Abstract

The invention belongs to the field of sewage treatment and particularly relates to a lake sewage treatment device. The lake sewage treatment device provided by the invention has the benefits that a structure that a floating bed is arranged on an upper layer, a connecting net is arranged in the middle, and a sinking bed is arranged on a lower layer is adopted, so that the effect of upper, middle and lower layered purification of a lake water body is realized; a chemical sedimentation method, a biological remediation method and a physical adsorption method are combined, so that the sewage treatment and purification effects are significant, the performance is reliable, and the purification efficiency is high.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a lake sewage treatment device. Background technique [0002] With the rapid development of my country's industrialization and urbanization, especially the rapid growth of the national economy for many years, the output of domestic sewage and industrial wastewater is increasing day by day, and the discharged sewage has seriously affected people's water safety and caused damage to the environment. significantly polluted. At present, my country's concept of river and lake governance has gradually changed from engineering governance to biological restoration and ecological restoration. Conventional key technologies mainly include integrated water treatment facilities, biological contact oxidation, artificial wetlands, ecological floating beds, river [0003] Aeration etc. However, most of the existing lake sewage treatment devices are planar designs of floating beds, the...
