Abstract: The present disclosure provides a Paenibacillus mucilaginosus LT1906 and use thereof, and a microorganism-activated circulating fluidized bed (CFB) fly ash-based cementitious material and a preparation method and use thereof, belonging to the technical field of cementitious materials. The Paenibacillus mucilaginosus LT1906 has a deposit number of CGMCC No. 21337. The strain is capable of dissolving silicate minerals and aluminosilicate minerals in the CFB fly ash to increase dissolution of active SiO2. The strain is used for activating the CFB fly ash-based cementitious material, to ameliorate a large water demand and a low early strength of the cementitious material, thereby improving comprehensive utilization of the CFB fly ash in the field of building materials.

Abstract: An embodiment of the present invention provides a smart feed line automation system based on 10 kV carrier communication. The system monitors smart switches of the line via 10 kV carrier communication, detects smart transformers, and calls up and returns centralized meter-reading information of smart transformer region. Furthermore, the detection of the state of a 10 kV power line may realize real-time monitoring of the temperature, insulating level and change of voltage and current of a 10 kV aerial line and cable line, and realize alarm for an abnormal state and fault information report, so as to rapidly identify, position, isolate and recover the fault.
