The anaerobic produced biogas is removed the H2S through desulfurization tower, wiped off water by dewatering device in biogas tank, and then enters into the generator.
厌氧产生的沼气经过脱硫塔除去沼气中的H2S，进入沼气柜后经脱水器去除沼气中的液体水，然后进入沼气发电机发电。
Dewatering becomes a major operation when the excavation lies below the natural water table and intercepts the groundwater flow.
当挖方位于天然地下水面以下时或有地下水流经时，排水就成为一个主要的工序。
When this occurs, dewatering and stabilizing of the soil may be accomplished by trenches, which conduct seepage to a sump from which the water is pumped out.
出现这种环境时，排水和岩土稳定可以靠地沟完成，地沟将水引入集水池中后再扫除。
