Problems solved by technology

The following problems will arise during the construction and operation of the system: civil engineering and installation are complicated, the construction period is long, and the construction accuracy is not easy to guarantee; a 1-meter-high filter chamber needs to be installed below the filter plate for the installation of air distribution pipelines and daily maintenance. The filter chamber occupies a large volume of the pool but does not play a role in removing pollutants, which is a waste volume
Since the biological aerated filter needs continuous aeration during operation, the current filter bricks cannot achieve good aeration and at the same time achieve downward flow of water filtration

Abstract

The invention provides a filter brick for aerated biological filter, the filter brick includes a first chamber extending from the bottom to the top of the filter brick, the cross-sectional area of ​​which gradually decreases from bottom to top; the first chamber The side of the filter brick is an orifice plate with multiple openings. The filter brick is provided with a partition plate between the middle of the orifice plate and the top wall. The orifice part, the top wall is divided into the first top wall part and the second top wall part at the junction with the partition plate; wherein, the lower orifice part, the side wall of the filter brick, the first top wall part and the partition plate form In the second chamber, the first top wall part is provided with openings, and the first top wall part is adjacent to the side wall; the upper hole plate part, the second top wall part and the partition plate form the third chamber, and the second top wall part The wall is provided with openings, and the partition plate separates the second chamber from the third chamber. The present invention also provides an aerated biological filter adopting the filter brick.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a filter brick used for an aerated biological filter and an aerated biological filter using the filter brick. Background technique [0002] Biological aerated filter, referred to as BAF ((Biological Aerated Filter), is a new type of biofilm sewage treatment process developed in Europe and the United States in the late 1980s. It was greatly developed in the early 1990s, with a maximum scale of hundreds of thousands of tons. Every day, and developed to be able to remove nitrogen and phosphorus. This process has the functions of removing SS (suspended solids), COD (chemical oxygen demand), BOD (biochemical oxygen demand), nitrification, denitrification, phosphorus removal, removal of AOX (hazardous substances ), the biological aerated filter is a new process that integrates biological oxidation and interception of suspended solids. [0003] The biological aerated filter in the prior...
