A sewage plant tail water low-temperature biological regulation artificial wetland system and a method for treating sewage by using the same
By using hydroxyl-modified graphene oxide-coated volcanic rock filler in constructed wetland systems, the extracellular polymer aggregation properties are stimulated to form dense microbial aggregates, solving the problem of low wastewater treatment efficiency under low-temperature conditions and achieving a highly efficient low-temperature denitrification effect.

Abstract
The application belongs to the technical field of sewage treatment systems, and particularly relates to a sewage plant tail water low-temperature biological regulation and control artificial wetland system and a method for treating sewage by using the same. The sewage plant tail water low-temperature biological regulation and control artificial wetland system comprises a water inlet system, an artificial wetland pool body and a drainage pipeline. The water inlet system comprises a water inlet pipeline. The water inlet pipeline is laid at the bottom of a wetland filler area. The artificial wetland pool body is divided into a wetland filler area and a water collecting area by a perforated flower wall. Wetland plants are planted above the wetland filler area. The filler filled in the wetland filler area comprises hydroxyl modified graphene oxide coating volcanic rock and non-coating filler. The drainage pipeline is located in the water collecting area. The artificial wetland system provided by the application has good low-temperature nitrogen removal efficiency.
