Abstract

The invention discloses an in-situ water body ecological restoration system for the restoration of black and odorous water bodies in rural areas, including a primary filter assembly, a secondary filter assembly, an aeration and oxygenation assembly, a plant floating bed, a primary filter assembly, and a secondary filter assembly There are fixed plates across both sides of the river. The surface of the fixed plate is continuously and equidistantly provided with a number of slots. Each set of slots is equipped with a filter plate set. The filter plate set is connected end to end by a number of filter plates. The aeration and oxygenation components include connecting rods, several air pipes, several branch pipes and an exhaust assembly located at the bottom of each group of branch pipes. The branch pipes are connected to the air pipes in rotation, and the branch pipes are equipped with retractable baffles. plate. The water ecological restoration system of the present invention is able to purify and repair rural black and odorous water well and improve the fluidity of river hydraulic circulation through a restoration system combining filter components, aeration and oxygenation components, microbial purification and plant floating beds.

Description

technical field [0001] The invention relates to the technical field of restoration of black and odorous water bodies, in particular to an in-situ water body ecological restoration system used for restoration of black and odorous water bodies in rural areas. Background technique [0002] Rural black and odorous water is a water body with a black bottom and a foul odor. It is an extreme state of water pollution. The main reasons for its occurrence are: the discharge of organic pollutants, untreated pesticides, fertilization wastewater and domestic , industrial wastewater and rainwater mixed into the river, causing river pollution. Black and odorous water bodies can easily lead to the death of animals and plants, and cannot be irrigated. When the water body is seriously polluted, the concentration of pollutants deposited in the sediment will far exceed the concentration in the overlying water body with the passage of time. [0003] The pollutants in the sediment can flow throu...
