The results of the studies show encouragingly that such systematic using of these costing methods does work in including much more information about costs incurred in the whole city sewage treatment system, distributing costs to different product lines, and then find the society costs of treating some single infectant in the city sewage.

根据研究结果分析，以上三种方法的综合运用，可以在理论上将整个产品生命周期中的相当大的部分的环境成本列入污水处理系统的成本核算，将其以合理的方法分配至各种不同的产品线，以此得出某污染物处理的社会成本数据。

This article mainly explains the safety principium of infectant factors in waste water vented by the paper making industry in China. Through the study on the experiment in open country and indoors with soil pole, indicating that it is a complicated process of biochemical degradation to form a layer, which has a biochemical capability to process COD degradation in polluted water from paper making industry.

综述我国造纸业污水中的污染因子危及地下水水质安全的机理，通过对野外试验和室内土柱试验的过程及结果进行分析研究，表明在包气带中形成一个以生物化学作用为主的生化层在造纸污水中COD降解是一个复杂的生物化学降解过程；生化层在天然状态下形成，由生物氧化带和生物氧化还原带形成，其形成过程具有明显的阶段性；只有当生物氧化还原带形成后，生化层才发育成熟，具备对COD降解的生化能力；生化层空间分布，仅局限在污水池、渠底部包气带中有垂向渗流的部分。

There is no residual infectant in the disposal system and we don't need a special device to deal with the infectant, also don't need special medication to sterilize and then we can get the standard water finally.

KY系列污水处理药剂与设备，通过将功能不同的多属种微生物共生共存于特殊载体上，能有效分解去除生物分解性差，分解速度低的有机物以及有毒恶臭物质，无需设置污泥处理装置，无需加药消毒，出水可达到中水标准。

However,as a kind of infiltration media , it played a important role in the treatment of wastewater.

但是，天然砂作为渗滤介质，在实际污水处理中将起着重要的作用。

Daily influent quantity forecasting plays an important role in the design and operation of a sewage treatment plant.

水量预测对污水处理厂的设计、运行具有非常重要的作用。

The H value was calculated to be 0.246 using Shannon-Wiener diversity index method.By aquatic reservoir evaluation criteria, combined with the type and density of zooplankton,it could be clearly determined that the water quality was seriously polluted and eutrophic.4.Comprehensive assessment of water quality:Affected by the influxion of sewage, slow flow velocity,high contents of nitrogen and phosphorus,the quantities of both zooplankton and phytoplankton at 1st point were relatively high,with the appearance of various indicator species of water pollution.

计算Shannon-Wiener多样性指数法得出H值为0.246，通过水库水生生物评价标准，结合浮游动物种类和密度，可以很清楚判定水质为污染严重，已经呈富营养化。4水质综合评价：排污口1号采样点受生活污水的大量排入的影响，且水流流速缓慢，水中氮磷含量高，因而浮游动物和浮游藻类数量都很高，而且出现很多污染生物指示种，综合分析该水层水质属污染严重的富营养化。

This paper analyzes that the main reason of low injectivity of water injection wells is that the Sr 2+ in formation water reacts with the SO 4 2- in the Yellow River water to produce precipitate of BaSO 4 when the Yellow River water mixes with formation water.

该文分析了胜坨油田注水井吸水能力降低的主要原因是黄河水与地层污水混注时，地层水中的Sr2＋、Ba2＋与黄河水中的SO2－4反应生成BaSO4、SrSO4沉淀。

This method had been adopted by mass effluent treatment plant, because it was low innocuity and cleanliness, had great degradation capacity, and can almost degrade all kinds of organic substance.

该方法环保无毒、效果好、能降解目前世界上几乎所有的有机物，为目前绝大部分的污水处理厂所广泛使用。

The preparation technology of sludge adsorbent using sludge from sewage treatment plant by microwave-induced pyrolysis was investigated. Sludge was treated innocuously and beneficially through microwave chemistry technology.

本文采用微波化学技术，对微波诱导热解污水处理厂污泥制备吸附剂的方法进行了系统研究，实现了污泥的无害化和资源化处理。

Warehouses and freight yards shall be equipped with rat-proofing devices; all garbage, waste, waste water and dejecta at any frontier port shall be treated innocuously so as to keep the surroundings at the state frontiers.

仓库、货场必须具有防鼠设施；国境口岸的垃圾、废物、污水、粪便必须进行无害化处理，保持国境口岸环境整洁卫生。

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％。
