The secondary pipe of the disinfection pipe is in the same management as the secondary pipe of the first recovery pipe, the secondary pipe of the second recovery pipe and the secondary pipe of the water replenishing pipe.

Because water can cause the water conservancy to the active carbon after getting into the active carbon filter and strike the back flush pipe in, the easy scattering of active carbon is strikeed, reduces the active carbon volume, in order to solve this problem, this embodiment has designed the structure of active carbon filter.

The activated carbon filter comprises a tank body, wherein the top and the bottom of the tank body are respectively provided with a water inlet and a water outlet. A flow retarder communicated with the water inlet is arranged in the tank body. The jar is internal to be equipped with the backup pad, is equipped with a plurality of filter caps in the backup pad.

When the activated carbon filter is used, water enters the hollow circular plate through the water inlet of the tank body and the connecting pipe, falls off from the sprinkling holes of the hollow circular plate and flows on the conical plate and flows down along the surface of the conical plate. The structure reduces the impact of water entering the activated carbon layer directly from the water inlet of the tank body, so that the activated carbon cannot be flushed by water to run around to enter the backwashing water outlet in a large quantity, and the problem of reduction of the filtering effect is caused. The rotating shaft and the rotating fan blades are used during backwashing, the fan blades rotate to cause stirring of the activated carbon layer during backwashing, and impurities adsorbed by the activated carbon are more easily flushed out.
