The utility model discloses a modular activated sand filter, which comprises an outer tank body and an inner tank body. A movable sand bed is arranged at the lower part of the inner tank body, a circular casing is arranged at the center of the movable sand bed, an intake pipe is inserted at the upper part of the left side wall of the inner tank body, a water distributor is connected at the bottom of the annular casing, a sand guide bucket is connected below the water distributor, and an inner cavity of the annular casing is inserted and lifted. The bottom of the pipe is connected with an air lift pump, the top of the pipe is provided with a splash cap, and the bottom of the sewage tank is connected with the left and right sides of the pool body in the sand washer, and a hoisting ring is connected. The structure design of the utility model is reasonable. Through the mosaic structure of the outer pool body and the inner pool body, the utility model can not only act as a module reactor alone, but also be used in combination with the integrated sewage treatment equipment. The structure is simple, the operation is convenient, the flexibility is high, and the utility model is easy to be rebuilt and expanded. The inner pool body can be lifted out as a whole when problems arise in the operation of the device through the hoisting ring, and the loading and unloading is simple Later maintenance and management.

技术介绍
污水处理可分为一级,二级,三级处理。一级处理主要去除污水中呈悬浮状态的固体污染物质,物理处理法大部分只能完成一级处理的要求,经过一级处理的污水,BOD一般可去除30%左右,达不到排放标准。一级处理属于二级处理的预处理。二级处理主要去除污水中呈胶体和溶解状态的有机污染物质,去除率可达90%以上,使有机污染物达到排放标准。三级处理进一步处理难降解的有机物、氮和磷等能够导致水体富营养化的可溶性无机物等。随着水体污染日益严重和国家对污水排放标准不断提高,常规的污水处理多为二级处理,不能满足“提标改造”的要求,污水深度处理工艺被广泛研究和应用。活性砂滤是一种集絮凝、沉淀、过滤于一体的三级污水处理工艺,广泛应用于饮用水、工业用水、污水深度处理及中水回用处理领域。活性砂滤池利用升流式流动床过滤原理,采用单一均质滤料,过滤与洗砂同时进行,能够长时间连续自动运行,无需停机反冲洗。巧妙的提砂和洗砂结构代替了传统大功率反冲洗系统,运行能耗极低,能有效地去除污水中的悬浮物和总磷,保证最终的 ...
