Problems solved by technology

[0002] In the toilets used in forest farms in cold areas, sewage is usually discharged in the forest farms to treat and reuse the sewage, but all the sewage is fertilized in the forest farms, so that in winter, if the sewage is directly discharged on the soil surface of the forest farms, it is easy to freeze in cold environments , leading to soil compaction
[0003] In order to achieve the above object, those skilled in the art use filter equipment to treat the sewage discharged from the toilet. However, due to the low temperature all year round in forest farms in cold regions, it is easy to freeze when using filter equipment. The water used has very high requirements on the filter equipment. When the sewage passes through the filter layer in the filter equipment, it is easy to block, which greatly affects the treatment efficiency of the sewage, and limits the application of the filter equipment in cold areas to a large extent, thus reducing the Recycling and reuse of toilet sewage

Embodiment 1

[0040] On the basis of embodiment 1, the present embodiment also includes a rough sewage treatment mechanism 1, and the rough sewage treatment mechanism 1 includes:

[0041] The settling funnel 12 of the filter screen 11 that is inclined to set and the settling funnel below the filter screen,

[0042] A sewage outlet is provided between the filter screen 11 and the settling funnel 12 , and the sewage outlet communicates with each first pipe body through the insulation pipe 13 . The lower end of the filter screen 11 is connected to a sludge collection tank 110 ; the higher end of the filter screen 11 is provided with a sewage discharge pipe 10 . Each second pipe body communicates with the third pipe body 211 , the inlet of the third pipe body 211 communicates with the outside world, and a gas heating device is installed at the inlet of the third pipe body 211 .

[0043] For this reason, the sewage generated in the bathroom is subjected to coarse filtration through the sewage r...

Embodiment 3

[0045] On the basis of Embodiment 2, this embodiment further includes a water purification device 3 for purifying the water in the sump 23 to domestic water. Each filter unit 210 can be detachably arranged in the base soil layer 21 .

[0046] For this reason, through the water purification device, the domestic water obtained by further processing the water in the sump can provide more usable domestic water for forest farms in cold regions and avoid the waste of domestic water.

[0047]To sum up, the present invention provides a toilet sewage recycling device suitable for forest farms in cold regions. The device uses a plurality of filter units arranged below the permafrost layer to carry out evolutionary treatment of the sewage, avoiding the freezing of sewage in cold regions, and Through the permeable layer between the filter unit and the base soil, a certain amount of sewage can be provided for the base soil, which is used for the fertilizer required by the planting layer ve...

Abstract

The invention discloses a toilet sewage recycling device suitable for a forest farm in a cold region, and relates to the technical field of sewage purification. The device comprises: a plurality of filtering units arranged in a foundation soil layer below a frozen soil layer in an array mode, wherein each filtering unit comprises a barrel, a water permeable layer, a broken stone layer, a filler layer and a wood chip layer, a plurality of filtering through holes are formed in the side wall of the barrel in the circumferential direction, the top of the barrel is communicated with a first pipe body for introducing sewage, a water outlet pipe and a second pipe body for introducing gas in the barrel are arranged at the bottom of the barrel, the side wall of the barrel is coated with the water permeable layer, and the broken stone layer, the filler layer and the wood chip layer are sequentially arranged in the barrel from bottom to top; and an activated carbon filter layer and a water collecting tank. According to the invention, a plurality of filtering units arranged below a frozen soil layer are used for purifying sewage, so that the sewage in a cold region is prevented from being frozen.
