摘　　要：本研究探讨难生物降解的碱法草浆黑液后续好氧生物处理的可能性。试验结果表明:引入部分生活污水、延长水力停留时间和缩短污泥龄可分别起到改善进水水质、延长微生物与难降解物质的接触时间以及提高污泥絮体的活住,增强吸附能力的作用。从而使得活性污泥法对难生物降解的碱法草浆黑液可进行有效的处理。The research investegates the sequent treatability of anaerobically treated alkalineblack liquor from a straw papermaking mill by the process of an activited sludge. Theexperimental results show that the influent characteristics can be improved through in-troducing a small part of municiple wastewater into the black liquor, the adsorptiveproperty of the biological floccu in the reactor can be elevated through shortening thesludge age and treatment efficiency can be enhanced through prolonging the hydrolic re-tention time. By the means of the precautions above, alkaline black liquor can be effec-tively treated by the activited sludge process.
