Abstract
Description
A device for using microorganisms to transform the bottom mud of aquaculture ponds to reduce the organic carbon content Technical Field
[0001] The utility model belongs to the technical field of sludge treatment, and more specifically relates to a device for using microorganisms to transform the bottom mud of aquaculture ponds to reduce the organic carbon content. Background Technique
[0002] Organic carbon mainly comes from residual baits, excrements, animal and plant residues, etc. High concentrations of organic carbon will cause microorganisms to decompose and consume a large amount of oxygen, resulting in hypoxia at the bottom, and then generating harmful substances such as hydrogen sulfide and methane, which are harmful to aquaculture organisms. At this time, it is necessary to clean out the sludge at the bottom of the pond. The extracted sludge still contains a high concentration of organic carbon. Direct discharge or landfill will cause secondary pollution, and resource utilization requires reducing the organic carbon content. In the prior art, usually, the sludge and strains are mixed in a treatment tank and then left to stand for sedimentation. During the standing process, it is difficult for oxygen to mix with the sludge and strains, thus affecting the treatment efficiency. Secondly, the treated sludge still needs to be dehydrated and then pressed into cakes, with low production efficiency. We propose a device for using microorganisms to transform the bottom mud of aquaculture ponds to reduce the organic carbon content. Summary of the Invention
