/ A METHOD OF MANUFACTURING EGG SHELL TYPE MEDIA FOR BIOLOGICAL WASTEWATER TREATMENT AND OFFENSIVE ODOR REMOVAL

摘要

Provided is a method for producing a fluidized bed microbial carrier in the form of a hollow ball for wastewater treatment and odor removal, and coating an adhesive and an active support material on a floating body made of foamed plastic particles having a specific gravity of 1.0 g / cm 3 or less, followed by A hollow hollow ball-type fluidized bed microorganism carrier is prepared by curing the adhesive of the floating body coated with the active support material and firing at a temperature at which the foamed plastic is decomposed or reduced in volume.;The manufactured hollow ball-type microbial carrier not only has an excellent removal efficiency of contaminants, but also by adding sawdust or crushed small foamed plastic particles, other pore regulators, etc., when the microbial carrier is manufactured, it makes a gap or pores. Long-term growth of microorganisms in the hollow ball ensures stable removal of contaminants even under fluctuations in flow rate and concentration load of waste water.
