摘要： A method for reducing the aqueous dispersion present in the amalgam being fed to a mercury cell which comprises reducing the velocity of amalgam stream at one or more stations along the amalgam flow where the amalgam enters a substantially static pool of amalgam which is itself covered by a layer of an aqueous phase, e.g., at lutes located at the exit of the cell, the exit of the denuder, the entry to a pump tank or pump, and the entry to a wash box feeding to the cell. The invention is advantageous for reducing chloride entrainment in the amalgam fed to the denuder and for reducing the build-up of thick mercury deposits on the baseplate of a mercury cell.
摘要翻译：一种减少汞汞池中汞含量降低的方法，其包括在汞齐进入一个基本上静态的汞齐池的同时降低汞齐流的一个或多个站的汞合金流的速度，水相层，例如在位于电池出口处的琵琶，溶解器的出口，泵罐或泵的入口以及进入电池的洗涤盒的入口。本发明有利于减少进料到脱水器中的汞齐中的氯化物夹带和减少汞电池底板上厚汞沉积物的积聚。

摘要： A wastewater treatment system comprising one apparatus (1) for de-nitrification and effluent solids removal, another apparatus (2) for biological main treatment, and a further apparatus (3) for solids removal (5), each apparatus including a volume (40) in which each process is performed, a media-retaining sieve (6) at the volume (40) and arranged to retain buoyant media particles (4) in the volume (40), and a gas sparging device (8), (9) which is located in a lower end region of the volume (40) and which is controllable by way of valves (11) and (15). The three volumes (40) are substantially (10) identical to, or multiples of, each other, the three sieves (6) are substantially identical to each other, and the three sparging devices (8), (9) are substantially identical to each other. The gas is sparged into the main treatment bed at a lower flow rate for wastewater aeration but intermittently at a higher flow rate to disrupt and clean the bed. In a preferred embodiment it is possible to use relatively small media particles because of the provision of the in-situ cleaning arrangement. The biological main stage comprises up to four treatment stages either in internal partitions or in separate tanks.
摘要翻译：一种废水处理系统，包括用于脱硝和排出物固体去除的一个装置（1），用于生物主要处理的另一装置（2）和用于固体去除的另一装置（3）（5），每个装置包括体积（40 ），其中执行每个过程，在体积（40）处布置成将浮力介质颗粒（4）保持在体积（40）中的介质保持筛（6）和气体喷射装置（8），（9 ），其位于容积（40）的下端区域中，并且可通过阀（11）和（15）控制。这三个体积（40）基本上彼此相同或相等，三个筛子（6）基本上彼此相同，并且三个喷射装置（8），（9）基本上等于彼此。气体以较低的流量喷射到主处理床中，用于废水通风，但以更高的流速间歇地吹入并清洁床。在优选的实施方案中，由于提供了原位清洁装置，所以可以使用相对较小的介质颗粒。生物学主要阶段包括内部分区或分开的罐中最多四个处理阶段。

摘要： An activated sludge system for the purification of wastewater includes a membrane reactor comprising: (i) an array of pairs of vertical membranes (14) parallel to each other, (5) the membranes being spaced apart from each other and being permeate to liquid but substantially impermeable to solid particles, (ii) liquid flow channels between the membranes (14) of each pair, (iii) a liquid-collecting channels communicating with the liquid-flow channels for receiving liquid which has permeated through the membranes (14), and (iv) gaseous fluid sparging ducts (5) allocated to and co-planar with the respective pairs of membranes (14) and extending substantially horizontally for introducing gaseous fluid into a mixture of the liquid and the solid particles about the array, so that the gaseous fluid rises through the gaps (8) among the outer major surfaces of the membranes (14), each of the ducts 5 having therealong only one row of sparge holes (6), those holes (6) being downwardty directed for emitting the gaseous fluid downwardty.
