Abstract

The invention discloses a method for culturing a biological film on biological stuffing and belongs to the technical field of biological film culture. According to the method disclosed by the invention, trace gibberellin and fulvic acid are utilized as excellent nutritional ingredients to achieve effects of promoting microorganism growth, promoting cell absorption, relieving wastewater pollution and remediating a water body biological system; trace metal elements are necessary for microorganism growth; furthermore, some metal elements are constituent parts of biological enzyme, can stimulate enzyme production performance of active bacteria and can improve wastewater treatment efficiency. The method disclosed by the invention solves the problems that existing biological film formation speedis slow and a wastewater treatment effect is poor.

Description

technical field [0001] The invention belongs to the technical field of biofilm cultivation, and in particular relates to a method for cultivating biofilms on biological fillers. Background technique [0002] The increasingly serious environmental pollution is threatening the water sources and water bodies that human beings rely on for survival. In the face of the current situation of my country's water resources, the country has introduced more practical measures and regulations related to pollution control and emission reduction, and the restoration of polluted or facing polluted water resources is even more important. At present, when biofilm reactors are used to treat wastewater, because the wastewater may contain high salinity and various harmful substances, they not only accumulate in large quantities in the biofilm microorganisms on the filler, but also adhere to the surface of the filler in the form of microcrystals. , so that the biofilm is firmly attached to the su...
