Biological floating body for purifying sewage based on biological method and sewage purification method thereof

Abstract

The invention discloses a biological floating body for purifying sewage based on a biological method and a sewage purification method thereof. The biological floating body comprises a bearing frame, acolumn, a buoy, a water-pushing propeller, microbial filler plates, an aeration cylinder, and a solar energy power supply system. The buoy supplies a floating force so that the bearing frame floats on water and the column is vertically inserted into sewage. The water-pushing propeller is arranged on the bottom end of the column. Multiple microbial filler plates are arranged on the periphery of the column in a peripheral array. The aeration cylinder and the column are concentric and enclose all microbial filler plates, and thus between the aeration cylinder and the microbial filler plates, multiple flow guide channels that surround the column in a peripheral array are formed. The water-pushing propeller pushes the sewage in the bottom layer into the flow guide channels; and the sewage is slowly pushed upwards along the corresponding flow guide channels and discharged to the upper layer. The biological floating body has the advantages of good sewage purification effect, high efficiency,and high automatic protection-management degree.

Description

technical field [0001] The invention belongs to the technical field of sewage purification, and in particular relates to a biological floating body for purifying sewage based on a biological method and a sewage purification method thereof. Background technique [0002] With the rapid development of science and technology and industry, the resulting pollution is becoming more and more serious, especially the pollution of water resources. Therefore, sewage purification treatment is urgent. Existing sewage treatment equipment has the following defects: [0003] 1. Large-scale treatment equipment is expensive and takes up a lot of space. It can only be used in fixed sewage tanks, and cannot be used for river water pollution control or lake water pollution control. The scope of application is limited; [0004] 2. The free mobility is poor. When it is used for centralized treatment of large-scale sewage, it needs to be densely distributed with more sewage treatment equipment, and...

AI Technical Summary

Problems solved by technology

[0003] 1. Large-scale treatment equipment is expensive and takes up a lot of space. It can only be used in fixed sewage tanks, and cannot be used for river water pollution control or lake water pollution control. The scope of application is limited;

[0004] 2. The free mobility is poor. When it is used for centralized treatment of large-scale sewage, it needs to be densely distributed with more sewage treatment equipment, and it needs to be managed manually at any time, and the input cost is high.
