To study the performance of photocatalystic reactor, we designed and made the experiment rig that is fit for sewage treatment. Considering practical applications, we have discussed the optimum inclination for flat photocatalystic reactor. Under the condition of lack solar radiation fact survey date founded on wave band, the suggestions to determine the optimum inclinations for flat solar collector are given. In the experiments of degradation of dye, Congo red and Methylene blue dyes were taken as targets' contamination.

在光催化反应器的研究中，我们在现有的基础上，自行设计制造了适合于草酸铁/过氧化氢体系污水处理的平板型光催化污水处理实验装置；考虑到今后的实际应用，还对其最佳倾角问题进行了讨论，在缺乏长期太阳分波段辐射实测数据的前提下，建议平板型光反应器采用平板太阳能集热器的最佳倾角。

The bioinformatics analysis showed that the gene had the highest homology with the gene of Penicillium janthinellum, which reached up to 76%. The first 26 amino acids might be a signal peptide sequence with the hydrophobicity of up to 2.63. The CBHⅠ gene consisted of the catalytic domain, convergence zone and cellulose-binding domain and its tertiary structure was mainly composed of 3-sheets.
