Description
Technical field
The present invention relates to method of wastewater treatment, in particular it relates to a kind of method for preparing fertilizer by allantoin production waste water
And fertilizer.
Background technology
Allantoin, English name Allantion, chemical name Allantio, it is a kind of weight
The fine chemical product wanted, purposes are extremely wide.Allantoin, which has, promotes skin epithelial cell growth, wound healing, analgesic, soft
Change the physiological function such as keratoprotein, and it is nontoxic, non-stimulated, without anaphylaxis, have lucifuge, sterilization and anticorrosion, antioxidation, can make
Skin keeps moisture content, moistens and soft, thus is widely used in medicine and Cosmetic Manufacture.In addition, allantoin also has thorn
Swash the function of biological growth, plant growth regulator can be used as in agricultural production, there is solid fruit, accelerate the ripening, increase production and other effects.
Natural allantoin is present in excreta and some plants of some animals, can be carried using certain technique
Take, for example, Chinese patent CN1958575A and CN1861581A are reported from Chinese yam and are extracted allantoin in saline cistanche respectively,
But because content it is low and involved by processing step complexity the problems such as, almost without practical value for the preparation of allantoin.Therefore,
Allantoin is prepared using chemical synthesis process both at home and abroad at present.
Existing industrialized production allantoin method, mainly using glyoxal nitric acid oxidation method.Glyoxal method is in two steps
Carry out, it is glyoxalic acid that the first step, which relate to glyoxal through nitric acid oxidation, and second step is under the nitric acid effect of carbon monoxide-olefin polymeric
Glyoxalic acid and urea condensation generation allantoin, yield typically about 40%.As can be seen here, glyoxal nitric acid oxidation method production allantoin
During, substantial amounts of nitric acid is contained in its caused waste water, on the one hand the discharge of nitric acid can cause greatly to pollute to environment,
The loss of N resources also form the waste of resource simultaneously.
The content of the invention
It is an object of the invention to provide a kind of method and fertilizer that fertilizer is prepared by allantoin production waste water, this method energy
