Description
Technical field
The present invention relates to the processing method of a kind of coke-oven waste water, belong to the field of waste water treatment in environmental conservation.
Background technology
Along with the fast development of China market economy, China's coking industry is also into a quick period of expansion.1991
Year, the coke output of China leapt to No. 1 in the world the most, and coke annual production in 1994 is more than 100,000,000 tons, and within 2000, China Coke goes out
Mouth amount accounts for the 60% of world's coke volume of trade, becomes coke production state the biggest in the world.End to 2015, China Coke year
Yield more than 500,000,000 tons, has made huge contribution for China's national economy sustained and rapid development." 12 " period, coking
The great historic task that industry faces adjusts structure, transforms the mode of development, this is the needs of national strategy transition, is that economy can
The needs of sustainable development, are the needs of low-carbon (LC) social development.Therefore, the pollution of the coking industry three wastes and governing problem, become
It it is that a pendulum is in face of people, it is impossible to the critical problem of ignorance.
The source of coke-oven waste water is mainly gasworks and coking plant, and these factories are at gas purification and process of coking and right
Heavy chemicals carry out refined during can give off the substantial amounts of waste water containing harmful toxic matters such as cyanogen, phenol, ammonia nitrogens, and wherein ammonia still process
During produce remained ammonia be the largest source.Remained ammonia replenishment cycles ammonia is remaining, cyclic ammonia water the storage discharged
It is stored in ammonia storage tank.Remained ammonia is a kind of phenol water for essence, but wherein ammon amount is the highest.Containing many in remained ammonia
Planting objectionable impurities, such as coal tar, Blausure (German), ammonia and hydrogen sulfide etc., the most a small amount of germanium-containing compound, these materials are to ring
The harm in border is extremely serious.Remained ammonia mostly come from shove charge dry distillation of coal process generate water, shove charge coal surface condensation water with
And discharge circulates oxygen water pump and is added to inhale the technique waste water in gas piping.Once remained ammonia neutralizes other at storage tank
The technique waste water mixing in source will generate more intractable mixing remained ammonia.Reduce the ammonia content in mixing remained ammonia general
The technical process used is oil removing, goes the technological means such as phenol, desulfurization, ammonia still process, and these technological means are used in combination sometimes, to reach
To more preferable treatment effect.
Coke-oven waste water is a kind of industrial wastewater being typically difficult to and degrading, and wherein contains the heterocyclic compound of phenol, oxygen, nitrogen, sulfur
Things etc. are difficult to the organic substance decomposed, and benzene class and phenolic compound in coke-oven waste water are prone to degraded, imidazoles naphthalene, pyrroles, furan
Etc. belonging to degradable type organic, pyridine, biphenyl, carbazole etc. then belong to the Organic substance of difficult degradation.Harmful inorganic matter therein
Having serious toxicity with compound on organism, can cause protein coagulating, cell loses activity, and ultimately results in tissue and occurs
Damage or necrosis, be finally developed to the state of systemic toxicity profiles.The difficulty additionally, the polycyclic aromatic hydrocarbon biology in coke-oven waste water is not only degraded
Degree is big, but also is a kind of carcinogen.So, discharge coke-oven waste water severe contaminations local environment in a large number, and to human body
Health also have serious impact.Processing coke-oven waste water traditional method is divided into two parts, Part I to be pretreatment, Part II
It it is biological denitrificaion after-treatment.But after this processing method, the index such as ammonia nitrogen in efflux wastewater, cyanide is difficult to
Up to standard.To this end, a large amount of scholars further investigate for above-mentioned situation, analyze multiple treatment technology.
At present, the Waste Water Treatment of domestic coke-oven plant mainly uses coagulation and two stage treatment, uses tertiary treatment
Also seldom.Coagulation refers to recycle pollutant from high-concentration sewage, and its technique includes that ammonia dephenolize, ammonia steam
Evaporate, whole cold water decyanation etc..Two stage treatment refers mainly to coke-oven waste water harmless treatment, based on activated sludge process, also includes strengthening
Biologic treating technique such as Biology-iron etc..Three grades of advanced treating refer to when the water after biological treatment still can not reach discharge standard or
The deep purifying again that used when requiring reusing sewage, its main technique has an oxidation pond process, chemical coagulation and precipitation, Filtration,
Active carbon adsorption etc..
Most domestic coke-oven plant all uses advantage of lower cost, the bioremediation of technology maturation is at coke-oven waste water
The main body of science and engineering skill.According to statistical result, the disposal status of current domestic coke-oven waste water is: the waste water quality of each coke-oven plant has relatively
Big difference, the coke-oven waste water COD after ammonia still process processes is general the most still at 1000 ~ 3000mg/L, and minority is less than 1000mg/L, but have
Higher than 5000mg/L.The prevailing technology that domestic coke-oven waste water processes is pretreatment biochemical treatment post processing, and major part is biological
Process and use A/O denitrification process, while organics removal, remove the ammonia nitrogen in waste water.Pretreatment many employings oil removing measure with
Reduce the oils concentration in waste water, create favorable conditions for growth of microorganism.Post processing many employings coagulating sedimentation is final to reduce
The float of water outlet and Organic substance, minority coke-oven plant uses the materialization technology such as carbon filter, zeolite filtration or oxidation so that final outflow water
Water quality is substantially better than common solid-liquid separation technique, but processing cost is high.Therefore, along with expanding economy and country are to efforts at environmental protection
The raising required, without dilution at water, resistance to water quality impact capacity is strong, operating cost is low efficient, practical, stable coke-oven waste water
Reason technology is still one of the study hotspot of current field of water treatment and the hope of manufacturing enterprise.
At present, in existing process coke-oven waste water generally there is processing cost height, process effect in the method for Nitro-phenols
The most undesirable, Technology complicated difficult is with shortcomings such as popularizations.Therefore, it is necessary to break away from existing treatment technology thinking, hew out
Process the new way of the coke-oven waste water containing Nitro-phenols, and then develop nitro phenolate in the coke-oven waste water of a kind of new type
The treatment technology of compound.
