Embodiment 1
[0046] A method for domestic sewage treatment and reclaimed water reuse, comprising the following steps: sending domestic sewage or aquaculture wastewater and organic residues into an annular anaerobic pond area 1 through a water delivery pipe, and passing through an organic filler layer 4 in the anaerobic pond area Filtrate is formed by filtration, adsorption, sedimentation, decomposition, and mineralization. When no rainfall event occurs, the filtrate passes through the permeable high inner wall 5 located at both ends of the anaerobic pond area to reach the ecological pond area 2, and the filtrate first passes through the ecological pond area 2. After being purified by the shallow water area 21, it is filtered by the permeable low inner wall 7 between the shallow water area 21 and the deep water area 22, and finally reaches the deep water area 22; when a rainfall event occurs, the rainwater is collected and confluent through the glass greenhouse 11 and the rain collection pipe...
Embodiment 2
[0048] An ecological device for domestic sewage treatment and reclaimed water reuse, comprising an inner wall built on an impermeable foundation, an impermeable outer wall 3 and a permeable low inner wall 7 arranged in the inner wall, the impermeable outer wall 3 in two Water inlets 13 are arranged in the center of two relative wall surfaces, and the inner wall encloses an ecological pond area 2, and the impermeable outer wall 3 and the inner wall form an annular anaerobic pond area 1, and the sand layer 9 is filled in the anaerobic pond area. At the bottom of the oxygen pond area 1 and the ecological pond area 2, an organic filler layer 4 is arranged on the sand layer top of the anaerobic pond area 1, and snails 26, small floating plants 24, emergent plants 23, bottom Habitat fish 25; the inner wall includes two opposite permeable high inner walls 5 and two impermeable walls 6, the anaerobic pond area 1 and the ecological pond area 2 exchange liquid medium through the permeabl...
Embodiment 3
[0057] This specific implementation plan takes a rural family of 5 as an example, and the device covers an area of 12.5m 2 (5×2.5m).
[0058] First dig a foundation pit of 12.5m 2 (5m long, 2.5m wide) × 2.7m (depth), build a 0.2m thick impervious foundation 10 at the bottom of the foundation pit, and then build a 3m (height) × (18cm thickness) impermeable exterior along the outer edge of the impervious foundation 10 Enclosing wall 3, so that the impervious outer wall 3 is 0.5m above the ground level. A water inlet with a height of 0.3 m and a width of 0.5 m is set in the center of the two opposite walls of the impermeable peripheral wall 3, so that the height of the upper side of the water inlet is 0.2 meters from the ground level, and one water inlet is connected to domestic sewage, and the other water inlet is connected to aquaculture. waste water.
[0059] Build the inner wall in the impermeable outer wall 3, including two relatively high permeable inner walls 5 and tw...
