Abstract

The invention discloses a river sediment biology base degradation composite and application thereof. The composite comprises 10-17 percent by weight of porous carrier, and 73-85 percent by weight of pollutant degrading bacteria and 5-12 percent by weight of synergistic agent which are attached to the surface of the porous carrier. In a river sediment biology base, a porous material is taken as a carrier, the pollutant degrading bacteria and the synergistic agent are attached to the carrier, the pollutant degrading bacteria belong to a dominant bacterial community, have remarkable mutual synbiosis action, are repellent to mixed bacteria simultaneously, and are prevented from being lost by being attached to the surface of the carrier, so that a good anti-pollution effect is achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a bio-based degradation compound for river bottom mud and its application. Background technique [0002] With the increasing development and utilization of environmental resources by human beings, a large amount of sewage containing nitrogen and phosphorus nutrients is discharged into lakes, reservoirs and rivers. At the same time, in order to increase the yield of crops, the amount of chemical fertilizers and livestock manure applied to farmland has increased year by year, and the nutrients entering the water body have continued to increase through the erosion and infiltration of rainwater. The influence of these human factors makes the pollution and eutrophication of lakes and reservoirs more and more serious. According to the 2010 Bulletin on the State of the Environment in China, among the 26 nationally controlled key lakes (reservoirs), 1 lake (reservoir) w...
