Abstract
[ Objective ] The study aimed to discuss the influencing factors and effective measures for the biological degradation of chemicalindustrial waste residue with the soil microbial. [ Method ] In testing area the soil samples were taken from the surface soil in 20cm with quartering method and the burning weightlessness of unit quality was detected resp., and then the different waste residue was applied in the each experimental plot and the their burning weightlessness were determined after taking the samples in the interval of 5 d, thus the degradation data of organic waste residue in each block of soil was acquired. [ Result ] The biological degradation of organic waste residue with the soil microbial was effected by the waste residue property and surface area, soil oxygenation content, soil pH, soil moisture content and soil temperatures. The aerobic degradation of organic matter was much faster and fuller than the anaerobic degradation. As the soil pH affected the microbial activities, it should be maintained at 7～9. Controlling the soil moisture content of 50％～60％ was the best condition of microbial activity. When the soil temperature was below zero, the biological degradation stopped basically. [ Conclusion ] In the actual application of industrially processing the organic waste residue, the some soil texture and some kinds of wasted residue still needed for further research so as to control the biodegradation rate and degree and its management measures. texture.关键词
