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.
