Abstract

The invention discloses a wastewater biological treatment reactor which comprises an influent water quick dilution detoxification region (1), a carbon source denitrification utilization (2), a gas lifting region (3), a spiral piston flow oxidizing region (4), a degassing region (8) and an upward flow channel (9) which are sequentially communicated, wherein the upward flow channel (9) is connected with the influent water quick dilution detoxification region (1). The wastewater biological treatment reactor also comprises a precipitation unit, wherein the precipitation unit is connected with the spiral piston flow oxidizing region (4), and comprises a pre-precipitation region (6), a precipitation region (5) and a sludge return region (7). The wastewater biological treatment reactor can remove organic matters and nitrogen in the toxic organic wastewater, has the advantages of simple equipment, convenient operating maintenance, high sludge concentration, high shock load resistance, favorable effluent water 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...
