Embodiment 1
[0013] Fully mix 500kg of sludge and 50kg of straw through a mixer, and add 5kg of compound strain BYM expansion bacteria during the mixing process. The sludge used in this example is from the sludge of urban domestic sewage treatment plant, and its moisture content is about 80%. The straw is crushed wheat straw, and the length of the crushed straw is between 5mm and 20mm. After the materials are fully mixed, they appear as lumps.
[0014] After fully mixing 1000kg of polluted soil with the above materials, ferment. During the fermentation process, it is necessary to ensure that the oxygen content in the soil air remains above 10% (volume ratio); in addition, an appropriate amount of water is sprayed on the pile every day to maintain the moisture content of the mixed material between 35% and 60%.
[0015] After 7 days of fermentation, soil samples from different parts of the pile were taken to detect the content of hexavalent chromium, and it was found that the content of hex...
Embodiment 2
[0017] Fully mix 300kg of sludge and 30kg of straw through a mixer, and add 5kg of compound strain BYM expansion bacteria during the mixing process. The sludge used in this example is from the sludge of urban domestic sewage treatment plant, and its moisture content is about 80%. The straw is crushed wheat straw, and the length of the crushed straw is between 5mm and 20mm. After the materials are fully mixed, they appear as lumps.
[0018] After fully mixing 888kg of polluted soil with the above materials, fermentation is carried out. During the fermentation process, it is necessary to ensure that the oxygen content in the soil air remains above 10% (volume ratio); in addition, an appropriate amount of water is sprayed on the pile every day to maintain the moisture content of the mixed material between 35% and 60%.
[0019] After 7 days of fermentation, soil samples from different parts of the pile were taken to detect the content of hexavalent chromium, and it was found that...
Embodiment 3
[0021] Fully mix 400kg of sludge and 50kg of straw through a mixer, and add 4kg of compound strain BYM expansion bacteria during the mixing process. The sludge used in this example is from the sludge of urban domestic sewage treatment plant, and its moisture content is about 80%. The straw is crushed wheat straw, and the length of the crushed straw is between 5mm and 20mm. After the materials are fully mixed, they appear as lumps.
[0022] After fully mixing 950kg of polluted soil with the above materials, ferment. During the fermentation process, it is necessary to ensure that the oxygen content in the soil air remains above 10% (volume ratio); in addition, an appropriate amount of water is sprayed on the pile every day to maintain the moisture content of the mixed material between 35% and 60%.
[0023] After 7 days of fermentation, soil samples from different parts of the pile were taken to detect the content of hexavalent chromium, and it was found that the content of hexa...
