摘　　要：研究开发了一种复合变速滤池,实现了对普通滤池过滤作用的强化。试验结果表明该滤池可有效地去除原水中的浊度和亚硝酸盐氮,其去除率分别为58.82%～86.96%和33.33%～39.51%,保证了出水水质。该滤池采用变速流形式,可充分发挥深层滤料的作用。A king of combined speed-changed filter was develo pe d to enhance filtration in conventional filter.The experimental results showed t hat the filter can effectively remove turbidity and nitrite nitrogen with remova l rate of 58.82%~86.96% for the former and 33.33%~39.51% for the latter, and the effluent quality can be ensured.The filter operates with speed-changed flow,so the function of the deep-seated medium can be developed sufficiently.
