This paper summarizes the relevant research data at home and abroad in recent years, briefly introduces the functions of different kinds of nano materials, summarizes the application of nano adsorption technology in sewage treatment, and explores the adsorption mechanism of various nano materials on various pollutants in water, At the same time, the research progress of several common nano adsorption materials in removing water pollutants is summarized, and the risks existing in the application of nano materials are pointed out.
Graphene oxide is the product of graphene surface oxidation, which can be transformed into graphene after reduction.
The removal mechanism of heavy metal ions by nano zero valent iron includes reduction and adsorption.
When the standard electrode potential of heavy metal ions is lower than that of iron, adsorption mainly occurs; When the standard electrode potential of heavy metal ions is slightly greater than that of iron, adsorption and reduction work at the same time; When the standard electrode potential of heavy metal ions is much greater than that of iron, reduction mainly occurs.
Therefore, the surface area of zero valent iron is an important parameter to control the reduction rate.

Good fit is obtained between the predicted values by the microstructure model and the measured mill data, with an agreement generally within the interval ±15%.
Material and Experimental Procedure Commercial HSLA steels were used in this investigation and process data were collected from SSAB's hot strip mill.
In order to calculate the microstructural evolution of the material, the required process data is the soaking temperature in the reheating furnace, the reduction and rolling speed in each pass and the temperature.
As input data to the friction-hill model, measured process data, such as measured roll forces and geometry of the strip, were used.
For the 8 mm strip, the model gives an accurate prediction of the flow stress evolution compared to measured data.

The LCCP of water source heat pump is always lower than that of conventional electric water chillers plus gas direct-fired unit, and its carbon emission reduction rates up to 32.4% as compared to the latter.
Compared with GWP, CO2 mitigation rate could be more comprehensive for measuring the direct effects to climate warming and associated with the CO2 emissions reduction index directly.
The annual running primary energy consumption data of three candidate cold and heat source plans was shown in Table 2.
According to the data of literature [23] and [24], CO2 emissions generated from the unit electrical energy of coal power could be calculated about 0.822 kg / kWh.
LCCP composition of different cold and heat source plans (3) As compared to project 4, greenhouse gas emission reduction rate of project 2 is up to 32.4% in the full life cycle.

The assumption is, that corrosion leads to a reduction of the contact area and this leads to a local increase of the contact pressure between the joined sheet metals.
This data is then read in via a Python script and the normal vectors of the edge elements along the path of analysis are calculated.
For further investigations, the question is raised whether this leads to an increase or reduction of the load-bearing capacity of the joint.
We would like thank subproject A01 for providing the material data and tool geometries for the simulation model.

Laboratory studies confirm the convergence of the simulation results with the experimental data: solutions have been obtained to crystallize out cryolite (with fluorine and silica content of 50–53 % wt. and 0.11÷0.53 % wt., respectively), which is in demand in the electrolysis of cryolite-alumina melts.
This algorithm consists of two successive steps: choosing the component composition of the simulated system considering chemical analysis data obtained for the SPL components and alkaline solution; and preparing data to introduce into the model considering the solvent concentration and the L:S ratio.
Based on the chemical composition data of the average sample of the SPL carbon part, we determined a set of independent components and their concentrations in % wt. to introduce into the model as follows: 50.35 C, 17.51 ​​F, 16.44 Na, 6.77 Al, 1.49 Si, 0.33 Fe, 2.01 Ca, 0.65 Mg, 2.11 O, 0.86 S, 0.73 K, 0.10 Cl, and 0.06 Ti.
To verify the convergence of the SPL carbon part hydrometallurgical processing simulation results with practical data and to adjust the main process parameters, we have performed laboratory tests.
