Description
Technical field
The present invention relates to sewage disposal ion exchange technique field, more particularly to a kind of side of Nitrogen-and Phosphorus-containing sewage treatment and recovery
The treatment technology of method.
Background technology
Nitrogen-and Phosphorus-containing sewage is widely present in sewage treatment field, sanitary sewage, rain dirt mixed flow sewage and receives its discharge
Often contain excess of ammonia nitrogen and phosphorus in surface water.The bioremediation of common a large amount of sanitary sewages is using microorganism to ammonia nitrogen
Carrying out nitrification and denitrification makes the nitrogen in water body enter in air.Phosphorus in water body is then enriched with by microorganism dephosphorization by microorganism
It is discharged afterwards with bed mud.Links need the stringent aerobic anaerobic condition of control and the residence time is long, and as external environment becomes
The activity for changing microorganism is affected, and usually having water outlet, ammonia nitrogen is exceeded happens, and there are still trace amounts of phosphorus in being discharged
Discharge.Phosphorus is the key factor that algae is caused to overgrow and consumes dissolved oxygen in water body, and the phosphorus down to 0.03ppm can make algae
Raised growth.And bioremediation can not effectively recycle nitrogen phosphorus.Ion exchange exists as a kind of selection adsorption technology
Sewage and water treatment field have a wide range of applications, and the natural ion exchange material such as zeolite has ammonia nitrogen very strong selection to inhale
Attached effect, even absorption ammonia nitrogen can also be selected under the interference of the chlorion and sulfate radical of high concentration so as in processing water
Ammonia nitrogen is enriched with simultaneously.But common anion exchange material has it to phosphorus and without Selective adsorption in sewage
When his high concentration ion, common anion exchanger resin can substantially reduce the adsorption capacity of phosphorus.Simultaneously in ion exchange
Material, which reaches, to be generally required a large amount of drug after saturation it is regenerated.Ion exchange technique itself is easy to operate and energy consumption
It is low, but the disposition of the high concentration regenerated liquid after use and the consumption of chemicals become the prime cost system of ion exchange technique
About.
Invention content
The technical problems to be solved by the invention are to provide a kind of method of Nitrogen-and Phosphorus-containing sewage treatment and recovery, existing to solve

Desorption, then zeolite is flowed through from bottom to top, make ammonia nitrogen desorption, maximum reduces the exudation of nitrogen phosphorus, while reaching to two kinds of materials
Regeneration, and the ammonia nitrogen of absorption and phosphorus are enriched in regenerated liquid, the nutrient discovery for making low concentration in sewage is highly concentrated in regenerated liquid
The nitrogen phosphorus of degree；
5th step, regenerated liquid recycling and nitrogenous-phosphatic manure processing, magnesium chloride is added in agitator, makes magnesium ion and regenerated liquid
In ammonia nitrogen and phosphate concentration formed molar concentration 1：1：1, magnesium ion can in ammonium root and phosphate radical be co-precipitated to be formed it is high-purity
The ammonium magnesium phosphate of degree, by being detached to supernatant and precipitation, you can obtain can recycling sustainable use salting liquid and
Can be as the magnesium ammonium phosphate sediment of nitrogen phosphorus fertilizer, after filtration, sediment is recyclable to be used as good nitrogenous-phosphatic manure, and after filtering
High concentration salt solutions can be recycled as new regenerated liquid.
Preferably, the anion-exchange material is that the novel nano zirconium compound ion for having Selective adsorption to phosphorus exchanges tree
Fat HAIX-NanoZr, nanometer zirconium particle have phosphorus a Selective adsorption, and the moon such as still adsorbable nitrate anion of the functional group of resin in itself
Ion.
Preferably, the ion exchange material after being regenerated in the 4th step carries out to continue to repeat after simply rinsing again
It uses.
It is using the advantageous effect of above technical scheme：The present invention is a kind of method of Nitrogen-and Phosphorus-containing sewage treatment and recovery, 1.
