油污土壤就地生物治理通过翻耕方式向土壤中供氧。翻耕频率对治理效果有一定影响。翻耕供氧充分 ,油污土壤中细菌大量繁殖 ,土壤呼吸作用强 ,油污去除率大。在实验室研究中 ,翻耕以 1次 /3天为宜 ;在实际治理中 ,翻耕以 1次 /7天或 1次 /1 5天为宜。
Oily soil In-situ biological control Plows oxygen into the soil through tillage. Tilling frequency has a certain impact on the treatment effect. Plowing sufficient oxygen, bacteria in oil soils multiply, strong soil respiration, oil removal rate. In laboratory studies, tillage to 1/3 days is appropriate; in the actual governance, tillage to 1/7 days or 1/15 days is appropriate.
