AI Technical Summary

Technical Problem

The prior art has poor effect when reducing the ammonia concentration in water containing ammonia, resulting in insufficient removal of ammonia.

Method used

An ammonia treatment system is designed, including an absorption tower, an ammonia component removal part, an ammonia water introduction pipeline and a treatment water supply pipeline. Ammonia gas is in contact with water in the absorption tower to form ammonia water. The ammonia water is processed by an ammonia component removal part, and then supplied to the sprinkler part for use after the processed water is generated.

Benefits of technology

Through this system, the ammonia can be fully removed from the water containing ammonia, the ammonia concentration can be reduced, and the treatment water can be effectively utilized, the use of external water can be reduced, and energy saving.

Abstract

An ammonia treatment system is provided with: an absorption tower having a housing, a gas introduction unit for introducing ammonia gas containing ammonia into the housing, a water spray unit for generating ammonia water by spraying water from the upper part in the housing to absorb ammonia, and a water discharge unit for discharging ammonia water from the lower part of the housing; an ammonia component removal unit which is provided outside the absorption tower and which removes an ammonia component contained in the ammonia water to generate treated water; an ammonia water introduction line that introduces the ammonia water discharged from the water discharge unit to the ammonia component removal unit; and a first treated water supply line that supplies the treated water generated by the ammonia component removal unit to the water sprinkling unit.
