Embodiment
Below in conjunction with embodiment, the utility model is further described, but protection domain of the present utility model is not only confined to embodiment.
Shown in composition graphs 1, Fig. 2 and Fig. 3, a kind of directed aerator, aeration case 1, described aeration case 1 is closed structure, and inside dividing plate 5 is separated into several solarization air cell 7, the equidistant setting of dividing plate 5, the spacing of dividing plate 5 is 100 ~ 200mm, preferably 100 ~ 150mm.
Continue shown in composition graphs 4, the side bottom aeration case 1 is provided with water inlet pipe 3, and for passing into waste water, water inlet pipe 3 is just provided with a water-in 31 to the place of each solarization air cell 7, waste water enters solarization air cell 7 by these water-ins 31.The diameter of water inlet pipe 3 and the diameter ratio of water-in 31 are greater than 2, and this ratio is larger, goes out water distribution more balanced, and preferably described diameter ratio is 2 ~ 10.
Continue shown in composition graphs 5, the opposite side bottom aeration case 1 is provided with inlet pipe 2, and be provided with an air intake branch 21 be communicated with described inlet pipe 2 in each solarization air cell 7, air intake branch 21 is provided with several solarization air caps 211.In like manner, inlet pipe 2 is greater than 2 with the diameter ratio of air intake branch 21, and preferably 2 ~ 10, air intake branch 21 is greater than 2 with the diameter ratio of solarization air cap 211, and preferably 2 ~ 10, be beneficial to gas uniform distribution, and waste water fully mixes.
