Description

Technical Field

[0001] The utility model belongs to the technical field of sewage purification and treatment, and specifically relates to an assembled sewage treatment device. Background Art

[0002] The northern region has a long winter, which is not conducive to the growth of vegetation, so greenhouses are built. In order to ensure the growth of woody plants, greenhouses made of light steel and glass are built. The irrigation in such indoor greenhouses is artificial, and stone slabs are laid around the woody plants to facilitate the passage of workers or visitors. During the irrigation process, some irrigation sewage will be generated. Pesticides or other impurities will remain in such irrigation sewage.
