The straw biological carrier is a microalgae biological film. carrier which is low in price, durable and easy to apply in a large scale, and a biological adsorbent is environment-friendly, rough in surface, high in yield, reproducible, wide in distribution and free of biotoxicity. While supporting microalgae cells to adhere and form a film, the composite film can be further used for removing various pollutants in wastewater, and can also be used as a raw material for producing organic fertilizers, high-activity biochar, energy sources and chemicals. When the fiber carrier is partially degraded into semi-rotten straw by fungi, the semi-rotten straw can be used as an organic compound fertilizer for ecological breeding or anaerobic fermentation for biogas production.

Grinding device with cold and heat exchange structure for watch part machining
InactiveCN113997135AEasy to grindImprove grinding efficiencyEdge grinding machinesRevolution surface grinding machinesAir pumpEngineering
The invention discloses a grinding device with a cold and heat exchange structure for watch part machining, and relates to the technical field of watch part grinding. The grinding device comprises a base and a first sliding rail, the upper surface of the base is connected with a first supporting seat. According to the grinding device with the cold and heat exchange structure for watch part machining, the bearing shell can be matched with the clamping acting force of a clamp to be disassembled and assembled with the first supporting seat, the bearing shell in the disassembled state can be matched with a carrying rod to conduct feeding treatment on a watchcase, and gas can be introduced into a gas groove through an arranged gas pump, an ejection block in the gas groove is ejected out of the outer wall of the bearing shell, extends into an assembling groove in the inner wall of the watchcase and is fixed, and multiple watchcases can be effectively fixed in the process, so that the multiple watchcases can be conveniently polished at the same time in the follow-up process; the inner rings of the watchcases can be polished in cooperation with a second polishing wheel, so the grinding efficiency and the grinding range of the watchcases are greatly improved, and the structure is more compact.
