Embodiment

[0018] (1) The device is 2m long, 2m wide, and 2.5m deep. The thickness of the filter material layer is 2.4m. The interior is filled with infiltration medium with a thickness of 2.4m. The infiltration medium is alluvial river sand, which is divided into three layers: the lower layer is for infiltration The supporting layer 3 at the bottom of the medium is 0.5m thick, and the particle size of the filtration medium is 32-16-8mm from bottom to top; the middle layer is the middle layer 2 of the filtration medium, and the thickness is 1.4m. It is the uppermost layer 1 of the infiltration medium, with a thickness of 0.5m and a particle size of 1-1.2mm; the supporting layer 3 at the bottom of the infiltration medium is equipped with an outlet pipe 8 .

[0019] (2) The main water distribution pipe 10 is vertically connected to the water distribution main pipe 4, and the water distribution main pipe 4 is vertically connected to the water distribution branch pipe 5. The outlet hole 6 an...

Abstract

The invention discloses a water distribution device for strengthened land domestic sewage treatment. A water distribution main pipe and one part of branch pipes are buried at the depth of 50cm of an infiltration medium, the pore size of water outlets of the branch pipes is 2mm, and the hole pitch is 100mm; and the other part of branch pipes are positioned on the medium, the branches positioned onthe medium and positioned at the depth of 50cm of the medium are arranged in a staggered way at an interval of 1m, and the pore size of water outlets of the other part of branch pipes is 2mm. Meanwhile, the water distribution branch pipes buried at the depth of 50cm of the infiltration medium are connected with vent pipes extending out of the infiltration medium. By the device, mass transfer efficiency from the air to the infiltration medium and reoxygenation effect are improved, the denitrification effect of the system is further enhanced, power is not needed in the whole reoxygenation process, power consumption is avoided, the construction is convenient, the arrangement is simple, and a rule of low manufacturing cost and low operating cost for land treatment is followed.

Description

technical field [0001] The invention relates to a water distribution device for domestic sewage land intensive treatment, which improves the mass transfer efficiency and reoxygenation efficiency of oxygen in the air to the soil infiltration medium by improving the conventional water distribution system. It belongs to the technical field of environmental protection. Background technique [0002] With the development of the economy and the acceleration of the urbanization process, the shortage of water resources and serious water pollution have become common environmental problems. From a national perspective, water pollution from domestic sewage is spreading from cities to rural areas. In actual production and life, the treatment of rural domestic sewage is particularly difficult due to its characteristics different from urban domestic sewage. The land intensive treatment technology, such as artificial rapid infiltration process, uses artificial medium backfill, high hydraul...
