mixed bed

ORGANIC MATTER AND THE QUALITY OF THE DEFLUENT FROM MIXED BED Organic matter contents and parent materials of the soils.

土壤ph值、有机质含量、成土母质及农业利用方式等对土壤中微量元素的有效化有一定关系。

The pH of the effluent from the ion exchange mixed bed is in the range of 7.60 to 8.95. The copper tested before and after the small exchange column shows that the cooling water treated by resin has an obvious effect on restraining copper corrosion.

离子交换柱之前和之后的铜试片试验结果显示：交换柱前的内冷水具有腐蚀性，而经交换柱处理后的内冷水具有抑制铜导线腐蚀的功效。

EDI have prominent benefit of economy and environmental through contrasting with Ion exchange mixed bed.

通过与离子交换混床的对比,认为EDI技术具有显著的经济效益和环境效益.

Based on Stokes Law, settling velocity and ratio of settling velocity of cation and anion exchange resin in mixed bed are calculated and analyzed.

根据Stocks模型，对混床用阳阴树脂沉降速度、沉降比进行计算和分析。

The bed height of resin is 1. 2 m and the volume is about 2. 7 m3. In order to regenerate the exhausted resin out of the bed, the predesigned condensate polishing mixed bed regeneration process was used to regenerate the first exhausted resin.

树脂层高1.2m，体积约2.7m~3。为了对失效后树脂进行体外再生，采用预定的凝结水净化混床再生工艺条件对首次失效的混床树脂进行了再生试验。
