Problems solved by technology

[0015] It can be seen from the above that although the first and second technical measures can ensure the construction accuracy of filter plate pouring and filter head installation, the construction is very complicated and the accuracy is not easy to guarantee
At the same time, the construction period from the binding of the filter plate to the installation of the filter head is long, and the construction cost is relatively high
Article 3 Although the technical measures can effectively replace the damaged filter head, it is necessary to empty the entire tank body and then manually enter the closed space for operation. The operation is complicated and there are potential safety hazards
Article 4 Technical measures cannot fundamentally solve the problem of sludge accumulation

Abstract

The invention provides a biological aerated filter. According to the biological aerated filter, a filter material layer, a supporting plate and a filter brick layer are sequentially arranged in a filter body, wherein filter materials are arranged on the filter material layer; the supporting plate is used for supporting the filter materials in the filter material layer; the supporting plate is adjacent to the filter material layer; the filter brick layer is used for distributing water and air, consists of multiple tiled filter bricks and is adjacent to the supporting plate. In addition, the invention also provides a method for constructing the biological aerated filter.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an aerated biological filter for treating sewage. Background technique [0002] At present, biological aerated filters are often used in sewage treatment systems. Biological aerated filter, referred to as BAF, is a new type of biofilm sewage treatment process developed in Europe and the United States in the late 1980s. It has been greatly developed in the early 1990s. Nitrogen and phosphorus removal. This process has the functions of removing SS, COD, BOD, nitrification, nitrogen removal, phosphorus removal, and AOX (harmful substances). Biological aerated filter is a new process integrating biological oxidation and interception of suspended solids. [0003] At present, the biological aerated filter basically adopts the water and gas distribution system of the whole pouring filter plate + filter head, for example, in the attached figure 1 The biological aerated filter 100 in t...
