Rough set and neural network have been used in fault diagnosis for many years, rough set is used to make the reduction and neural network is utilized to learn rules and approximate the ideal data.
In this paper, the fault sample reduction is done by the steps are as follows: The binary relation is established and judged according to the sample data, and then the suit rough set model could be founded.
One reduction is selected as the inputs of the network from the three reductions, and the decision is the output.

The particle swarm scale is configured to 80; the particle dimension is configured to 16; the maximum iterating times is configured to G=200; parameter c1=c2=2; self-adapting inertia =0.5; the maximum speed Vmax=0.3, the network optimized by the PSO is trained with the reduction data, and the test is simulated by the other 40 fault samples, the contrast is listed in Table 4.

Analysis data show that the addition of Ce improves the reduction performance of Fe-Mn species.
Manganese and Cerium compounds are also effective in selective catalytic reduction with NH3 [3, 4].
Analysis data from XRD, BET, XPS, TPR and TEM have provided the insight into the surface and structure properties of Ce-promoted Fe-Mn oxide catalysts compared with the undoped catalyst.
The peak at 405 ˚C can be related to a process of the reduction of Fe2O3 to Fe3O4, while the other two H2-consumption peaks with the reduction of Fe3O4 and FeO, respectively.
Effect of Ce doping on surface area for Fe–Mn oxide Sapmles BET surface area (m2 /g) Pore volume (cm3/g) Fe-Mn oxide Fe-Mn-Ce oxide 58 64 0.212 0.243 From the listed data, it is deduced that Ce-doping result in the increasing of surface area, pore volume of the Fe-Mn samples.

Research background
Data reported by the Ministry of Housing and Urban-Rural Development of the People’s Republic of China(MOHURD) shows that 3513 wastewater treatment plants have been put into operation in China by September 2013[1].
Literature search and on-the-spot investigation show that the study on the way of concentrated activated sludge reflow used in energy saving and consumption reduction at home and abroad is still back.
Feasibility of concentrated activated sludge reflow process used in energy saving and consumption reduction of small and medium-sized wastewater treatment plant is verified through comparing water quality and technical indicators.
Pilot effect of concentrated sludge reflow instead of secondary settling tank reflow used in energy saving and consumption reduction Based on laboratory study, the author selected two wastewater plants as the pilot unit.
The data of operation for 20 days shows that effluent quality initially fluctuates significantly and tends to be stable in later period.

Abstract.
The Dimension Reduction method based on M2DPCA and PCA The dimension reduction method based on M2DPCA and PCA is implemented as follows: The Training Phase: At the beginning of the M2DPCA,we can divide the sample of the face which the size of the sample is m×n into several parts, and the number of the part is p×q.
Ci composes the vector C which is saved in the face recognition data library.
And it can increase the redundancy of the data .It can result that when we use the minimum distance classifier, the minimum will be changed.
The data in table 1 indicates that the recognition rate of the method of three kinds of block have no difference.
