Background
With the rapid development of economic society, the stink/peculiar smell is one of the most intense environmental problems currently complained by the public, and the stink/peculiar smell complaint ratio (11%) of the garbage disposal industry is the first of all domestic industries. The odor pollution management in China starts late, the content of the current mandatory standard is limited, and a standard odor environment influence evaluation guide rule is not established so far; in addition, the wet garbage is easy to rot and stink due to the characteristics of high organic matter content and high water content under the garbage classification policy, the environmental pollution and the human health problem caused by the stink generated by the garbage are more obvious, and the deodorization by adopting the deodorant is an effective way for eliminating the stink pollution. Deodorants are classified into physical deodorants, chemical deodorants, biological deodorants and plant deodorants according to different mechanisms of action, and different deodorants have the characteristics and application ranges.
According to the existing standard 'technical requirement for household garbage deodorizer' (CJ/T516-2017), the method for measuring the removal effect of the deodorizer on hydrogen sulfide, ammonia, methyl mercaptan and methyl sulfide is taken as an example of an experimental method for measuring the removal effect of the deodorizer on the conditions of normal temperature (20 ℃) and normal pressure (1 standard atmospheric pressure)Then, the initial concentration was set to 0.15mg/m3The 15L hydrogen sulfide gas was circulated for 24 hours at a flow rate of 1L/min through a large bubble absorption tube containing 10mL of a biological deodorant (solid biological deodorant dissolved first). And collecting the treated gas, and analyzing the concentration of hydrogen sulfide. The hydrogen sulfide concentration was measured according to GB/T11742.
The test method is simple to operate, but has certain problems; the test method is obviously different from the practical application condition of the deodorant, the common liquid deodorant is sprayed, sprayed and the like to garbage in the using process, and the action principle of the test method is obviously different from that of the test method in the standard. In addition, in the weather with higher temperature, the odor pollution is more serious, and the temperature condition adopted by the method of the standard test is not enough to prove the deodorizing effect of the deodorant in the high-temperature environment.
Therefore, it is very necessary to synthesize the usage of the liquid deodorant, and to obtain the odor pollution dynamics in real time and high efficiency by using the online monitoring device based on the more practical environmental conditions, and to develop the removal efficiency testing device and application method suitable for the liquid deodorant.
