Accompanying drawing explanation
Fig. 1 is the distribution schematic diagram of this utility model sludge modification processing system.
Detailed description of the invention
In order to make the technical solution of the utility model more clearly to show, the utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, it is provided that a kind of sludge modification processing system, for processing the mud through materializing strategy postprecipitation.Described sludge modification processing system includes the first regulating reservoir 10, elevator pump (not shown), preliminary sedimentation tank 20, sludge pump (not shown), concentration basin 30, mud drying device 40 and the second regulating reservoir 50, described first regulating reservoir 10 is connected to preliminary sedimentation tank 20 by elevator pump, described preliminary sedimentation tank 20 is connected to concentration basin 30 by sludge pump, described concentration basin 30 is communicated in described second regulating reservoir 50 and mud drying device 40, described mud drying device 40 is connected to described second regulating reservoir 50, and described second regulating reservoir 50 is connected to described preliminary sedimentation tank 20 by elevator pump.
Described sludge modification processing system also includes modifying agent and chemicals dosing plant, described chemicals dosing plant includes constant feeder, molten medicine cylinder, agitating device and dosing pump, described modifying agent includes PAC (aluminium polychlorid) and PAM (polyacrylamide), modifying agent is through described batcher, molten medicine cylinder, after agitating device one system processed, added to described preliminary sedimentation tank 20 and concentration basin 30 by described dosing pump, so that a part of mud becomes graininess, increase sludge density, further mud is carried out Gravity Separation in preliminary sedimentation tank 20, make sludge settling at the bottom of pond, the particle diameter of settled sludge granule is increased in concentration basin 30, thus accelerate sedimentation velocity.
Described preliminary sedimentation tank 20 includes inhalant region, mud district and exhalant region, described mud self-regulation pond 10 enters described inhalant region, appropriate modifier is added at this inhalant region, floc sludge does Gravity Separation in preliminary sedimentation tank and is deposited at the bottom of dirty pond, and combine in mud district, the water that preliminary sedimentation tank is separated is expelled to sewage disposal system from exhalant region, and the mud in mud district is evacuated in described concentration basin 30 by described sludge pump.It is provided with mud scraper in described concentration basin 30, in concentration basin 30, adds appropriate modifier, to accelerate sludge settling speed simultaneously.Mud in concentration basin after preliminary modification, form the stable sludge blanket of granularity and supernatant.Described supernatant is drained in described second regulating reservoir 50 by pipeline, and the mud in concentration basin carries out filter-press dehydration in being delivered to mud drying device 40.
In the present embodiment, described mud drying device 40 includes that a filter press, described filter press carry out processed to mud, forms dewatered sludge and the modifying agent of part residual after dehydration.This residual modifying agent mixes with supernatant in draining into described second regulating reservoir by pipeline, Gravity Separation is carried out in being extracted into preliminary sedimentation tank 20 by described elevator pump again, in mud after precipitation suction concentration basin 30 again, circulate according to this, by constantly extending sludge retention and incorporation time, floc sludge is all modified as the mud that granularity is stable the most at last, effectively raises the dewatering efficiency of filter press.
