Abstract

The invention discloses a comprehensive recycling method for solid waste water-quenched slag. The method comprises the following steps of (1) slurrying proportioned raw materials in a slurrying tank, and conveying slurry to a composite ionization reactor for reacting by a high-pressure pump after the slurry meets conveying required indicators; (2) carrying out subsequent treatment or comprehensive utilization on insolubles, which are produced from the composite ionization reactor and are the only produced waste residue of a whole process flow; (3) inputting a supernatant into an electric-membrane separation and concentration device, inputting the supernatant into a crystallizing tank for crystallizing after anions and cations are subjected to separation and concentration by using anion and cation membranes under the drive of electric field force, dehydrating and drying, thereby obtaining a series of products. According to the method, advanced processes of treating waste with waste are adopted, no waste gases, waste water and waste residues are discharged during comprehensive recycling, and the amount of solid waste digestion is 1,300 tons per day, so that the requirements on clean production and environmental protection are met. In addition, process procedures of the method all use electric energy, the aims of treating waste with waste, low cost and no pollution are realized, the technology is mature, and the process is reliable.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, in particular to a method for comprehensive recovery and utilization of solid waste water-quenched slag. Background technique [0002] According to statistics, there are more than 8,000 mines in China, and more than 10,000 tailing ponds have been built. By the end of 2007, the total amount of tailings had reached 8 billion tons. For every 1 ton of pig iron produced, 0.3 to 1 ton of slag will be discharged from China's iron and steel plants. The annual discharge of slag is as high as 600 million tons. Once such a huge amount of slag is improperly treated and discharged to the outside world, it will bring great harm to the natural world. The slag will pollute the air and water, and will also cause damage to the surrounding ecology. Pollution, such as soil pollution, vegetation destruction, etc., occupy a large amount of land. Iron tailings ponds will occupy a large amount of agricultu...
