[0036] Specifically, Figure 2 As shown, a drain pipe 7 is provided at the bottom of the box body 1.

[0037] First, the circulating water of the cooling tower enters the interior of the box body 1 through the inlet pipe 201 arranged on the top of the box body 1.

The filter screen 203 inside the inlet bucket 202 will preliminarily remove large particles of impurities in the water. Then, the water after preliminary filtration flows into the pretreatment bucket 205 through the outlet hole 204. In the pretreatment bucket 205, the water passes through the coarse gauze 206, the fine gauze net 207 and the fiber cotton filter screen 208 in turn.

The cooling tower circulating water enters the interior of the box body 1 through the inlet pipe 201 arranged on the top of the box body 1. The water first enters the inlet bucket 202 located at the top of the box body 1. The filter screen 203 inside the inlet bucket 202 will preliminarily remove large particles of impurities in the water. Subsequently, the preliminarily filtered water flows into the pretreatment bucket 205 through the outlet hole 204. In the pretreatment bucket 205, the water passes through the coarse gauze 206, the fine gauze net 207 and the fiber cotton filter screen 208 in turn. These three layers of filter materials can gradually remove particulate impurities and organic matter of different sizes in the water. The coarse gauze 206 mainly removes larger particles, the fine gauze further removes small particles, and the fiber cotton filter screen 208 uses its good adsorption performance to remove In addition to removing suspended solids and organic matter from the water, at the same time, an air outlet component 3 is provided on one side of the pretreatment device 2. The air outlet pipe 301 of the air outlet component 3 is located on one side of the box body 1.

An activated carbon plate 4 is also provided inside the box body 1 to adsorb organic matter in the water and improve the water quality. An arc corner 5 is provided below the activated carbon plate 4 to facilitate smooth water flow and reduce the impact of the water flow.
