Abstract

The invention discloses a biostimulation bottom mud repairing agent and a preparation method thereof. The bottom mud repairing agent comprises rare earth elements, a stabilizer, a nutrition co-substrate, a slow-release cosolvent and trace elements; the preparation method comprises the steps of material preparation, heating, curing, drying, sieving and mixing. According to the bottom mud repairing agent provided by the invention, the conversion rate of macromolecular organic matters and refractory organic pollutants in bottom mud and the degradation rate of micromolecular organic matters are increased, and the conversion and utilization of nitrogen and phosphorus substances by microorganisms are accelerated; secondly, various microbial enzymes are activated, the enzyme activity is improved, the enzymatic reaction rate is accelerated, and the degradation capacity of indigenous microorganisms on bottom mud pollutants is further enhanced; finally, by using rare earth elements, colloidal substances in the water body can be deposited and attached to the bottom to form an attached biological membrane, the purification capacity is comprehensively improved, and finally the self-purification capacity of the water body is recovered. The preparation method of the biostimulation bottom mud repairing agent provided by the invention is simple to operate, convenient to prepare, low in cost and suitable for industrial large-scale production.

Description

technical field [0001] The invention relates to the field of surface water treatment, in particular to a biostimulating sediment restoration agent and a preparation method thereof. Background technique [0002] Water body sediment (sediment) pollution is an important environmental problem worldwide. The pollutants mainly enter the water body through atmospheric deposition, wastewater discharge, soil erosion, rainwater leaching and scouring, and finally deposit in the bottom mud and gradually enrich it, causing the bottom mud to be seriously polluted. Once the water environment of rivers, lakes and reservoirs changes, the nitrogen and phosphorus nutrients, heavy metals and refractory organic matter deposited in the sediment will be re-released into the water body, affecting the water quality of the overlying water body and forming secondary pollution. The main living places and food sources of living organisms. Pollutants can directly or indirectly cause toxic and harmful ef...
