人工湿地芦苇床污泥脱水和稳定化技术因其能耗、运行篱理费用低得到更多的研究。试验污泥为厌氧池加氧化沟工艺二沉池污泥，模拟人工湿地进泥负荷为0．658kgTS／m2．d．进泥中TS和VS平均含擐分别为19．68和6．93g／L，pH为6．78。试验期为1年，对第一个进混周期后的渗滤液中COD、NH4-N及Ts的含最进行了测定。试验结束后，湿地中表层和底部污泥TS含量分别达到51．5％和56．8％，底部污泥中VS含量降至12．3％。结果表明，人工湿地芦苇床对城市污泥有较好的脱水和稳定化效果。

Constructed sludge drying reed bed emerge as a promising sustainable technology for its low operation and maintenance investment, dewatering andmineralization of biosolids, production of a beneficial and well-composted by-product. The experimental sludge was from secondary tank with anaerobic pond and oxidation ditch biological treatment processes. The sludge loading rate was 0.658 kgTS/m2.d and the system was monitored for one year. The average TS and VS content is respectively 19.68 and 6.93 g/L and the pH was 6.78. The change of COD, NH4-N and TS in percolated fluid for the first cycle was ...
