Description
Technical field
The present invention relates to a kind of using sintered porous plastics to the method for Treatment of Sludge, belongs to technical field of sludge treatment.
Background technology
Sludge is the product after sewage disposal, is that one kind is made of organic debris, microorganism, inorganic particle, colloid etc.
Extremely complex heterogeneous body, the key property of sludge is that moisture content may be up to 99% or more, and high organic content is easy corruption
Change smelly, and particle is thinner, and proportion is smaller, jelly liquid, it is the concentrated thing between liquid and solid, Ke Yiyong
Pump transport, but it is difficult to be separated by solid-liquid separation by sedimentation, and sludge is by sources divided mainly to have domestic sewage sludge, industrial wastewater dirty
Mud and copper water-supply pipe；Dividing sludge mainly by processing method and separation process has following several classes：
Primary sludge：Refer to the sediment generated in sewage stage treatment process；
Activated sludge：Refer to the sediment that activated sludge method processing technique secondary settling tank generates；
Humus sludge：Refer to biofilm（Such as biofilter, biological rotating disk, part biological contact-oxidation pool）Sewage treatment process
The sediment that middle secondary sedimentation tank generates；
Chemical sludge：Refer to chemically enchanced primary treatment（Or tertiary treatment）The sludge generated afterwards；
Have much to the processing method of sludge at present, wherein be rapidly developed the processing mode of sludge curing brickmaking, mainly
The reason is that environmental pollution can be effectively reduced using making brick from sludge, sludge is made to be effectively used, but current making brick from sludge
Method is irregular, and brickmaking effect is undesirable, and the intensity after making brick from sludge cannot meet technology requirement.
Invention content
To solve the deficiencies in the prior art, the present invention provides a kind of method using sintered porous plastics to Treatment of Sludge,
It is simple for process, it is easy to implement, the intensity after making brick from sludge is effectively improved, sludge is made to be effectively used, reduces sludge to environment
Pollution.
The technical solution adopted in the present invention is：
A method of using sintered porous plastics to Treatment of Sludge, including：
Deodorizing process is carried out to sludge first, pH value adjusting processing then is carried out to sludge again, to sludge after pH value adjusting processing
In dose curing agent and stir, then sludge is delivered in sedimentation basin and is precipitated, the sludge after precipitation utilizes dehydration device
Be carried out dehydrating, dewatered solidification sludge be placed on stand region stood, by after the completion of standing solidification sludge with
Cement, sintered porous plastics mix and water are added to stir, and brick is compressed into using brick-making shaping machine after stirring evenly.
As present invention further optimization, the curing agent and the process of stirring dosed into sludge is to be in temperature
It is stirred in the environment of 81 degrees Celsius.
As present invention further optimization, the curing agent and the time of stirring dosed into sludge is 1.5 hours.
As present invention further optimization, it is 24 small that the sludge, which is delivered to the time precipitated in sedimentation basin,
When.
As present invention further optimization, the dewatered solidification sludge be placed on stand region stood when
Between be 48 hours or more.
As present invention further optimization, the solidification sludge and cement, sintered porous plastics are in proportion 3：7：3
Weight mixing.
As present invention further optimization, the sintered porous plastics are the particles that grain size is less than 5mm.
The beneficial effects of the present invention are：It is simple for process, it is easy to implement, the intensity after making brick from sludge is effectively improved, dirt is made
Mud is effectively used, and reduces pollution of the sludge to environment.
Specific implementation mode：
Specific introduction is done to the present invention with reference to embodiment.
The present embodiment is a kind of method using sintered porous plastics to Treatment of Sludge, including：
Deodorizing process is carried out to sludge first, pH value adjusting processing then is carried out to sludge again, to sludge after pH value adjusting processing
In dose curing agent and stir, then sludge is delivered in sedimentation basin and is precipitated, the sludge after precipitation utilizes dehydration device
Be carried out dehydrating, dewatered solidification sludge be placed on stand region stood, by after the completion of standing solidification sludge with
Cement, sintered porous plastics mix and water are added to stir, and brick is compressed into using brick-making shaping machine after stirring evenly.
The present embodiment, which doses curing agent and the process of stirring into sludge, to be carried out in the environment of temperature is 81 degrees Celsius
Stirring.
It is 1.5 hours that the present embodiment, which doses curing agent and the time of stirring into sludge,.
In the present embodiment, it is 24 hours that sludge, which is delivered to the time precipitated in sedimentation basin,.
