Method for fixing chlorobenzene volatile organic pollutants by straw biomass charcoal

InactiveCN103056156AReduce environmental risksImproved soilContaminated soil reclamationBiomassPollutant
A method for fixing chlorobenzene volatile organic pollutants by straw biomass charcoal comprises the following steps: shearing straws into fragmentations, drying the fragmentations at the temperature of 80 DEG C, then, transferring the fragmentations to a retort for charing, wherein the initial retort temperature is 200 DEG C, and the retort temperature is increased to 30 DEG C and then to 500 DEG C through temperature programming, lasting for 1.5 hours, naturally cooling and then grinding the fragmentations, screening the fragmentations by a 0.25 mm sieve to obtain biomass charcoal; and enabling the the biomass charcoal to be uniformly mixed with chlorobenzene polluted soil at a ratio of 0.1 to 2 percent of the dry weight of the soil, standing for 4 to 12 weeks, and finishing the fixation. The straws are wheat straws. After biomass charcoal is added in the soil, the volatilization loss of chlorobenzene only accounts for 4.49 to 15.58 percent of that of chlorobenzen when no biomass charcoal is added in the soil, and the bio-concentration of earthworms to chlorobenzene in the soil only accounts for 2.83 to 3.78 percent of that of earthworms to chlorobenzene when no biomass charcoal is added in the soil, so that the environment risk of the volatile pollutants is reduced remarkably. The crop straws resource is rich, is cheap and easily obtained, and the method opens up a novel way for using the straws to restore the polluted soil.

Preparation method of biogas residue organic fertilizer employing biochar as carrier

The invention discloses a preparation method of biogas residue organic fertilizer employing biochar as a carrier. The preparation method includes following steps: performing a solid-liquid separating process to a biogas residue, mixing the biogas residue with minced straw, stirring the biogas residue and the straw uniformly, adding plant ash or calcium oxide to carry out a secondary fermenting process to obtain a fermented product of the biogas residue, mixing the fermented product of the biogas residue with biochar, adding a binding agent, and performing a granulating and dring process to obtain biogas residue-biochar organic fertilizer. The biogas residue organic fertilizer, without addition of any chemical fertilizer, is a pure organic fertilizer. By means of the biogas residue organic fertilizer, yield and quality of crops can be increased and a negative influence of the fertilizer to environment can be reduced. In addition, the biogas residue organic fertilizer is beneficial to improvement of soil and continuous utilization of land. The biochar is prepared by employing water hyacinth and is used as the carrier of the fertilizer so that a problem of application of the water hyacinth can be solved. By means of the straw as an auxiliary material for fermentation, a large amount of agricultural wastes can be digested. Furthermore, on the basis that the biochar has a carbon-sequestration effect, greenhouse gas emission can be reduced. Development and utilization of the biogas residue organic fertilizer are beneficial to alleviation of greenhouse effect.
