Investigation and evaluation of water environment around domestic waste landfill site——Taking a domestic waste landfill site in Guizhou as an example
In recent years,problems such as groundwater pollution and soil heavy metal exceeding the standard caused by landfill leachate leakage have occurred in many areas,posing a serious threat to local residents living and production water and food security.Taking a domestic waste sanitary landfill site in Guizhou as the research object,the hydrogeological conditions around the landfill site were investigated in detail,and the surface water in the upstream,in-site and downstream of the landfill site was systematically sampled and detected.The water quality pollution index and water quality were evaluated by single factor index method,comprehensive evaluation method and grey correlation analysis method.The results showed that the water quality indexes of some surface water in the downstream area of the landfill were seriously exceeded,and the water pollution degree of some sampling points was heavy pollution.The main material composition of the pollutants in the sample is basically the same as that of the leachate pollutants in the domestic waste sanitary landfill site,indicating that there is leachate leakage in the domestic waste landfill site,which pollutes the downstream surface water.
