The invention discloses a method for producing super active carbon. The method comprises the following steps of: mixing a carbon raw material and KOH and continuously introducing an inert gas into a reaction system; raising the temperature of the reaction system to 400 to 500 DEG C, adjusting reaction pressure to be 2 to 8 atmospheric pressures and continuously heating to activation temperature; cooling the reaction system to below 150 DEG C after the activation is finished, stopping introduction of the inert gas and continuously introducing air; and after the reaction system is cooled to below 100 DEG C, taking the activated material out and dissolving KOH and K2O in the activated material with water to realize recovery of KOH. The invention also discloses a device used by the productionmethod. By using the method and the device, the problem of serious production safety caused by production and releasing of monomer potassium in the process of producing the super active carbon by KOHactivation can be solved, so that industrial production of the super active carbon by applying the KOH activation method comes true.

The invention relates to a discharge device for totally-closed artificial environment cage culture chicken manure of specific pathogen free (SPF) chickens and a disinfection method, and belongs to the technical fields of chicken manure discharge equipment and chicken manure disinfection of coops. The discharge device comprises a coop, a chicken manure conveying belt, a tap water pipe, a chicken manure ditch, a water seal drain outlet, a residual water syphon, a discharge pipe and an outdoor water seal disinfection pond, wherein an outdoor chicken manure processing pond comprises the water seal disinfection pond; tap water is connected above the front end of the chicken manure conveying belt; the water seal drain outlet is formed in the middle of left and right central lines of the chickenmanure ditch; and the residual water syphon is arranged below the water seal drain outlet. The disinfection method for the chicken manure comprises the following step of: disinfecting in turn by selecting three disinfectants of baidusha, peroxyacetic acid and povidone iodine, wherein in the three disinfectants, a ratio of the baidusha to water is 1:(550-650), a ratio of the peroxyacetic acid to the water is 1: (325-425), and a ratio of the povidone iodine to the water is 1:(250-350). The discharge device has the advantages of reducing the labor strength of personnel, improving production efficiency and reducing potential safety hazards caused by residual chicken manure which passes in and out of a sewage channel, and has killing effect on virus.

The invention discloses a complex network-based key safety risk analysis method for super high-rise construction machinery, and relates to the technical field of application of complex network theory in building construction. The key safety risk analysis method of super high-rise construction machinery based on complex network, its characteristics include the following steps: A. Identify different types of construction machinery accident risk factors according to the super high-rise construction accident case database; B. Sorting out the relationship between risk events and factors through the fault tree Establish the adjacency matrix for causality; C. Use the software UCINET and use the adjacency matrix as an input parameter to construct a directed and unweighted complex network system model, and output the centrality of each node; D. Quantify the safety of super high-rise construction machinery with the centrality of nodes Criticality of risk. The invention strengthens the maintenance and management of mechanical equipment and components based on the control of mechanical risk factors in the construction process of super high-rise construction projects, greatly controls potential safety hazards, and largely improves the safety level of super high-rise construction projects.
