Abstract

The invention discloses an adjustable biological aerated filter. The adjustable biological aerated filter comprises a tank body, wherein a precise filter board, a filter material layer and a filter material layer adjusting control board are arranged on the tank body from bottom to top in sequence, so that the tank body is divided into a water distributing region below the precise filter board and a clear water region above the filter material layer adjusting control board; the water distributing region is communicated with a water inlet tube; a water outlet slot is arranged on the upper part of the clear water region; the water outlet slot is communicated with a water outlet tube; nanometer microcrystal filter material is placed in the filter material layer. The adjustable biological aerated filter can be used for controlling and adjusting the height of the filter material layer by adopting the filter material layer, so that the reaction region height can be adjusted according to inlet water ammonia-nitrogen change, and therefore, the adjustable biological aerated filter has stable outlet water quality.

Description

technical field [0001] The invention relates to a biological filter, in particular to an adjustable aerated biological filter. Background technique [0002] Biological aerated filter is a new biofilm sewage treatment process developed in Europe and America in the late 1980s. The process integrates biological oxidation and interception of suspended solids, with large volume load and hydraulic load, short hydraulic retention time, good effluent quality, and low operating costs. With the continuous deterioration of the ammonia nitrogen index of water source water quality and the increasing cost of water production, many tap water supply enterprises are facing tremendous pressure. Applying biological aerated filter to tap water supply enterprises will be the best solution to this problem. However, the existing biological aerated filter still has many defects and needs to be further improved. Contents of the invention [0003] The purpose of the present invention is to provi...
