Abstract
This simple bubble Column in order to be assembled by oneself of research, join proper Pyroligneous acid, eliminate the ammonia in the simulation pig house. The ammonia in the simulation pig house is mixed and make of the ammonia water , and then via aspirated motor to be angry to simple bubble column bottom, will blowing amount control in 15 L/min. Via the testing in succession of 13 days, which show the ammonia average is 7.1±0.25 ppm. Use 15.24 cm (6〃) and 20.32 cm (8〃) PVC pipes , filled with the water amount differently as the experiment with five kinds , such as 10.9 L , 12.76 L , 14.58 L , 16.4 L , 18.2 L . Pour into the water of 60 ㎝ ,70 ㎝, 80 ㎝,90 ㎝,100 ㎝ columns separately in six inch pipes, and pour into the water of 33.7 ㎝,39.4 ㎝ ,45 ㎝,50.6 ㎝,56.2 ㎝ columns separately in eight inch pipes. Test and show, no matter all eliminated result with the capacity of 16.4 L water is the best in six inch or eight inch pipes, eliminate rate can be up to 32 hours in 100% effective time. And then add the 0.05%, 0.1%, 0.2%, 0.5%, 0.8%, 1%, 2% of pyroligneous acid , separately the experiment with the capacity of 16.4L water, can lengthen the effective time to eliminate efficiency to probe into. The result show , it is the higher in thickness to add the pyroligneous acid , it is the better to eliminate efficiency can be up to 240 hours in 100% effective. It influences test in eliminate efficiency and water temperature change in summer and Winter season for simulation ,it is by 35℃ and 20℃ of making, and examined the pH value changes, learns, the temperature of better eliminated efficiency is lower temperature. If it have treatment water which add pyroligneous acid or not , up to 100% the pH value while eliminating of change is 4.7 to 8.62 and 8.0 to 8.97. Shut the above result , design a set of automatic simple bubble column systems to get rid of odors , and with the efficiency of pH value control system of the experiment.
