Affiliated technical field
The utility model relates to a kind of animal waste management gas discharging dynamic measurement case, is particularly useful for the spot sampling use of livestock and poultry farm sewage emission flux of gas in storage and processing procedure, belongs to Agricultural Environmental Monitoring technical field.
Background technology
Along with China's animal husbandry large-scale degree improves constantly, cultivation amount rises year by year, and be limited to environmental capacity and the ability of dissolving, livestock and poultry farm ight soil and sewage the like waste cannot be effectively addressed and utilize, the environmental pollution bringing is thus on the rise, according to national Pollutant source investigation communique result demonstration for the first time, the chemical oxygen demand (COD) of livestock and poultry cultivation major pollutants, total nitrogen and total phosphorus discharge account for respectively 41.9% of national discharge capacity, 21.7% and 37.9%, in the storage of the discarded object of animal husbandry simultaneously and processing procedure, be also the main emission sources of harmful gas such as greenhouse gases and ammonia, according to < < People's Republic of China (PRC) climate change national communication > > data demonstration for the second time, the greenhouse gas emission of animal husbandry aquaculture accounts for 6.3% of the whole nation, it is the important greenhouse gas emission source of China, but China's animal husbandry greenhouse gas emissions estimation, especially the waste management process greenhouse Gas Emission factor is calculated the result that substantially comes from foreign literature report, we report relevant for the herding waste management process greenhouse Gas Emission factor and assay method thereof by there be limited evidence currently of, also there is very large uncertainty in emission factor value.
The domestic report of the assay method about farmland ecosystem greenhouse gas emission is more, substantially the static chamber of sampling method, its principle is on testee, to place enclosed sampling case, in certain time interval, gather the gas in closed box, by analyzing different time points gas concentration, change, calculate the emission flux of gas that obtains measured surface, this assay method labour intensity is large, and static chamber is only measured once general every day, the diurnal variation situation that cannot correctly reflect harmful gas, in addition, if use static chamber sampling in feces of livestock and poultry the like waste processing procedure, environmental baseline is more severe, the reliability of measurement result is difficult to be guaranteed.
Utility model content
The purpose of this utility model is the deficiency existing for existing animal waste management gas discharging determination techniques in order to overcome, in the applicable animal waste management process of design, the dynamic sampling of gas discharging monitoring is measured case, utilize the gas discharging speed of this dynamic case in can the mensuration animal waste management process of real-time continuous, the gas discharging being particularly useful in different livestock and poultry farm sewage storages or processing procedure is measured, its operating automation degree is high, simple and efficient.
