In equipment of the present invention, at water capacity is that 0.4 cubic metre, supply air capacity are that 10 liters/minute, ER for emission rate are that 3 cubic metres/hour and power are under 0.6 kilowatt the condition, the moment blend level of dissolved oxygen almost reach capacity (at 20 ℃, 8.84ppm Max).The oxygen uptake efficient of this equipment is 23.9%.[comparative example 1]
Adopt the system of a spray thrower and water turbine to be used in for example breed.At water capacity is that 0.4 cubic metre, ER for emission rate are that 3 cubic metres/hour and power are that the oxygen uptake efficient of this system is 0.15% under 0.1 kilowatt the condition.[comparative example 2]
At water capacity is that 0.4 cubic metre, supply air capacity are that 10 liters/minute, power are that adopting its oxygen uptake efficient of system of a tubular type air diffuser is 0.17% under 0.6 kilowatt the condition.According to this system, if the degree of depth of flowing water is about 1 meter, then described efficient will be very low.Described tubular type air diffuser is arranged in 100 meters long rivers, and air is fed to each tubular type air diffuser to carry out dissolved oxygen increase test.As a result, through before the described test macro and the dissolved oxygen of water afterwards all be 0.5ppm, it shows any variation does not take place.[comparative example 3]
Though adopting its oxygen uptake efficient of system of an injector is best in several traditional blow and vent system, but, at water capacity is that 0.4 cubic metre, supply air capacity are that 10 liters/minute, ER for emission rate are that 3 cubic metres/hour and power are that described efficient is 3% under 0.6 kilowatt the condition.In addition, in test process, described reaction meeting stopped before end reaction.This may be because when dissolved oxygen does not exist, with making air mix Na with water rapidly

3One early the stage promptly begin the cause of oxidizing reaction, still, this reaction may be along with Na
2SO
3The reduction of concentration and make oxygen reduce.
Just as noted above, the performance that present device can present (oxygen uptake efficient) be legacy system (adopt a spray thrower and water turbine system, adopt the system of tubular type air diffuser or adopt the system of injector) 8 to 100 times of performance.
As shown in Figure 3, utilize with biological method its dissolved oxygen is reduced to 0 clear water, can be determined dissolved oxygen being increased the required power of 1ppm.As a result, the power that 0.59 kilowatt gas blower needs is 0.9KW/ppm, and present device only needs the power of 0.3KW/ppm, and it approximately is 60% of a described gas blower required drive.
Fig. 4 is a comparison diagram, and the dissolved oxygen that it shows in present device and tubular type air diffuser increases situation, and X-coordinate is represented the time, and ordinate zou is represented dissolved oxygen concentration.In this test, the changing conditions of the dissolved oxygen concentration after can also quitting work after the oxygen supply in the given time to described equipment is determined.Show some test conditionss in the lower right corner of figure.
As can be seen from Figure 4, according to equipment of the present invention, dissolved oxygen can arrive saturation value rapidly in the short period of time (15 minutes), and even can still be stabilized in this saturation value after described equipment quits work.On the contrary, in the system that adopts the tubular type air diffuser, the increase of dissolved oxygen concentration is slower, and can not arrive described saturation value.In addition, after quitting work, dissolved oxygen concentration falls to 4ppm, and keeps this value, and it is a concentration when quitting work, and promptly 1/2 of 8ppm.Above-mentioned test-results is because the diameter of the bubble that obtained in present device is 5 microns and less than the diameter of the bubble that is obtained in the legacy system, but also because bubble has homogeneity.
