Here a simple technique for parametrization construction of 17/11 biorthogonal wavelet family is presented: first, the associated synthesis filter is formulated as one trigonometric polynomial represented by two free parameters; then the perfect reconstruction condition of the filter bank is reduced to one system of linear equations; finally the analysis filter is obtained by solving this system of linear equations. Thus, the exact free parameter expressions for the 17/11 biorthogonal wavelet filter banks are derived.

The result makes clear, 2 class give urban sewage plant on the molecular quantity interval that organic owner should center the dissolvability in water water in kDa, and the content of organic matter compares hydrophoby the element of content big; of organic matter measures hydrophily interval distributings different organic thing shows water to accept filter film flux and hold back rate having distinct effect, the organic matter under molecular quantity 2kDa causes accept filter film to appear water flux attenuation bigger, organic matter is held back rate is minor, the organic matter that amounts to 57.2%; element to measure 10 ～ 100kDa causes accept filter film to appear water flux attenuation gentlier, organic matter is held back rate is older however highest the organic matter that amounts to 73.8%; to kiss scanty sex to differ shows water to accept filter film flux and hold back rate having distinct effect, classics is right of velar surface obstruction determine, confirm cause film to appear water flux and the main material that hold back rate change to be hydrophoby material, and the change that hydrophily material causes is minor.

结果表明，城市污水厂二级出水水中的溶解性有机物主要集中在kDa的分子量区间上，且疏水性有机物的含量比亲水性有机物的含量大；分子量区间分布不同的有机物对纳滤膜透水通量和截留率有着不同的影响，分子量2kDa以下的有机物引起纳滤膜透水通量衰减较大，有机物截留率较小，达57.2%；分子量10～100kDa的有机物引起纳滤膜透水通量衰减较平缓，有机物截留率却较大最高达73.8%；亲疏性不同的有机物对纳滤膜透水通量和截留率有着不同的影响，经对膜表面阻力的测定，证实引起膜透水通量和截留率变化的主要物质为疏水性物质，而亲水性物质引起的变化较小。
