| titleOfInvention | A kind of alkali residue harmless treatment of soda ash produced by ammonia-alkali method and its resource utilization method |
| abstract | The invention belongs to the technical field of comprehensive treatment of industrial wastes, and in particular relates to a method for harmless treatment and resource utilization of alkali residues for producing soda ash by an ammonia-alkali method. In view of the characteristics of high salinity, high ammonia nitrogen, high chloride ion, high viscosity and high moisture content of the soda ash produced by the ammonia-soda process, it is very difficult to treat it harmlessly and as a resource at present. The invention provides a harmless treatment method for soda ash produced by the ammonia-alkali method, which comprises the following steps of concentrating and/or adding water to the soda slag produced by the ammonia-alkali method for producing soda ash, and then adding a composite treatment agent and a flocculant in sequence, and concentrating and dehydrating. , obtain the alkali residue that is harmless, reduced and recycled after treatment, as well as recycled water or water that meets the standard. The invention is suitable for the treatment of the alkali residue produced by the production of soda ash by the ammonia-alkali method, especially for the treatment of the alkali residue with high alkalinity, high ammonia nitrogen, high salinity, high water content, strong colloid, high viscosity, more bound water and strong hydrophilicity and resource utilization. |
