Abstract

The invention provides an ammonia-containing wastewater recycling system and a desulfurization and denitrification dedusting system, and belongs to the field of wastewater treatment. The ammonia-containing wastewater recycling system comprises a precipitation tank, dewatering equipment, evaporating and crystallizing equipment, a liquid ammonia supplementing device and a liquid recycling tank, wherein the precipitation tank is used for receiving desulfurization and denitrification wastewater in a desulfurization and denitrification deduster, and is connected with the dewatering equipment; the dewatering equipment is connected with the evaporating and crystallizing equipment, and the evaporating and crystallizing equipment is connected with the liquid recycling tank; the liquid recycling tank can be connected with the desulfurization and denitrification deduster, and is connected with the liquid ammonia supplementing device. The ammonia-containing wastewater recycling system has the advantages that a liquid part of the desulfurization and denitrification wastewater is recycled by the ammonia-containing wastewater recycling system, and precipitate is condensed and purified and can be directly applied to fertilizers and chemical engineering, so that the utilization rate of resources in the whole desulfurization and denitrification dedusting process is greatly improved; by arranging the desulfurization and denitrification dedusting system, the desulfurization and denitrification dedusting rate is improved.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a recycling system for ammonia-containing wastewater and a desulfurization, denitrification and dust removal system. Background technique [0002] Industrial kiln flue gas in building materials, thermal power generation, steel, non-ferrous smelting and other industries has the characteristics of high temperature and high concentration. The flue gas emitted contains a large amount of smoke and sulfide, which seriously pollutes the atmosphere and affects human health. The diameter of PM2.5 particles in the flue gas is smaller than or equal to PM2.5, because of its large specific surface area, it can absorb a variety of toxic and harmful substances. , cause inflammation, asthma and other respiratory diseases, increase the morbidity and mortality of heart disease, and have potential carcinogenicity. Therefore, it has a greater impact on human health and atmospheric environmental ...
