图像影像image filtering A remote sensing term related to image enhancement that refers to the removal of a spatial component of electromagnetic radiation (与影像强化相关的遥感术语,指移除电磁辐射的空间成份。)
垃圾渗landfill leachate Liquid that has seeped through solid waste in a landfill and has extracted soluble dissolved or suspended materials in the process (填埋场中的通过固体废弃物渗透出的液体,此过程中的滤液含有可萃取的可溶性溶剂或悬浮物。)
微孔过microfiltration The separation or removal from a liquid of particulates and microorganisms in the size range of 0.1 to 0.2 microns in diameter (从液体中在直径0.1到0.2微米的尺寸范围内分离或者移除微粒和微生物。)
percolating water Subsurface water that passes, under the force of gravity, through rocks or soil along the line of least resistance (在重力下穿过岩石或土壤沿着最简便的方法渗透的表层下水。)
leaching 1. The process of separating a liquid from a solid - as in waste liquid by percolation into the surrounding soil. 2. Extraction of soluble components of a solid mixture by percolating a solvent through it. 3. To lose or cause to lose soluble substances by the action of a percolating liquid (1. 从固体(如废液渗透到周围土壤)中分离液体的过程。 2. 通过使用溶剂溶解,从固体混合物中提取可溶性成分。 3. 通过滤掉溶液失去或使失去可溶性物质。)
声器acoustic filter A device employed to reject sound in a particular range of frequencies while passing sound in another range of frequencies (一种用来过滤某个频率范围的声音同时允许另一个频率范围的声音通过的设备。)
filter cake Accumulated solids, wet or dry, generated by any filtration process, including accumulation on fabric filters in air filtering processes, or accumulation of wet solids in liquid filtering processes (累积的固体,干的或者湿的,由过滤过程产生,包括在空气过滤过程中累积的纤维物质或者在液体过滤过程中累积的湿固体物质。)
filtration Separation of suspended particles from a liquid, gas, etc., by the action of a filter (通过过滤把液体、气体等中悬浮的颗粒分离。)
trickling filter
trickling filter A system of secondary sewage treatment which is similar to self-purification action of streams; it is more accurately a biological oxidizing bed; the effluent is placed on the stones in the bed and microorganisms present consume the solids as a food supply (一个二级污水处理系统,类似水流的自我净化行为;更准确地说是一个生物氧化床;污水被置于池床里的石头上,水中存在的微生物吸食固体物作为食物。)
生物过biofiltration The distribution of settled sewage on a bed of inert granular material through which it is allowed to percolate. In doing so, the effluent is aerated thus allowing aerobic bacteria and fungi to reduce its biochemical oxygen demand (污水在惰性颗粒材料(通过它允许渗透)的环境中的分布。这样做可以使污水与氧结合,从而使好氧细菌和真菌减少它们生化需氧量。)
精致过polishing
ultrafiltration Separation of colloidal or very fine solid materials by filtration through microporous or semipermeable mediums (通过微孔或半透的媒介以过滤的方式对胶体或极细固体物质的分离。)
filter A porous material for separating suspended particulate matter from liquids by passing the liquid through the pores in the filter and sieving out the solids (一种通过让液体穿过过滤孔,留下固体物质,以分离液体中的物质的多孔材料。)
选择过selection filter
