Abstract

A tricyclic type synchronous carbon removal and denitrification biological reactor includes a reactor body and a water inlet pipe; the inner bottom plating of the reactor body is provided with an inverted circular truncated cone-shaped separator plate and a cylinder separator plate from the inside to the outside to divide the reactor cavity into a tricyclic type structure; the inverted circular truncated cone-shaped separator plate is used as an anaerobic zone; the region between the inverted circular truncated cone-shaped separator plate and the cylinder separator plate is used as an aerobic zone; the region between the cylinder separator plate and the side wall of the reactor body is used as an anoxic zone; the top of a three-phase separator is provided with a first gas vent; the aerobic zone is provided with an annular aeration device; the water outlet of the anoxic zone is equipped with a water outlet device; and the inlet end of the water inlet pipe is connected to the liquid outlet of a raw water adjusting pump, and the outlet end is let in the anaerobic zone. The invention has the beneficial effects that the reactor can remove carbon and nitrogen pollutants at the same time, and recover methane gas to turn waste into treasure; the reactor is provided with different zones to improve the hydromechanical properties and create the best conditions for microbe growth; and multi-level treatment of pollutants within the same reactor is achieved.

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...
