预均化堆放沼气干法发酵在大型垃圾堆放场的应用简介

Introduction to Garbage Biogas Dry Fermentation Stacked with Pre-homogenization on Large Garbage Yards

采用预均化堆放垃圾沼气干法发酵是对城市垃圾和农业废弃物进行快速处理的有效办法。在对大量有机废弃物堆放之初,先把原料的pH值,C/N,温度等因素做初步调节、控制,然后再进行预均化堆放,采用保温复膜厌氧技术快速处理大量有机废弃物快速高效发酵产气。沼气经过简单的提纯处理可以并入城市燃气管网、或用来发电。远离燃气管网的地方沼气液化亦能让从业者获得可观的经济效益。

The biogas dry fermentation staoked with Pre-homogenized garbage is a way of rapid processing large amount of city and rural waste.The factors as pH,C/N,humidity,and temperature,etc,should preliminarily regulated before garbage stacking in a certain way and covered with film.In this way,dry anaerobic fermentation could be processed more quickly in the pile,and biogas was produced and large amount of waste could be treated more fast.The produced biogas can be merged into the city gas pipeline,or used for power generation.
