Abstract
Description
technical field
[0001] The invention relates to a sewage treatment device and a treatment method, in particular to a decentralized integrated domestic sewage treatment device and a treatment method. Background technique
[0002] With the rapid development of economy and the acceleration of urbanization process, my country's water environment has been seriously polluted. The current sewage treatment facilities are mainly urban sewage treatment plants. The scattered residential areas in rural areas are far away from urban areas, and the domestic sewage generated by them is difficult to connect to the urban sewage pipe network; this part of the sewage pipe network is difficult to collect or centrally treat uneconomical domestic sewage Collectively referred to as distributed domestic sewage.
[0003] Distributed domestic sewage mainly refers to feces and flushing water, bathing sewage and catering sewage produced by residents in the production or living process, and also includ...
Examples
Embodiment 1
[0030] Distributed domestic sewage integrated treatment device, such as figure 1 with figure 2As shown, it comprises a water inlet pipe 13, an aeration device 14 and a housing 1 with an open top, and the inside of the housing 1 is divided into an anaerobic reaction chamber 2 by a first porous partition 5 and a second porous partition 6. The oxygen reaction chamber 3 and the artificial wetland chamber 4, the anaerobic reaction chamber 2 is located below the first porous partition 5 in the shell 1, the anaerobic reaction chamber 2 is equipped with a perforated water pipe 7, the water inlet pipe 13 and the perforated water pipe 7 Connected, the anaerobic reaction chamber 2 is filled with anaerobic filler 9 above the perforated water distribution pipe 7; the aerobic reaction chamber 3 is located between the first porous partition 5 and the second porous partition 6 in the shell 1, and the aerobic The reaction chamber 3 is equipped with an aeration pipe 8, the air inlet end of th...
Embodiment 2
[0038] Example 2 is the same as Example 1, except that the ratio of the cross-sectional areas of the anaerobic reaction chamber 2, the aerobic reaction chamber 3 and the constructed wetland chamber 4 is 1:0.8:1.5; the anaerobic reaction chamber 2 is filled with anaerobic The particle size of the oxygen packing 9 and the anaerobic packing 9 is 1 cm, and the ratio of the thickness of the filling layer of the anaerobic packing 9 to the height of the anaerobic reaction chamber 2 is 0.5:1; the aerobic reaction chamber 3 is filled with a foam block 10, and the foam block 10 It is a polyurethane foam block with a size of 2cm×2cm×2cm. The ratio of the thickness of the filling layer of the foam block 10 to the height of the aerobic reaction chamber 3 is 0.5:1; the artificial wetland chamber 4 is filled with a planting matrix 11, which is pebbles , the aquatic plants 12 are canna, chrysanthemum, water celery and calamus, and the thickness of the planting substrate 11 in the artificial we...
Embodiment 3
[0040] Example 3 is the same as Example 1, except that the ratio of the cross-sectional areas of the anaerobic reaction chamber 2, the aerobic reaction chamber 3 and the constructed wetland chamber 4 is 1:1.2:3; the anaerobic reaction chamber 2 is filled with anaerobic The particle size of the oxygen packing 9 and the anaerobic packing 9 is 10 cm, and the ratio of the thickness of the filling layer of the anaerobic packing 9 to the height of the anaerobic reaction chamber 2 is 0.6:1; the aerobic reaction chamber 3 is filled with a foam block 10, and the foam block 10 It is a polyurethane foam block with a size of 5cm×5cm×5cm. The ratio of the thickness of the filling layer of the foam block 10 to the height of the aerobic reaction chamber 3 is 0.6:1; the artificial wetland chamber 4 is filled with a planting matrix 11 containing Iron ore slag, aquatic plants 12 are chrysanthemum, Siberian iris and calamus, and the thickness of planting substrate 11 in the artificial wetland cha...
