Part of the electric energy generated by the wind-solar hybrid power generation device 2 supplies power and heat to the bioremediation device 5, and part of the electric energy is stored in the storage battery 27 for a temporary power supply when the natural power generation is insufficient. The equipment set 4 and the bioremediation device 5 continuously convey hot air to underwater or underground soil layers through the vertical well device 51 by using electric energy and heat energy sent by the wind-solar hybrid power generation device 2, and pump out cold air from the horizontal well device 52, thereby promoting the natural attenuation effect of microorganisms on underground pollutants and achieving the goal of remediation and treatment.
According to the vehicle-mounted bioremediation system based on the wind-solar hybrid power supply device, other devices except the bioremediation device 5 are arranged on the flat car, and installation and debugging are completed before production, so that the problems that civil engineering, installation and debugging are needed on a project site, and the period of disassembly and assembly is long are solved; the whole vehicle equipment can control the height within 4 meters, the width within 3 meters and the length within 17.5 meters according to requirements, meets the grade standard of first-grade large-scale articles of road large-scale article transportation management methods, and is convenient to transport; the project site plug and play is completely realized by the design, and the repair project with small earth volume and low total price can save large cost. This equipment fully considers integral type modularization overall arrangement, and structural design is compact, and the transportation convenience is considered to the equipment size, and installation time shortens greatly.
The invention fully utilizes abundant wind energy and solar energy resources as electric energy and heat energy required by the implementation of the bioremediation device 5, and the bioremediation device is driven to operate by green energy, thereby saving energy consumption and operating cost; the invention adopts the environmental bioremediation technology, takes the original microorganisms in water and soil as a remediation power source, and has affinity to the original water and soil.
In conclusion, the equipment installation period is short and is generally within 1 week (the well drilling time is all, and the equipment installation time is only 1-3 hours); external power supply and heat supply are not needed, and energy consumption of equipment is avoided; after the repair is finished, the properties and environment of the local soil layer are not changed, and ecological influence is not caused.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
