The invention discloses a novel coking wastewater ammonia nitrogen component removal device. The device comprises a filter cavity for filtering particle impurities in coking wastewater, an alkaline adjusting cavity for adjusting a PH value of the coking wastewater, a heating device for heating the coking wastewater to the certain temperature, an air stripping device for removing ammonia of the free state in the coking wastewater and an ammonia gas treating mechanism for absorbing gasified ammonia gas, wherein the filter cavity is provided with a water inlet pipe and a water outlet pipe which are communicated with the coking wastewater, and the alkaline adjusting cavity is communicated with the water outlet pipe on the filter cavity and communicated with an inlet of the heating device through a water pump. According to the novel coking wastewater ammonia nitrogen component removal device, high-concentration ammonia nitrogen in the coking wastewater can be rapidly removed, and the removal efficiency is high.
Description
technical field [0001] The invention relates to the technical field of coking wastewater treatment, in particular to a device for removing ammonia nitrogen components from coking wastewater. Background technique [0002] Coking wastewater is industrial wastewater containing volatile phenols, polycyclic aromatic hydrocarbons, and heterocyclic compounds such as oxygen, sulfur, and nitrogen produced during coking or coal gas high-temperature dry distillation, purification, and by-product recovery. It is a high-COD, high-ammonia nitrogen and very A kind of industrial organic wastewater that is difficult to treat. There are three main sources: one is the waste water produced in coal dry distillation and gas cooling, which is the main source of coking waste water; the other is the waste water produced in the process of gas purification, such as final cooling water of coal gas and crude benzene separation water; the third is Wastewater produced in refining processes such as tar an...
