The Ammoia Shedding Experiment of Rare Earth Waste Water and Government Engineering Design
　　This article blows shedding the law processing wet law of rare earth to smelt the high consistency ammonia nitrogen waste water experiment course,and simple states experiment technology route and process flow,and has been in progress the analysis to the experimental data,and by way of the experiment result explanation, pH,the temperature of the waste water Block neodymium magnet and blows to shed time as well as gas liquid to shed effect and has the very big influence than to blows.Wastewater ammonium chloride is treatmented through the intersecting experiment;the thesis comes to conclusion that the primary and secondary parameters order of the influencing factor about blowing is pH,air tripping temperature,air tripping time and gas-liquid ratio.
　　The conclusion are drawn with single factor that the economic practical operation conditioning is pH 12,air tripping temperature 30℃,air http://www.chinamagnets.biz/ tripping time 3 hours,the gas-liuuid ratio 6000 and under this condition,the ammoniac concentration reduce from 12017.6mg/L to 336mg/L and removal rate can reach over 97.2%.At one time,the wastewater can approximately reclaim ammoniums sulphate.According to designs the firsthand information which the project description and provides,carries on the design to the Baotou rare earth ammonium sulfate waste water.The processing water volume is 200 m3/h,the content of ammonia nitrogen is 15g/L,the totle hardness is 14000mmol/L.Block neodymium magnet Removes in the waste water the ammonia nitrogen is in this design primary mission,in the waste water ammonia nitrogen mainly through blows escapes the tower carries on the steam to blow escapes,causes the ammonia to be separated from the waste water together along with the steam,but this steam turns the ammonia water through the condensation,and the ammonia water is uses in the production craft of rare earth; After blows the waste water which escapes to pass through again the ion-exchange reactor,causes in the waste water the ammonia to reach the sign.
