Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Example 1

The aerobic tank wastewater treatment device comprises an aerobic tank 4, wherein a first baffle 7 and a second baffle 12 are arranged in the aerobic tank 4, and the first baffle 7 and the second baffle 12 divide the aerobic tank 4 into a first water storage chamber 41, a filter chamber 42 and a second water storage chamber 43 which are independent from left to right in sequence;

a filter plate 10 is arranged in the filter chamber 42 to divide the filter chamber 42 into an upper part and a lower part, two ends of the filter plate 10 are respectively connected with the first baffle plate 7 and the second baffle plate 12, the first baffle plate 7 above the filter plate 10 and the second baffle plate 12 below the filter plate 10 are both of filter screen structures,

a packing layer 9 (e.g. polyurethane bio-packing) is also provided in the filter chamber 42, the packing layer 9 being located below the filter plate 10.

In this embodiment, an aeration device 8 is further disposed in the filtering chamber 42, and the aeration device 8 is located at the bottom of the filtering chamber 42; thereby better carrying out aerobic respiration, further decomposing organic matters into inorganic matters and removing pollutants.
