The poultry excrement excreta although is one kind of source of pollution, but if it’s reasonably effectively processes, carries on the development use, the use of variable-waste- can become an item important and the availability of resources. Among them, the application microorganism harmless live fungus preparation fermentation technology processing poultry excrement is quite scientific, ideal and the economical practical method, produces the harmless metaplasia organic is fat is one kind of important fertilizer. The poultry excrement year withdrawal according to 1.9 billion t, converted into standard for the chemical N 5.7 million t, 4.2 million t phosphorus standard, the standard K 4.2 million t, converted standard fertilizer together a total of about 13.2 million t, , and may provide the organic matter is 28.5 million t. At the same time, the poultry excrement through biological fermentation after treatment eliminates the eggs, and other harmful bacteria and microbes, enable the environment to be improved and the purification.
