Investigation And Countermeasure Analysis Of Main Pollutants In Water Quality Of Luoyang River Basin

Research backgroundsThe 13 th five-year plan for the comprehensive management and construction of water environment in key river basins calls for effectively increasing and improving the supply of basic public services,improving the quality of water environment in key river basins,restoring water ecology and ensuring water security.The small watershed of fujian province and rural water environment improvement plan(2016-2020),at the same time put forward in 2020,90% of small watershed to achieve class above water.In recent years,the upstream reservoir construction in ?the luoyang river basin,the industrial enterprises in the industrial areas around the luojiang river basin have increased sharply,and the agriculture and breeding industry are also in a period of rapid growth.Therefore,strengthening the environmental protection of the luoyang river basin is of great significance to the sustainable development of the luojiang region.Research purposesThe main pollution factors in the luoyang river basin were investigated,and the prevention and control measures were explored.Research methodsThe water quality monitoring reports of the luoyang estuary section of the luoyang river basin in the past five years were investigated to determine the main pollution factors.11 months of the main pollution factor is made of continuous monitoring,3 times a day,in 11 months respectively at 9:00 in the morning,at noon and night 17:30pm on each sampling section water sampling,monitoring data and through correlation analysis,variance analysis(including single factor analysis,three factors analysis,four factor analysis)and statistical analysis of regression analysis indicates that the factors affecting the main pollution factor.Based on the investigation and analysis of the pollution sources around the river basin,it is found that the pollution of the river basin restricts the sustainable economic development of luojiang region,restricts the development of related industries in the river basin,and damages the sustainable utilization of the river basin resources and the ecological environment of the river basin.Research resultsIn the background of water quality monitoring in the past five years,the main pollution factors of the luoyang river basin were fecal e.coli and chlorophyll a.For fecal escherichia coli and chlorophyll a design monitoring cross section,and continuous monitoring of pollution factors for 11 months inductive analysis and statistics of the monitoring data obtained fecal escherichia coli in 25 ?optimum growth,its content and sampling point correlation is the largest,with the temperature,humidity,weather,month,little correlation between the sampling times,fecal escherichia coli concentration said big basin surrounding population or farms;Chlorophyll a is most suitable for growth at 29?,and has the greatest correlation with temperature.It has a general correlation with humidity,weather,sampling time and month,but little correlation with sampling point.A large concentration of chlorophyll a means that there are many algae in the water and the water quality is poor.The main pollution sources in luoyang river basin are rural domestic sewage and aquaculture.ConclusionThis paper provides some reference Suggestions for the improvement of luoyang river basin and provides a new way of thinking for the further development of luojiang district based on luoyang river basin.
