[embodiment]
A kind of sludge fermentation device of removing heavy metal ion, it comprises tank body 1, tank body 1 can be a cylindrical shape, tank body 1 bottom is provided with into mud pipe 2, tank body 1 top is provided with sludge out pipe 3, is provided with multi-layer helical rotating channel 5 in the described tank body 1, and the middle part of every helical layer rotating channel 5 is provided with sludge pipe 6, the outlet 51 of every helical layer rotating channel 5 communicates with center sludge pipe 6, and the sludge pipe outlet 61 of sludge pipe 6 communicates with the periphery inlet 52 of the spiral rotating channel 5 of last layer.This device is provided with multi-layer helical rotating channel 5, and every layer is spiral shell shape structure, the flow direction of mud be earlier by the outer ring of spiral shell equably each inner ring flow, flow to last layer in the center, again by the center along spiral shell to flowing to outmost turns, flow to last layer by outermost.And so forth, the top that always flow to jar, overflow and going out.
Be provided with inlet pipe 7 in every helical layer rotating channel 5, inlet pipe 7 is provided with a plurality of micro porous aeration heads 71, and the other end limit of inlet pipe 7 is connected with gas-liquid separator 72, and the bottom of gas-liquid separator 72 is connected to into mud pipe 2 by managing 74.The middle part of gas-liquid separator 72 is connected to escape pipe 73.
Also be provided with escape pipe 8 on the tank body 1, the other end of escape pipe 8 extend in the water-sealed tank 4, also is provided with tap water water inlet pipe 41 on the water-sealed tank 4, and tap water water inlet pipe 41 is provided with float valve 42.
The top of sludge pipe 6 is provided with collection chamber 9.As shown in Figure 1, enclose in the collection chamber 9 and be higher than the periphery, the gas accumulation that makes every layer is to the top of collection chamber 9, and the top, center of collection chamber 9 is provided with escape pipe 73.
The other end of sludge out pipe 3 is connected with sludge dewatering equipment 11 by a pressurized sludge pump 10.
Every helical layer rotating channel 5, be furnished with micro porous aeration head 71, be provided with pointed collection chamber 9 at the top of this layer, air is collected the back at this and is passed to outside the jar by tracheae 73, tracheae 73 feeds last layer after entering gas-liquid separator again, like this one passes straight through to top layer, drains into water-sealed tank 4 by escape pipe 8 at last, is discharged by water-sealed tank 4 tops again.Water seal can keep every helical layer rotating channel 5 that certain height is arranged, and water seal height is the collection chamber height.The water level of water seal is by the float valve 42 control stabilization height on the water inlet pipe 41.
Because just having entered the mixed solution dissolved oxygen of interior mud of tank body and bacterium is zero, is badly in need of a large amount of oxygen, contains a large amount of oxygen and just entered a jar intravital air, oxygen is effectively utilized behind the aeration, and aeration stirs mud and helps aerobic fermentation simultaneously.Owing to be the spiral structure, flowing of mud can be flowed in approximate wide passage, and constant flow rate is avoided the dead angle.
Mud is after the reaction of one-level aerobic fermentation, advance the last layer reaction zone, though the gas oxygen concentration of coming out at the first layer reaction zone reduce greatly because oxygen only spends 15%, also remain 85%, so this gas is introduced second layer reaction zone, because after the reaction of first district, the oxygen requirement of mud reduces, oxygen in the gas residue is enough to keep the aerobic amount in second district, second district is identical with first plot structure, and the atmospheric oxygen content in the effuser is also surplus, 85% * 85%=72.25%.So the one-level level is moved to the upper strata, makes that coefficient of oxygen utilization is the highest, reacts the most thorough, during to top layer, reacts completely.
Mud is the heavy metal ion stripping behind fermentation finished thoroughly1, pumps into sludge dewatering equipment 11 by force (forcing) pump 10, and after the dehydration, the heavy metal ion in the mud is removed.
