The results indicate that the mass size distribution of fly-ash particles in the inlet of the WFGD system is typically disturbed bimodally, the peaks are approximate at 1 and 3 μm. And the shape of particles is regular sphericity, the mass ratio of PM2.5 to PM10 is about 0.434. The total mass concentration is about 85 mg/m3. In the outlet of the WFGD system, the mass size distribution of fly-ash particles is also bimodal. The proportion of fine particles increased, the mass ratio of PM2.5 to PM10 is about 0.764. Some fine particles are conglutinated and formed irregular agglomerate. The total mass concentration is under 23 mg/m3, the removal efficiency of total particles is 74.5%. The size removal efficiency is decreased observably with the range of particle size decreasing.

The beach body of Lower Triassic Feixianguan Formation in northwestern Sichuan can be divided into platform marginal oolitic beach and intraplatform point beach. The water is relatively deeper at the forming of most of platform marginal oolitic beach which is not transformed by the diagenesis of fresh water and mixed water and has poor reservoir properties. However, a part of oolitic beach formed under shallow water environment, and it is transformed by the diagenesis of fresh water and mixed water and well dolomitized, which can form excellent reservoir.
