Embodiment 1

[0039] Taking the treatment of coking wastewater as an example, the system for treating coking wastewater using granular carbon in a renewable manner includes an adsorption tower 2, and the outlet on the upper part of the adsorption tower 2 is connected to a clear water pool;

[0040] The lower part of the adsorption tower 2 has a coking wastewater inlet, which leads to the raw wastewater pool;

[0041] The outlet at the lower part of the adsorption tower 2 is connected with a waste carbon washing tank 4, and an outlet at the lower part of the waste carbon washing tank 4 is connected with the raw waste water pool;

[0042] Another outlet waste carbon feed tank 7 at the lower part of the waste charcoal washing tank 4 is connected, and there is a dehydration screw conveying device 8 below the outlet of the waste charcoal feed tank 7 to transport the waste charcoal to the multi-stage regeneration furnace 9;

[0043] The outlet at the bottom of the multi-stage regeneration furnace...

Abstract

The invention belongs to the technical field of waste water treatment, and in particular relates to a method for improving the quality of waste water to meet standards based on activated carbon regenerable treatment, and also relates to a system used in the above method, and also relates to the system used. The method for treating waste water in a reproducible manner by using activated carbon in the present invention comprises the following steps: (1) treating waste water with granular carbon adsorption; (2) regenerating the granular carbon adsorbed by waste water. The invention utilizes the rich pore size on the surface of the granular carbon to effectively adsorb various substances in the wastewater, reducing the content of COD, volatile phenol, chroma, cyanide, etc., and the activated carbon is reproducible, which can realize fully automatic operation and clean production during the treatment process , The purpose of increasing efficiency and reducing costs.
