AI Technical Summary

Technical Problem

Existing microbial reagents for water pollution control have limited functions and are difficult to cope with complex water pollution. The activity of microorganisms is easily affected by environmental factors, resulting in unstable treatment effects. Chemically enhanced reagents may disrupt the ecological balance and cause secondary pollution.

Method used

The compound microbial preparation is composed of magnetically targeted bacterial-algae symbiosis, sodium carboxymethyl cellulose, biochar nanoparticles, sodium alginate, polyvinyl alcohol, chitosan, trehalose, glycerol and calcium carbonate. Through the pollutant degradation chain composed of bacteria and microalgae, combined with the guidance of an external magnetic field, a self-oxygenated and self-circulating ecosystem is formed.

Benefits of technology

It achieves simultaneous and efficient conversion of pollutants such as ammonia nitrogen, organic matter and total phosphorus in water bodies, improves utilization rate, forms long-term treatment effect, is environmentally friendly and safe, and is suitable for sensitive water areas.

Abstract

The invention relates to the technical field of environmental treatment, in particular to a composite microbial preparation for water pollution treatment and a preparation method thereof. The composite microbial preparation for water pollution control is prepared from the following components in percentage by mass: 22 to 35 percent of magnetic targeting bacteria-algae symbiont, 5 to 6 percent of sodium carboxymethyl cellulose, 3 to 4 percent of charcoal nano powder, 35 to 40 percent of sodium alginate, 10 to 12 percent of polyvinyl alcohol, 2 to 3 percent of chitosan, 5 to 6 percent of trehalose, 3 to 4 percent of glycerol and 2 to 3 percent of calcium carbonate. The algal-bacterial symbiotic system disclosed by the invention has relatively high bacterial colony density, can efficiently degrade various pollutants in a polluted water body, can realize accurate positioning and enrichment treatment, realizes long-acting self-maintenance purification of water pollution treatment by combining with an algal-bacterial mutual benefit micro-ecological system, and is environment-friendly in all components, low in cost and easy to popularize. The risk of secondary pollution is avoided, and the unification of efficient treatment and environmental safety is realized.
