Chicken manure/corn straw composite co-pyrolysis activated carbon soil remediation agent, preparation method thereof and application of remediation agent

The invention discloses a chicken manure/corn straw composite co-pyrolysis activated carbon soil remediation agent, a preparation method thereof and an application of the remediation agent. The methodincludes the steps: (1) drying chicken manure and corn straws, crushing the dried chicken manure and the dried corn straws, and screening the crushed chicken manure and the crushed corn straws to obtain chicken manure powder and corn straw powder; (2) uniformly mixing the chicken manure powder and the corn straw powder, adding binding agents, uniformly heating and stirring mixture, and granulating and drying the mixture to obtain composite spherical particles; (3) heating the composite spherical particles to reach the temperature of 400-600 DEG C to carbonize the particles for 1-2 hours, heating the particles to reach the temperature of 750-850 DEG C, leading in water vapor to activate the particles for 20-40 minutes, and cooling the particles to reach room temperature to obtain the chicken manure/corn straw comp
