Problems solved by technology

The existing sewage denitrification methods include A/O method, A2/O method and other processes. Specifically, firstly, aerobic microorganisms are used to nitrify sewage in an aerobic tank to realize COD, organic nitrogen, ammonia nitrogen, etc. in sewage. The degradation of pollutants, followed by denitrification treatment of sewage in anoxic tanks using anaerobic or facultative anaerobic microorganisms to conve...

Embodiment Construction

[0038] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0039] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The present invention relates to a sewage treatment device, which comprises a plurality of filler discs and fillers. The filler discs are sequentially stacked in the vertical direction, and the fillerdiscs can accommodate sewage to be treated. The fillers are arranged in the filler discs and are used for the growth of biological films. Sewage can flow through the filler discs in sequence from topto bottom by virtue of gravity, and can be in full contact with the biological films grown on the corresponding fillers in the process of flowing through the filler discs and form water films on thesurfaces of the biological films, so that the biological films grown on the fillers in the filler discs carry out biochemical treatment on the sewage in sequence. The sewage treatment device has the advantages of simple structure, easiness in implementation and high biochemical treatment efficiency. Moreover, a user does not need to additionally arrange a large number of power mechanisms to injectsewage into all the filler discs, and energy consumption is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sewage treatment device. Background technique [0002] At present, the problem of eutrophication in water bodies is serious, and excess nitrogen will affect people's normal water use. The existing sewage denitrification methods include A / O method, A2 / O method and other processes. Specifically, firstly, aerobic microorganisms are used to nitrify sewage in an aerobic tank to realize COD, organic nitrogen, ammonia nitrogen, etc. in sewage. The degradation of pollutants, followed by denitrification treatment of sewage in anoxic tanks using anaerobic or facultative anaerobic microorganisms to convert nitrate nitrogen and / or nitrite nitrogen produced in the nitrification stage into nitrogen gas, so as to finally achieve Denitrification of sewage and degradation of organic matter in sewage; however, the above methods generally have problems such as large area, high e...
