Description

Spreading mechanism for organic solid waste treatment device

Technical Field

The application relates to the technical field of organic matter solid waste treatment devices, in particular to a material spreading mechanism for an organic matter solid waste treatment device.

Background

With the increasing importance of sewage treatment in various countries and the continuous construction of urban sewage treatment plants, the yield of sludge is continuously increased, and the rapid and effective treatment of sludge is still slow. The sludge has the characteristics of high water content, large content of pathogens, microorganisms and other harmful organisms, heavy metals, organic matters and the like, and secondary pollution to the environment can be caused if the sludge is not treated before being discharged.

The sludge treatment principle is to realize reduction, stabilization, harmlessness and recycling of sludge, wherein the sludge reduction is undoubtedly the key of subsequent treatment of sludge and the key point of sludge treatment. The sludge reduction can be realized by two ways, namely, the content of organic matters in the sludge is reduced, and the water content of the sludge is reduced. The second approach is simpler and easier to implement than the first approach, both technically and financially. The purpose of sludge dewatering is to remove a large amount of water from the sludge, thereby reducing its volume and weight, and facilitating the transportation and further processing of the sludge. Research shows that if the water content of the sludge is reduced from about 99.3 percent to 60 percent to 80 percent, the volume of the sludge can be reduced to 1/10 to 1/15 percent of the original volume, and the cost of transporting the sludge outside and the amount of percolate generated during further treatment are greatly reduced. At present, in the common sludge dewatering methods, mechanical dewatering is a method commonly adopted by various countries in the world, and the common dewatering machines comprise a vacuum filter, a plate-and-frame filter press, a belt filter press, a centrifuge and the like.
