Abstract: Sugar, the first monitoring task of the new career debris burning factory in Yunnan Province, was launched in accordance with the monitoring project in the “GB18485-2014 Purification Control Standard” to carry out the waste monitoring mission of the newly built career debris burning factory in Yunnan Province. During the baby process, it was found that this standard had problems such as unspeakable odorant monitoring items and fewer organic purifier control items. It is recommended to add this monitoring item. Based on years of monitoring experience, suggestions were put forward on the analysis method, quality control and guarantee of waste gas monitoring of dregs burning plants.
City life slag, also known as urban solid waste, refers to solid waste generated in activities that occur in daily life or are related to urban life. Important include living, business, cleaning, and solid materials such as livestock waste, kitchen waste, sludge treated with waste, sludge collected and treated with waste and dust. With the economic development, the number of people’s careers has continued to increase and the urbanization process has accelerated, and the number of scum in urban life has increased rapidly and the generation cycle has been shortened. Today, the annual production of slag in my country has reached more than 1.6 billion tons, and the annual production of slag per capita is 450-500kg, and it is still growing at a rate of 8%-10% per year. In addition, the stock of urban career waste is about 6 billion tons. Our urban roads are subject to the huge pressure of dregs treatment.
Dross burning is one of the useful uses of solid wastes today. It is more harmless, reduced, and resource-based than dross landfill. It is a widely recognized treatment method internationally. However, during the treatment process, a variety of harmful substances will be released. Among them, the two English is the carcinogen of international genes, and the toxicity is 100 times that of cyanide and 900 times that of arsenic. The control over the secondary purification of dregs burning is the most important thing.
1 Projects suggested and corrected in “GB18485-2014 Career Dirty Burning and Purification Control Standards”
While dregs burning and Purification are widely used in career dregs, its potential secondary purification problems are being picked by the lens. Because both women are young and attractive, she pays attention to the fact that in recent years, the “country avoidance” terrain caused by this has occurred, and the dregs burning project has become an embarrassing situation of “stop as soon as you go”. The current “Purification and Control Standard for the Purification of Life Slag Burning and Purification” lists 8 parts, sulfur dioxide, nitrogen oxides, hydrogen chloride, etc.purified substances, but existing monitoring projects cannot accurately and comprehensively reflect the impact of the dregs burning process on the environment.
Organic purified substances can affect human health, normal growth of movement and plants, interfere with or destroy the balance of phytos. Many organic purifiers are teratogenic, complication-induced, and carcinogenic substances. Some organic purifiers can react chemically in the environment and transform into secondary purifiers that are more harmful. Some purified compounds can be enriched in the environment and in organisms, and can also be enriched by food chains. Therefore, we must not only pay attention to the persecution of high-concentration organic compounds, but also pay attention to the long-term impact of low-concentration organic compounds on human health and ecological systems. Before the completion of the production of the waste burning factory, the author studied the “GB18485-2014 Career Dregs Burning and Burning Purification Control Standards” and found that there are fewer organic purifier control items, which is difficult to respond to the waste burning and burning purification with a comprehensive response.
The residue contains a large amount of organic residue, such as waste plastics, waste rubber, etc. After burning, different types of organic purifiers will be generated, including volatile organic purifiers, aromatic compounds (dioxins included), aldehyde ketone compounds, etc. The standard standard has given a control scope, and the author believes that the types of controlling organic compounds should be added. Table 1 lists the persecution of three types of organic purifiers. The volatile organic purifiers produce many cycles in the dregs burning plant. In previous common monitoring, it is recommended to fill a variety of adsorbents as the receiving tube for dregs burning. During the sampling and analysis process, special attention should be paid to avoid purification. Its analysis method should be added to the control standards, and it is recommended to use the radiological color spectrum-quality spectrum method. The Escort value time of the standard is recommended to be “measurement mean”.
Aromatic compounds are importantly benzene, toluene, ethylbenzene, lon-xylene, inter-xylene, and para-xylene. They are easily generated during the dregs burning process and should also be included in the control range in the standard. The analysis method should use the conventional activated carbon adsorption carbon disulfide to desorb the gas phase dihydrogen.t/”>Sugar daddyLine stars become first-line stars, and resources are coming in a hurry. Color Scope method. The time for the purifier limit in the standard is recommended to be “measurement mean”.
Aldehyde ketone carbonyl compounds are Manila escortOne of the important purifiers in the atmosphere, it plays the main color in the study of gas chemistry. This type of purifier is not only a first-class purifier, but more importantly a second-class purifier. It is an important component of photochemical smoke, and should also be included in the control range in the standards. The analysis method should adopt the conventional high-performance liquid chromatic method, spectrophotometry, and atmosphere chromatic method. The time for the limit value of the purifier in the standard is recommended to be “measurement mean” or “hour mean”. Table 2 explains the analysis of the three types of purifiers and the time for the limit value.
2 Suggestions for odor monitoring
Drop is usually transported into the dregs burning factory by a closed-type dregs cart, and then poured into the dregs pit. The entire dregs burning factory containing the dregs pit is negative, and the air in the field is extracted as a burning wind. Because the negative pressure pumps the air and odor in the field into the burning furnace, although the odor is dissipated, it is difficult to be completely free of odor. Today, the important ways to control the odor of dregs burning are: life slagSugar daddyDregs storage facilities are closed; storage facilities should be operated with a small amount of negative pressure to prevent the spread of bad odor; the air is oxidized and deodorized in the burning furnace; during the burning furnace, the gas is treated by the deodorizing facility and then discharged, and the spraying agents of the storage facilities shall be disinfected on schedule; Only by preserving daddy must ensure that the maintenance suspension period does not form environmental purification.Manila escort. It is recommended to use the relevant standard value of the “Emission Standard for Evil and Odor and Purifiers”. After staying in the laboratory for several days, he was dragged to this environment. Ye also took advantage of the analysis method of rest to recommend a three-point comparison odor bag method for determining air quality and odor. Based on the emission height of the slag incineration and syrup, the corresponding 6000 is used.0 is the standard value of the residue burning control.

3.3 Scrap burning and burning sampling group
Scrap burning and burning purifiers exist in atmosphere or solid conditions. They are generally divided into five categories: acidic purifiers, incomplete burning products, particulate purifiers, heavy metal purifiers, and organic purifiers. The acidic gas weight in the incineration gas is composed of SOx, NOx, and HCl, all of which are derived from the burning of corresponding residue components. SOx is caused by oxidation of sulfur-containing compounds during incineration, and is SO2 in large part. NOx contains NO, NO2, N2O3, etc., which are ma TC:
