In this research, we consider that the predominant bacteria in low temperature wastewater treatment in winter were cold-adapted microorganisms, the number of which increased as the temperature dropped more and more, but rarely high up to the number of mesophilic bacteria in normal temperature due to its low growth rate and the restriction of ecological factors, so that the total number and activity level of microorganism in activated sludge decreased.

随着污水温度的降低，污泥中冷适应微生物的数量逐渐增加，但由于冷适应微生物的生长速率相对较低，且容易受到各种生态因子的抑制作用，其数量无法达到常温下中温微生物的水平，使得污泥中微生物的总体数量和活性降低。

It has also been indicated from the digestion of mixed substrates that potato processing concentrate should be controlled between 20% and 50% of sludge dosage, pig blood lower than 10% or otherwise necessity for the extention of mesophilic digestion detention time from 10d to 14d, and sausage processing flotate around 10%.

试验结果表明，在混合基质的两相厌氧消化过程中，马铃薯加工废物的投加比例宜控制在20～50％；猪血的投加比例宜小于10％，否则应将中温消化反应器的停留时间由10d延长至14d；肠类加工废物的投加比例可控制在10％左右。

The features and mechanism of pollutant removal by microelectrolysis as well as the characteristics of UASB start-up were also studied by means of GC-MS and analyzing granular sludge.

通过GS-MS和颗粒污泥分析，分别研究了微电解对污染物去除特性和去除机理与UASB的启动特性。

Business card printing and membership card making Ink viscosity in business card printing and membership card making faster, rollers and plates after the ink friction heats gets smaller, on the rising of the ambient temperature, the viscosity of ink will drift away, this time using the innovativeink, with the temperature increase, decrease viscosity is referred to as a viscosity index of added value, that is, the viscosity index is a viscosity index of temperature-dependent, for example, at a low temperature solvent oil sludge formation, if you join methylmetacrylate and transfromer monosomic of multi-fault copolymer exclude this.

制卡和会员卡制作油墨的粘度在随制卡和会员卡制作速度的加快时，因墨辊与印版摩擦后油墨温度升高而变小外，当环境温度的上升后，油墨的粘度也会逐渐变小，这种在使用油墨时，随着温度的上升，其粘度下降的行为被称为粘度指数增加值，即粘度指数是表示粘度随温度变化的指标，例如，溶剂油在低温下形成淤浆时，如果加入甲基丙烯酸酯和极性单体的共聚物排除此类故障的发生。

The test results showed that base on the previous A/O activated sludge treatment technology,putting modified montmorilonite powder in the aeration basin would have good results to the waste water biological treatment and to the Nylon 66 salt industrial waste water treatment.

实验结果证明，在原有A/O活性污泥法处理工艺的基础上，曝气池内增加改性蒙脱石粉填料，对废水进行生物处理，处理尼龙66盐化工废水的效果更好。

Employing HP-8-8 polyacrylic resins as a porous multimolecular carrier for fixed cultivation of sludge,experimental investigation of wastewater treating was carried out by means of fluidization with biofilm sequencing batch reactor.

采用HP88型聚丙烯酸酯类多孔高分子载体对污泥实行固定化培养，以流态化方式进行生物膜SBR 废水处理试验研究。

A submerged membrane sequencing batch bioreactor was used to treat coke wastewater.Long running performance showed that due to the membrane interception,the nitrobacter is enriched in reactor in the interest of improving the nitrification rate;the maximum ammonia nitrogen loading can be 0.19 kg/(m3·d) with effluent ammonia nitrogen＜1 mg/L (removal rate 99%).Long sludge retention time may result in the accumulation of metabolic products and high molecular materials,and thus inhibiting activity of nitrate bacteria and causing a ccumulation of NO2-,which is beneficial to the running of short-cut denitrif ication.However,too long retention time will affect the activity of nitrite bacteria,detrimental to the treatment effect of ammonia nitrogen.

采用浸没式膜生物反应器处理焦化废水的试验结果表明：膜的截留作用可使硝化菌在反应器内富集而有利于提高系统的硝化能力，其去除氨氮的最高负荷为0.19kg/(m3·d)，出水氨氮＜1mg/L(去除率为99%)；泥龄长可能使微生物的代谢产物或其他大分子物质积累，从而抑制硝酸盐细菌的活性，导致NO2-积累而有利于短程脱氮的进行，但泥龄过长也会影响亚硝酸盐细菌的活性，从而影响对氨氮的处理效果。
