废水

It is useful to reduce the occurance of acid mist by adding erosion retardant and surface activity into acid which has been used in some industries.in the developed province and city, the bureau for enviroment protection calls on all enterprises to process the heated zincification water and prohibit from drainage, all enterprises should process the rinsed waste water and plating-aid waste water,however it remains to be strengthened across the country for the process of three wastes come from heated zincification

在酸中添加缓蚀剂和表面活性剂可以减少酸雾的产生，已在一部分企业中得到应用。在发达省市，环保部门要求企业必须对热镀锌废水进行治理，不得外排，企业对漂洗废水、助镀废液均进行处理，但全国范围内对热镀锌的三废治理还需加强。

Partial blow liquir enter aerobe's wastewater treatment system with midcourse wastewater, which make midcourse wastewater to bigger and more complexity.

部分制浆废液随中段废水一起进入好氧生物处理系统，造成中段废水排放量更大，成分更加复杂，有害物质含量增加。

We carry on a processing to the oil extraction waste water, instead in return to affusion, then not only will they satisfy the affusion of water which increase increasingly in the process of the extraction of the oil-field, but also can save the water resources and reduce pollution of the environment, bring an economic performance for the oil-field, its advantageous to the oil-field can keep on a development.

试验后水质明显改善，符合辛一站的水质标准。本论文的实验研究工作在胜利油田辛一站进行，首先分析了辛一站的采油废水的性质，用悬浮污泥过滤法简称SSF和超滤膜过滤法2种方法，分别进行了辛一站采油废水处理试验。

Under the alkalescency condition, the changing of pH value effect the decompounding rate of phenol, along with the pH value accretion the decompounding rate decrease.

在BPBC处理苯酚废水的过程中，有中间体的产生，如果要彻底除去苯酚废水中的有机物，实际电解时间不宜小于30min。

The technical conditions for recovering cyanide from agrochemical waste water by liquid-film method is studied,and the various surfactants and kerosm as oil phase and alkine liquid as liquid phase affecting the cyanide waste water treatment are tested.Therefore, the oPtimum process conditions are determined.

研究了液膜法回收农药废水中氰化物的工艺条件，考查了以不同表面活性剂、煤油等为油相组分，碱液作内相的乳状液，对连云港市第二农药厂合氰废水的处理效果，确定了最佳的工艺条件。

Through the test,the optimal hydraulic retention time was found to be within 6h～8h,NH3-N increasing rate,within 90%~96%,and a new phenomenon of anaerobic ammoniation was found.

采用ABR工艺对肉类加工废水进行前期氨化处理，通过试验得到最佳水力停留时间为6～8h，氨氮递增率在90%～196%之间；同时发现了厌氧氨氧化这一新现象；最后对氮素、pH等水质指标在氨化反应过程中的的转化规律进行了分析，以期为肉类加工废水的生物脱氮处理工艺提供一定的理论指导。

Water quality indexes in the course of ammoniation reaction was analysed to provide theoretical guiding for the biological denitrification of meat processing wastewater .

采用ABR工艺对肉类加工废水进行前期氨化处理，通过试验得到最佳水力停留时间为6～8h，氨氮递增率在90%～196%之间；同时发现了厌氧氨氧化这一新现象；最后对氮素、pH等水质指标在氨化反应过程中的的转化规律进行了分析，以期为肉类加工废水的生物脱氮处理工艺提供一定的理论指导。

The experimental result of anaerobic ammoniation shows, the most appropriate hydraulic retention time is between six and eight hours, the longer the HRT , the higher the rate of NH3-N net increase.

现场调查分析表明，屠宰废水是一类富含有机氮的有机废水，其NH_3-N浓度在整个生物处理工艺过程中存在一定变化规律，特别在厌氧之后，NH3-N浓度将大幅增加(净增加70%—150%)，显然多数以进口NH_3-N指标进行硝化及反硝化的设计是错误的，且是导致NH_3-N难以达标的一个重要原因。
