Abstract

The invention discloses an MBBR (Moving Bed Biofilm Reactor) process for nano water treatment. The MBBR process comprises the step of removing organic matter, wherein for general secondary biologicaltreatment, when the BOD (Biochemical Oxygen Demand) of effluent is 25 mg / L, a two-stage fluidized bed process is generally adopted, for instance, a coagulation unit is arranged in front of a secondarysedimentation tank, or a one-stage fluidized bed process is used for chemical precipitation in first-stage treatment; when the BOD of effluent is 10 mg / L, a two-stage fluidized bed process is adopted, first-stage treatment of chemical precipitation or secondary sedimentation tank for coagulation sedimentation is required; for biological pretreatment using a fluidized bed process as an activated sludge process to deal with impact load, the one-stage fluidized bed process can be used. The MBBR process has a good decontamination effect, and can treat sewage more comprehensively.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an MBBR process for nanometer water treatment. Background technique [0002] "Water treatment" is the process of removing some harmful substances that are not needed for production and life in water through physical, chemical, and biological means. The process of water quality conditioning such as corrosion and scale inhibition. Since social production and life are closely related to water, the field of water treatment involves a wide range of applications and constitutes a huge industrial application. Sewage treatment generally includes three levels of treatment: the first level of treatment is to remove stones, sand and fat, iron ions, manganese ions, etc. contained in sewage through mechanical treatment, such as grille, sedimentation or air flotation; Treatment is biological treatment, in which pollutants in sewage are degraded and converted into sludge under the ac...
