AI Technical Summary
Existing technologies for treating heavy metal-polluted water bodies are costly and ineffective, and simply using aquatic plants for remediation is generally not very effective.
Aquatic plant intercropping method is adopted, which combines microbial agents and biological growth promoters. Floating-leaved plants and submerged plants are planted in different areas of the river channel, and microbial agents such as EM bacteria, Bacillus subtilis, Bacillus cereus, Rhodopseudomonas spheroidae, and Actinomycetes are used in combination with biological growth promoters to promote plant growth and the absorption and transformation of heavy metals.
It improved the remediation effect of heavy metal pollution, enhanced the purification capacity of aquatic plants, improved river water quality, reduced the concentration of harmful substances, and enhanced the self-purification capacity of water bodies.
