Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. 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.
[0021] see Figure 1~3 , in an embodiment of the present invention, an aeration tank for domestic sewage treatment with a time delay plate includes a tank body 1, a bracket 2, a frame 7, an aeration plate 8 and a blower 9; the top right of the tank body 1 The water inlet pipe 11 is arranged on the side, and the mouth of the water inlet pipe 11 is facing the opening of the pool body 1. The bottom right side of the pool body 1 is connected with a drain pipe 12. ...

The invention discloses a domestic sewage treatment aeration tank with delay plates. The domestic sewage treatment aeration tank comprises a tank body, a support frame, frames, an aeration plate and ablast blower; the support frame is fixedly arranged at the top of the tank body; the aeration plate is arranged at the bottom of the tank body; the frames are fixedly arranged on the inner cavity wall of the tank body; and the delay plates are arranged in the frames. When the domestic sewage treatment aeration tank works, the stirring ranges of stirring blades are widened due to the up-and-down movement of a slip sleeve, so that sewage is in sufficient contact with air bubbles, and the aeration efficiency is increased; the aeration plate can rotate with a rotating shaft, so that the air bubbles are more uniformly distributed in the sewage, and aeration dead angles are avoided; and meanwhile, the air bubbles can move along inclined surfaces of the delay plates in an ascending process, so that the staying time of the air bubbles in a region acted by the stirring blades is prolonged, the sufficient contact between the sewage and the air bubbles is further strengthened, and the aeration efficiency is increased.
Description
technical field [0001] The invention relates to the field of domestic sewage, in particular to an aeration tank for domestic sewage treatment with a delay plate. Background technique [0002] Domestic sewage is mainly the discharge water produced by various kitchen water, washing water and toilet water used in human life, and most of them are non-toxic inorganic salts. Sewage produced in the process of human life is one of the main sources of water pollution. [0003] The aeration tank is a common device for domestic sewage treatment. The aeration tank uses the activated sludge method for sewage treatment. The tank provides a certain sewage residence time to meet the oxygen required by aerobic microorganisms and the sewage and activated sludge. Mixed conditions of full contact. [0004] Most of the aeration components in the existing aeration tank allow the bubbles to float freely after forming oxygen-containing bubbles, and the contact between the bubbles and the sewage i...
