Efficient water body purifying agent

Abstract

The invention provides an efficient water body purifying agent. The efficient water body purifying agent comprises a carrier and sulfur-oxidizing bacteria loaded in a carrier pore canal, wherein the carrier is of an interconnected through macroporous structure; connected pore windows with 1 to 10 mum are attached to a pore wall; the pore wall is constructed by a mesoporous appearance structure. Aconcentrated water purifying machine has the advantages of large bacteria carrying capacity, high survival rate, large flora advantage, high purifying efficiency, and higher stability and effectiveness.

Description

technical field [0001] The invention belongs to the field of water body purification, and in particular relates to a sulfur-oxidizing bacteria bioactive purifying agent based on a macroporous mesoporous silica carrier, a preparation method thereof, and an application thereof. Background technique [0002] Studies have shown that in today's aquaculture process, due to the low bait utilization rate, excessive discharge of residual bait, and excessive discharge of farmed animal feces, eutrophication of water bodies, C, N, and P enrichment pollution of sediments and sediment oxidation are caused. The reduction potential is lowered. Increased eutrophication of water bodies will lead to excessive ammonia nitrogen and nitrite, which will have a toxic effect on aquatic animals. The discharge of a large amount of aquaculture wastewater has caused a huge impact on the surrounding environment. The water environment has deteriorated, red tides have occurred frequently, and ecological b...

Problems solved by technology

For example, in the cell immobilization technology, the embedding method is to disperse the cells into the porous carrier, or use the polymer to embed the cells inside when the gel is formed, so as to achieve the purpose of fixing the cells, which is currently the most widely used. However, when using the biological metabolic function of sulfur-oxidizing bacteria to treat sulfur-containing wastewater, the metabolic activities of functional microorganisms in the reactor are often inhibited due to the high concentration of sulfide in the influent, resulting in the need for a long time for functional microorganisms. Long adaptation period, and because the adhesion of sulfur oxidizing bacteria is not strong, it is easy to lose with the effluent, so it is not easy to maintain a high concentration of sulfur oxidizing bacteria in the reactor

[0004] Such as CN103951052 A Beijing University of Technology discloses the preparation and application of a polyurethane carrier-based sulfur-oxidizing bacteria immobilized bioactive filler, blocky polyurethane foam is solidified by extruding and absorbing the embedding fluid to absorb and solidify the embedding fluid loaded with sulfur-oxidizing bacteria However, the polyurethane material has the following problems: (1) The density is single, and there are only two states o
