Abstract
The invention discloses a coking wastewater recycling method and belongs to the technical field of environmental protection treatment for metallurgy systems. At present, coking wastewater is treated with biochemical methods, organic and harmful ingredients such as phenol, benzene and the like in the wastewater are decomposed through activated sludge, but the requirement for the harmful ingredients in the wastewater is relatively strict, the activated sludge is poisoned to death and loses the decomposition effect easily due to the higher content of the harmful ingredients, the running cost is higher, and the disposable equipment investment is high. The technical scheme is as follows: directly delivering the coking wastewater to an ingredient plant of a sintering machine through a water pump and a pipeline, adding 7-8% of the coking wastewater to to-be-sintered ingredients to adjust and control the content of moisture so as to meet the ingredient requirement, and burning organic matters in the coking wastewater in the follow-up sintering process to recycle the coking wastewater. The method has the advantages as follows: the investment is low, the treatment capacity is high, the coking wastewater can be treated relatively thoroughly, no secondary wastewater is produced, and the method is the best in existing treatment methods and technologies.
Description
Technical field
The invention belongs to metallurgical system environment protection treating technical field, more specifically a kind of coke-oven waste water recoverying and utilizing method.
Background technology
At present biochemical process process is adopted to coke-oven waste water, by organic objectionable constituent such as the phenol in active sludge decomposition sewage and benzene, but require comparatively strict to the objectionable constituent in sewage, the higher active sludge that easily causes of content is poisoned to death and loses Decomposition, working cost is higher, and within 1 year, need hundreds of thousands of, disposable apparatus drops into unit up to a million, and sewage discharge is not up to standard, the effluent charge of turning over nearly 1,000,000 yuan of environmental administration are every year used.
Summary of the invention
For overcoming above-mentioned shortcoming, the object of the invention is to invent a kind of coke-oven waste water recoverying and utilizing method.Its technical scheme is: batching field coke-oven waste water being delivered directly to sinter machine by water pump and pipe, road, the coke-oven waste water of 7-8% is added with the content of regulable control moisture in the batching in ore deposit to be sintered, reach dispensing requirements, the organism in coke-oven waste water is burned the recycling reaching coke-oven waste water in sintering process subsequently.The advantage of this invention is: the method less investment, more thorough to coke-oven waste water process, due to objectionable impurities in coke-oven waste water if the material major part such as COD, benzene class, phenols, HCN, H2S, NH3 is organism, primarily of C, H, 0 three kinds elementary composition, water and carbonic acid gas is generated after burning, nontoxic.Treatment capacity is large, produces without waste water, and the invention of the method is successfully by the new way of developing coke-oven waste water treatment process, and will produce the large economic benefit of saddle, social benefit and environmental benefit are best in existing treatment process technique, on agglomerate finished product without impact.
Embodiment
Coke-oven waste water is delivered directly to the batching field of sinter machine by water pump and pipeline, the coke-oven waste water of 7 ~ 8% is added with the content of regulable control moisture in the batching in ore deposit to be sintered, reach dispensing requirements, the organism in coke-oven waste water is burned the recycling reaching coke-oven waste water in sintering process subsequently.
Claims (1)
1. a coke-oven waste water recoverying and utilizing method, it is characterized in that: batching field coke-oven waste water being delivered directly to sinter machine by water pump and pipeline, the coke-oven waste water of 7 ~ 8% is added with the content of regulable control moisture in the batching in ore deposit to be sintered, reach dispensing requirements, the organism in coke-oven waste water is burned the recycling reaching coke-oven waste water in sintering process subsequently.
