Description

A kind of urine wastewater treatment method based on charcoal
Technical field
The present invention relates to the disposals of resources of the urine waste water containing emerging pollutant, and in particular to one kind is based on charcoal Urine wastewater treatment method.
Background technique
Contemporary society, as economic is constantly progressive, population it is continuous it is explosive increase, for grain needs also therewith It is increasing, and bigger grain demand, promote in agricultural production to obtain bigger grain yield and being continuously increased The usage amount of fertilizer, especially nitrogenous fertilizer, phosphate fertilizer, applied amount are even more to be continuously increased.Phosphate fertilizer mostlys come from the exploitation of rock phosphate in powder, and In use, most phosphorus can be by rainwash and soil erosion and element circular effect, finally with the shape of deposit Formula deposits in ocean, to be difficult to realize the ringing of P elements in the world, phosphorus is made to become a kind of non-renewable Resource.Today's society, with the continuous development of industrial civilization, at this stage, phosphorus demand will be estimated further to be increased, and global phosphorus produces Amount peak value will be estimated to be occurred in or so the year two thousand thirty, and phosphorus is not only Guarantee Grain Production must with meet growing world population Indispensable resource；The yield of bio-fuel production simultaneously is continuously increased, and brings additional burden to the phosphorus deposit in the whole world.
Meanwhile in the fertilizer of application, greatly do not fixed, utilize by crop, but hide in the soil, with Rainwash and soil erosion.Nutriment in fertilizer migrates therewith, enters eventually into the water bodys such as lake, river, water ring The nutriments such as excessive nitrogen phosphorus have been gathered in border, can make algae and phytoplankton large-scale outbreak proliferation in water, consumption Dissolved oxygen in water keeps aquatic animal dead due to anoxic.After algae is dead simultaneously, corpse is decomposed, and can generate a large amount of nutrition Substance, vicious circle.
Due to being rich in various nutrients in urine, it is made to cause more and more concerns in resource recovery field.Though The total volume of right urine only accounts for 4% or so of municipal sewage total amount, but it provide in municipal sewage close to 80% nitrogen and Phosphorus more than 50%, will due to that can be drained into that in natural water body or even part stain disease is unprocessed after municipal sewage treatment Direct emission, therefore higher concentration of nitrogen and phosphorus can generate strong influence to water body in stain disease, it is most direct to influence to be exactly water The eutrophication of body, causes water body to deteriorate, and aquatic animal is dead, polluted water region.Therefore the urine in municipal sewage is carried out single Reason of staying alone plays an important role resource reclaim and the load for mitigating natural water body to realize that realization recycles.
Charcoal is a kind of porous carbon-rich material, mainly by discarded biomass under conditions of anoxic, through height Warm solution generates, and is a kind of cheap sorptive material.The charcoal generally generated has biggish specific surface area and table mostly Face energy, has stronger suction-operated, and charcoal can be by pollutant in absorption environment to reduce its biological effectiveness. Mahtabet etc. thinks that charcoal can remove inorganic and polarity organic pollutant by oxygen-containing functional group, classical gravitation etc.. The comprehensive many such as Verhejen is the study found that charcoal is 10 to the 1000 of organic matter to the affinity of hydrophobic organic pollutant Times, biological carbon can remove the trace hydrophobic organic pollutant of 80-90% in soils and sediments.In addition, charcoal by pair The absorption-desorption of pollutant influences the migration of pollutant.It is (big to tylosin in soil that Jeong etc. has studied the wooden base charcoal Cyclic lactone class) absorption-desorption process influence, it was confirmed that charcoal use have to the absorption of tylosin in soil it is apparent Facilitation, and by comparison addition (5%w/w) and do not add charcoal easy miscible displacement soil column leaching the result shows that, In the soil using after charcoal, the peak value that antibiotic drenches concentration out from earth pillar reduces, the time delay that peak value occurs, simultaneously The shape of breakthrough curve is illustrated that charcoal has the desorption process of antibiotic and is prolonged from symmetrically becoming asymmetric and long streaking occur Stagnant effect.
By the urine waste water after charcoal adsorption treatment, emerging pollutant concentration meeting sharp fall therein, In this case, urine can be used as a kind of liquid fertilizer rich in nitrogen phosphor resource and be recycled, and such as be used as agricultural Fertilising process is exerted into soil, or urine waste water is further processed, and recycles nitrogen phosphor resource therein, meanwhile, it is dirty The decline for contaminating object concentration, ensure that the quality of recovery product to a certain extent.
