Water reusing device and method based on integrated vertical-flow constructed wetland

Abstract

The invention discloses a water reusing device and method based on an integrated vertical-flow constructed wetland. The water reusing device comprises a constructed wetland, wherein one side of the constructed wetland is provided with a regulation water box and a water storage box from top to bottom, and the other side of the constructed wetland is provided with a clear water box; the constructed wetland sequentially consists of a vegetation layer, a crushed rock layer, a soil layer, a mixed layer of furnace slag and limestone, a sand particle layer and a crushed rock layer from top to bottom; a water distribution tube is connected between the regulation water box and the soil layer; a flow passage hole is formed in the bottom of each crushed rock layer. The water reusing device collects rainwater and domestic wastewater by virtue of a gravity flow without needing to use a water pump and the like to provide additional powder, and thus energy is saved. According to the water reusing device disclosed by the invention, a small-sized aerator can be arranged in the regulation water box and can provide oxygen for subsequent constructed wetland unit treatment according to the needs for water quality, and thus aerobic reaction and facultative reaction are realized, and removal of nitrogen and phosphorus is promoted. Meanwhile, with the adoption of the water reusing device, influences on water treatment caused by water quality fluctuation and weather variation are overcome, and thus effluent effect is ensured.

Description

technical field [0001] The invention relates to a single-family reclaimed water reuse device for constructed wetlands, in particular to a water reuse device and method for constructed wetlands based on composite vertical flows. Background technique [0002] With my country's economic development and social progress, people's requirements for living environment are constantly improving. In recent years, the concept of ecological housing and green building has been widely spread, and it is reflected in many new residential areas in China. Its design concept is that the residential area should not only have the function of living, but also provide the residents with a pleasing and pleasant landscape environment, and also require the reuse of resources and energy, saving, recycling and recycling during the construction and use of the community. . Residential quarters usually use waterscapes to improve the environment in the landscape, and people's requirements for waterscapes d...

Problems solved by technology

[0005] In order to overcome the problems that the existing artificial wetland system occupies a large area, is not suitable for decentralized single-family houses, has poor hydraulic conditions, low utilization efficiency of wetland beds, easy to block, and low removal rate of nitrogen and phosphorus, a method based on The compound vertical flow artificial wetland water reuse device and method can not only increase the utilization efficiency of the wetland bed, but also reduce blockage, improve the treatment efficiency of reclaimed water, achieve the purpose of reducing land occupation, and are suitable for decentralized single-family houses
