【摘要】：鄂尔多斯市经历了一个经济迅猛发展的时期。随着经济的发展,缺水对鄂尔多斯市发展的限制越发突显出来。污水处理与中水回用是解决水资源匮乏的一项重要措施,而水质监测是评价污水处理效果的一个重要手段。鄂尔多斯在“十一五”期间建设投运了许多污水处理厂,主要的污水处理工艺以活性污泥、氧化沟法等为主。“十二五”以来,国家在自动监测方面提出在原有二氧化硫和COD实施自动监测的基础上,增加了氮氧化物和氨氮的在线监测。本文是基于鄂尔多斯市污水处理厂在线监测数据,对污水处理工艺在水污染物去除率上的比较。本文包括水污染源自动监控系统的构成、分析仪设备、基本原理等情况。在鄂尔多斯市污水处理厂自动监测数据的基础上研究得出：1.采用对比实验(实验室手工监测与自动在线监测)方法,运用数理统计的方法对实验结果进行相关性分析。通过相关系数的计算,可以得出结论：水污染源自动监测设备监测所得的数据真实可靠,可用于污染物去除率的研究。2.通过调取在线监测系统日数据曲线和月报表,分析得出鄂尔多斯市污水处理厂所收集的污水多为城镇生活污水,进水量较小,时间上来看水质波动性较大,水污染物浓度变化并不规律。3.通过在线监测数据计算得出污染物去除率,单独从污染物去除率的角度考虑污水处理工艺的选择,在市政生活污水的处理中,氧化沟法最佳,其次为活性污泥法,而A2/O(或A/O)脱氮除磷工艺相比较差。
[Abstract]:Ordos city has experienced a period of rapid economic development. With the development of economy, the restriction of water shortage on the development of Ordos city has become more and more prominent. Sewage treatment and reclaimed water reuse is an important measure to solve the shortage of water resources. The monitoring of water quality is an important means to evaluate the effect of sewage treatment. During the Eleventh Five-Year Plan period, Ordos built and transported many sewage treatment plants. The main sewage treatment processes are activated sludge, oxidation ditch process and so on. In the aspect of automatic monitoring, it is proposed that the on-line monitoring of nitrogen oxides and ammonia nitrogen should be added on the basis of the original sulfur dioxide and COD. This paper is based on the on-line monitoring data of the sewage treatment plant in Ordos. The comparison of wastewater treatment process in the removal rate of water pollutants. This paper includes the composition of water pollution source automatic monitoring system, analyzer equipment, On the basis of the automatic monitoring data of Ordos sewage treatment plant, we get the conclusion that: 1. Using the method of contrast experiment (manual monitoring and automatic on-line monitoring in laboratory), Through the calculation of the correlation coefficient, we can draw the conclusion that the monitoring data of the automatic monitoring equipment for water pollution source is true and reliable. 2. Through the daily data curve and monthly report of on-line monitoring system, it is concluded that the sewage collected by the sewage treatment plant in Ordos city is mostly urban domestic sewage, and the amount of influent water is relatively small. In time, the water quality fluctuates greatly, and the concentration of water pollutants varies irregularly .3. the removal rate of pollutants is calculated by on-line monitoring data, and the selection of wastewater treatment process is considered separately from the point of view of removal rate of pollutants. In municipal sewage treatment, oxidation ditch process is the best, followed by activated sludge process, while A 2 / O (or A / O) nitrogen and phosphorus removal process is relatively poor.
