摘要尝试采用上向流粗滤，作为慢滤池的预处理。 - The result showed that it conformed to the actual condition of the field to determine the decomposing and retention rate of the organic material with the method of nylon bag - potassium dichromate , so it ' s suggested that the relative study being performed with the method to replace the method of sand filtration tube - potassium dichromate
结果表明，在潮土区用锦纶袋重铬酸钾容量法测定有机物料腐解残留率更符合田间实际情况，建议用该法替代砂滤管重铬酸钾容量法进行相关研究。 - Suspended solids including fine particles and colloids cannot be removed efficiently with gravitation sedimentation ; they are removed using centrifuge , dissolved air flotation , diatomaceous earth filtration , coagulation sedimentation plus rapid sand filtration while dissolved solids are removed with ion exchange , ultrafiltration , activated carbon adsorption and chemical oxidation
悬浮固体之去除包括微颗粒及胶体物，无法以重力沉淀之物质，可采用离心分离机、空气浮除法、矽藻土过滤法、混凝沉淀加快滤池等去除之。而溶解性固体去除则采用离子交换法、微细孔滤膜过滤、活性碳吸附以及化学氧化等去除之。
