具体实施方式 Detailed ways
本实用新型的一个优选实施例结合附图详述如下：A preferred embodiment of the present utility model is described in detail as follows in conjunction with accompanying drawing:
参见图1，本管道直饮水处理系统，包括一个水箱1、水箱1后依次连接一个水泵2、一个阀3、一个流量计4、一个多孔弹性滤料时滤装置5、一个阀6、一个流量计7、一个活性炭过滤器8、一个阀9和一个紫外杀菌器10。多孔弹性滤料过滤装置5和活性炭过滤器8的进水口均在上部，出水口均在下部，上部均有溢水口。Referring to Fig. 1, the pipeline direct drinking water treatment system includes a water tank 1, which is connected to a water pump 2, a valve 3, a flow meter 4, a porous elastic filter material time filter device 5, a valve 6, and a flow rate Meter 7, an activated

The compressible porous elastic filter material filter device can flexibly change the shrinkage rate according to the water quality of the treated raw water. The structure of its compressibility is: a porous plate that can move up and down is arranged on the upper part of the porous elastic filter device 5 and pressed on the porous plate. Elastic filter material. When filtering, choose a compression rate of 50% to 70%, which can achieve a stable processing effect.
图2、图3、图4和图5分别表示本实施例对浊度、铁、氨氮和亚硝酸盐的去除效果，从图中可以得出，压缩率为70％多孔弹性滤料对这些污染物有很高的去除效果，活性炭出水和多孔弹性滤料出水水质接近，因此，多孔弹性滤料的过滤大大降低了活性炭的污染负荷，延长了整个系统的运行周期。Fig. 2, Fig. 3, Fig. 4 and Fig. 5 represent the removal effect of present embodiment to turbidity, iron, ammonia nitrogen and nitrite respectively, can draw from the figure, compression ratio 70% porous elastic filter material is to these pollutions It has a high removal effect, and the water quality of the activated carbon effluent is similar to that of the porous elastic filter material. Therefore, the filtration of the porous elastic filter material greatly reduces the pollution load of the activated carbon and prolongs the operating cycle of the entire system.
图6表示的是本实施例对TOC的去除效果，从图中得出，压缩率为70％的多孔弹性过滤材料对TOC有一定的去除，活性炭利用自身的吸附和生物降解，使得TOC浓度大幅度下降。在长达数月的运行中，本工艺处理效果稳定，完全达到国家标准。What Fig. 6 shows is the removal effect of the present embodiment to TOC, draws from the figure, the poroelastic filter material of compressibility 70% has certain removal to TOC, and active carbon utilizes self adsorption and biodegradation, makes TOC concentration big decline in magnitude.

图7表示的是压缩率为70％的多孔弹性过滤材料和传统的砂滤和炭滤分别对水处理过程中，水头损失变化的曲线图。从图中可以得出，砂滤、炭滤由于滤料空隙较小，容易发生堵塞，从而水头损失较大，运行周期短，不得不进行反冲洗；而压缩率为70％多孔弹性过滤材料具有较大的空隙以及纳污量，不容易发生堵塞，运行周期长，减少了反冲洗次数，从而降低了运行成本，具有广阔的应用前景。Fig. 7 shows the curves of water head loss changes in the water treatment process of the porous elastic filter material with a compressibility of 70% and the traditional sand filter and carbon filter respectively. It can be concluded from the figure that the sand filter and carbon filter are prone to clogging due to the small gaps in the filter material, resulting in a large head loss and a short operating cycle, so they have to be backwashed; while the compressibility of the porous elastic filter material is 70%. Larger voids and dirt-holding capacity are not prone to clogging, and the operating cycle is long, reducing the number of backwashing, thereby reducing operating costs, and has broad application prospects.
