Description
Technical field
The invention belongs to technical field of sewage, more particularly to a kind of resource recovery device for source-separated urine.
Background technology
Research data shows, the nitrogen containing 8000~10000mg/L and 700~2000mg/L P elements in urine.
Think that the slops such as urine are a kind of pollutants according to current theory, needs a large amount of water source to go to rinse, water is caused to provide
The huge waste in source and N, P nutriment.Since the nutriments such as nitrogen phosphorus are the important components of fertilizer, by the nutrients in urine
Matter is recycled, and on the one hand can solve the problems, such as that sewage treatment plant inflow nitrogen and phosphorus load is high, improves effluent quality；Another party
The product in face, recycling can be used as agricultural production fertilizer, realize recycling for resource.
Currently, in urine there are mainly three types of nutrient recovery technologies:(1) phosphorus is individually recycled, for example uses ammonium magnesium phosphate
Recycling of the chemical precipitation method to phosphorus from urine；(2) nitrogen is individually recycled, for example the ammonia in sewage has been recycled using ion-exchange
Nitrogen individually recycles urea in urine using isobutanediurea (IBDU)；(3) the synchronous recycling of nitrogen phosphorus, for example divide completely in urea
Solution generates stable fertilizer phosphorus to combine synchronous recycling nitrogen phosphorus with other methods using magnesium ammonium phosphate sediment method on the basis of ammonia nitrogen
Sour ammonium magnesium (guanite), recyclable about 90% nitrogen of this method and 98% phosphorus.
It is the best choosing that nutrient recycles in urine that magnesium ammonium phosphate sediment method, which synchronizes recycling nitrogen phosphorus, in three of the above method
It selects, but the application of this method must be set up on the basis of a large amount of decomposition and inversions of the urea in urine.Under natural conditions, fresh urine
Quadrafos in liquid can be quickly resolve into PO (in 1 day)4 3-；When the closed placement of freshly voided urine, it is non-that urea is converted into ammonia nitrogen
Often difficult, even if standing time is up to 20 days, conversion ratio is generally less than 25%.Therefore, how to accelerate urea in urine to be converted into
The rate of ammonia nitrogen becomes the key factor that magnesium ammonium phosphate sediment method synchronizes recycling nitrogen phosphorus.The patent of auspicious et al. the applications of Fu Jin
(CN201010168444.8) method is the pH that NaOH is added and adjusts urine, subsequent dosing, stirring precipitation；Dong Liang fly et al. application
Patent (CN201110037688.7) method be can be certain by closed standing long period, these methods after urine collecting
Promote the urea in urine to be converted into ammonia nitrogen in degree, but also has prodigious defect on hydrolysis rate and final effect, it is practical
It is ineffective in application process.The method of the hydrolysis of urea of most effective promotion is to add urine enzyme, and research data shows to contain in urine enzyme
Under conditions of amount is 50mg/l, 85% urea can be converted into ammonia nitrogen in 8 hours in urine, but since urine enzyme is very expensive, limit
The large-scale application of this method is made.
