Recycling treatment method for salt-containing wastewater

The invention relates to a recycling treatment method for salt-containing wastewater. The recycling treatment method is characterized by comprising the following steps: (1) carrying out desalting, concentrating and initial hard water removal on the salt-containing wastewater through a general electrodialyzer at first, returning obtained low-salt wastewater to a desalting process for preparing pure water, and carrying out deep hard water removal on high-salt wastewater through ion exchange; (2) pumping the preprocessed high-salt wastewater into a bipolar membrane electrodialyzer for recycling treatment, dissociating sodium chloride and water for greatly reducing the content of salt in the wastewater, and obtaining hydrochloric acid and sodium hydroxide at the same time; returning the obtained low-salt wastewater to a water concentration chamber of the general electrodialyzer for concentrating again. According to the recycling treatment method, the environmental pollution caused by direct discharge of the high-salt wastewater is avoided, wastes (salt) are turned into wealth (acid and alkali), the water recovery rate of a salt water removal process is increased, the integral water preparation cost is remarkably reduced, and good economic and social benefits are achieved.

Warm-mixed auxiliary agent for asphalt mixture and preparation method thereof

The invention relates to a warm-mixed auxiliary agent for asphalt mixture. The auxiliary agent is formed by uniformly mixing 93 to 97 percent of synthetic zeolite with 3 to 7 percent of granular sodium sulfate decahydrate by weight, wherein the synthetic zeolite includes 15 to 22 percent of crystal water, and the sodium sulfate decahydrate includes 55.9 percent of crystal water. Under normal temperature, the auxiliary agent is mixed with other raw materials according to the content of 0.3 to 0.5 percent of the total mass of the mixture, thereby preparing the product of the warm-mixed asphalt mixture; and other raw materials are 150 to 165 DEG C asphalt, 140 to 180 DEG C aggregate and mineral powder filling materials. During the blending of the mixture, the warm-mixed addition agent and the heated asphalt are added simultaneously, great amount of vapor generated by the moisture-containing auxiliary agent are released, which results in volumetric expansion of the asphalt, thereby forming foamed asphalt; meanwhile, the workability of the asphalt can be enhanced, the blending and mold temperature of the mixture can be reduced by 15 to 25 DEG C, exhaust emission can be effectively reduced, energy consumption is lowered, the aging of asphalt during blending is reduced, and the auxiliary agent has the advantages of simple preparation and low cost.

Underground storey-adding process of frame structural building by one-by-one independent foundation underpinning method

The invention relates to an underground storey-adding process of a frame structural building by a one-by-one independent foundation underpinning method. In the process, top beams and top supports of the building with a proposed basement and columns and foundations of the completed basement jointly support an upper structure of the building, and then earth excavation and construction of the columns and the foundations of the residual uncompleted basement are continuously carried out. Earth excavation and top support are simultaneously performed; after the original foundations are removed, the load of the upper frame columns is transferred to the adjacent foundations around the columns through the top beams and transferred to earth through the foundations; and after new foundations and an lower ground level underground frame column are constructed, the load of the upper frame columns can be jointly supported by the new foundations, beam supports and the adjacent foundations. Compared with 'a slab foundation underpinning method' in which the upper structure is simply supported by soil mass under slabs, the method is more reliable and can complete underground storey-adding in areas with worse soil property; compared with the underpinning mode of removing the foundations of the whole building simultaneously, the method is more safe; and even though engineering accidents happen, the building is locally but not integrally unstable.
