生物降解度

合成洗涤剂生物降解度试验方法

Laundry degradation testing method for biodegradability of synthetic detergent

同时，MAZ添加剂在水中溶解度低，生物降解度高，不含任何金属等有害物质，具有良好的环境安全性。

Also MAZ additives are environmental safe products thanks to their low solubility in water , higher bio-degradability and free from any metallic substance .

半连续活性污泥法测定表面活性剂的好氧生物降解度

Aerobic biodegradation of surfactants using semi-continuous active sludge method

建立和完善了表面活性剂生物降解度的测定方法，包括活性污泥的制备、培养、驯化和降解等试验过程。

Establishing and perfecting the method of determining degradation extent , including the process of preparation of actived sludge , cultivation , domestication and degradation of surfactant .

同时，根据地化资料研究了原油的成因，认为二叠系稠油是生物降解和成熟度较低共同作用的结果，石炭系的稀油存在轻组分散失现象；

Meanwhile , the causes of oil formation are investigated based on datum of Reservior Geochemistry : Viscous crude of Permian is the result of biodegradation and low maturity working together , and that lighter hydrocarbon constituent of Carboniferous oil is missing .
