Added sewage deodorizer principle is deodorant under the action of high-energy rays and a variety of harmful, odorous substances such as hydrogen sulfide, methane, methyl mercaptan, ammonia and other volatile organic compounds (VOCs) and other malodorant gases quickly polymerization, substitution, replacement, adsorption and other chemical reactions, so that it becomes non-toxic, tasteless molecules. Sewage deodorant itself is generally neutral, non-toxic, non-flammable, non-corrosive, no secondary pollution, no explosive hazard, not flammable dangerous goods, no oxidant hazard, not corrosive, not toxic.
Process deodorization is to the process of sewage treatment with deodorant function of the process, common ozone (oxidation) chemical absorption plus adsorption process deodorization method. Principle is as follows: ozone is a potent neutral chemical absorption oxidant, and no second pollution, oxidation and reduction to oxygen (02) and water (H2O) decomposition of the gas, low volatility, cracking malodorous gases so that the free state of the pollutant molecules and ozone oxidation into small molecules of harmless or low-harm compounds, such as CO2, H2O and so on. Chemical absorption part of the application of the concentration of 1 to 10% (mass) ozone gas, if the high temperature can be appropriate to add water to improve the performance of ozone oxidation. Through the ozone oxidation ammonia removal rate of 95%, hydrogen sulfide removal rate of 60%. After chemical absorption (oxidation) of the odor waste gas ammonia, hydrogen sulfide a large number of reductions, at this time the odor waste gas is a low concentration of hydrogen sulfide and organic components, through a large amount of information collection and analysis, in order to further reduce the low concentration of malodorous odors, but also can be used to adsorption is an effective way to further deal with the malodorous waste gas. Only need to set up the corresponding exhaust pipe and exhaust power, so that the malodorous gas through the equipment for deodorization decomposition and purification, without adding any substances to participate in the chemical reaction. Research has proved that by adding 4.8ppm ozone, the odor degree of 50 degrees can become odorless, and by adding 2ppm ozone in a small experimental device, the odor degree can be reduced from 20 to 0. There are experiments to prove that in removing the odor below 25 degrees in water, the ozone injection rate is 0.1-1.5ppm. The ability to deal with malodorous gases has a lot to do with the composition and concentration of malodorous gases, and the required capacity of the equipment depends on the average value of the concentration of malodorous gases. Malodorous gas concentration of the average value of the settings and malodorous out of the air volume calculation.
The principle of cesspool covering membrane structure and cesspool cover is simple and direct, one investment, continuous benefit, mainly sealing the malodorous gas and preventing the odor from spreading to the atmosphere near the cesspool.
