蔬菜废弃物无害化处理农药残留量变化研究

Study on change of pesticide residue with harmless treatment of vegetable wastes

利用3种微生物菌剂（福贝、大地旺、榕风）对蔬菜废弃物分别进行好氧和厌氧堆沤无害化处理，研究蔬菜废弃物中农药残留量的变化。结果表明，在无害化堆沤过程中好氧发酵提升温度和保温的性能更优于厌氧发酵：好氧发酵中液体质量与渣质量的比值高于厌氧发酵；和对照相比，福贝、大地旺、榕风3个好氧处理下的甲胺磷含量分别比对照降低了68．13％、59．06％、63．16％，乙酰甲胺磷含量分别比对照降低了84．87％、70．42％、77．21％；而厌氧处理降解效果则不明显。

Making use of three kinds of microorganism＇ s ferments （Fubei, Dadiwang and Rongfeng） to have a harmless experiment with aerobic and anaerobic treatment on the vegetable wastes to study of change of pesticide residue. The results showed that temperature was higher with aerobic treatment than that of anaerobic treatment, and the ratio of liquid quality and remnant quality was higher than that of anaerobic treatment. In comparison with contrast treatment, the contents of methamidophos were decreased 68.13%, 59.06% and 63.16%, and the contents of acephate were decreased 84.87%, 70.42%, 77.21% respectively with aerobic treatment of Fubei, Dadiwang and Rongfeng. But the results of anaerobic degradation were not obvious.
