Problems solved by technology

[0005] Although the current sludge treatment system can process and deliver the sludge, it still has the following defects: the moisture content of the sludge in the sludge tank is constantly changing in the range of 95%-99%, which causes the centrifugal dehydrator of the dehydration treatment system to The operating frequency is constantly changing, requiring special personnel to manage, and it is easy to block the material, causing the system to fail to operate normally

Embodiment Construction

[0045] Such as figure 1 Shown is the first embodiment of the sludge treatment system of the present invention, which can be used for the evaporation raffinate after the evaporation treatment of the garbage leachate, the sludge and scum produced by the pretreatment of the leachate, etc.; of course, the sludge The treatment system can also be used for the treatment of other aqueous sludge.

[0046] As shown in the figure, the sludge treatment system includes a sludge tank 11, a sludge concentration treatment device, a dehydration treatment system, etc. connected in sequence; of course, it may also include a mud bucket 18, a storage tank 17, etc. connected to the dehydration treatment system.

[0047] The sludge pool 11 is connected to sludge, and a stirring device (such as a submersible mixer or others) can be set in the sludge pool 11 to stir and mix the sludge entering the sludge pool 11, and then pump it out to Sludge concentration treatment device. When the sludge is sent ...

Abstract

A sludge treatment system comprises a sludge pool (11) for receiving sludge, and a dehydration treatment system for performing dehydration treatment on the sludge. A sludge concentration tank (12) is further disposed between the sludge pool (11) and the dehydration treatment system. Sludge discharged from the sludge pool enters the sludge concentration tank (12) to undergo concentration treatment. An upper clear liquid of the sludge concentration tank (12) is discharged, and the concentrated sludge enters the dehydration treatment system. The sludge from the sludge pool (11) first enters the sludge concentration tank (12) to undergo concentration treatment, and then is discharged to the dehydration treatment system. Further, the sludge treatment system can work together with a sewage treatment system to treat sludge in a sewage pre-treatment system, and a filtered liquid after the treatment of the sludge can be used in the sewage pre-treatment system, so as to be effectively recycled, thereby reducing harm to the environment.

Description

technical field [0001] The present invention relates to a treatment system and method for sludge and sewage, more specifically, a sludge treatment system, sewage and sludge treatment system and method that can be used in waste incineration plants or waste incineration power plants. Background technique [0002] With the improvement of living standards and the rapid development of modern cities, the problem of domestic waste pollution has become increasingly prominent. Domestic waste treatment methods mainly include incineration, composting, mechanical treatment and landfill. The traditional landfill treatment of municipal solid waste is subject to more and more restrictions. According to the basic principles of harmlessness, reduction and recycling of municipal solid waste, domestic waste incineration power generation has become a solution to urban domestic waste in recent years. New direction, the construction of waste incineration plants has developed rapidly in recent ye...
