在哈尔滨某地建立了室外模拟垃圾填埋场,进行了渗滤液回灌与不回灌的跟踪监测研究。结果表明：回灌能减量87. 05%的渗滤液，明显改善渗滤液水质（显著降低COD、SS、NH4+-N浓度，提高pH值），降低渗滤液处理难度。

从厌氧生物膜反应器、异养一好氧生物膜反应器和硝化生物膜反应器三方面，全面考察了进水底物浓度（So）对生物膜反应器稳态出水水质（So）的影响，发现Se随So的变化呈现半U形曲线。在传统的线性模型基础上，提出了非线性Se-So的模型，该模型能很好地定量描述试验所得数据，并从文献中的数据得到了进一步的验证。所提出的临界进水底物浓度的概念在实际生物膜反应器设计及运行中，具有重要应用意义。

研究了高温/中温两相厌氧消化反应器系统用以同时处理污泥与不同高浓度有机废物时产气及产甲烷的变化特性。结果表明，气体及甲烷主要是在第二段的中温消化反应器内产生。当中温消化反应器的有机负荷VS为1.65～3.10kg/m3d时，稳态条件下的平均产气量为1.958～4.020m3/d，气体中甲烷的平均组成为65%～73%，甲烷的比产率为0.397～O.511m3/kgVS。

Leachate samples were collected from the West New Territory Landfill (WENT), Hong Kong, and characterized in the laboratory. The analytical results confirmed that it has a typical nature ofaged leachate with a low BOD5/COD ratio Of O.22 and a high strength of ammonia-nitrogen around 5G/L. A lab-scale study was conducted to investigate the inhibition of microbial activity of the activated sludge. In the first test. glucose-based synthetic wastewater Was used in two parallel reactors. The experimental results demonstrated that COD removal declined from 95.1 to 79.1% activated sludge. In the first test. glucose-based synthetic wastewater Was used in two parallel reactors. The experimental results demonstrated that COD removal declined from 95.1 to 79.1% activated sludge. In the first test. glucose-based synthetic wastewater Was used in two parallel reactors. The experimental results demonstrated that COD removal declined from 95.1 to 79.1% and the dehydrogenase activity of the sludge decreased from 11.04 to 4.22μg TF/mg mixed Iiquor suspended solids (MLSS), when the ammonia-nitrogen concentration increased from 50mg/L to 800mg/L progressively. The remaining NH3+-N residue in the treated wastewater increased from 0.58mg/L to 649mg/L extensively. In the second test. mixed wastewater samples containing glucose and raw leachate were fed into six parallel biological reactors and operated on batch mode. The experimental results showed COD removal decreased from 97.7 to 78.1% and the dehydrogenase activity decreased from 9.29 to 4.93μg triphenyl formazon (TF)/mg MLSS, respectively. when the ammonia-nitrogen concentration increased within the same range. Mierobial inhibition could alSO be substantiated by a decrease of specific oxygen uptake rate (SOUR) from 68 to 45mg O2/g MLSS. These results suggested leachate containing high-strength ammonia-nitrogen should be pretreated to art acceptable NH4+-N level before it is fed into biological reactors.

传统的活性污泥工艺中加入废弃轮胎颗粒作为生物膜载体形成的复合式生物膜反应器，在颗粒浓度为40g/L时，稳定运行条件下在轮胎颗粒表面可形成约50mg/g的生物膜量，即在传统曝气池的2000～3000mg/L悬浮生长污泥的基础上，可增加2000mg/L的附着生物膜量。此时生物膜的厚度为255Lm，其活性以比耗氧速率（SOUR）表示为40～70mg/g·h。
