Abstract
The invention relates to the field of environmental protection treatment, in particular to a harmless utilization method of waste residues generated by recycling hazardous waste inorganic salts, wherein sodium benzene sulfinate, ammonium polyacrylate and sulfuric acid are added into the waste residues, then the waste residues are heated at high temperature, organic hazardous wastes such as medicines, pesticides and the like remained in the waste residues can be effectively carbonized, then the treated waste residues are mixed with rapid hardening cement, an early strength agent, aluminum powder and the like, and the prepared finished product can be used for manufacturing wall bricks with light weight and high strength; the added early strength agent can accelerate the curing time and eliminate the adverse effect on a curing system brought by the introduction of the waste residue, and the method belongs to a harmless treatment process, not only can solve the problem of difficult waste residue treatment, but also can utilize the waste residue efficiently, safely and environmentally.
Description
Technical Field
The invention relates to the field of environmental protection treatment, in particular to a harmless utilization method of waste residues generated by recycling hazardous waste inorganic salts.
Background
At present, management departments at all levels of the state and the province pay attention to the research and industrialization of the harmless treatment and resource utilization process technology of hazardous waste inorganic salt, actively organize the research and development and application of new processes, and actively add each enterprise into the process research. The waste water is a by-product which is inevitably generated in the treatment process, and how to harmlessly treat the generated waste residues is also a very critical subject.
At present, the domestic treatment methods for the byproduct slag salt in chemical production mainly comprise four methods: (1) washing salt with water or organic solvent to remove impurities, and using 75% of the treated salt in chlor-alkali industry. The method is more suitable for the byproduct slag salt with low impurity content and single impurity component, and has the defects of large consumption of washing water or organic solvent and the problem of secondary pollution such as retreatment and the like; in addition, the impurity content in the byproduct slag salt is often unstable, the dosage of washing water or solvent is difficult to control, the process flow is complicated, impurities are difficult to clean, and industrialization is difficult to realize. And (2) carrying out high-temperature treatment on the slag salt by using a high-temperature treatment method, so that organic impurities contained in the slag salt are oxidized into CO2, CO and H2O gas at high temperature, thereby achieving the purpose of removing the organic impurities. The key point of the method lies in the selection of decomposition oxidation combustion equipment. In China, hot working equipment such as a rotary kiln, a fluidized bed furnace and the like is reported, but the industrial problems of salt agglomeration, caking and the like at high temperature are difficult to solve. The method is simple and easy to implement, low in cost and high in product quality. And (3) preparing a soda ash method, namely preparing a saturated saline water solution from the slag salt, introducing ammonia gas and carbon dioxide gas or directly adding solid ammonium bicarbonate under certain conditions, reacting for a period of time, crystallizing to separate out solid sodium bicarbonate, separating, washing, performing pyrolysis to obtain soda ash, separating mother liquor mainly containing ammonium chloride, adding the slag salt, freezing to separate out the ammonium chloride, and circulating to a soda ash preparation process. The key of the method is to improve the reaction yield and solve the problem of influence of organic impurities in the slag salt on the product quality. The method is particularly suitable for enterprises which need soda ash or ammonium chloride, can recycle waste residues and realize circular economy. The process has the advantages of small investment, simple process and low cost, but organic matters in the product are not removed, and the product still belongs to hazardous waste; meanwhile, the process is not feasible due to the limitation of product technical standards. And (4) dissolving the slag salt into a saturated solution by a solution denitrification method, and then selecting a denitrification agent to remove nitrogen in the solution so as to meet the requirement of chlor-alkali on nitrogen content of the salt water, wherein the method needs to add the denitrification agent, so that the cost is higher. In particular, toxic organic matters in the slag salt can not be removed, and the recycling of the salt can not be realized. The treatment of the slag salt is to recover the salt and recycle the salt to the original production process from the viewpoint of resource recycling.

The corn belongs to high-stalk crops, and the area of the stalks is large and the quantity of the stalks is large. When the corn is harvested, the moisture content of the straws is high, the straws are not convenient to store and transport, and the straws are messy and disordered after being dried completely and are not easy to collect and concentrate.
