Embodiment Construction
[0018] Below in conjunction with accompanying drawing, the specific embodiment of the patent of the present invention is described.
[0019] As shown in the figure: 1 is the main body of the reaction device, 14 is the door that can be opened and closed on the front of the device, the inside of the device is layered by partitions 9, and an earthworm with a sieve plate 7 and a handle 5 is arranged on each partition 9 Processor 6, under every layer of dividing plate 9 is provided with water spray porous pipe 3, and device both sides establishes vent 4, and device right side establishes drainage pipe 11, water collector 12 and push handle 2, and device bottom establishes pulley 13.
[0020] The earthworm processor 6 is the core of the device, and the size of the device is 1200mm*200mm*170mm. The bottom sieve plate 7 of the earthworm processor 6 is composed of 60 arc-shaped sieve bars 16, and the radian of the sieve plate 16 is π / 2, and the slit width of the sieve bar 16 is 2mm. ...

The invention relates to a device for recycling organic wastes such as straws in space bases by using earthworms. Insufficient large-scale and multi-stage continuous processing capacity, too complicated technological process and other problems. The technical scheme is that the device is layered by partitions 9, and an earthworm processor 6 with a sieve plate 7 and a handle 5 is arranged above each partition 9, and a water spray porous pipe 3 is provided under each partition 9, and the device Air vents 4 are arranged on both sides, drain pipe 11, water collector 12 and push handle 2 are arranged on the right side of the device, and pulley 13 is arranged at the bottom of the device. The device has the advantages of easy handling, low environmental pollution, multi-stage and continuous biological treatment, simple process and convenient control and management. The invention can also be applied to the processing fields of space station, space permanent base, ground polar closed system and ground agricultural organic waste.
Description
technical field [0001] The invention belongs to the field of biological treatment devices for organic waste such as straws in permanent space bases, and is mainly used in the bioregenerative life support systems (Bioregenerative Life-Support Systems, BLSS) of permanent space bases (such as moon and Mars bases) inedible biomass ( Mainly rice straw, wheat straw, etc.) earthworm biotransformation treatment. Background technique [0002] In order to realize the long-term long-distance flight of human beings in space or establish permanent bases on alien planets, various living conditions necessary for astronauts must be provided, such as food, oxygen, water, etc. Bio-regenerative life support systems are recognized as the most promising technology, one of the key issues is the disposal of non-edible parts of plants (such as straw) in the system. At present, chemical treatment, incineration, microbial treatment and soil-like matrix methods are mainly used in the world, among whi...
