Example Embodiment

[0109] The ASBF invention is further explained in conjunction with the specific examples shown in the drawings. This explanation is only used to demonstrate the ASBF invention, not to limit the scope of the ASBF invention.

[0110] Such as Figure 1-Figure 6 As shown, this is a view of the unique process device used to purify sewage treatment in the ASBF invention. The present invention is a rectangular parallelepiped device. According to the scale and size requirements of the treatment plant, the housing 1 can be made of different building materials. For example, it can be made of steel plate, stainless steel plate, PVC, FRP, prefabricated cement board or other non-corrosive materials, and the rectangular parallelepiped facilities can be placed on the ground or underground cement foundation of the construction site, or be buried according to the actual situation. The rectangular parallelepiped facilities.

[0111] Specific as figure 1 , figure 2 , Image 6 As shown, the present...

Abstract

The invention discloses an active sludge sewage treatment facility, which consists of an anoxic reaction chamber, an aerobic reaction chamber and a filtering and clarifying chamber communicated in sequence. Sewage is mixed with a large amount of active sludge reflowing from the filtering and clarifying chamber and flows into the aerobic reaction chamber after entering the anoxic reaction chamber.In the aerobic reaction chamber, a large quantity of bacteria, epiphytes and microorganisms are metabolized into suspended objects under the actions of aeration, oxidation and decomposition. The sludge inlet of the filtering and clarifying chamber is used for controlling the sludge current flowing in from the aerobic reaction chamber. The bottom of the filtering and clarifying chamber is providedwith a sludge outlet which is used for making the sludge reflow into the anoxic reaction chamber and be mixed with sewage entering the anoxic reaction chamber for starting a new cycle of treatment procedure which is the same as the process. Purified water flows out of a purified water overflowing weir on the top of the filtering and clarifying chamber. The active sludge sewage treatment facility has a compact structure, a small occupied area and good energy saving and emission reduction effects, and can be widely applied to various sewage treatment industries, in particular to a large quantity of middle-small cities, development areas, dispersive towns, tourist attractions and the like.

Description

technical field [0001] The ASBF of the present invention is used in sewage treatment, specifically, it is a complete set of facilities and a method for improving sewage treatment effect technical background [0002] 99% of the existing water reserves on the earth are seawater and polar ice that are not suitable for human use, and the remaining 1% is mostly below 800 meters. The water in rivers and lakes that people rely on for survival only accounts for 0.01% of the total. Global freshwater resources are not only in short supply but also extremely uneven in regional distribution. [0003] Due to China's unprecedented rapid development and insufficient awareness of environmental protection, coupled with the large population's large demand for water resources and sewage discharge, China is currently facing a very severe shortage of water resources. Zhongyuan is a country with severe water shortage. The total fresh water resources are 2.8 trillion cubic meters, accounting for ...
