Atomization-evaporation high-ammonia-and-nitrogen wastewater treatment system

Abstract

The invention discloses an atomization-evaporation high-ammonia-and-nitrogen wastewater treatment system which comprises an atomized evaporator, wherein the atomized evaporator comprises a high-ammonia-and-nitrogen wastewater inlet pipe, a base and balance weight, and an electric auto-control device; the high-ammonia-and-nitrogen wastewater inlet pipe is connected with a water pump; a bracket is arranged on the base and balance weight; a rotating shaft is arranged at the top end of the bracket; a motor is arranged on the rotating shaft; a wind wheel is arranged on an output shaft of the motor; the high-ammonia-and-nitrogen wastewater inlet pipe is connected to the wind wheel through a core part of the bracket; a cable of the electric auto-control device is connected to the motor through the core part of the bracket. An atomization-evaporation system is used for treating high-ammonia-and-nitrogen wastewater; the atomization-evaporation high-ammonia-and-nitrogen wastewater treatment system is simple in structure and easy to control, cannot be affected by the weather and is high in ammonia-and-nitrogen removal rate.

Description

technical field [0001] The invention relates to a high ammonia nitrogen wastewater treatment system, in particular to an atomization evaporation high ammonia nitrogen wastewater treatment system. Background technique [0002] At present, high-concentration ammonia nitrogen wastewater (ammonia nitrogen concentration greater than 200mg / L) produced by the coking industry, high-tech material industry, and chemical industry has become a difficult problem in the wastewater treatment industry. Treatment methods for high-concentration ammonia nitrogen wastewater usually include physical and chemical methods, biological denitrification methods, combined physical and chemical and biochemical methods, among which physical and chemical methods are mainly divided into stripping method (steam stripping), ammonia distillation method, MAP (struvite) precipitation method, and chemical oxidation method. The stripping and gas stripping method is to pass the gas (carrier gas) into the water to...
