A gas water backwashing filter function with water and air distributing device comprises a water distributing pipe and a water distributing pipe group; the distribution of water pipe on the bottom of the hole, the side wall is provided with a back flushing hole, the top is provided with an exhaust hole; and one end assembly hole water distribution pipe the group is sealed and installed in the distribution of water within the trachea, including a set of water distribution pipes and the distributing pipe distribution pipe and filter in underground water distribution trough is arranged on the air pipe and the air cushion layer cloth cloth hole and filter assembly is communicated with the formation of underground water. The backwash water hole and the distribution of water and gas does not directly filter and filter in direct relative, air or water should be bent upwards, the supporting layer of filter redistribution, so there is enough time uniform distribution, so the gas water into the filter layer evenly, without washing from the dead; and will not peel the filter dirt from the pores or holes into the backwash water distribution pipe, no pollution.
【技术实现步骤摘要】
本技术涉及一种具有气水反冲洗功能滤池的配水配气装置。
技术介绍
滤池是城市给水、废水处理及工业生产中必不可少的水处理设备。而滤池是通过滤料的过滤及吸附作用对水进行过滤处理的,因此当滤料在使用一段时间后,滤料层上会累积一些污垢,这样将影响出水水质和产量,这时就要对滤池进行反冲洗,以便将沉积在滤料层上的污垢清洗掉。常见的滤料清洗方法有使水在整个滤层平面内自下而上地穿过滤层,使滤层部分或全部悬浮,在滤料颗粒的相互碰撞磨擦及水流剪切的作用下,将滤料冲洗干净,如果在此过程中同时使空气一起参与冲洗过程,即气水反冲洗,则冲洗效果更好。现有技术中,气水反冲洗装置是在滤池的滤层下方设置反冲洗进水管,在该进水管的顶部开有若干通孔,当进行反冲洗时,将气水混合物由该进水管的顶部通孔向滤层进行冲洗,或者先进空气,使滤料松动同时使污垢剥落,然后再同时进水,以气水混合物将污垢冲入滤层顶层,再将污水由排污口排出。然而此反冲洗过程却存在下列缺点1、由于具有一定压力的气水由所述的通孔直接冲向滤层,且各通孔之间具有排布间隙,因此使冲洗不均匀,直接被冲到的滤料污垢易剥落,其余部分则不易冲洗干净,存在冲 ...
