Detailed Embodiment

[0017] Such as Figures 1-6Shown: A sewage treatment device for water environment treatment, including a sedimentation tank 1, a purification tank 2, and a filtration tank 3 arranged in sequence from left to right. There is a water overflow tank 4 fixedly connected between the right top of the sedimentation tank 1 and the left top of the purification tank 2. The water overflow tank 4 penetrates from left to right and slopes downward to the right. The left side of the sedimentation tank 1 has a waste water inlet pipe 5, and the right end of the waste water inlet pipe 5 extends to the top of the sedimentation tank 1. The bottom of the left side wall of the sedimentation tank 1 is fixedly communicated with a sludge discharge pipe 6. The front side of the purification tank 2 is fixedly connected with a chemical dosing mechanism. The top of the left side wall of the filtration tank 3 is fixedly installed with a water pump 13. The input end of the water pump 13 is fixedly communicated with a water suction pipe 14, and the water suction pipe 14 extends to the inner bottom of the purification tank 2. The output end of the water pump 13 is fixedly communicated with a water outlet pipe 15, and the water outlet pipe 15 extends to the top of the filtration tank 3. The inner side wall of the filtration tank 3 is slidably fitted with a movable frame 16. The inner side wall of the movable frame 16 is fixedly connected with three layers of filter plates 17 arranged vertically. The bottom of the rear side wall of the purification tank 2 is fixedly communicated with a sludge discharge pipe 18. The bottom of the right side wall of the filtration tank 3 is fixedly communicated with a drain pipe 19. Valves are installed on the waste water inlet pipe 5, the sludge discharge pipe 6, the sludge discharge pipe 18, and the drain pipe 19.

[0018] The chemical dosing mechanism includes a lifting pipe 7. The lifting pipe 7 is arranged vertically and fixedly connected to the front side wall of the purification tank 2. The bottom of the front side wall of the lifting pipe 7 is fixedly communicated with a chemical dosing hopper 8. A rotating shaft 9 is rotatably connected between the inner top wall and the inner bottom wall of the lifting pipe 7. A reamer 10 is fixedly connected to the outer wall of the rotating shaft 9. The reamer 10 is spiral-shaped, and the outer wall of the reamer 10 is in clearance fit with the inner wall of the lifting pipe 7. The top of the lifting pipe 7 is fixedly installed with a motor 11, and the output shaft of the motor 11 is fixedly connected to the top of the rotating shaft 9. The top of the rear side wall of the lifting pipe 7 is fixedly communicated with a medicine delivery pipe 12, and the medicine delivery pipe 12 extends above the purification tank 2.

[0019] The sewage first enters the sedimentation tank 1 through the waste water inlet pipe 5. In the sedimentation tank 1, the large-particle suspended substances in the sewage gradually settle to the bottom of the tank under the action of gravity.

[0020] When the sludge accumulated at the bottom of the sedimentation tank 1 reaches a certain amount, the valve of the sludge discharge pipe 6 is opened to discharge the sludge at the bottom to maintain the normal operation of the sedimentation tank 1.

[0021] The sedimented sewage flows into the purification tank 2 through the water overflow tank 4 that slopes downward to the right. Pour the chemical agent into the chemical dosing hopper 8. The motor 11 drives the rotating shaft 9 to rotate, driving the spiral reamer 10 to rotate in the lifting pipe 7. The rotation of the reamer 10 lifts and mixes the agent upward, and finally sprays it into the sewage in the purification tank 2 through the medicine delivery pipe 12. The chemical agent reacts with the harmful substances in the sewage to achieve the purpose of purifying the water quality. The sludge discharge operation can be carried out by opening the valve of the sludge discharge pipe 18.

[0022] The purified sewage is pumped out from the inner bottom of the purification tank 2 through the water suction pipe 14 under the action of the water pump 13, and then pumped into the filtration tank 3 through the water outlet pipe 15.

[0023] There are three layers of filter plates 17 arranged vertically in the filtration tank 3. The sewage passes through these three layers of filter plates 17 in sequence for filtration. Each layer of filter plate 17 can intercept impurities with different particle sizes, and finally further purify the water quality.

[0024] The filtered clean water is discharged through the drain pipe 19 and can be reused or discharged into the natural water body after meeting the treatment standards. The present utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the present utility model.
