Abstract

The invention belongs to the technical field of biological filter fillers, and particularly relates to a method for preparing a biofilter filler nutritional agent from poultry manure, which comprises the following steps: (1) collecting poultry manure, conducting stirring and mixing, controlling the water content to be 50-55%, uniformly dividing the formed mixture into 5-10 parts by weight; drying and carbonizing biomass auxiliary raw materials, then adding a strain accelerant, uniformly conducting stirring and mixing, then adding 1 equal part of poultry manure, inoculating EM bacteria, uniformly conducting stirring, conducting standing for 48 hours, then adding 1 equivalent of poultry manure every two days until the poultry manure is completely added, and completing fermentation treatment; and (2) adding ammonium sulfate, ferrite, sodium bicarbonate, starch and persulfate into the fermented product, and uniformly conducting stirring and mixing to obtain the filler nutritional agent for a biological filter. The nutritional agent provided by the invention promotes adsorption, stationing and propagation of bacteria and microorganisms on the filler of the biological filter, so that the formation rate of a biological membrane is promoted, and biological treatment of sewage is realized at a relatively high speed.

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.

Examples

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...
