废水

The orthogonal tests showed that electrolytic time was the most notable factor affecting the oil removal rate of the wastewater.

正交实验表明，电解时间是影响废水除油率的最显著因素。

It is inevitable to exist excessive water in the crude oil in the late exploitation of many outdate oil field and exploitation on the ocean flat. It is not valid to process oil very well without dealing with crude oil. It is necessary to have water-oil separation equipments for purifying and separating crude oil. Meanwhile, it is necessary to dispose oil from sewages to reach the national standard in the industrial sewage treatment, and the water-oil separation equipment is urgent need too.

在我国众多老油田开采的后期，以及海上石油平台的原油开采中不可避免的存在原油含水量较大，不经过处理无法有效的对石油进行深加工，亟需有效的液液分离设备对原油进行提纯和分离；同时在工业污水处理中也经常需要将废水中含有的油类去除以达到国家排放标准，这同样需要有效的液液分离设备。

We are mindful of keeping our environment clean and green and one of the major projects currently underway is to divert the disposal of our city's treated waste water from the city's estuary via an ocean outfall pipeline to 3km off shore.

我们一直非常关注保持城市的清洁与绿化。其中一个正在进行的重要项目就是通过一根入海河口管道从城市的河口将城市已处理的废水转移到3千米远的海岸。

The application of Fenton oxidative technology in wastewater treatment is attracting more and more attention.

Fenton 氧化技术在废水处理中的运用正得到越来越多的关注。

Since with depth oxidize method handling oily wastewater, it is a relatively new field, in addition many research works remain, is further to go on and perfect.

由于采用深度氧化法处理含油废水是一个相对新的领域，还有很多研究工作有待进一步的进行和完善。

In Part 2, handling the oily wastewater with depth oxidize method.

第二部分采用深度氧化法研究对含油废水处理情况。

The results showed that the wastes of zirconium oxychloride can be made into crystalline layered sodium disilicate with good properties.

结果表明，碱性废水和酸性硅渣为主要原料，可制备出性能良好的层状硅酸钠。

The machine can be used widely for oxygenizement aeration of projects of sewage treatment and wastewater reuse etc, and the projects of oxygenizement and reoxygenation of rivers, lakes and aquariculture etc.

该机广泛应用于各类工业废水及城镇生活污水的处理和中水处理等工程的充氧曝气、推流、搅拌气浮以及江、河、湖、泊的复氧工程和水产养殖等领域的充氧。

The whole process optimum conditions were determined as follows:pH of neutrality,10 V of electrolysis voltage,0.018 A/cm2 of electrical current density,2 h of ozonization, 250 mg/L of environment-protecting coagulant 1＃,3＃.

经大量工艺实验确定全流程工艺条件为：废水pH中性、电解电压10 V、电流密度0.018 A/cm2、电解时间2 h，O3氧化时间为2 h，混凝剂环保1＃和3＃浓度各为250 mg/L。

Based on the theoretical and practical combination, the cooperation function mechanism of the ozonization, activated carbon adsorption and biological degradation of the engineering bacteria in the treatment of the non-degraded organic wastewater was furthered, and a model for pollution removal by ozone immobilized biological filter was built, which provided the theoretical and scientific basis for the future further research and practical application.

文中首次从微生物生理生态学角度，研究了固定化曝气生物活性炭除污染效能和净化机理，在理论与实践结合的基础上，进一步研究了臭氧氧化、活性炭吸附与工程菌生物降解三者在难降解有机废水处理中协同作用机理，总结出臭氧固定化曝气生物滤池除污染模型，为将来的深入研究与实际应用奠定了一定的理论基础和科学依据。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
