DETAILED DESCRIPTION

[0016] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.

[0017] Embodiment 1

[0018] As Figs. 1-3As shown, the utility model provides a technical scheme: a sewage treatment tank, including sewage treatment tank shell 1, the top and the side lower end of sewage treatment tank shell 1 are respectively fixed with water inlet pipe 2 and water outlet pipe 3, sewage enters sewage treatment tank shell 1 from water inlet pipe 2, and the sewage after purification flows out from water outlet pipe 3, and the inside of sewage treatment tank shell 1 is placed with activated carbon layer 4, and activated carbon layer 4 plays the filtering purification effect to sewage, the inner surface of sewage treatment tank shell 1 is fixedly connected with filter screen plate 5 at the upper end of activated carbon layer 4, and the large sundries in sewage are filtered out under the action of filter screen plate 5, and electric telescopic rod 6 is fixedly penetrated on the outside of sewage treatment tank shell 1, and one end of electric telescopic rod 6 is fixed with push plate 7, one side of push plate 7 is fixed with connecting rod 8, and one end of connecting rod 8 is fixed with closed arc plate 9, and the outer surface of sewage treatment tank shell 1 is provided with passageway, and closed arc plate 9 is engaged in passageway, the large sundries in sewage are filtered out under the action of filter screen plate 5, by making electric telescopic rod 6 extend, push plate 7, connecting rod 8 and closed arc plate 9 are driven to move outward, so that push plate 7 can push out the large sundries accumulated on filter screen plate 5 from passageway outward, plays the removal effect to sundries on filter screen plate 5, avoids the influence of normal filtration of activated carbon layer 4 to sewage due to too much sundries accumulation, and the outside surface of sewage treatment tank shell 1 is fixed with controller 13, and electric telescopic rod 6 is set to carry out telescopic operation every interval time through controller 13, so as to make push plate 7 periodically remove the sundries accumulated on filter screen plate 5 outward.
