Description

V. Description of the invention (1) The present invention relates to a method and a device for steel foil, the soil J = 3 of the mud is treated as a resource, dried and dehydrated, and stable and tempered raw materials are added; the sludge is granulated and dried The aforementioned sludge is adjusted for the purpose = fumigation ^ to reduce the amount of sludge and reuse it. · Fang has become a source of various materials and related supervisors :::: f: Legacy environmental issues have also caused the industry and relevant authorities to test sludge mining problems and test the industry—f plastics company is wrong ? The solidification method is approved by the government, and the waste disposal company that commissions the removal and removal is assisted by the treatment. The ultimate responsibility is based on the lack of / Dong Xun 1 early to take the evening can only come forward to deal with too many political factors. It can be processed in the direction of green production and waste management to ensure the future cost = and there is no need to worry about similar mercury sludge incidents. At this stage, toxic or heavy metal sludge is mostly treated by solidification, but solidification is not a panacea for sludge treatment. Although the curing technology is mature, the way of oralization is simple. However, due to the differences in the manufacturing processes of domestic factories = large, there are many types of sludge. The chemical changes and adaptability between this sludge and the curing agent have become extremely difficult to grasp and control. Disposal is also a major problem, and the hidden risks are not small. The sludge produced during the copper foil production process is a toxic substance of heavy metals in the pipeline. As can be seen from the foregoing, curing is by no means the best strategy. Due to the comprehensive compounds of sulfur, chlorine, acid, and alkali, it is easy to change with water and air, and solidify Post stability

503224 V. Description of the invention (2) The capacity that is difficult to grasp is as high as difficult to implement, due to reasons. The cost of chemical and physical treatment of sludge is left behind for generations. Metal sludge materials are granulated, dried sludge is reduced, and material resources. The sludge resource recycling machine, drying rotary screening equipment and the invention The purpose of application of the method group The polychlorinated polychloride of the present invention is generally shallow, and except for several times, this method has the best multi-path properties. The cost is high. A piece of pure land. The source treatment of the present invention is dry and dehydrated, and then the aforementioned method is used. The other main processing equipment is kiln, mixed washing cooling, copper foil process, and 〇 copper foil process, aluminum flocculation to dark green copper foil process

The coating method is used to fix the treatment. However, this method will increase the rayon in the bay area. This method will also stagnate the treatment method. The sludge is modified by modifying the resources in sequence, and then blending other raw materials to change. Pollution can be 100% resource-based. Although it is more resource-based, it can make the industry worry-free, and in the future, it should be a way to choose. The main purpose is to provide a "copper foil heavy process", which is mainly adding sludge containing heavy metals to stable and quenched and tempered raw materials and then calcined in the kiln to adjust the sludge formulation for the purpose. A "heavy metal in copper foil manufacturing process", which mainly includes agitating conveyor, feeder, calcined rotary smoker, grinder, iron removal equipment, and tower crane. Recycling of sludge, in order to use different devices, each stage exerts the application effect to achieve resource sludge. It is the residue after the addition of PAC during the copper foil process wastewater treatment. , Or from gray to black, with a water content of 70-85%, and copper after processing produced by other copper processes

Page 5 5. Description of the invention (3) Sludge such as heavy metals can be treated. According to the present invention, the content of the two components after the sludge is resourced is different, and the c range can be selected in different original ranges based on the application in the sludge industry. After application, it can be applied to the ceramics-filling and glass-making industry; Mainly refer to the first picture of the flow chart of the mud after the bamboo mud is carried over or pressed. The copper processing company 1 solidifies the principle: f wraps the clothes in a space bag, and the dirt is packed in the space bag. η =: The heavy metal sludge resource in the manufacturing process is shown in the figure. The original treatment method includes k stand. The sludge is made into uniform round rods. [Generally known systems are mostly block-shaped and formed. The stacking method is used for drying, and it is easy to make the external water t evaporate unevenly. When the block size and the heat of the stack are different, the drying speed on the surface is different from that on the inside, which greatly affects the drying rate. Granulate the sludge before drying to make it evenly distributed during drying, which increases the drying effect and achieves fast drying effect]. Drying and dehydration: remove the water from the round rod granular sludge, dry and dehydrate the original sludge containing -85% to a sludge with a moisture content of 30%. Add stable and quenched and tempered raw materials: Add stable and tempered raw materials to the dry sludge 'so that the calcination operation in the next step can accelerate the anti-uniformity of the calcination. Calcination: The sludge is calcined into stable oxides, so that the amount ′ is only about 20% of the stable oxides of the original sludge. The basic resources of the various resources in different areas of the foil production process are then transferred to solid dyeing. The copper foil sludge of the present invention is processed into sludge. The sludge in the sludge is treated to make a surface area of round rods. Less
