Ammonia-nitrogen wastewater treatment system

Abstract

A ammonia-nitrogen wastewater treatment system comprises a water collecting tank, an alkali liquor storing tank, a deaminizing tower and an absorption tower, and is characterized in that the water collecting tank is in pipe connection with the wastewater inlet of a primary condenser through a pump; the wastewater outlet of the primary condenser is in pipe connection with the wastewater inlet of a pipeline mixer; the alkali liquor storing tank is in pipe connection with the alkali liquor inlet of the pipeline mixer through a feed pump; the wastewater outlet of the pipeline mixer is in pipe connection with the wastewater inlet in the bottom end of a preheater; the wastewater outlet in the upper end of the preheater is in pipe connection with the wastewater inlet in the upper end of the deaminizing tower; the water outlet in the bottom end of the deaminizing tower is in pipe connection with the water inlet in the upper end of the preheater through a water pump; the water outlet in the lower end of the preheater is connected with a water drainage pipeline. According to the system, the ammonia-nitrogen removal rate is high, energy is saved, environment is protected, and waste heat and steam heat energy cyclic utilization is realized.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to an ammonia nitrogen waste water treatment system. Background technique [0002] Most of the ammonia nitrogen wastewater treatment in the prior art adopts the deammonization tower to remove ammonia, and the absorption tower absorbs ammonia gas, so as to meet the discharge standard, but the energy consumption of the whole system is high, and the waste heat cannot be effectively utilized, which needs to be improved. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides an ammonia nitrogen wastewater treatment method with high ammonia nitrogen removal rate, energy saving and environmental protection, and realizing recycling of waste heat and steam heat energy. [0004] In order to realize the purpose of the present invention, the following technical solutions are provided: a system for treating ammonia nitrogen wastewater, includ...
