Abstract
Description
technical field
[0001] The invention belongs to the technical field of biofilter fillers, in particular to a method for preparing nutrient for biological filter fillers by using poultry manure. Background technique
[0002] Biological filter is a kind of sewage treatment technology, which uses granular filler and its attached biofilm as the main treatment medium, fully exerts biological metabolism, biological filtration, physical adsorption of biofilm and filler particles, integrates biological oxidation process and solid Liquid separation in one, so that the removal of BOD, COD, SS filtration and nitrification process can be completed in the same unit reactor, and if anaerobic zone is added in the biological aerated filter, denitrification and denitrification can also be carried out at the same time and phosphorus removal. As the core component of the biological aerated filter, the filler has a direct impact on the efficiency of the biological aerated filter.

Embodiment 1
[0034] A kind of method utilizing poultry manure to prepare biological filter filler nutrient, comprises the following steps:
[0035] (1) Collect poultry manure, stir and mix, control the moisture content to 50%, and then divide it into 10 parts by weight; dry and carbonize the auxiliary raw materials of biomass, then add the bacteria promoter, stir and mix evenly, and then add 1 Inoculate an equal portion of poultry manure with EM bacteria, stir evenly, let stand for 48 hours, then add 1 equal portion of poultry manure every two days until all are added, and the fermentation process is completed. During the entire fermentation process, the temperature of the material is kept at 45 ℃;
[0036] Wherein, the biomass auxiliary raw material is straw powder;
[0037] The strain accelerator is formed by mixing potassium dihydrogen phosphate, urea, brown sugar and water in a weight ratio of 0.08:0.12:0.3:1;
[0038] Described EM bacterium is that lactic acid bacterium, bacillus, s...
