[0023] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0024] Please refer to Figures 1-4 The present application provides a technical solution:

[0025] The solar micro-power sewage treatment system comprises an aeration tank 1, an anaerobic tank 2, an aerobic tank 3, a sedimentation tank 4 and a solar power generation device 5 for supplying power to the solar micro-power sewage treatment system, and an air blower 6 for providing air for the aeration tank 1 and the aerobic tank 3. The above-mentioned various structures are prior art, and the specific treatment principle of the sewage is not further described here.

[0026] The improvement of the present application over the prior art will be introduced below.

[0027] Specifically, a transition tank 9 is fixedly connected to one side of the top of the aeration tank 1, the transition tank 9 is directly communicated with the aeration tank 1, the sewage transported by the water inlet pipe 7 flows into the inside of the transition tank 9 after being collected by the collecting assembly 8, and the sewage in the transition tank 9 can directly flow into the inside of the aeration tank 1 for aeration treatment. The collecting assembly 8 is used for collecting long hair and filamentous substances similar to long hair in the sewage, so as to prevent damage to the related treatment equipment in the subsequent treatment process.

[0028] The collecting assembly 8 comprises a U-shaped groove 81 and a plurality of filter combs fixed in the U-shaped groove 81. The U-shaped groove 81 can be made of stainless steel or plastic, and is used to guide the sewage delivered by the water inlet pipe 7 into the transition tank 9. The filter combs inside the U-shaped groove 81 can intercept the long hair and the hair-like filaments in the sewage, so as to prevent them from entering the aeration tank 1. The filter combs are arranged along the length direction of the U-shaped groove 81. In this embodiment, the spacing between the filter combs is equal. Each filter comb comprises a plurality of comb needles 84 arranged along the width direction of the U-shaped groove 81, and a horizontal plate 83. The top ends of the comb needles 84 are fixedly connected to the horizontal plate 83. In this embodiment, the spacing between the comb needles 84 is equal. The bottom ends of the comb needles 84 are in contact with the bottom of the U-shaped groove 81, and the comb needles 84 are perpendicular to the bottom surface of the U-shaped groove 81. The diameter of the comb needles 84 is between 1-2 mm, which can effectively intercept the long hair and the hair-like filaments in the sewage. Subsequently, the long hair and the hair-like filaments wound on the comb needles 84 can be cleaned regularly.

[0029] In this embodiment, the positions of the comb needles 84 of the adjacent two filter combs are staggered, as shown in the figure. In this way, the long hair and the hair-like filaments in the sewage can be intercepted as much as possible by the staggered comb needles 84. Figure 3

[0030] In the above scheme, the U-shaped groove 81 is arranged below the water outlet of the water inlet pipe 7, so that the sewage needs to flow through the U-shaped groove 81 before flowing into the aeration tank 1. Then, the long hair and the hair-like filaments in the sewage can be intercepted by the comb needles 84 of the filter combs arranged in the U-shaped groove 81, so as to prevent them from entering the aeration tank 1. In this way, the damage of the pump body and other devices in the sewage treatment equipment caused by the long hair and the hair-like filaments can be avoided, and the processing safety of the entire sewage treatment equipment is improved.

[0031] In this embodiment, the U-shaped groove 81 is arranged obliquely, and has a low end and a high end. The sewage delivered by the water inlet pipe 7 flows into the U-shaped groove 81 from the high end, and then flows out from the low end and enters the transition tank 9. In this way, the sewage in the U-shaped groove 81 can quickly flow into the aeration tank 1. Furthermore, in order to prevent the sewage from overflowing from the high end of the U-shaped groove 81 due to impact and spatter, an end plate 82 is fixed at the high end of the U-shaped groove 81. The end plate 82 is used to block the high end of the U-shaped groove 81, so as to ensure that the sewage can flow from the high end to the low end of the U-shaped groove 81, and the interception effect of the long hair and the hair-like filaments is guaranteed.

[0032] ​The hook needle 85 is fixed on the water surface of the bottom end of the comb needle 84, the length of the hook needle 85 is parallel to the slot length direction of the U-shaped slot 81, further, the cross section shape of the hook needle 85 is a right triangle, two right angle sides of the hook needle 85 are respectively contacted with the comb needle 84 and the slot bottom of the U-shaped slot 81, the oblique side of the hook needle 85 is gradually raised along the sewage flowing direction, the function of the hook needle 85 is that the long hair and the similar long hair silk wrapped on the comb needle 84 can be lifted together when the filter comb is lifted, and the long hair and the similar long hair silk are convenient to clean.

[0033] The filter comb further comprises a pair of symmetrically fixed plug plates 86 on the two side walls of the U-shaped slot 81, the plug plates 86 are provided with plug slots 87, and the two ends of the horizontal plate 83 are inserted into the plug slots 87, so that the plug connection between the filter comb and the U-shaped slot 81 is realized, and the installation and dismounting of the filter comb are facilitated.
