Description
The present invention relates to a kind of naphthalene is that organic intermediate is produced the Processes and apparatus that in mother liquor, organism extracts, and belongs to chemical field.
Technical background: industrially take naphthalene as raw material, can synthesize a series of important naphthalenes for the production of dyestuff, medicine through unit operations such as sulfonation, nitrated, reduction, alkali fusions is organic intermediate.China is that production naphthalene is the big country of organic intermediate and dyestuff, is a large amount of foreign exchange of national extra earning every year, has obtained good economic benefit.But the production that while naphthalene is organic intermediate has also brought serious problem of environmental pollution, and has affected the Sustainable development of enterprise, naphthalene is the focus of paying close attention to for manufacturing enterprise, scientific research institution that is developed to of organic intermediate factory effluent improvement technology.Naphthalene is that organic intermediate factory effluent not only has the feature similar to general benzene series waste water, but also has some singularity, is mainly manifested in the following aspects:
1, pollutent water-soluble large, concentration is high, complicated component.Naphthalene is that naphthalene cycle compound in organic intermediate factory effluent is conventionally with hydrophilic sulfonic group, hydroxyl and amino, therefore it is water-soluble large.Organic concentration in waste water can reach several thousand to several ten thousand mg/litre, conventionally contains gas chromatography and isomer thereof, and contains a large amount of inorganic salt, and C O D is up to several ten thousand mg/litre.
2, acid (alkali) property is strong.Naphthalene is that organic intermediate factory effluent is generally strongly-acid or strong basicity, and p H value is large from 0～14 span scope.
3, color and luster is dark.It is brown to sorrel that naphthalene is that organic intermediate factory effluent is generally all, and colourity is 800～1200 times.
4, toxicity is large.Naphthalene series compound belongs to condensed-nuclei aromatics, and human body is had to larger harm.For example 1 one naphthylamines and 2 one naphthylamines have all proved strong carcinogen; Naphthols has a strong impulse effect to mucocutaneous, swallows or skin absorbs and has high toxicity.Therefore, this class waste water, if unprocessed direct discharge is by serious environment pollution, is detrimental to health.
5, readily biodegradable not.Due to the delocalization conjugated link(age) that naphthalene nucleus is comprised of 10 carbon atoms, structure quite stable, hard degradation.The B O D of most of waste water in this class waste water
5/ C O D is extremely low, and biochemical is poor, and toxic to microorganism, is difficult to process with general biochemical method.
Owing to having above-mentioned characteristic, naphthalene is that the waste water treatment of organic intermediate is one of global difficult problem.
