A molecular probe-based safety prewarning and fault location system for an electrochemical energy storage station includes a molecular probe label, a camera, and a host. The present disclosure realizes real-time safety prewarning of a fault of an electrochemical energy storage device based on a color change of a gas sensing region of the molecular probe label, and locates an abnormal electrochemical energy storage device based on a position marker region of the molecular probe label or a position of the camera on a slide rail when the camera is facing the molecular probe label. Operation and maintenance personnel of an energy storage station can obtain a prewarning signal in time and take a corresponding safety measure. The molecular probe technology is a drive-free technology with advantages of high sensitivity, low costs, and anti-interference. It has important application value for operation safety of a large-scale energy storage station.

Disclosed is a method for preparing bittern-carbonization synergistic reinforced recycled aggregate, including the following steps: spray pretreatment: performing alternate spraying on recycled aggregate with bittern and lime milk at intervals for many times at 4-70° C. and a pressure of 0.05-0.6 MPa; carbonization reinforcement: introducing waste gas containing carbon dioxide for a retention time of 4-8 h after the recycled aggregate is allowed to stand for 2-4 h; and rinsing and air drying: removing soluble impurities on a surface of the recycled aggregate by rinsing in water, and performing air-drying on the recycled aggregate to obtain bittern-carbonization synergistic reinforced recycled aggregate. According to the present disclosure, the effective reinforcement of recycled aggregate at normal temperature and pressure in a short time is realized, and the method is simple in process and is convenient in operation.
