Abstract

A three-ring synchronous decarbonization and denitrification bioreactor, comprising a reactor body and a water inlet pipe, the inner bottom plate of the reactor body is arranged with an inverted truncated truncated baffle plate and a cylindrical baffle plate from the inside to the outside to separate the inner cavity of the reactor body into two parts. Three-ring structure, the inner cavity of the inverted truncated truncated baffle plate is used as an anaerobic zone, the area between the inverted truncated truncated truncated baffle plate and the cylindrical baffle plate is used as an aerobic zone, and the space between the cylindrical baffle plate and the side wall of the reactor body is used as an aerobic zone. The top of the three-phase separator is provided with a first exhaust hole; the aerobic zone is provided with an annular aeration device; the water outlet of the anoxic zone is equipped with a water outlet; the water inlet end of the water inlet pipe is connected to The liquid outlet of the raw water regulating pump, and the outlet end leads to the anaerobic zone. The beneficial effects of the invention are: simultaneous removal of carbon and nitrogen pollutants; methane gas can be recovered to realize turning waste into treasure; different zones are arranged in the reactor to improve the hydrodynamic properties and create optimal conditions for the growth of functional microorganisms; the same The multi-level treatment of pollutants is realized in the reactor.

Description

technical field [0001] The invention relates to a three-ring synchronous carbon and nitrogen removal bioreactor, which belongs to the field of wastewater biological treatment. Background technique [0002] In recent years, with the development of the economy, a large amount of wastewater rich in organic matter and nitrogen pollutants, such as chemical wastewater, livestock and poultry wastewater, and agricultural and sideline product processing wastewater, has been discharged into water bodies, causing serious water pollution problems. [0003] However, the existing wastewater treatment processes mostly focus on the removal of single pollutants such as organic matter, and seldom consider the removal of organic matter and nitrogen pollutants in wastewater at the same time, resulting in complex process flow, high energy consumption, and large floor space. question. In view of the current situation of social development in our country, it is imminent to find a process with sta...
