Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment devices, in particular to a multi-stage enhanced ammonia nitrogen stripping reaction device. Background Art

[0002] The multi-stage enhanced ammonia nitrogen stripping reaction unit is an environmental protection equipment specially designed for treating high ammonia nitrogen wastewater. The unit effectively removes the ammonia nitrogen components in the wastewater through multi-stage stripping and enhanced mass transfer technology to achieve the purpose of purifying water quality.

[0003] The working principle of the multi-stage enhanced ammonia nitrogen stripping reaction device is based on the gas-liquid phase equilibrium and mass transfer rate theory. There are usually multi-stage stripping units inside the device. The wastewater is lifted to the top of the reaction tower by a lifting water pump, and then the wastewater flows through the stripping units at each stage under the action of gravity. Under alkaline conditions, the ammonia nitrogen in the wastewater (mainly in the form of ammonium ions NH4+) is converted into free ammonia (NH3), and the free ammonia is transferred from the wastewater to the gas phase through the stripping effect of air or steam, thereby realizing the removal of ammonia nitrogen.

[0004] The device usually consists of a pretreatment unit, a multi-stage stripping tower, a packing layer, a gas distribution device, an absorption tower and a control system. Among them, the multi-stage stripping tower is the core component of the device. Through the multi-stage structure design, the contact area and contact time between wastewater and air are increased, thereby enhancing the removal effect of ammonia nitrogen.

[0005] However, traditional ammonia nitrogen stripping devices may be affected by factors such as wastewater concentration, pH value, temperature, and gas-liquid ratio, resulting in limited stripping efficiency. When the ammonia nitrogen concentration in the wastewater is high or the pH value is low, the stripping efficiency will be significantly reduced. Utility Model Content
