Abstract


Garbage is a hidden resources and wealth. There are enormous energy and value deposited in the garbage. The decreasing、harmless and recycling of garbage composting is a great environmental protection problem which is researching and resolving by many countries all over the world .At present, there are three main harmless ways such as sanitation filling 、 burning and composting in world and out. The composting takes advantage of bio-technology to deal with garbage , it has small investment、running lowly、 saving energy sources、 no repeating pollution and so on. The Garbage composting will be produced to be the organic fertilizer. So the composting will be one of the mainly developing directions in garbage composting. Traditional composting is bio-chemical process of natural microorganism activity, it depends on the soil microorganism in the fertilizer raw material to decline to resolve the organic matter. Because of the total number of soil microorganism in the fertilizer limit, they need some time to breed to carry on ferment. So there are some problems such as long fermenting-cycle、producing-foul smell and poor fertilizer in the traditional composting. If complex microbial community is used in the tradition composting, the problems all above will be resolved. Many researches show that the fertilizer joined in the valid microorganism germ can consumedly promote the progress for ferment, be advantageous to the creation of the high-quality fertilizer. Therefore, complex microbial community manufacture and its application study in the garbage fertilizer have the important and actual application value.Although some researchers in world and out have had some research achievements in composting, most microbes which are gotten in achievements belong to one fungus. There is litter study and research in complex microbial community. Single microbe that has high activity isn’t as good affection as the complex microbial community in composting. In addition, the cellulose decomposition germ, the fruit gum decomposition germ and proteins to resolve the germ are added in the fertilizer ferment process, they can shorten to ferment time effectively and improve the quantity of fertilizer. But because the reasons
