Device for preparing high-molecular aluminum salt coagulant by using high-salinity wastewater zero-discharge system sludge |
| abstract |
The utility model relates to a device for preparing a high-molecular aluminum salt coagulant by utilizing sludge of a high-salinity wastewater zero-discharge system, which is characterized by optimally designing and extracting a process flowRemoving impurities in the wastewater to obtain Al for promoting dechlorination precipitate 2 O 3 The content of the coagulant is determined by taking the dechlorination precipitate as a raw material, and the technical route for preparing the high molecular aluminum salt coagulant such as PAC or polyaluminium sulfate (PAS) and the like is adopted, so that the running cost of a zero-emission system is compensated while the solid waste is discharged. The prepared PAC or PAS alumina quality fraction, basicity, heavy metal content and other indexes respectively meet the requirements of the national standard of water treatment agent polyaluminum chloride (GB/T22627-2014) and the water treatment agent polyaluminum sulfate (HG/T5006-2016), and the concept of solid waste recycling can be realized. |
