Abstract
The invention discloses it is a kind of using natural fiber 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, pH value adjusts to handle and doses curing agent in backward sludge and stir, then sludge is delivered in sedimentation basin and 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 with natural fiber, clay is mixed 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 it is a kind of using natural fiber to the method for Treatment of Sludge, belong 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 more than 99%, and high organic content is easily rotten
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 carry out separation of solid and liquid by sedimentation, and sludge is by sources divided mainly to have domestic sewage sludge, and industrial wastewater is dirty
Mud and copper water-supply pipe；Sludge is divided mainly there are following a few classes by processing method and separation process：
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, the processing mode of sludge curing brickmaking is rapidly developed, 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 provide it is a kind of using natural fiber to the method for Treatment of Sludge, technique
Simply, it is easy to implement, the intensity after making brick from sludge is effectively improved, sludge is made to be effectively used, reduces dirt of the sludge to environment
Dye.
The technical solution adopted in the present invention is：
It is a kind of using natural fiber to the method for Treatment of Sludge, including：
Deodorizing process is carried out to sludge first, then carries out pH value adjusting processing to sludge again, pH value, which is adjusted, handles backward sludge
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 the solidification sludge after the completion of standing with
Natural fiber, clay 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 process that curing agent is dosed into sludge and is stirred is to be in temperature
It is stirred in the environment of 68 degrees Celsius.
As present invention further optimization, the time that curing agent is dosed into sludge and is stirred is 1 hour.
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 natural fiber, clay are in proportion 2.5：3：10
Weight mixing.
As present invention further optimization, the joint length of the natural fiber is less than 6cm.
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, makes dirt
Mud is effectively used, and reduces pollution of the sludge to environment.
Specific embodiment：
Specific introduction is done to the present invention with reference to embodiment.
The present embodiment is a kind of method using natural fiber to Treatment of Sludge, including：
Deodorizing process is carried out to sludge first, then carries out pH value adjusting processing to sludge again, pH value, which is adjusted, handles backward sludge
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 the solidification sludge after the completion of standing with
Natural fiber, clay mix and water are added to stir, and brick is compressed into using brick-making shaping machine after stirring evenly.
The process that the present embodiment is dosed curing agent into sludge and stirred is to carry out in the environment of 68 degrees Celsius in temperature
Stirring.
The time that the present embodiment is dosed curing agent into sludge and stirred is 1 hour.
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 natural fiber, clay are in proportion 2.5：3：10 weight mixing.
The joint length of natural fiber is less than 6cm in the present embodiment.
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 patent principle of the present invention is not departed from, several improvements and modifications can also be made, these improve and
