Abstract

The invention discloses a suspension air exposure type biological carrier filler, and relates to the field of water treatment application. The filler comprises a water distribution main pipe, water distribution branch pipes, an umbrella-shaped combined fiber filler and a high-load combined filler. Tthe water distribution branch pipes are arranged on the water distribution main pipe; and the tail end of the lower part of the umbrella-shaped combined fiber filler is connected with the high-load combined filler. The water distribution main pipe transports sewage to each water distribution branchpipe, and the water distribution branch pipe on each layer uniformly distributes the sewage to the filler; the umbrella-shaped combined fiber filler is used as a support and provides biological attachment points, the high-load combined filler is fixed on the umbrella-shaped combined fiber filler and is vertically suspended, when water flows through the biological carrier, microorganisms in the water are attached and form a biological membrane, and pollutants in the water are degraded by utilizing oxygen in the air. According to the invention, through the combination of various carriers, the retention time of water flow on the filler and the effect of natural aeration are increased, the formation of a biological membrane is guaranteed, and the yield of sludge is reduced.

Description

technical field [0001] The invention relates to the application field of water treatment, in particular to a suspended air-exposed biological carrier filler, which is applied to an air-exposed biofilm reactor (AEB). Background technique [0002] Air-exposed biofilm reactor (AEB) is a new type of biofilm water treatment process. It uses the biofilm loaded on the carrier to degrade the pollutants in the wastewater. At the same time, it naturally absorbs oxygen in the air. No need for artificial aeration, saving energy and equipment costs. The performance of the filler is the main factor affecting the effect of AEB treatment. If the specific surface area of ​​the filler is large, the amount of saturated adsorbed water is large, and it is easy to form a film, the AEB treatment effect will be good, otherwise, the treatment effect will be poor. [0003] The biological carrier provides the attachment site for microorganisms, and the performance of the carrier directly affects the ...
