Green recycling treatment device for water purification and use method

The invention belongs to the technical field of water body purification, particularly relates to a green recycling treatment device for water body purification and a use method, and aims to solve the problems that in the prior art, fish excrement and food residues in aquaculture tail water cannot be recycled, a fishpond water body is difficult to purify and replace in the later period, and the cost is high. In order to solve the problem that aquatic products cannot be caught thoroughly quickly in the prior art, the invention provides the following scheme that the aquaculture device comprises a first aquaculture box body, a second aquaculture box body and a purification box body, and the top of the second aquaculture box body is fixedly connected with the bottom of the first aquaculture box body through a plurality of supporting plates. According to the loach breeding device, excrement and food residues contained in the water body can be recycled for later loach breeding, excrement, food residues and sludge ac
