Abstract

The invention discloses a wetland treatment method for domestic sewage in a terrace area, which comprises the following steps of: establishing a wetland with a gradient range of 25-35 degrees by utilizing terrace topographic advantages, planting aquatic plants in the wetland, and packing water purification fillers in the wetland. From a water inlet to a water outlet, sewage totally passes througheight wetland pools, the first three wetland pools are percolation pools, the last five wetland pools are biological pools, and the hydraulic retention time is 8-12 days. The fillers, microorganisms and aquatic plants in the wetland can absorb pollutants in the sewage, so that the effect of purifying the sewage is achieved. Meanwhile, the wetland technology is applied to the terrace, so that the local water environment can be protected, and the effect of beautifying the environment can be achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a wetland treatment method for domestic sewage in terraced fields. Background technique [0002] In recent years, wetland technology has received widespread attention in the treatment of domestic sewage, such as the emergence of concepts such as urban wetland parks and ecological wetland protection areas. Wetland is mainly composed of aquatic plants, aquatic animals, microorganisms and their environment as a unified whole, which has obvious effects on sewage treatment. Wetland is an ecological and environmentally friendly sewage treatment measure. Wetland has multiple functions including protecting biodiversity, regulating runoff, improving water quality, regulating microclimate and providing tourism resources. At present, wetland types are mainly divided into surface flow constructed wetlands and subsurface flow constructed wetlands. Wetland research mainly foc...
