Taking the purification of water used in constructed wetlands as an example, the usage method of the present utility model will be elaborated in detail. The water used in the constructed wetland is first pumped into the crushing tank by a water pump. Then, the crushing blades rotatably arranged in the crushing tank can perform crushing operations on impurities such as waterweeds in the water. Then, the liquid pump pumps the crushed water to be treated through the drain pipe to the directly above one of the filter boxes 202. Here, it should be noted that the drain pipe can be rotated and switched through a rotary joint to be respectively located directly above the two filter boxes 202. At this time, the filter screen at the bottom of the filter box 202 can filter the small particle impurities in the water after crushing. Then, the filtered water enters the filter cavity 102 and at the same time flows into the purification cavity 103. Then, the liquid medicine in the medicine tank 300 is introduced into the purification cavity 103, and the adsorption and purification operation of heavy metal ions in the water can be realized. When the filter holes 203 at the bottom of the filter box 202 are blocked, the operator rotates the drain pipe so that the drain port is located directly above the other filter box 202, and then holds the filter box 202 with both hands and takes it out of the purification box 100 for cleaning. The present utility model can realize efficient filtration of the water to be treated in the constructed wetland through the filter mechanism 200 detachably arranged on the filter box 202 in the filter cavity 102, and it is convenient to disassemble and replace the blocked filter screen, solving the problem that the filter screen in the traditional filter box 202 is usually fixedly arranged, which leads to the situation that the filter screen is often blocked as the usage time of the filter screen prolongs. At this time, it is necessary to pump out the liquid in the filter box 202, then disassemble the blocked filter screen, replace and clean it, which is time-consuming and laborious and the operation is troublesome. The operation is simpler and more convenient, greatly improving the purification efficiency.

[0032] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense.
