Abstract

The invention provides production equipment of active coke for phenol ammonia wastewater treatment and a treatment method of the equipment. The equipment comprises a material inlet unit, a riser reactor, a charcoal burner, an active coke production device, a separation unit and a wastewater treatment unit; the riser reactor extends upwards into the separation unit, a solid outlet of the separationunit is connected with the charcoal burner, a gas outlet of the separation unit is connected with the riser reactor, and a wastewater outlet of the separation unit is connected with the wastewater treatment unit; and a first outlet of the charcoal burner is connected with the riser reactor, and the charcoal burner, the active coke production device and the wastewater treatment unit are sequentially connected. According to the equipment provided by the invention, the active coke production device is added on the basis of pyrolysis of pulverized coal, and the prepared activated coke is used foron-line treatment of phenol ammonia wastewater generated by the pyrolysis of the pulverized coal, so that a production process of the activated coke is simplified, the phenol ammonia wastewater can be effectively treated, and difficulty of wastewater treatment is reduced; and at the same time, the activated coke after adsorption can be regenerated on line for recycling.

Description

technical field [0001] The invention belongs to the technical field of coal chemical industry, and relates to an active coke production device for treating phenol ammonia wastewater and a treatment method thereof. Background technique [0002] With the increasingly serious problems of energy shortage and environmental pollution, it has become a consensus to develop clean and efficient technologies for utilizing chemical raw materials. As coal is a non-renewable fossil energy, improving the utilization efficiency of coal resources, developing and promoting clean coal technology has increasingly become a research hotspot. [0003] Coal pyrolysis is one of the important ways of resource utilization of coal at present, and increasing the added value of corresponding products is an effective way to increase the value of coal utilization. Various chemical products such as tar and gas can be prepared from coal, and a large amount of powdered coke is often produced at the same time...
