张华。氧化沟工艺处理低浓度城市污水的研究。

The paper discusses the change regulation, characteristics and designation function of the biological phase on the biological membrane of the organism contact - oxidizing system on the conditions of high concentration of NH3 - N and low concentration of BODS, and advices are given for the adjustment and supervision of the similar biological disposing system of industrial dirty water.

本研究探讨了在高浓度NH_3-N、低BOD_5条件下，生物接触氧化系统中，生物膜上生物相的变化规律、特点及其指示作用，以期为类似工业污水生物处理系统的调试与运行管理提供参考。

It takes about 50d for full-scale anoxic variable rate biofilter with microbe-catalyzed media to finish start-up at 22~28C. When influent flow varies between 485~737m3/d and HRT of biofilter between 7.7~5.0h (HRT of media layer between 3.9~2.6h), effluent COD is below 120 mg/L, SS is below 30 mg/L, and some of effluent BODs is slightly above 30 mg/L (the probability is about 40%) at normal temperature of 17~27C.

5以生物催化填料为载体的生产性缺氧变速生物滤池在22～28℃条件下50d左右完成启动过程；在17～27℃条件下处理城市污水，水量为485～737m~3／d，滤池HRT为7.7～5.0h(填料层HRT为3.9～2.6h)时，出水COD小于120mg／L，SS小于30mg／L，部分BOD_5略大于30mg／L(概率约为40％)。

Across the country, millions of tons of raw sewage, industrial waste and fertilizer runoff have turned lakes into algae-covered cesspools.

在全国许多地方，大量未经处理的污水、工业废水以及含有化肥残留的农田用水把众多湖泊变成了污水池，大片水面被藻类所覆盖。

All this comes as China grapples with a mounting water shortage. Across the country, millions of tons of raw sewage, industrial waste and fertilizer runoff have turned lakes into algae-covered cesspools. According to official statistics, more than half of China''s major waterways are so polluted that fish are dying or water is unsafe for drinking or irrigation. More than 300 million people -- almost one-quarter of the population -- lack access to clean drinking water, the government says.

所有这些问题都是在中国水资源日益短缺的大背景下出现的在全国许多地方，大量未经处理的污水、工业废水以及含有化肥残留的农田用水把众多湖泊变成了污水池，大片水面被藻类所覆盖从官方的统计数字看，中国一半以上主要河流的污染程度已经严重到了鱼虾绝迹或河水已无法供饮用和灌溉之用的程度

The experiments were made to study the effect of coagulation conditions and different coagulants on the results of restaurant wastewater treatment.

混凝条件对餐厅污水的处理效果的影响进行了实验研究，混凝剂聚合氯化铝的混凝净化效果优于聚合硫酸铁和硫酸铝。

Our series high efficient environment protect ore collects, furthers and depressors are worldwide used for non-ferric mines, such as gold, silver mines, Cu-Mu mines, Lead-Zn mines, coal and black lead mines as well as a kind of waste water treatment agents.

其生产的系列新型高效环保捕收剂、起泡剂和抑制剂广泛应用在贵金属矿、铜钼矿、铅锌矿、焦煤和石墨矿浮选流程以及矿山工业污水环保处理等领域。

According to the analysis of the virtues and defects of the traditional filers,the structure and characteristics of the pipe-cone shape filter are analysed in the article.

填料是生物接触氧化反应器的核心部分，本文从传统填料的优缺点入手，分析了管锥形填料的结构和特性，并对管锥形填充床对污水的处理性能进行了试验验证。

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.
