The simulative results show that the leachates COD of semi-aerobic landfills decrease to National Discharge Standard Class I (100mg/L) in 2-3 years, and ammoniac nitrogen reduce to the standard (15 mg/L) in one year or so.

在室内模拟的条件下显示，准好氧填埋场垃圾渗滤液的COD自然衰减至国家一级排放标准(100mg／L)仅需2～3年，而氨氮只需1年左右即可达到相应的国家一级排放标准(15 mg／L)。

NO3-N is the most popular and safest nitrogen source to Spirulina, the suitable concentration is about 11mmol/L, which can speed the growth rate and reduce the cost of cultivation as well. NH4-N of the suitable concentration can enhance the growth of Spirulina,but overhigh concentration will cause the ammoniac toxicosis, the suitable concentration of NH4-N is about 1.27～2.57mmol/L.

NO3-N对螺旋藻是最为通用和安全的氮源，但添加浓度以11mmol/L左右最为适宜，既可满足藻体的最佳生长需求又可降低养殖成本；适宜浓度的NH4-N可促进螺旋藻的生长，浓度过高则会造成NH3中毒，NH4-N的添加量以1.27～2.57mmol/L范围最为适宜。
