Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a microbial mixing treatment device for activated sludge treatment. Background Art

[0002] Activated sludge is a general term for microbial communities and the organic and inorganic substances they are attached to. Activated sludge can be divided into aerobic activated sludge and anaerobic granular activated sludge. Activated sludge is mainly used to treat sewage and wastewater. The activated sludge method is an aerobic treatment method that uses suspended microbial flocs to treat organic sewage. When observing these brown flocculent sludges under a microscope, you can see a large number of bacteria, as well as fungi, protozoa and metazoa, which form a unique ecosystem. It is these microorganisms (mainly bacteria) that use organic matter in sewage as food, metabolize and reproduce, which reduces the content of organic matter in sewage.

[0003] According to the Chinese patent publication number CN 218012207 U, an activated sludge mixing device for sewage treatment is disclosed, which belongs to the technical field of sewage treatment. The key points of its technical solution include a mixing tank, the inner bottom end of the mixing tank is rotatably connected to a rotating shaft, the outer wall of the rotating shaft is fixedly connected to a plurality of evenly distributed stirring rods, the left side of the mixing tank is connected to a sewage inlet pipe, the left side of the upper end face of the mixing tank is connected to an activated sludge conveying pipe, the material equalizing device is arranged inside the mixing tank, and is used to evenly mix the activated sludge and sewage. Specifically, the activated sludge enters the mixing tank, the first motor drives the driving wheel and the driven wheel to rotate, the driven wheel drives the rotating rod and the material equalizing plate to rotate, when the activated sludge flows down, the material equalizing plate rotates inside the annular groove, and the activated sludge falls through the plurality of discharge holes on the material equalizing plate, so that the activated sludge is scattered more evenly and effectively, and the local accumulation and agglomeration of the activated sludge is prevented, which affects the uniformity of the mixing of the activated sludge and sewage, and the mixing effect is good.

[0004] However, the number of stirring rods in the activated sludge mixing device is small, resulting in low efficiency in mixing activated sludge and sewage, and poor mixing effect, which affects the efficiency of sewage treatment. At the same time, although the material balancing plate in the device can scatter the activated sludge, it is easy to accumulate on the edge of the material balancing plate when the material balancing plate rotates, affecting the discharge of the material. For this reason, we propose a microbial mixing treatment device for activated sludge treatment. Utility Model Content
