Abstract
The invention discloses a treatment method of coking wastewater. The treatment method comprises the following treatment steps: (1) pre-treating the coking wastewater and filtering by natural sea sand filtering material; (2) adding polyamide resin to the coking wastewater filtered by the natural sea sand filtering material, wherein the weight of the polyamide resin is 5.2-6.5wt% of the weight of the coking wastewater; (3) slowly stirring the wastewater for 40-80min; (4) separating the polyamide resin from the wastewater after the stirring step; (5) adding graphite powder into the wastewater after the separating step, wherein the weight of the graphite powder accounts for 3.3-3.7wt% of the weight of the coking wastewater; and (6) taking supernatant after standing for 6h, and the supernatant is treated coking wastewater. After the coking wastewater is treated by the method, the phenol content is decreased from 749mg/L to 17-24mg/L and the xylenol content is decreased from 232mg/L to 12-19mg/L.
Description
Technical field
The present invention relates to a kind for the treatment of process of waste water, particularly relate to a kind for the treatment of process of coking chemical waste water.
Background technology
Coking chemical waste water is coal chemical enterprise when producing the product such as coke, coal gas, the waste water such as cooling, the washing of generation.In these waste water, toxic substance and difficult decomposed substance are very many, such as phenol, xylenol, ammonia nitriding compound etc.These materials have formed the main source of coking chemical waste water jointly.If effectively reduce phenol wherein and the content of xylenol, it is the difficult problem of research at present.Usually industry is used biological process degraded and absorb objectionable impurities wherein, and the chemical method effect produces little effect.The biological process cost is higher, has restricted its a large amount of application development.
Summary of the invention
The technical problem solved: phenol and the higher problem of xylenol content in coking chemical waste water.
Technical scheme: the invention discloses a kind for the treatment of process of coking chemical waste water, treatment step is as follows: (1) coking chemical waste water carries out pre-treatment, by the natural sea sand filtrate; (2) will add polyamide resin in the coking chemical waste water by the natural sea sand filtrate, 5.2wt%～6.5wt% that the weight of polyamide resin is coking chemical waste water weight; (3) waste water is slowly stirred, the stirring duration is 40～80min; (4) stirring separates polyamide resin after finishing with waste water; (5) separate in backward waste water and add Graphite Powder 99,3.3wt%～3.7wt% that the weight of Graphite Powder 99 is coking chemical waste water weight; (6) get supernatant liquor after standing 6h, supernatant liquor is coking chemical waste water after processing.The order number of natural sea sand filtrate is preferably 300～400 orders.The order number of polyamide resin is preferably 200～300 orders.The weight of polyamide resin is preferably the 6.5wt% of coking chemical waste water weight.The weight of Graphite Powder 99 is preferably the 3.7wt% of coking chemical waste water weight.
Beneficial effect: the coking chemical waste water that disposal methods of the present invention is crossed, phenol content is down to 17mg/L～24mg/L from 749mg/L, and xylenol content is down to 12mg/L～19mg/L from 232mg/L.Effect with phenol and xylenol content in outstanding reduction coking chemical waste water.
