Abstract

The invention discloses an efficient purification system and purification method for domestic sewage. The purification device comprises a filter tank, an ecological tank, an electrolytic tank, an anaerobic tank and an interception tank which are sequentially communicated from left to right, a water inlet pipe is arranged at the bottom of the filter tank, a filter device is arranged in the filter tank, a gravel layer, a grass residue layer, a wood chip layer, a vesuvianite layer and a zeolite layer are sequentially arranged in the ecological tank from top to bottom, and duckweed is planted in the gravel layer; a soil layer I, a carbon residue layer, a soil layer II and a steel wire mesh layer are sequentially arranged in the electrolytic tank from top to bottom; a soil layer III, an interception layer and an activated carbon layer are sequentially arranged in the interception tank from top to bottom, aquatic plants are planted in the soil layer III, a drainage pipe is arranged at the bottom of the interception tank, the filter tank and the ecological tank are located at the same horizontal height, and the electrolytic tank, the anaerobic tank and the interception tank are located atthe same horizontal height and are lower than the filter tank. The purification device and method can be used for effectively removing pollutants in domestic sewage and realizing a water body purification effect.

Description

technical field [0001] The invention belongs to the technical field of domestic sewage purification, and in particular relates to a high-efficiency purification system and purification method for domestic sewage Background technique [0002] As the country pays more attention to point source pollution caused by industrial sewage discharge, agricultural sewage pollution and rural domestic sewage pollution have gradually become the main sources of eutrophication in river water. The high nitrogen and phosphorus content in the water body will cause massive growth of algae and cause the death of a large number of aquatic plants and fish. Rural domestic sewage is the sewage produced by households in villages and towns from washing, bathing, cooking in the kitchen, excrement and its washing. Rural domestic sewage has the characteristics of wide dispersion, multiple sources, rapid growth, complex sewage components, and large changes in water quality and water volume. It is difficul...
