Gongye shui chuli, 2006 以活性艳红X-3B水溶液为模拟废水，阳离子表面活性剂十六烷基三甲基溴化铵（CTAB）为捕集剂，生成疏水性离子缔合物，正己醇为浮选溶剂，分离富集水中的活性艳红X-3B，光度法测定其含量。该法浮选萃取率>96%，染料质量浓度在1~50mg/L之间，溶剂中离子缔合物的吸光度与水中活性艳红X-3B的浓度，具有很好的线性关系，相关系数为0.999 8，RSD为1.4%。并成功地将该法应用于实际印染废水的测定，加标回收率在90.0%~93.6%之间。

Gongye shui chuli, 2012 采用富集驯化的亚硝酸菌和亚硝酸型反硝化菌对氮肥厂高氨氮废水进行处理。考察了pH的变化特征,研究了进水氨氮负荷对硝化效果的影响。实验结果表明,硝化菌能够耐受高pH废水并能高效脱氮,氨氮去除速率最高达36.07mg/(L.h);连续运行时水力停留时间24h,进水NH3-N负荷在0.387～0.667kg/(m3.d)范围内,稳定运行后硝化出水氨氮去除率大于97%,亚硝化率为80%左右,总氮去除率达90%以上。

Gongye shui chuli, 2019 考察了两组厌氧富集培养系对苄嘧磺隆（BSM）的厌氧降解情况，结果表明，厌氧颗粒污泥稳定培养系的降解效果略好于农药污泥稳定培养系；随着BSM浓度的增加，农药污泥稳定培养系的降解率逐步增加，而厌氧颗粒污泥稳定培养系的降解率则递减；温度的升高有利于提高两组厌氧培养系的降解率。鉴定结果表明：两种稳定培养系中占据优势菌群的门均为Spirochaetes、Bacteroidetes、Synergistetes、Euryarchaeota。
