对好氧锥形流化床膜生物反应器的启动特征、生物膜行为、特征和结构进行了详细的探讨,并与相近启动条件下的传统柱状流化床生物膜反应器的启动行为进行比较。

The styrene-acrylate spheres were coated with the TiO2 colloidal particles via electrostatic effect and hydrogen bond interactions with the increase of aging time, thus the film-forming capability of the solution was changed. The poor film-forming capability results in the formation of the porous structure with dense, homogeneous island morphology. Then the TiO2 porous films with dense pores can be obtained after two coating-dissolving cycles.

结果表明,TiO2溶胶与苯丙乳液混合后,陈化时间的延长有利于TiO2胶粒通过静电、氢键作用在苯丙乳液粒子表面形成吸附层,从而改变涂膜液的成膜性,形成较为密集、且均匀分布的岛状多孔结构,在此基础上经两次涂膜,即可获得具有致密孔洞的TiO2多孔薄膜。

The results show that the TiO2 porous films can be obtained by anode oxidation using 10% H2SO4, voltage of 120V on the surface of Ti-6Al-4V alloy, and the aperture size is about 100-200nm. The acerate CaHPO4 with size of 200-400nm can be gained by the electrochemical deposition. Ultimately, the acerate CaHPO4 changed to the sheet Ca10(PO4)62 after being treated with 0.1mol/L NaOH in autoclave at 200℃ for 10 hours .

结果表明:钛合金(Ti-6Al-4V)板经以10%的硫酸为电解液和电压为120V时阳极氧化,产生孔径大约为100-200nm的多孔氧化膜,再经电化学沉积,得到尺寸大小约200-400nm针状的CaHP04,最后经盛有浓度为0.1mol/LNaOH 水溶液、温度为200℃的高压釜中水热合成10h,针状的CaHP04 转变为片状的Ca10(PO4)62。
