Abstract: The disclosure discloses a method for preparing biochar from Enteromorpha prolifera and use of the biochar. The method includes: subjecting Enteromorpha prolifera to lyophilization, then impregnating lyophilized Enteromorpha prolifera with phosphoric acid, and drying to a constant weight; grinding a dried mixture in a mortar, and then subjecting a ground sample to activation treatment in a tube furnace at 400° C. to 1,000° C. under a nitrogen atmosphere; and boiling an obtained solid product with concentrated hydrochloric acid, then washing with ultrapure water, and drying to a constant weight to obtain Enteromorpha prolifera biochar. The biochar is used in adsorption of cadmium. The method for removing cadmium using Enteromorpha prolifera biochar provided by the disclosure exhibits an extremely high adsorption and removal capacity for cadmium, with an adsorption capacity of biochar up to 250 mg/g or more.

Abstract: Disclosed is a method for calculating combustion in the bed of a waste incinerator. The method is based on a model of combustion in a waste incinerator bed and comprises a water evaporation model, a volatile matter analysis model, a volatile matter combustion model, and a fixed carbon combustion model. The volatile matter of the volatile matter combustion model comprises CO, H2, CH4, NH3, and H2S. The volatile matter combustion model comprises a combustion reaction equation for said volatile matter and O2, and respective equations for CO and CH4 reacting with water vapor. Equations governing the model of combustion in the bed of a waste incinerator comprise a continuity equation, an energy equation, a momentum equation, and a component equation. Boundary conditions of said governing equations comprise: equations of heat transfer and mass transfer from an upper boundary layer of the bed to the exterior; and equations of heat transfer and mass transfer from lower boundary layer of the bed to the exterior.

Abstract: The invention discloses a high voltage rechargeable Zn—MnO2 battery. The structure of the Zn—MnO2 battery includes zinc electrode/alkaline electrolyte/ion exchange membrane/acid electrolyte/MnO2 electrode. The ion exchange membrane comprises a cation exchange membrane, an anion exchange membrane or a proton exchange membrane. According to the invention, by using a composite electrolyte system (alkaline electrolyte/ion exchange membrane/acid electrolyte), a high voltage rechargeable Zn—MnO2 battery is obtained. According to the invention, an open circuit voltage of up to 2.7V is obtained, greatly improving the discharge voltage, and at the same time increasing the discharge capacity and enabling cyclic charge and discharge. The invention is of great importance in science research, beneficial to society and economics.
