This article researched on the result of dealing with three experiment waste liquid in activated carbon and kieselguhr respectively and discussed on the absorb result of absorbing probed into different condition of absorbing.

采用静态吸附法研究活性炭和硅藻土对3种实验废水在不同吸附条件下(吸附剂量、时间、pH值)的吸附效果。

Therefore any level of process intensication is not going to avoid the presence of lignin and hemi-celluloses in the wastewater.

因此，任何集约化水平的过程中不会避免的存在木质素和半纤维素的废水。

The key of paper industry sewage treatment is the efficient treatment of lignin.

造纸工业是对环境污染非常严重的行业之一，治理造纸废水的关键是对木质素的有效处理。

The system is continously operated for two months and the efficiency follows: 65-68% COD〓 reduction, 89-92% BOD〓 reduction, 58-62% TOCl reduction.(The condition of treatment: 35℃-39℃, pH4. 0-4. 5, gas-water ratio: 15-20: 1, retention time: 8-12hr). After the bleaching effluents are further floculated by limewash, the drain away water basically has accorded with the national effluent discharge standard.

控制温度35℃-39℃、pH值4.0-4.5，添加少量简单的营养物、保持15-20：1的实际气水比，接触停留时间8-12小时，连续运行两个月，COD〓去除率保持65-68%，BOD〓去除率89-92%，TOCl去除率58-62%；用石灰水进行混凝后处理，可进一步去除70%COD〓、脱色率90%，SS去除率95%，排水清亮，基本达到国家废水排放标准。

Mixed the redundant portion of it and other waste water, joins the sodium hypochlorite, limewater and polymerization aluminum chloride coagulant mix precipitates, could discharged after reaching the standards.

It is found that there is a linear relationship between CODcr and BOD5 of chemical wastewater.

化工废水的COD与BOD5之间具有相关性，存在着线性关系。

Process of biochemical wastewater treatment, general situation and operation after improvement of liquefied petroleum gas storage site are narrated.

文章简单介绍了液化石油气储灌场的废水生化处理的工艺流程、造后的工程概况和操作运行。

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。
