农村历史遗留非正规生活垃圾填埋点环境整治案例研究OA

Taking the project of Environmental Remediation of Historical Informal Domestic Waste Landfills in Rural Areas around Baiyangdian Lake as a case,and in combination with the socio-economic development status of Anxin County in Xiong'an New Area,a targeted technical route of in-situ excavation+in-situ treatment+centralized screening+classified disposal+pit-pond restoration was formulated.The formulation was conducted on the premise that no resident disturbance and secondary pollution such as odor diffusion and sewage leakage were caused,and an economical and highly efficient ecological restoration goal was ultimately achieved.In response to the core challenges,including dense building distribution in fishing villages around Baiyangdian Lake,restricted road transportation,and unclear underground pipelines that led to high excavation difficulty.Most sites being adjacent to sensitive water bodies,and some sites close to residential buildings where stringent control of secondary pollution(sewage leakage,odor diffusion and noise nuisance to residents)was required,supporting integrated screening stations were designed.A classified disposal mode was realized accordingly:lightweight waste was transported to domestic waste incineration power plants for treatment,construction waste was recycled for comprehensive resource utilization,and undersize materials were backfilled after their compliance with the standards was verified by testing.This case was systematically analyzed from the dimensions of project difficulty dissection,engineering design optimization and innovation in the implementation process,so as to provide reliable technical references for the implementation of similar projects and the formulation of relevant standards.
