Problems solved by technology
With the improvement of water pollutant discharge standards, the original sewage treatment facilities can no longer meet the discharge requirements at the current stage, and a large number of urban sewage treatment plants are facing technical requirements for standard upgrading and transformation
[0003] The traditional sewage biological treatment process is mainly based on the activated sludge with microbial suspension growth. Although this method has many advantages and is widely used in the field of sewage treatment, it also has many defects, especially in the upgrading of urban sewage treatment plants. Retrofit and the problem that effluent ammonia nitrogen and TN are not up to standard under low temperature conditions

Abstract
The invention discloses an embedded carrier filler circulating device, a sewage treatment system and a sewage treatment method.The embedded carrier filler circulating device comprises a gas conveying pipeline, a gas stripping pipe and a water tank, and the gas conveying pipeline is used for being connected with a gas source; the gas stripping pipe is provided with a first filler inlet, a first filler outlet and a gas inlet, the first filler inlet is formed above the first filler outlet, the gas inlet is located between the first filler inlet and the first filler outlet in the vertical direction, and the gas inlet is connected with the gas conveying pipeline; the upper end of the water tank is open, a second filler inlet is formed in the tank bottom of the water tank, the gas stripping pipe penetrates through the second filler inlet and is connected with the tank bottom of the water tank in a sealed mode, and a second filler outlet is formed in the first tank wall of the water tank. The embedded carrier filler circulating device provided by the embodiment of the invention has the advantages that the embedded carrier filler circulating efficiency is high, the embedded carrier filler is not easy to damage, and the like.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an embedding carrier filler circulation device, a sewage treatment system and a sewage treatment method. Background technique [0002] At this stage, the mainstream process of urban sewage treatment in my country is still dominated by activated sludge method and biofilm method. With the improvement of water pollutant discharge standards, the original sewage treatment facilities can no longer meet the discharge requirements at the current stage, and a large number of urban sewage treatment plants are facing the technical needs of standard upgrading and transformation. [0003] The traditional sewage biological treatment process is mainly based on the activated sludge with microbial suspension growth. Although this method has many advantages and is widely used in the field of sewage treatment, it also has many defects, especially in the upgrading of urban sewage treatment ...
