Abstract

The invention discloses a wastewater ammonia nitrogen blow-off treatment reaction device which comprises a shell, wherein a gas water separation layer, a water distribution device, an umbrella-shaped water shield and a gas distribution device are distributed in the shell at intervals from top to bottom in sequence; the shell is divided into an upper chamber and a lower chamber by the umbrella-shaped water shield; a drain pipe is arranged on the shell at the bottom of the upper chamber; the water distribution device consists of a water inlet pipe, a gas inlet pipe and a double-fluid spray nozzle, wherein the water inlet pipe and the gas inlet pipe are communicated; and the communication part of the water inlet pipe and the gas inlet pipe is provided with the downward double-fluid spray nozzle to form a three-way structure, so that gas-liquid waste caused by mixing gas and liquid by utilizing a packing layer can be effectively avoided, channeling and wall flow phenomena can be effectively prevented, and the stability of ammonia nitrogen blow-off treatment is improved.

Description

technical field

[0001] The invention relates to waste water treatment equipment in the field of environmental protection, in particular to a waste water ammonia nitrogen stripping treatment reaction device. Background technique

[0002] With the vigorous development of petrochemical, pharmaceutical, pesticide and fine chemical industries, a large amount of high-concentration ammonia nitrogen wastewater is produced in the process of chemical production. If such wastewater is discharged directly without treatment, it will cause great damage to the water environment.

[0003] At present, the treatment methods for high-concentration industrial ammonia-nitrogen wastewater mainly include: stripping method, steam stripping method, ammonia distillation method, and chemical precipitation method. Among them, the chemical precipitation method has not yet been applied in large-scale engineering due to its high operating cost and complicated operation; the three methods of air stripping,...
