Abstract

The invention discloses a wastewater biological treatment reactor, which comprises an inflow rapid dilution detoxification zone (1), a carbon source denitrification utilization zone (2), an airflow lifting zone (3), and a spiral plug flow oxidation zone ( 4), a degassing zone (8) and an upflow channel (9), the upflow channel (9) is connected to the influent rapid dilution detoxification zone (1), and the wastewater biological treatment reactor also includes a sedimentation The unit is connected with the spiral plug flow oxidation zone (4), and the sedimentation unit includes a pre-sedimentation zone (6), a sedimentation zone (5) and a sludge return zone (7). The waste water biological treatment reactor of the invention can realize the removal of organic matter and nitrogen in toxic organic waste water, has simple equipment, convenient operation and maintenance, high sludge concentration, strong impact load resistance, good effluent quality and low energy consumption.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a waste water biological treatment reactor. Background technique [0002] In recent years, industrial wastewater discharge standards have been continuously improved. In addition to the reduction of COD and other discharge limits, indicators such as ammonia nitrogen and total nitrogen have also been included in many industrial wastewater discharge standards. Therefore, there is a significant demand for treatment technologies that simultaneously remove organic matter and nitrogen in wastewater. Biological treatment technology is a common technology for removing biodegradable organic matter and nitrogen in wastewater. It has the advantages of low investment and low operating costs, and has been widely used in urban domestic sewage treatment. Most of the wastewater discharged in the chemical production process is high-concentration toxic organic wastewater. Due to the toxic org...
