废水

Sewage treatment comes in two stages - primary and secondary treatment.

中文解释=废水处理包括两个阶段，即初级处理和二级处理。

Specifically, currently a vast number of factories have been discharging the contaminated liquid into the primitively pure rivers and lakes, which fiercely undermine the quality of water resources.

说的具体一些，当前大量的工厂废水排放到原本清澈的河水湖水中后，严重地影响了水资源质量。

As it shows some special physical and chemical pro -perties, it is used in wastewater treatment.

由于具有一些十分特殊的物化性能，近年来被人们应用在废水处理中。

So, the feasibility of the treatment in technology and economy seems to be prodigious.

罐头生产废水的处理在技术和经济上都具有很大的可行性。

Up-flow velocity is one of the key factors affecting the granulation of sludge. Experiments results showed that there are two specific sludge mixing phenomena in ABR. One is roll suction and the other is purl trundle. They can weaken the need for up-flow velocity and accelerate sludge granulation in ABR.

通常情况下，上升流速是影响废水厌氧处理过程污泥颗粒化的重要因素之一，本研究中发现ABR具有卷吸和翻滚两种独特混合现象，这不仅削弱了反应器对水流上升速度的要求，而且大大加快了污泥颗粒化进程。

In pyrite resources exploration there are environmental pollutions such as acid wastewater 、slags and dusts and so on.

硫铁矿资源在开发利用过程中，会引起酸性废水、固体废物和粉尘等污染。

Application of pyrites in coal gangue in treatment of wastewater containing Niwas studied.

在煤系硫铁矿在处理含镍废水中，废水的pH值，反应时间，粒度，加入量，温度，搅拌等对Ni2+的去除率影响较大。

With pyroxy as an adsorbent,the adsorption of pyroxylin for phenol in sewage,the rate of adsorption,the capacity of adsorption and the effect of pH on the adsorption of phenol were studied.

本文所用焦木素是以造纸黑液提取的木素为原料制备的，其吸附性能与活性炭类似，其原料来源丰富，价格低廉，且可利用废物，将其应用于含酚废水的处理，达到以废治废的目的。

Therefore, the rapid oxidation of pyrrhotite contributes to a great extent to the contamination of environment in tailings through the production of acid mine drainage AMD. In order to ...
