Two set of DAF sewage disposal equipment of U.S.A were introduced into Jinzhou mechanical work section in1999, which were used to treated containing oil sewage. 1999年锦州机务段引进美国DAF污水处理器二台,用于机务段检修,清洗机车的含油污水处理。
Moreover, special electric power supply loops, reconstruction of ditches, and a sewage treatment work with daily disposal capacity of80 thousand tons and its pipeline shaft have been completed too. 另外,还完成了供电专线建设、沟渠改造和日处理能力8万吨的污水处理厂及管线改造工程。
Subsurface wastewater infiltration system ( SWIS) is a sewage purification technique combined manual work with sel-purification. 土壤地下渗透系统,是一种自然生态净化与人工工艺相结合的污水净化技术。
This method can also be used to other designs of water supply and sewage work. 此方法也可以推广至给排水工程其他系统的设计。
This paper is about treatment leachate after recycling irrigation by chemical, Achieving standard of sewage recovery, the recovered sewage is able to work on landfill green. 运用化学方法对渗滤液回灌后的残液进行处理,以达到污水回用的标准,出水可供垃圾填埋场作为绿化用水。
Fuzzy Decision-making of the Sewage Disposal Extension Work 污水处理扩建工程的模糊决策
The forecasting of water quality variation is very important in the process of sewage treatment, which helps the control system work reliably and steadily. 在污水处理系统过程控制中,对水质变化规律进行预测是控制系统可靠、稳定运行的重要环节。
Therefore, strengthens the city life sewage takes the second water source sales commission aspect the research work appears extremely urgently. 因此,加强城市生活污水作为第二水源回用方面的研究工作显得极为迫切。
This innovation can improve hear transfer results, reduce sewage dischage and air pollution and lower maintenance work. 应用结果增强了传热效果、减少了污水排放和大气污染,降低了检修劳动负荷。
The results of the numerical model of COD distribution is also introduced. Finally, the summary value of the engineering benefit of the sewage drain work and the effect of the sewage dilution are made. 文中还对COD分布的数学模型成果作了扼要介绍,文末,综合评价了入江排污工程效益和污水释放效果。
The case of the successful operation of the sewage system, proved the potential of mining work the necessity, proposed the similar factories through reduction, control of wastewater emissions, the sewage system operation cost and other issues will be solved. 该案例的成功运行,证明了污水系统潜力挖掘的工作的必要性,建议各类似工厂通过减排,控制污水排放总量,随之而来的污水系统运行费用等问题都将得到很好的解决。
In sewage treatment plants, as the poor environment, some work is not suitable for long time working for people. Therefore, the demands of automation operations are put forward. 而在污水处理厂,由于环境恶劣,某些工作不适合人工长期工作,这就对污水处理厂的自动化作业提出了很高的要求。
Therefore, if the sewage network cannot work normally, sewage treatment plant will become energy dissipation and low pollutant reduction, and will bring serious harm to river environment. 因此,倘若污水管网未能正常运行,那么污水处理厂就变得耗能而减排量低,对社会、环境带来严重的危害。
