Detailed description of the invention
Fig. 1 is the flow diagram of the present embodiment sludge treatment technique of the present invention.
Specific embodiment
With reference to the accompanying drawings and examples, the present invention will be described in detail.
A kind of sludge solidification treatment process, as shown in Figure 1, comprising the following steps:
The first step is dug out the mud in river by dredger；
Mud is delivered to sludge treatment station by the lift pump on dredger and the dredging tube for connecting lift pump by second step；
Third step carries out separating treatment to the solid refuse in mud by the garbage cleaning device in sludge treatment station；
The mud that solid refuse is removed in third step is carried out dehydrating and curing processing by filter press by the 4th step.
Specifically, the dredger in the first step includes grab boat and cutter suction dredger.For river, the water surface is opposite
It is wider, when cannot be truncated or carry out dry pool dredging, mud excavation, usual feelings are carried out by grab boat and cutter suction dredger
Rough measurement first can be carried out to riverway sludge depth under condition, then carry out preliminary excavation adjustment, and be equipped on dredger
GPS and echo sounder are precisely controlled mud depth elevation by GPS and echo sounder, can be accurately by river
In mud dig out, without damage riverbed structure.
Specifically, the dredging tube in second step is connected by telescopic float tube waterborne with land bank pipe.Float tube waterborne is logical
It is often that interval adds buoy on plastic conduit, so that float tube waterborne be made to swim on the water surface.
Specifically, the garbage cleaning device in third step is rubbish sand-stone separator.It can by rubbish sand-stone separator
The biggish solid refuse in mud is quickly subjected to separating treatment, avoids the efficiency for influencing sludge solidification.
Specifically, first pass through settling tank before the mud in the 4th step is handled by filter press and preliminary sedimentation is carried out to mud,
And cleaning is filtered to the rubbish floated in settling tank by filter screen, then the moisture after silt deposit is discharged, to subtract
Moisture in few mud, improves subsequent sludge solidification efficiency.Multistage settling can be set according to mud water content situation in settling tank
Pond.
Mud in 4th step by settling tank precipitating is pumped into mud conditioner by water pump again, and flocculation is added
Agent is carried out dehydrating mud.The mud in mud conditioner is stirred by flocculant uniformly mixed, is then dehydrated
Processing, the moisture content being further reduced in mud.
Mud in 4th step Jing Guo mud conditioner dehydration is sent into further dehydration in thickener.By dense
Contracting machine carries out further dehydration to mud, further decreases the moisture in mud.It is dehydrated in 4th step by thickener
The mud of processing is re-fed into filter press, while being added curing agent and being carried out dehydrating and curing processing.Curing agent in the present embodiment by
The group of following weight percent meter is grouped as: cement 12%, quick lime 15%, flyash 20%, calcium lignosulfonate 8%, swollen
Swollen vermiculite power 20%, polyaluminium chloride 8%, bentonite 5%, flake asbestos 4%, desulfurized gypsum 4% and sodium metasilicate 4%.It is dehydrated
The mud of processing is sent into filter press, then curing agent is put into filter press, sludge solidification processing is carried out, to save at mud
Manage cost.
