与其它设备的充氧特性和经济性能比较，该曝气设备的充氧能力和氧利用率都相当大，为其处理高浓度污水提供了必要的保证，动力效率也满足一般要求，具有较大的研究价值。

3The ratio of TN:TP of the water treatment system ranged from 5.3～20.6,which satisfied with growth need of filamentous periphyton to effectively absorb nitrogen,phosphorus contaminants.

3丝状周丛藻类处理系统的进水TN：TP介于5.3～20.6，达到了藻类生长所需的适宜范围，从而促使丝状周丛藻类较好地吸收污水中的氮、磷污染物。

6Unicellular periphyton has also shown good adaptability to sewages,with remarkable increases of Chla(58.2%)and biomass (54.0%).It was also observed that community compositions were successfully changed from original unicellular Bacillariophytes and chlorophytes dominated community to filamentous and unicellular Cyanobacteria dominated community.

6水质处理期间，颗粒态周丛藻类也表现出对污水环境很好的适应性，其Chla在整个试验期间增长了58.2%，生物量增长了54.0%，群落组成由试验初期的颗粒态硅藻、绿藻为主，转变为试验后期的以丝状和颗粒态蓝藻、绿藻为主的藻群，水绵、丝藻、纤维藻、颤藻等藻类大量出现。

After a residence time of 24 hours, the effluent is removed from the oxidizers, the sludge is allowed to settle out and the clarified liquor is discharged to sewer.

在处理24小时后，将污水从氧化池中排出并把泥浆沉淀掉，清澈的液体就可排放了。

Waste heat and treated sewage efflunents are two such discharges that are now being investigated.

废热和处理过的污水，就是目前正进行研究的两种排放物。

Walnut shell filter and ultrafiltration equipment were used to eliminate the suspended solid, suspended particles and oil in the oily wastewater.

采用核桃壳过滤器－超滤装置组合工艺处理油田含油污水，可以实现含油污水的油、悬浮物和颗粒的去除。

Domestic economy development needs reliable and steady power supply.Introduced in this article is a system technology, which adopts treated middle water as the make up water of evaporative cooling tower of the direct air-cooled power station, to reduce the backpressure of the vapor condenser and therefore to increase the maximum generation capacity, to reduce coal consumption as well as to re-use of sewage.

国民经济发展需要电力的可靠稳定供给，本文介绍了一种利用经过处理的中水，作为直接空冷电站夏季辅助蒸发式冷却塔的补水，从而实现降低空冷电站夏季凝汽器背压，提高峰荷出力，节约煤耗，同时又实现污水回用，所以是一个节能又节水的系统技术。

This design mainly handles industrial sewage for the red Feng City treasure mountain industrial park, this industrial park appeared a light soil sand of degree to turn phenomenon, water was the check and supervision local ecosystem environment to improve of to close an important condition.

本设计主要为赤峰市宝山工业园区处理工业污水，此工业园区出现了轻度的土壤沙化现象，水是制约当地生态环境改善的至关重要的条件。

It was hard to treat and make it reach the national standard for reuse water or discharge water with conventional treatment processes and equipments. Waste water containing hydrolyzed polyacrylamide was treated with gas flotation and the biological touch oxidized method.

用气浮＋生物接触氧化法对孤岛油田含聚污水进行处理，首先利用气浮去除悬浮油和大部分聚合物，然后利用生物接触氧化膜上的烃类降解菌和聚丙烯酰胺降解菌组成的高效降解菌群的生物降解作用去除乳化油和残余的聚合物。

Products are widely used in environmental, chemical, petroleum, pharmaceutical, sugar refining, metallurgy, food, ceramics, starch and other industrial waste water purification and sewage treatment.

产品广泛应用于环保、化工、石油、制药、制糖、冶金、食品、陶瓷、淀粉等各种工业废水和生活污水的净化处理。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
