Abstract

The invention discloses a biological dehydration method for garbage, which comprises piling garbage on a site, covering a molecular screening film on the garbage pile, and carrying out forced ventilation on the garbage pile until the dehydration is finished. The molecular screening film at least comprises an expanded teflon film layer, wherein the thickness of the expanded teflon film is 0.22-0.26 mu m, the micropore size is 0.5-1 mu m, and the number of pores is 10-20 billion / cm<2>. The molecular screening film is covered to biologically dehydrate the biochemical garbage, thereby effectively preventing malodorous gas in the pile from escape, ensuring that water can smoothly pass through the molecular screening film, quickly dehydrating the garbage pile and implementing a pollution-free processing environment.

Description

technical field

[0001] The invention relates to the technical field of garbage treatment, in particular to a biological drying method of garbage. Background technique

[0002] High moisture content, high content of kitchen waste organic matter, and low calorific value are the basic characteristics of urban waste in my country. If this kind of mixed waste with high water content is used for landfill, it will produce a large amount of leachate and greenhouse gas; if it is used for incineration, it will reduce the low calorific value of the waste, resulting in a decrease in the efficiency of incineration heat energy; in addition, the high water content will also make The different components of waste stick to each other, and the mechanical sorting effect is poor, which limits the possibility of optimizing the waste treatment process through sorting. Therefore, under the premise that it is difficult to fully carry out garbage sorting and collection, it is urgent to develop tech...
