There are large amount of ammonia in coking wastewater. It is a good recycling desulfurizer. Sintering flue gas has the characteristics, such as large amount of, low SO2 concentration, great changes of operation load. Treating sintering flue gas with coking wastewater can attain the destination of treating waste with waste. This paper adopts a spray tower countercurrent device, and SO2 concentration in the entrance and exit flue gas is on line detected by an automatic flue gas detection instrument. The paper studies on the change rule of SO2 concentration in the process of treating sintering flue gas using coking wastewater, and the influence of SO2 initial concentration in sintering flue gas to the desulfurization rate. The results show that after being treated the sintering flue gas can reach the emission standard for air pollutants of iron and steel industry.

Crystalline Matrix

All incineration and other thermal treatment technologies produce flue gas treatment residues (FGTR) that require specialised treatment and disposal. In the United Kingdom the FGTR arising from municipal solid waste incineration is classified as a hazardous (special) waste. This is primarily due to the irritant properties of chloride, but also due to the content of heavy metals. These wastes must be handled, transported & disposed of in accordance with the Special Waste Regulations 1996 and are disposed into highly engineered landfill sites, which isolate the material from the environment. The low levels of trace elements in the FGTR mean that the recycling of the metallic elements is not economic. Control through stabilisation and encapsulation in a crystalline matrix converts the FGTR primary form from a powder into solid block form. The use of a novel metal matrix encapsulation (MME) process allows low level engineering processes to be employed, increasing a range of reuse options combined with long-term improved storage.

The present status of iron and steel industry of China and Yunnan were given in this work. Base on the analysis of iron and steel industry of Yunnan, we choose two steel plants (marked plant A and plant B) as the typical factories to confirm the emission factor of SO2. The emission factor of SO2 was achieved by mass balance method. In steel plant A, the emission factor is 9.684 (kg-SO2/t-steel), after flue gas desulfurization, the factor dropped to 1.476 (kg-SO2/t-steel). It indicates that desulfuration of sinter flue gas is important to reduce SO2 emission. In steel plant B, the emission factor is 5.4(kg-SO2/t-steel) without desulfurization. However, according to Discharge Coefficients of Industrial Pollutants in the First National General Survey of Pollution Sources(Survey Handbook), the SO2 emission factor of plant B is 4.15(kg-SO2/t-steel). We can see the differences exist between Yunnan’s discharges of pollutants with national Survey Handbook. Because the national Survey Handbook represents the national average level and manufacturing technique and raw materials of various factories vary greatly within the country. So it’s necessary to confirm the emission factor for Yunnan province.
