实验结果显示：在填理垃圾量和渗滤液循环量相同的条件下，经过60d的厌氧渗滤液循环，对比垃圾柱的出水COD浓度为1333.2mg/L，而破碎垃圾柱和压实垃圾柱出水的COD浓度分别为582.4mg/L和2112.4mg/L。

The sulfate-reducing-bacteria were immobilized in polyvinyl alcohol to treat wastewater containing zinc. The effects of different crosslinking reagents on the conglobation, cohered efficiency of the carbon source, reduction ratio of sulfate, removal ratio of Zn, and COD of drainage were considered.

摘 要：以聚乙烯醇为包埋介质，对硫酸盐还原菌进行固定化处理；以含锌废水为处理对象，考察不同交联剂对成球性能影响、营养源内聚效果、硫酸盐还原效果、锌离子去除率和出水COD等因素。

But, because of the complexity of the dye molecule, there has been short of detailed comprehension in its photocatalytic degradation process. The key problem is difficult to detect the intermediates clearly. In this paper, the photocatalytic degradation of azo dye Congo red in water solution was investigated on UV irradiating TiO2 in the homemade reactor. The optimization conditions were determined and then the rate of decolorization, COD decrease, yield of CO2 and varies pH of aqueous solution during illumination were detected; The varies of the possible intermediates during degradation process were monitored with UV-VIS spectrum and HPLC. The possible mechanism of Congo red photocatalytic degradation is discussed combined with the data of MS.

本文选择有代表性的常见偶氮染料—刚果红作为研究对象，以自制TiO2为催化剂和小功率紫外灯为光源，在自制光反应器上确定了光催化降解的优化条件，并在这个优化条件下测定了降解过程中的脱色率、COD去除率和CO2生成量；利用数显酸度计、紫外可见分光光度计和高效液相色谱仪跟踪测定了降解过程中的可能产物，并结合质谱的数据初步探讨了刚果红的可能降解机制。

Therefore, we studied two levels of biochemistry processing water leakage again in turn after the ozone tower, the ceramic filter the tower and the activated charcoal tower union depth processing craft again, this place principle craft its COD remove rate was 72.8%, anionic surfactant medicinal preparation remove rate was 90.9%, petroleum class remove rate was 78.8%, the total phosphorus and total nitrogen remove rate separately was 73.8% and 82.7%, the final water leakage might directly use in the city afforests, flushes the restroom, eliminates and washes the vehicle and so on, had the good environment, the society and the economic efficiency.

为此，我们又研究了二级生化处理出水再依次经过臭氧塔、陶滤塔与活性炭塔的联合深度处理工艺，该处理工艺其COD去除率为72.8%，阴离子表面活性剂去除率为90.9%，石油类的去除率为78.8%，总磷和总氮的去除率分别为73.8%和82.7%，最后出水可直接用于城市绿化、冲厕、扫除及洗车等，具有良好的环境、社会和经济效益。
