Abstract: Ferrate refers to the highest state of iron for + 6 price of the corresponding oxygen acid salt, the oxygen acid salt inherently a performance is very superior strong oxidizer, in modern economic society construction in the process of development, has a good application prospect. Based on the actual situation, with electrolytic method for high purity high iron potassium process as the research object, the high purity high iron potassium structural properties, preparation method, electrochemical method for high purity acid potassium high iron the influence factors of these four aspects to discuss how to use electrolytic method for high purity high iron potassium process more detailed analysis and explained, and then demonstrates the power needed to prepare high purity in high iron potassium process preparation is more superior than other ways of performance.

Abstract: The high cost of the raw materials and non-recycling use are the two main problems which restrict the development and extension of the SLS rapid prototyping. Firstly this paper did some theoretical analysis on the characteristics of wood flour, hot melt adhesive and other components. Then, through experimental comparison, using SEM to do microcosmic study and actual processing in laser shaper, this paper got a new formula of WPC for SLS. It is proved by the experiments, the WPC according to this formula is green environmental protection, degradable and can be recycled. Also, it can meet the processing requirements of SLS. The shape precision of the formed parts is high, the relative warping rate is only 0.26%~0.45%, the roughness is less than 0.03mm, and the parts reached a certain mechanical index. The tensile strength can reach a maximum of 0.014MPa and shock strength can reach a maximum of 0.954kJ/m . It provides the basis for the further post-processing to enhance the mechanical properties.

Abstract: In this work the use of Membrane Bioreactors to treat leachate effluents is discussed. The problem of membrane fouling is addressed, and some of the efforts being done to overcome this problem presented. The process optimization requires the reduction of other parameters, some directly related to mass transfer, such as the total amount of solids, the total dissolved solids and the total suspended solids. The preliminary results obtained show the high potential of this technique for the treatment of leachates, mainly for the reduction of solids in leachate streams.
