Embodiment 1
[0017] A kind of sludge treatment process that the embodiment of the present invention proposes, comprises:
[0018] First build a circulating sludge flow channel, and lay a biological bed composed of algae and spores on the flow channel, dilute the sludge to be treated with water into a flowable state, and then introduce it into the sludge flow channel, allowing the sludge to flow The channel circulates for 2 hours, using the algae and spores on the biological bed to absorb heavy metals in the sludge and reduce the content of heavy metals in the sludge; then, add DM to the sludge at a rate of 300 grams per ton of sludge Activator, and stir the sludge during the addition process to ensure that the DM activator is evenly mixed with the sludge. After the DM activator is added, the sludge is dehydrated so that the water content of the sludge is in the range of 50%-55%. ;Concentrate the dehydrated sludge into the fermentation tank for 7 days of fermentation, and start heating when...
Embodiment 2
[0020] A kind of sludge treatment process that the embodiment of the present invention proposes, comprises:
[0021] First build a circulating sludge flow channel, and lay a biological bed composed of algae and spores on the flow channel, dilute the sludge to be treated with water into a flowable state, and then introduce it into the sludge flow channel, allowing the sludge to flow The channel circulates for 4 hours, using the algae and spores on the biological bed to absorb heavy metals in the sludge and reduce the content of heavy metals in the sludge; then, add DM to the sludge at a rate of 375 grams per ton of sludge Activator, and stir the sludge during the addition process to ensure that the DM activator and the sludge are evenly mixed. After the DM activator is added, the sludge is dehydrated so that the water content of the sludge is in the range of 55%-65%. ;Secondly, concentrate the dehydrated sludge into the fermentation tank for fermentation for 7 days, and start h...
Embodiment 3
[0023] A kind of sludge treatment process that the embodiment of the present invention proposes, comprises:
[0024] First build a circulating sludge flow channel, and lay a biological bed composed of algae and spores on the flow channel, dilute the sludge to be treated with water into a flowable state, and then introduce it into the sludge flow channel, allowing the sludge to flow The channel circulates for 5 hours, and the algae and spores on the biological bed are used to absorb heavy metals in the sludge to reduce the content of heavy metals in the sludge; then, add DM to the sludge at a rate of 450 grams per ton of sludge Activator, and stir the sludge during the addition process to ensure that the DM activator is evenly mixed with the sludge. After the DM activator is added, the sludge is dehydrated so that the water content of the sludge is in the range of 65%-70%. ;Secondly, concentrate the dehydrated sludge into the fermentation tank for 8 days of fermentation, and st...
