查询词典 sewage disposal

At present, there are lots of methods used in sewage treatment, the flocculation is one of the most common and economic techniques.

目前，用于污水处理的方法有很多，而絮凝处理是污水处理方法中最常用、最省钱的工艺之一。

The synergism of inorganic coagulation agents and organic flocculator,i.e.serious of polyacrymides,in sewage treatment was investigated.

混凝法是废水处理中应用最多的方法。影响其处理效果的主要因素是药剂的选用和使用方法。

This article focuses on introducing the research of chitosan and its derivatives in water supply, industrial wastewater,sewage, sludge, food industry and the medicine production in recent years and looking ahead to the chitosan as a flocculent in future.

本文着重介绍了近年来壳聚糖及其衍生物在给水、工业废水、生活污水、污泥及食品、医药生产中的应用研究，并对壳聚糖作为絮凝剂的研究进行展望。

It was shown that coagulating that fluoric wastewater with PFS brought about a good result,and that the optimized condition s coagulating that sewage .

结果表明：该含氟废水用PFS处理可以收到良好的除氟效果；室温下混凝处理的最适宜条件是：pH=7。

We can see that the performance parameters in exactly the same circumstances, the submersible sewage pump horizontal axial force than the average, to a large pump, and the balance of the difficulty is harder than the vertical pump.

可以看出，在性能参数完全相同的情况下，潜污泵的轴向力比一般卧式泵要大，而平衡难度比立式泵要难。

The bad flow pattern will make the efficiency of the pump unit drop. Meanwhile, because there are a lot of sediments in sewage in the forebay , the bad flow pattern will make sediments depositing freely and the sediment deposition will cause worse flow pattern.

同时，由于排污泵站进水水流中含有大量的悬浮固体颗粒，不良的前池流态会使泥沙更容易在前池淤积，而泥沙淤积又进一步加剧了前池流态的恶化。

In city , because the occupied area of the urban sewage pumping station is usually limited , the length of the forebay is inclined to be short and the diffusion angle in flow direction is big accordingly , which causes bad flow pattern, such as backflows ,vortices, etc.

城市排污泵站由于条件的限制，前池一般面积较小，扩散角较大，扩散段较短，因此水流进入前池后突然扩散，流态紊乱，易行成回流、漩涡等不良水流流态，从而影响水泵的工作性能。

In order to protect the limited freshwater resource of our country, we should develop the work of sewage water treatment.

为了保护有限的水资源，保证国家可持续发展的战略，必须大力发展我国的污水处理事业。

Dynamic experiments of domestic sewage treated by electrocoagulation process with triangle-wave power, sine wave power and full-wave rectifier power, which had the different power waveform and waveform frequency, were studied. And the removal characteristics of organic pollutants were studied.

采用三角形波电源、正弦波电源、全波整流电源进行动态实验，研究采用不同电源波形和波形频率电源的电凝聚对处理生活污水的影响，以及对有机污染物的去除特性。

Sewage into the Ganges, the two sides in 80% of the living water, 15% is industrial waste water.

到恒河，在80％，生活用水双方污水，15％是工业废水。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
