Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to a thinning and dicing wastewater purification device. Background Art

[0002] The semiconductor industry requires a large amount of high-quality pure water in the manufacturing process, and generally requires a resistivity of IO MQ"cm or above high-purity water, and a large amount of wastewater is generated. The wastewater generated can be roughly divided into etching wastewater, photolithography wastewater, filter tube cleaning wastewater, reverse osmosis wastewater, ion exchange resin wastewater and chemical mechanical polishing (CMP) wastewater, etc. The main way of generating this kind of wastewater is that in the wafer thinning and dicing stage of the electronic packaging process, a large amount of ultrapure water is needed to wash the suspended microparticles or metal ions and other pollutants remaining on the surface of the wafer. The amount of pure water can reach about 15-20% of the total process water consumption, and the water consumption is large. In addition to a large amount of extremely fine nano-scale single-crystal silicon colloids that are not easy to settle and a small amount of coarse silicon, the wastewater discharged from the workshop contains no other impurities, extremely low salt content, and conductivity <100ys / cm, which is lower than the conductivity of groundwater or tap water of about 250ys / cm. The water quality is good, and the main pollutant is suspended solids (SS). At present, domestic enterprises generally dilute the thinning and dicing wastewater with a large amount of cleaning water, which wastes a lot of water resources, and the silicon impurities in the wastewater also cause certain pollution to the environment.
