Problems solved by technology

The jet flow used in this equipment will increase the crushing and abrasion of the resin during the mixing process. At the same time, the three-phase separator cannot separate the individual fine resin from the water, and the loss of the resin will be large.

Abstract

The invention relates to the field of wastewater treatment, in particular to a treatment method and treatment equipment for coking wastewater, which are used for removing COD (chemical oxygen demand) and chromaticity. The treatment equipment consists of a columnar reactor and magnetic separating equipment, the upper portion of the columnar reactor is a cylinder, the lower portion of the columnar reactor is a cone, one to five layers of stirring blades are arranged in the columnar reactor, and the magnetic separating equipment is arranged on the upper portion of the columnar reactor. The treatment method and the treatment equipment have the advantages that a treatment procedure is short, quantity of treated water is high, the equipment runs stably and reliably, and energy consumption and cost are low.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a coking wastewater treatment method and treatment equipment for removing COD and chroma. Background technique [0002] Coking wastewater is produced in the process of coking, gas purification and coking product recovery. It has complex components and many components. According to the coal quality and process, the water quality is very different. It contains more than 100 kinds of dissolved organic and inorganic substances. The wastewater is dark brown, mainly containing toxic and harmful substances such as phenol, cyanide, benzene, ammonia nitrogen, tar and sulfide, and also contains a small amount of naphthalene, pyridine, quinoline, indole, anthracene, carbazole and some substances in the form of salts Inorganic matter. [0003] Coking wastewater is a typical toxic and refractory industrial wastewater. At present, the domestic coking wastewater treatment system is mainly d...
