Phenol-ammonium waste water treatment device

Abstract

The invention provides a phenol-ammonium waste water treatment device. The phenol-ammonium waste water treatment device comprises section-I pretreatment, section-II biochemical treatment and section-III further treatment; the section-I pretreatment includes gravity oil separation, oil-water separation, ceramic filter, ammonium steaming and extraction dephenolization process; the section-II biological treatment include catalytic oxidation, air floatation, hydrolysis acidification, A / O biochemical treatment, coagulating sedimentation and mechanical filter process; the section-III advanced treatment includes ozone catalytic oxidation, active carbon filter, ultra-filtration membrane filter and RO reverse-osmosis process, the section-I pretreatment, the section-II biochemical treatment and the section-III further treatment are controlled by a PLC control system, so that the automatic operation of the whole set of system is realized. The phenol-ammonium waste water treatment device innovatively solves the difficulty for treating the phenol-ammonium-containing waste water in the field of coal gas chemical industry and also has the characteristics of recyclability, compact structure, high investment return rate, stability and reliability in operation, high automation degree and the like.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a phenol ammonia wastewater treatment device. Background technique [0002] The rapid development of the chemical industry has also brought serious pollution to the environment on which human beings depend. The treatment of wastewater containing phenol and ammonia is a problem that is generally valued at home and abroad. At present, there are many methods for treating phenol and ammonia in wastewater. In summary, there are mainly physical, chemical and biological methods. These methods are still in the initial stage of the laboratory and cannot effectively solve practical problems. In addition, it is difficult to achieve the expected purpose when a single method is applied to specific industrial wastewater, especially the emergence of new coal chemical technology, the process is more complicated, and the wastewater problems caused by the new process are more promine...
