Testing And Analysis Of Water Quality During The Flood Songhua River In Jilin City

Background:Based on the monitoring results of water quality during the flood comparison, system analysis of monitoring results of water quality, understanding of the quality change of water supply, health supervision and management, water supply planning, water resources protection, water intake, water treatment, water purification and disinfection of emergent public health events provide important scientific material. Jilin city urban and rural drinking water status and water supply demand, exploration of drinking water hygiene supervision and the new thinking of development, to improve the drinking water hygiene supervision and management provides a basis and suggestions.Purpose:Through documentation, sample collection and statistical analysis method, the Songhua River coast 20 sampling points during the flood period in 2009 2010 and compare with the results of water quality detection.In accordance with the drinking water standard test method for water collection and preservation requirements, sample collection, transportation and storage.Access to relevant documents, and combining with the actual working conditions, combining the opinions of experts to adjust and modify, in accordance with the drinking water standard examination method in water quality testing.On the collection of basic data and field investigation data and test results by using Epi-data3.02 software to establish database, at the same time by double entry, and the data was strictly review. After finishing checking database, using SPSS 13 statistical software package for analysis.Flood and related indexes, mainly uses the x 2 test. Analysis of the main indicators: pH, ammonia nitrogen, oxygen, turbidity, manganese, iron, chroma, visible to the naked eye, the total number of bacteria, total coliforms, total alpha activity, total beta.Results:By 2010 the flood period of monitoring results of water quality monitoring results of water quality with the same period in 2009 and qualified rate statistical analysis, as long as including sensory traits ( pH, turbidity, chroma and visible ), metal ( Mn, Fe ) index, comprehensive index of organic matter ( ammonia, oxygen consumption ), microbial indicators ( total aerobic bacterial count, coliform flora ), radioactive indicators ( total alpha activity, total beta ). During the flood of 2010 samples collected water quality turbidity qualified rate is 1.94%, the same period of 2009 samples collected turbidity qualified rate is 26.43%; the 2010 floods during the acquisition of water quality chroma qualified rate is 15%, the same period of 2009 samples collected color pass rate of 85%; the 2010 floods during the acquisition of water quality of manganese element in the qualified rate is 59.2%, 2009 simultaneous acquisition of manganese sample pass rate of 90%; the 2010 floods during the water quality monitoring results of elemental iron qualified rate is 7.5%, the same period in 2009 of water quality testing results of elemental iron qualified rate is 74.3%; the 2010 floods during water quality detection, ammonia indicators qualified rate is 65%, the same period in 2009 quality detecting ammonia indicators qualified rate of 90%;in 2010 during the flood water quality detection the results of oxygen consumption indicators qualified rate is 17.2%, the same period in 2009 monitoring results of water quality index of oxygen consumption of the qualified rate is 75%; the 2010 flood monitoring results of water quality index during the colony total qualified rate is 11.1%, the same period in 2009 the total number of colonies index water quality detection qualified rate is 63.6%; the 2010 flood period results in determination of water quality total coliform indicators qualified rate is 15.4%, 2009 the corresponding period water quality detection of total coliforms index 53 pass rate In 2010 6%;during the flood water quality testing results of total alpha activity indicators qualified rate is 41.4%, the same period in 2009 the total alpha radioactivity index water quality detection qualified rate is 69.3%; the 2010 flood period results in determination of water quality total beta indicators qualified rate is 39.4%, the same period in 2009 total beta index water quality detection qualified rate is 67.9%.Conclusions:1.through to the 2010 floods during the Songhua River water quality testing results and the 2009 Songhua River water quality monitoring results of the statistical analysis, we can see the flood on the Songhua River water quality impact;2.Jilin in the flood period of drinking water hygiene supervision and management method is feasible, but due to the lack of experience in this area, during the flood water quality is affected;3. Jilin city in sudden public health events occur, to life drinking water infrastructure and supporting facilities, insufficient investment, public health emergency treatment technology lags behind.
