Talk about construction waste.，Most of the things that emerge in the brain are decoration garbage.、Demolition and construction garbage，Residual mud and dregs are often neglected.。In fact, in the field of construction waste，The proportion of residual mud and dregs is the big one.！According to relevant data,，The proportion of dregs and residual mud in construction waste in Japan is 70%Left and right，China's figure is also as high as 60.%-75%。

The residual mud soil contains a large amount of water and surfactant，High mobility，If not treated harmlessly，It not only has a negative impact on the surrounding water and soil environment，Bring great pressure to the ecological environment，And has great potential safety hazard.，It may even cause landslides.。The huge landslide accident in Guangming New District of Shenzhen in 2015 has sounded the alarm for the world.——Use of landfills“Against nature”The disposal method of residual mud and soil in the process is not advisable.。How to scientifically accept residual mud and dregs？How can we realize the resource utilization of dregs?？We urgently need to find new ways to deal with it.，Change the traditional processing mode.。

As one of the earliest service providers in the field of construction waste treatment in China,，As early as 2016, Nanfang Road Machinery has invested in the research of residual mud and soil recycling.，And in just a few years, efforts have been made to break through the key technologies of the short board.，Solved“Stuck in the neck”Question，Creatively put forward three targeted solutions.。

One、Mud cake improvement——Sanding

Residual filter pressing mud cake after pretreatment of engineering mud and muck，Low economic value，How to deal with consumption has become an industry problem.。Southern Road Machinery excavates its environmental protection value and economic value.，Proposed improved solution for mud cake solidification。

△Improved solution for mud cake of southern road machine

The solution is primarily to leverage theRMMud cake improvement all-in-one machine，Crushing the mud cakes，And to the mud、Adding a curing agent into viscous raw materials such as mud cakes and the like。Aft that comprehensive treatment of multiple working procedure,，So that that mud cake of the slurry are sanded，Into pellets of a certain strength，And finally serve as a water-stable layer of that subgrade.、Subbase、Filling materials for rolling compaction of low-strength works such as dam filling。Regeneration of mud cake。

Two、Regeneration and granulation——Agglomerate

After pretreatment of residual mud and soil,，There will be some contaminated waste mud cakes left.、Industrial waste and other materials。These materials are discharged directly.、Stack，Will cause serious harm to the environment。In response to this situation，Nanfang Road Machinery Co., Ltd. Proposes Regenerative Granulation Solution。

This solution is for contaminated mud cakes、Fine treatment of industrial wastes，Admixtures such as chelating agents are fully blended into the wastes，Stabilizing and granulating。It's breaking up、Mixing、Pelleting、In the process of improvement treatment such as granulation，Can effectively regulate and inhibit the dissolution of harmful substances，The finished product is passivated、Modification、Strengthen to meet the standards of landfill storage or recycling.。

Finished products treated by Nanfang Road Machinery Regenerative Granulation Solution，Can be use as sponge city filter material、Materials such as gravel along the road really realize the waste dregs.“Reduction、Resource utilization、Recycle and reuse”。

Three、Fluidized treatment——Liquid

Subway shield、The engineering mud produced by construction methods such as rotary excavation and piling of foundation is also a part of the residual mud and dregs.。The moisture content of this type of residual soil is extremely high.，And is in a fluid state in a natural state。

Solution for Fluidized Soil Treatment of Nanfang Road Machine，By dissolving mud、Mud mixing、Ingredients、Mixing and other process and method combination，So that that engineer slurry is converted into slurry with certain fluidity、And can reach a certain strength after solidification.，The disposal cost is greatly reduced.，Enhance the added value of regeneration。

With the increasing production of residual mud and soil and the increasing attention to its resource treatment in China.，The degree of resource utilization of residual mud and soil in China will continue to improve.，It has gradually developed into a virtuous circle of environmental protection.。
On the basis of years of dedicated exploration, Nanfang Road Machinery has put forward the solution of residual mud and dregs.，Can deal with a variety of complex working conditions，It is conducive to improving the reuse rate，So as to increase the profits of the industry.，Meet the current market demand。
