The water is then introduced into the rain pipe 306 through the three-way pipe 308, and then uniformly falls onto the filter cotton in the dry-wet separation box 309. Various impurities in the water, such as oil film, floating matter, feces, residue, bait, etc., are intercepted on the filter cotton, and the remaining clean water passes through the filter cotton. The water after dry-wet separation reaches the second lower filter bin 304, and the water is pumped back to the upper water pump bin 216 through the third water pipe 307 by the upper water pump 205 for circulation.
