Description

Technical field

[0001] The present invention involves an organic fertilizer, especially the use of chicken manure to make refined water -soluble organic fertilizers. Background technique

[0002] At present, with the rapid development of the poultry and livestock industry and the expansion of the breeding scale, more and more feces produced by poultry and livestock are increasingly prominent to the problems caused by the environment.According to data from the National Bureau of Statistics, in 2014, Chinese livestock and poultry manure emissions were more than 3 billion tons, which was 1.6 times that of the total industrial solid waste emissions during the same period.The proportion of the total amount of oxygen, ammonia nitrogen, and total phosphorus emissions of livestock and poultry breeding accounted for 95%, 78%, and 74%of the total emissions of agricultural sources.EssenceAmong them, chemical oxygen demand (COD) emissions are 3.23 times the amount of industrial sources and 1...
