| Zhongyuan oilfield base sewage treatment plant existing wastewater treatment process of operation parameters, is mainly by activated sludge integrated oxidation ditch treated with method of COD value and water BOD value to adjust sewage treatment facilities, but because the running parameters determination BOD value at least 5 days to a result, determination of COD value at least four hours to get out the results, the combination of monitoring time is too long, can't reflect the real situation of wastewater, the direct consequence is that wastewater treatment effect is poor, cannot guarantee sewage 100% standards.TOC represents all organic matter content in water, from 19 1930s up as in water determination of organic matter index, from the developing situation at home and abroad to see, TOC analysis in water quality monitoring is widely application domain, analysis, the content of TOC has become many countries of the world water treatment and quality control of the main means.This paper on 2009 zhongyuan oilfield base sewage treatment plants 1 to December sewage import and export watery TOC, COD analysis and test, established the zhongyuan oilfield base wastewater treatment plant TOC-COD quantitative relationship between the model, and the model test. Based on this, probes into with accurate, fast and clean TOC test to replace much error, experimental process trival, easy generation secondary pollution COD test technical feasibility, and attempts to reveal the COD and TOC leading indicator relation, the internal cause for sewage real-time standards provide data support. |
