Abstract

The invention belongs to the technical field of biological water purifiers, in particular to a microbial water purifier with light-enzyme composite catalytic function cultivated in aquaculture anaerobic sewage. The water purifying agent is prepared by placing porous carbon-iron oxide material powder in a culture medium prepared from aquaculture anaerobic sewage, then inoculating the compound strain into the culture medium, co-cultivating with shaking and drying. Since the carbon surface in the porous carbon-iron oxide material contains hydrophilic functional groups and the iron oxide has obvious magnetic properties, the composite material exhibits good water dispersibility and magnetic separation function. The organic matter adsorbed on the carrier can be efficiently utilized by microorganisms as a nutrient substrate, and at the same time be catalyzed and degraded by carbon ferrite photocatalyst and microbial enzymes. Therefore, the water purifier has multiple purification functions of adsorption and photo-enzyme composite catalytic degradation. Hydrophilic and magnetically separable, it is very suitable for large-scale treatment of aquaculture anaerobic sewage.

Description

technical field [0001] The invention belongs to the technical field of microbial water purifiers, and in particular relates to a microbial water purifier with light-enzyme composite catalytic function cultivated in aquaculture anaerobic sewage. [0002] technical background [0003] Since the "Thirteenth Five-Year Plan", centering on the development concepts of "stabilizing growth, ensuring safety, and promoting ecology", relevant measures have been taken in livestock and poultry standardization construction, scientific and technological innovation promotion, and ecological breeding, and have achieved certain results. However, my country's livestock and poultry breeding industry still has a large amount of waste and a low level of comprehensive utilization. In some areas, the total amount of livestock and poultry breeding exceeds the environmental carrying capacity, and the regional ecological environment is seriously threatened. There are nitrogenous and phosphorus-containin...
