Embodiment

[0032] Such as figure 1 As shown, the experiment process was carried out in Changtu County, Tieling City, and was used to treat polluted landscape water bodies, with a maximum treatment volume of 6m 3 / h, the main structure includes a reoxygenation tank body 3, an ecological filter tank body 14, a fan 10, and a water collection channel pool body 8.

[0033] Specific dimensions: reoxygenation tank body 2m×1m×2m, ecological filter tank body 5m×1m×2m, water collection tank body 1m×1m×2m.

[0034] The reoxygenation tank 3 is composed of a water inlet 1, a grille 2, an aeration pipe 11 and an overflow wall 4. The overflow wall 4 is composed of three overflow holes 12 with different heights, and the reoxygenation tank body is designed to be buried, which can reduce the breeding of mosquitoes and flies and the diffusion of odor.

[0035] The ecological filter 14 is composed of filler 13 , peat soil 5 , aquatic plants 6 , overflow wall 4 , and aeration device 11 . The particle size...

Abstract

The invention relates to a sewage treatment system based on an artificially intensified ecological filtering bed and application of the sewage treatment system. The sewage treatment system consists of grids, an oxygen-enriched pool, an ecological filtration bed, oxygen-enriched plants, an aeration system, a variable water level regulation system and a water collection canal, wherein the bottoms of the oxygen-enriched pool and the ecological filtration bed are respectively provided with an aeration pipe connected with a fan and ecological padding with the inner filling diameter of the ecological filtration bed of 8-16 cm; and the variable water level regulation system in the water collection pool can regulate the water conservancy load of the filtering bed. By using the sewage treatment device designed by the invention, an aerobic area and an aerobic area are formed in the same filtration bed through opening and closing of the aeration pipe, nitrifying and denitrifying processes are completed in the same filtration bed, thus the sewage treatment device has an efficient denitrification capability. According to the invention, oxygen-enrichment is carried out through a root system of a plant, and energy consumption and back wash frequency are greatly reduced while forming an efficient denitrification capability.

Description

technical field [0001] The invention relates to sewage treatment, in particular to a low-energy consumption artificially reinforced ecological filter bed sewage treatment system used in various climatic conditions and its application. Background technique [0002] In recent years, with the rapid development of my country's township enterprises and intensive breeding industry, a large amount of industrial, agricultural and domestic sewage has been directly discharged into rivers without any treatment, and the water environment of rural rivers has been seriously polluted and destroyed. The river channel is silted up, the water body is turbid and even black and smelly, and the function of the polluted river water as a source of domestic and industrial water has been completely lost. Ecological filter bed is a traditional sewage treatment device, which has the characteristics of low investment and operation cost, but its usual form is a single anaerobic or aerobic form, which can...
