亚硫酸钙的溶解浓度对氧化速率有非常重要的影响，课题主要研究CaSO3的溶解特性，描述了CaSO3在不同条件下(温度、pH、溶解时间T、搅拌速度、初始加入量等)溶解量的变化规律，进而找出CaSO3的最佳溶解条件，以达到提高氧化速率及石膏的生成率，防止堵塞和结垢的目的。

Using first order plug-flow reactor model, BOD5 removal rate constants of the whole wetland system were estimated to be 0.50 1/day (at 24℃) and 0.76 1/day (at 24℃) in the start-up and stable phase, respectively.
