AI Technical Summary

Technical Problem

Existing bioremediation technologies are slow to activate in heavy oil pollution in the intertidal zone and are easily diluted by seawater, resulting in low remediation efficiency and difficulty in effectively dealing with complex heavy oil pollution.

Method used

A solid bioremediation formulation composed of immobilized heavy oil-degrading bacteria, immobilized laccase, nitrogen and phosphorus nutrient slow-release preparation, and rhamnolipid surfactant is used. Modified zeolite is used to enhance microbial adsorption and oxygen mass transfer, provide continuous nutrient support, and enhance the microbial degradation capacity.

Benefits of technology

It enables rapid activation and sustained action of bioremediation agents in the intertidal zone, improves the degradation efficiency of heavy oil pollution, overcomes the problems of dilution and slow activation of traditional agents, and has environmental adaptability and high-efficiency degradation capabilities.

Abstract

The present application is suitable for the field of bioremediation technology, and provides a bioremediation preparation for heavy oil pollution, which comprises an immobilized heavy oil degrading bacterial population preparation, an immobilized laccase preparation, a slow-release nitrogen and phosphorus nutrient preparation, and a rhamnolipid surfactant; the bioremediation preparation is a solid preparation. The present application also provides application of the bioremediation preparation in a heavy oil pollution intertidal zone. The bioremediation preparation has the advantages of not being easy to lose, fast bioremediation starting speed, being superior in competition with indigenous bacterial species, and good environmental tolerance, thereby overcoming the problems of slow starting speed and fast failure speed of traditional bioremediation preparations in remediation of heavy oil pollution intertidal zones.
