This invention relates to a method to reduce ammonia nitrogen pollution during the modification process of zeolite. The method comprises, in the process, exchanging sodium in the zeolite with potassium compounds, and then exchanging zeolite with ammonium salts. The ratio of potassium compounds to zeolite is 0.01~0.5, reaction temperature is 5-100DEG C, and the reaction time is 0.1-6 hours. The method will not increase the modification cost and can reduce ammonium salt use by 50%, therefore reducing ammonia nitrogen pollution and the burden of ammonia nitrogen wastewater treatment process and investment. It is an environmental technology for zeolite modification. The prepared zeolite catalyst has lower sodium content with catalytic activity basically unchanged or increased.

The invention discloses a preparation method for low-sodium-salt spiced beef leisure food. The raw material for preparing low-sodium-salt spiced beef is fresh beef or frozen beef. The preparation method comprises the following steps of performing vacuum rolling and pickling on the fresh beef or the defrozen beef by using composite low-sodium salt, marinating the beef in boiled marinade, and finally slicing and packaging as well as sterilizing the beef to obtain the ready-to-eat spiced beef packaged products (leisure food). Compared with common spiced beef, the finished product prepared tastes delicious, and the sodium content is obviously reduced; nitrite is not used; the contents of potassium ions and calcium ions are also increased; nutrients of the food are strengthened; the health of a human body is facilitated; the preparation method is particularly suitable for nutrient healthy meat products eaten by people suffering from hypertension.

The invention discloses a treating method of tailings generated from vanadium extraction. The treating method adopts the technical scheme as follows: through the adoption of ions of alkaline-earth metals, sodium with stronger activity in the tailings generated from vanadium extraction is replaced to form sodium ions to enter a solution, so that the purpose of sodium removal is achieved; through the addition of a dispersing agent, the clustering phenomenon between particles is reduced, so that the removing rate of sodium is further improved. According to the treating method of the tailings generated from vanadium extraction, the sodium content can be significantly decreased, and sodium is replaced by alkaline-earth metals which have a less influence on smelting, so that the fact that the leaching residues are further subjected to blast furnace ironmaking is possible, and the efficient utilization of the tailings generated from vanadium extraction is achieved; a large amount of acid solution is avoided, and the recycle of a leaching solution is facilitated; the leaching solution can be used for leaching vanadium from vanadium slag; the removing rate of sodium in the leaching residues can be 40-70% above.
