【摘要】 介绍了侧滤的原理。板状滤料与水平面成一定角度设置，水流从侧面流出，在过滤的同时进行沉淀和曝气。侧滤装置结构简单，效率高，占地面积小，不需经常清洗。与其他水处理方法比较可以大幅度降低投资。侧滤装置除进水泵及排泥设备外，运动部件很少，运转费和维护费用低更多还原

【Abstract】 The principle of lateral filtration is presented in this paper.A plate like filtrating package inclined with certain slop to the horizontal is installed in a tank and the wastewater undergoes processing of sedimentation and aeration simultaneously while it flows through the filtrating material and out lets laterally.For the lateral filtration the structure is simple, the effect is high and the space requirement is small, so the investment could be decreased largely.Beyond inlet and sludge discharge pumps there are few mechanic appliances and frequent washing is not required, so the operating and maintenance expenses are low.更多还原
