结果发现：为了获得较高的产能，多分支井的井筒应垂直于最大主渗透率方向；对于给定的煤层气藏，存在一个最优的分支间距，既能保证较大的控制面积，又能保证分支间的互相影响；随着分支长度的增高，产气量也显著增大，但是考虑到煤层边界和井筒压降的影响，分支长度也应该有一个比较合理的值。

DIPSO incorporates the dynamic mutation, multi-subpopulations methods of IPSO, and changes the heights and the positions of the peaks by variable parameters and chaotic model. This algorithm uses multi-subpopulations to search for the highest peak in order to track the dynamic environments. Furthermore, DIPSO apperceives the changes of the environment by tracking the fitness value of the global optimal particle.

The Fe^0 concentration and pH had optimal values during the decolorization of X-BR in Fe^0-anaerobic biological system. When Fe0 dose, initial pH value and X-BR concentration were 400 mg/L, 7 and 100 mg/L respectively, the decolorization rate of X-BR in the integrated system could reach up to 90% after 68 h reaction. Compared with pure Fe^0 and pure microorganism treatment systems, it could be improved about 40% under the same experimental conditions. In addition, the analysis result of UV-vis spectrogram indicated that Fe^0 could promote effectively biodegrading of anthraquinone dye X-BR and its intermediate products.
