摘 要:非正规垃圾堆放点整治是推进生态文明建设的必然之举。结合工程案例,对开挖、筛分利用的非正规垃圾堆放点整治方式进行探讨。筛分过程非常复杂,筛分质量会受到筛分物自身特性、筛分设备等因素的影响。通过现场试验,主要探析自然晾晒与添加不同比例生石灰对垃圾土含水率的影响,以及最优含水率下滚筒筛转速对垃圾土筛分质量的影响。结果表明:在生石灰投加量为4%和垃圾土翻抛晾晒1 h、闷盖2 h的条件下,可有效改善垃圾土含水率(24.2%);滚筒筛转速为25 r/min时,得到最优筛分效率(87%),满足工程实施要求。The regulation of informal waste dumps is an inevitable move to promote the construction of ecological civilization.Combining with the project case,the regulation methods of the informal landfill sites through excavation and screening were discussed.The screening process is very complex,and the screening quality would be affected by the screening material characteristics,the screening equipment and other factors.Through the field test,the effect of natural drying and adding different proportion of quicklime on moisture content,and the effect of roller screen speed on screening quality under the optimal moisture content were analyzed.The results indicated that the moisture content of refuse soil could be improved effectively(24.2%)with the addition of 4%quicklime,the refuse soil was overturned and exposed to sunlight for 1 hour followed by covering for 2 hours.When the rotary speed of the drum sieve reached 25 r/min,the optimal screening efficiency(87%)was obtained,which met the requirements for project implementation.
