In connection with the uncertainty problem of pollutants diffusing in the atmosphere of Wuan city, we monitor and put forward a new conception about air ground pollution belt, and get two-dimensional finite difference equation of air pollution. Meanwhile dispersion coefficient and wind speed are considered as grey parameters. One grey numerical quality model of air pollution is built according to...
Hydrogen sulfide is a kind of toxic and harmful gas and will pollute atmosphere environment if exhaust it directly. There are a lot of desulfurization methods so far, and the desulfurization by activated carbon is a kind of better method. The desulfurization capacity of activated carbon fiber(ACF), granular activated carbon(GAC)and power activated carbon(PAC) are studied in this paper. The results...
In this article, a series of ecological environment problems of Liaocheng city, such as the exploitation of groundwater, water-pollution, air pollution, noise, land salinization, and forest cover rate are discussed in details. Taking these problems into consideration, the author puts forward some feasible strategies and suggestions which can direct the development of eco-environment in a right way...
Qingdao Licang District is a traditional industrial area. For the existing environmental conditions in Licang District, various pollution indicators through analysis of data on the local atmospheric pollution are summarized in this paper. We have gathered the composition of major pollutants causing pollution in Licang District. So we get the main sticking point of the problem affecting the quality...
Hydrogen sulfide is a kind of toxic and harmful gas. If discharging it directly or discharging it after it is burnt into sulfur dioxide, it may cause terrible pollution to atmosphere. Wet Desulphurization is a common method, but there is minor products in the mother liquor of desulphurization. This paper adopts the method of simulating mother liquor of desulphurization, by adding into minor products...
Because of the uncertainty problem of pollutants diffusing in the atmosphere of Handan city, we monitor and put forward a new conception about air ground pollution belt, and get two-dimensional finite difference equation of air pollution. Meanwhile dispersion coefficient and wind speed are considered as grey parameters. One grey numerical quality model of air pollution is built according to grey theory...
Sulfur dioxide is a kind of toxic and harmful gas, and will pollute atmosphere environment if exhausted directly. There are a lot of desulfurization methods so far. The desulfurization efficiency including many kinds of fly ash containing bag dust remover, electric dust remover and wet dust remover mixed with calcium hydroxide in the same mixture ratio, same hydrogen temperature and same hydrogen...
Sulfur dioxide is a kind of poisonous and harmful gas, and will pollute atmosphere environment if exhaust it directly. There are a lot of treatment methods so far. In this paper, it summarizes the main ideas and main characteristics, as well as the necessity for carrying out the discharge right which is used to solve the sulfur dioxide pollution and proposes the design logos of SO2 pollution discharge...
By mean of monitoring SO2 and NOx, we put forward a new conception about air ground pollution belt, and get two-dimensional finite difference equation of air pollution. Meanwhile dispersion coefficient and wind speed are considered as gray parameters. One gray numerical quality model of air pollution is built according to gray theory and applies to the air pollution diffusing system of Handan city,...
Hydrogen sulfide is a kind of toxic and harmful gas and will be harmful to respiratory system of people if exhaust it directly. There are a lot of desulfurization methods so far, and the desulfurization by activated carbon is a kind of better method. But the waste activated carbon needs regenerate. The desulfurization efficiency of regenerated waste carbon is studied in this paper. The results indicate...
Sulfur dioxide is a kind of poisonous and harmful gas, and will pollute atmosphere environment if exhaust it directly. There are a lot of desulfurization methods so far. The desulfurization efficiency of dry-desulfurization agent that is made under the same proportion, hydration temperature and hydration time is studied in this paper. The results indicate that the desulfurization efficiency of the...
