| 摘 要： | 根据石英砂粒径与颗粒密度的关系，研究砂滤罐处理工厂化养鱼循环水效果，该试验采用了2组并联的3层滤料普通砂滤罐，根据几何、物理原理，以石英砂最大颗粒密度，粒径3 mm作为中层，粒径2 mm和5 mm作为上下层，且颗粒密度均小于中层的设计。进行砂滤罐工厂化循环水处理效果和反冲洗再生效果的试验，结果表明：悬浮物去除效果极为显著（P＜0.01），去除率达99.83%，达到了去除悬浮物的要求。砂滤罐经过反冲洗后，能够再生使用。 |

| Abstract: | Two groups of three parallel ordinary sand filter tanks were used in the experiment. According to the physicaland geometric principles, quartz sand with particle size of 3 mm was selected as the middle-level, while 2 mm and 5 mmas the upper and lower level, respectively. The particle densities of the upper and lower levels were less than that of themiddle one. An experiment of water treatment on factory recycled water by sand filter and its backflushing renewableeffect was carried out. The results showed that suspended solids removal efficiency was extremely significant (P<0.01),which removal rate reached 99.83%, and sand filter tank after backflushed was renewable to be used. |
| Keywords: | water treatment particle size fish ponds quartz sand industrial aquaculture sand filter tank culturing recycled-water |
