Embodiment Construction
[0014] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings.
[0015] The structure of the drip irrigation device that converts domestic sewage into plant nutrient solution under the high-slope terrain of the present invention is shown in Figure 1, mainly including the water inlet and collection pipe 1 of domestic sewage, the hydrolysis acidification tank 5 with biological carriers, and the light-weight Filled solid-liquid separation tank 7 and outlet pipe 10 with drip irrigation filter head at the end. The top inlet of the hydrolytic acidification tank 5 is connected to the water inlet collection pipe 1, and the biological carrier 2 that provides anaerobic bacteria attachment and growth is arranged in the hydrolytic acidification tank 5. The biological carrier 2 is connected in series by a plurality of nylon ropes 3, and multiple sets of nylon ropes 3 It is fixed with two round steels 4 up and down, and th...

A drip irrigation device for conversion of domestic sewage to plant nutrient solution in the landform of great slope is provided. The domestic sewage is carried along inlet pipe that collecting water from the top part into the hydrolytic acidification tank, wherein organic carriers connecting by a plurality of nylon cords are laid for supporting adherence of anaerobe to grow, and through a water distribution wall the outlet at the bottom of the hydrolytic acidification tank connects the solid-liquid separation tank where a plate is laid for supporting fixed lightweight filler, and filters on the top part irrigate cash crops by outlet pipe and the water outlet is on the top of solid-liquid separation. The present invention converts the domestic sewage to nutrient solution for cash crops by the biological effect of anaerobe on the organic carriers in the hydrolytic acidification tank, and intercept light floating material in the sewage efficiently to prevent block up of irrigation filter by the lightweight filler in the solid-liquid separation tank. Said invention makes effective use of domestic sewage preventing the pollution of water.
Description
technical field [0001] The invention relates to a drip irrigation device for converting domestic sewage into plant nutrient solution. Using mountainous areas, hills, sloping farmland and other high-slope landforms, the domestic sewage is converted into nutrient solution for economic crops in conjunction with water-saving drip irrigation to realize life. Recycling of sewage. The invention belongs to the technical field of environmental engineering sewage treatment. Background technique [0002] The Three Gorges Reservoir is located in the lower reaches of the upper reaches of the Yangtze River. The reservoir submerged area affected by backwater and the 19 counties and cities involved in resettlement are called the reservoir area, which is one of the main ecologically fragile areas in the upper reaches of the Yangtze River. The main soil types in the Three Gorges reservoir area are yellow soil, yellow brown soil, purple soil, yellow lime soil, brown lime soil, paddy soil, all...
