Abstract

The invention discloses a multi-stage ecological sewage purification treatment device which comprises a water collection well, a primary sedimentation basin with a grating, a hydrolysis acidification basin, an ecological filtering tank and an artificial wetland, wherein all the treatment basins are communicated with one another; a filler layer is laid at the bottom of the ecological filtering tank; a foam plate is arranged on the upper part of the ecological filtering tank, and aquatic plants with strong roots are planted on the foam plate; the filler layer is formed by mixing more than two of large gravels, cobblestones and quartz sand; microorganisms are attached to the filler layer to form a microorganism film; the roots of the aquatic plants are buried into the filler layer. The multi-stage ecological sewage purification treatment device disclosed by the invention has a good sewage treatment effect and can treat sewage without power or other energy; the problems of high probability of blockage and large sludge amount of a conventional sewage facility are solved; furthermore, flowers can be cultivated and fishes can be bred as ornamentals, and economical benefits are achieved.

Description

technical field [0001] The invention relates to the sewage and waste water treatment industry, in particular to a device and a sewage treatment method for multi-stage ecological purification and treatment of sewage. Background technique [0002] Constructed Wetland Ecological Treatment Constructed wetland is a comprehensive ecosystem. It applies the principles of species symbiosis, material recycling and regeneration, and the principle of structure and function coordination in the ecosystem. On the premise of promoting the virtuous cycle of pollutants in wastewater, the production potential of resources is fully utilized. , to prevent the re-pollution of the environment, and obtain the best benefits of sewage treatment and resource utilization. [0003] The use of constructed wetlands to treat sewage can be traced back to 1903. It was built in Earby, Yorkshire, England. It is considered to be the world's first constructed wetland for sewage treatment, and it operated continu...
