Abstract
The invention discloses a kind of using haydite to the method for Treatment of Sludge, including：Deodorizing process is carried out to sludge first; then pH value adjusting processing is carried out to sludge again; curing agent is dosed into sludge after pH value adjusting processing and is stirred; then sludge is delivered in sedimentation basin and is precipitated; sludge after precipitation is carried out dehydrating using dehydration device; dewatered solidification sludge is placed on standing region and is stood, and the solidification sludge after the completion of standing is mixed with cement, haydite and water is added to stir, brick is compressed into using brick-making shaping machine after stirring evenly；Present invention process is simple, easy to implement, effectively improves the intensity after making brick from sludge, sludge is made to be effectively used, and reduces pollution of the sludge to environment.
Description
Technical field
The present invention relates to a kind of using haydite 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 haydite to Treatment of Sludge, 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 pollution of the sludge to environment.
The technical solution adopted in the present invention is：
A method of using haydite 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, haydite 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 84 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, haydite are in proportion 2.5：5：3 weight
Part proportioning mixing.
As present invention further optimization, the haydite is the particle 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 haydite 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, haydite 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 84 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,.
In the present embodiment, it is 48 hours or more that dewatered solidification sludge, which is placed on and stands time for being stood of region,.
In the present embodiment, solidification sludge and cement, haydite are in proportion 2.5：5：3 weight mixing.
Haydite in the present embodiment is the particle that grain size is less than 5mm.
Present invention process is simple, easy to implement, effectively improves the intensity after making brick from sludge, sludge is made to be effectively used,
Reduce pollution of the sludge to environment.
The above is only the preferred embodiment of patent of the present invention, it is noted that for the common skill of the art
For art personnel, under the premise of not departing from patent principle of the present invention, several improvements and modifications can also be made, these improve and
