陈腐垃圾筛分工艺及其方法

Screening Process and Methods of Stale Waste

在二十世纪九十年代以前,简易垃圾填埋场是我国一直采用的垃圾处理方式,在全国各地形成了大量的陈腐垃圾,其主要特征是配备环保设施不齐全,不完善,其渗滤液等对环境危害较大。其中一小部分可以通过原位治理的方法使其不危害环境,另外一大部分需要通过筛分搬迁无害化处理。它主要阐述需要搬迁处理的陈腐垃圾处理工艺及其方法,通过筛分,陈腐垃圾分成四大类,RDF、腐殖土、废铁和无机骨料。主要通过筛分、磁选、风选和打包的方法进行处理。它包括陈腐垃圾的筛分前处理和筛分处理。

Before the 1990s,the simple landfill is a garbage treatment method that has been adopted in our country all the time,and a large number of stale garbage has been formed in all parts of the country characteristics are that the environmental protection facilities are not complete and perfect,and its leachate is harmful to the environment.A small part of it can be treated in situ so that it does not harm the environment,and a large part needs to be treated innocuously through sieving and relocation,and it mainly describes the process and method of waste disposal that needs to be relocated.Through screening,the waste is divided into four categories,RDF,humus,waste iron and inorganic aggregate.Mainly through screening,magnetic separation,wind separation and packaging methods to deal with.It includes screening pretreatment and screening treatment of stale waste.
