Reducing the nutrient quantity released by sediment through manipulating the periodfor digging up sediment is necessary to enhance removal ability of HBFM for dissolved nitrogen and phosphorus.
因此合理控制底泥清除周期减少底泥释放量，是提高HBFM溶解性氮、磷去除能力的重要途径之一。
2
The influence factors forremoval efficiency sorting by priority are hydraulic loading period, the appending quantity of EM rejuvenation, soil depth.
影响各污染物去除效果因素的主次为，水力负荷周期、EM投加量，土层厚度。

During the build-up period, Exhibitors and their contractors will be responsible for the daily removal of construction and packaging debris off site.
