污水处理

The two species of plants in eutrophication water can normally grow and develop. The removal rate of TN and TP of Canna indica and Cyperus alternifolius in eutrophication water was as high as 84% and 80%,77% and 72%, respectively.

结果］利用云南土著植物美人蕉和伞草在秋冬季节处理大清河污水具有良好的净化效果。2种植物在污水中均能正常生长发育。

A kind of reformed Carrousel 2000 A2C which was used to treat small town's municipal wastewater was studied in this thesis. It also introduces the designing parameters, sizes of the construction, pattern of operation and management and effectiveness of this technology.

本文以武清区第二污水处理厂为例，研究了改良Carrousel 2000 A2C工艺在处理小城镇城市污水的应用情况，并介绍了该工艺的设计参数、构筑物尺寸、运行管理模式以及工艺的应用效果。

In order to enhance the bio-nitrogen and phosphorus removal of the modified Carrousel oxidation ditch process,the treatment performance,the principle of bio-nitrogen and bio-phosphorus removal have been discussed,at the same time the influencing factors to the effluent quality have been analyzed from the operation practice for 3 years.

为了提高改良型Carrousel氧化沟工艺污水处理厂的脱氮除磷效果，结合某污水处理厂3年的运行实践，讨论了该工艺的处理效果，生物脱氮除磷原理及影响出水效果的因素。

The results showed that PPFS had better flocculating efficiency than PFS and PAC,the performance of floccule was the optimal at pH of 6~10.Furthermore,when PPFS could be used to treat municipal wastewater,the optimal dosage of PPFS was 4.8 mg/L,and PFS and PAC were 6.4 mg/L,the removal rates of CODCr we...

此外，将PPFS用于处理城市生活污水，PPFS除浊的优化用量为4.8 mg/L，而PFS﹑PAC优化用量为6.4 mg/L；CODCr的去除率可分别高达91.4%﹑88.4%﹑86.5%；在pH值为7￣9的条件下，PPFS对城市生活污水的浊度和CODCr的去除具有良好效果。

Shortage of water, pollution of tributary waters and incretion of sewage irrigation for farmland make the potentiality impact on environment and safety of agricultural products.

适当处理的城镇生活污水是一种稳定的水资源、在很大程度上缓解水资源的紧缺状况，利用污水资源的主要用途之一是灌溉农田。

According to basic analytical methods of environmental quality standards for surface water in China(GB3838-2002),we used the 2002-2006 monitoring data to evaluate and characterize water quality condition of Lanzhou reach of Yellow river,based on the Nemerow index and variance analysis of the mean square deviation.

根据2002-2006年黄河兰州段水质监测数据，按照《地表水环境质量标准》GB3838-2002中Ⅲ类水质标准，确定污染物的污染程度，选用内梅罗水污染指数法，运用方差分析，对黄河兰州段水质现状进行评价分析，结果表明：(1)黄河兰州段水体的主要污染物是粪大肠菌群和总氮；(2)大量未经处理的生活污水排放是黄河兰州段的主要污染源；(3)针对黄河兰州段生活污水污染现状，提出源头治污思路。

Certain sewage-treatment plants were damaged, and untreated sewage flowed into the river and then into Narragansett Bay, forcing a ban on shellfish-fishing throughout the state.

另外，一些污水处理厂也在此次洪水中遭到破坏，未经处理的污水直接排到河中，然后流入纳拉甘西特湾。现在，罗得岛全州范围内已禁止捡拾贝类。

We are now assessing the options for further treatment and outfall arrangements outside the harbour.

我们现正评核进一步处理污水的其他方案和在海港以外地方排放污水的安排。

Polyoxier utilizes paramagnetism of oxygen to adopt high gradient intense magnetic field to gather the oxygen of air; helimagnetizer adopts high gradient intense magnetic field to magnetize sewage and the capacity of water dissolving oxygen is increased after magnetization.

螺旋磁化器采用适当梯度和特定方向的磁性场对污水进行磁处理，使污水中的介质充分极化，磁化后的水溶解氧的能力得到增强。

However, there is large quantity of phosphorus in wastewater, which corresponds to 34.2% of the yearly phosphorite output in China.

污水中含有大量的磷，我国污水排放中的磷量相当于磷矿产量的37.5%，经过处理回收可以转变为磷资源，又可以保护环境。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
