation is to allow the silt and mud in the sewage to be densely packed. The sewage with a density greater than that of water automatically sinks under its own weight and forms a stratification phenomenon in the primary sedimentation barrel 4. The connecting pipe 9 between the primary sedimentation barrel 4 and the chemical sedimentation barrel 5 is arranged near the port of the barrel. The connecting pipe 9 is in an inverted L shape. The water inlet of the connecting pipe 9 is arranged near the barrel mouth of the primary sedimentation barrel 4, and the water outlet of the other end is toward the bottom of the chemical sedimentation barrel 5. Since the barrel cover 1 and the primary sedimentation barrel 4 and the chemical sedimentation barrel 5 are airtight, when the sewage in the primary sedimentation barrel 4 is full, the cleaner water above the stratified sewage after preliminary sedimentation in the primary sedimentation barrel 4 will flow into the chemical sedimentation barrel 5 along the connecting pipe 9, forming a step-by-step treatment step.

[0037] In the present invention, a plurality of reinforcing ribs 1-1 are provided on the upper surface of the barrel cover 1, and observation windows 1-2 are provided between the reinforcing ribs 1-1 and the reinforcing ribs 1-1. Each of the observation windows 1-2 corresponds to an upper port of the grading treatment barrel. Specifically, a chemical agent introduction port is provided on the observation window 1-2 corresponding to the top of the chemical sedimentation barrel 5. Suitable chemical agents are selected according to the specific sewage conditions, such as coagulants, defoaming agents, pH adjusters, redox agents, disinfectants, conditioners, demulsifiers, flocculants, etc.

[0038] In the present invention, the upper middle position inside the physical filter barrel 6 is filled with clean water filter material, and the clean water filter material is lower than the barrel mouth of the physical filter barrel 6. The principle is the same as that of the central screening barrel 2, so that the filtered clean water is located above the clean water filter material, so that a height difference is formed between the treated clean water in the physical filter barrel 6 and the disinfection barrel 7, and the clean water can more conveniently flow into the disinfection barrel 7 for the final step of disinfection treatment. One end of the connecting pipe 9 between the chemical sedimentation barrel 5 and the physical filter barrel 6 is arranged at a position close to the barrel mouth of the chemical sedimentation barrel 5, and the other end is inserted into the position below the clean water filter material. The sewage treated by the chemical sedimentation barrel 5 flows into the physical filter barrel 6 and is located below the clean water filter material. After filtering and adsorption by the clean water filter material, it overflows from the top of the filter material. Common clean water filter materials can be purchased on the market, and conventional ingredients include: filter cotton, activated carbon, quartz sand, etc.

[0039] The clean water obtained through the layer-by-layer purification treatment is connected to the clean water discharge pipe through the observation window 1-2 above the clean water collection barrel 8 for use as clean water.

[0040] To sum up, the utility model provides a small and efficient sewage treatment barrel, which is assembled from a central screening barrel, a mounting frame and several graded treatment barrels, and the graded treatment barrels include a primary sedimentation barrel, a chemical sedimentation barrel, a physical filtration barrel, a disinfection barrel and a clean water collection barrel.
