The pilot perroamace of the alnbined GAC-MF mmlbrane process fordrinking water advanced treatment was described.In the process of GAC adsorption under the conditions of 20 mill HRT and 6m/h filtration rate, the rexnoval efficiencies of UV254% and trichioromethane could reach 40%and 50% respectively and the uv254 and trichloromethane in system effluent was less than 0.015 cm-1and 5ug/L respectively. In the post MF mcmbrane process, MF membrane effectively retained the particles and bacteria in raw water. The effluent turbidity was less than 0.2 NTU and no bacteria welag detected at all in permeate. A computer-controlled system was employed to control this system. The membrane operating par, ureters of backwash interval, duration and flux welag studied. The backwash interval of 10-min, 20-min and 60-min was researched respectively, and the variation of trans-membrane pressure was also analyzed.Consequently short backwash intervalwas recommended underthe samewater consume.

进行了以不同钙含量的粉煤灰为原料合成的3种沸石对污水中磷去除的试验，探讨了表面交换性阳离子种类、投加量以及磷浓度对除磷的影响。结果表明：最佳投加量为8g/L，磷去除率可达到70% 1，7，上。合成沸石除磷能力均高于粉煤灰，钙饱和处理又可明显进一步提高粉煤灰合成沸石的除磷效果。粉煤灰合成沸石钙含量越高，对磷的去除率越高。因此，采用高钙粉煤灰为原料合成沸石并进行钙饱和处理，可以获得除磷能力强的合成沸石材料。

利用工业废弃物粉煤灰制备活性粉煤灰除磷剂AFA，将AFA与传统的砂滤工艺相结合，用于二级出水中磷的去除。结果表明：当AFA投加量为100mg/L时，可确保滤后水中磷质量浓度<1mg/L，达到GB 18918-2002中一级标准。投药后预沉淀1min可显著延缓水头损失的增加。在无预沉淀、滤速32 m/h的工艺条件下滤床则极易堵塞。水头损失分析显示，过滤中大部分携磷微粒被截留于厚度为160mm的滤床上层。

The aim of the research was to obtain both an excellent effluent for reuse and a reduced sludge production simultaneously by a combinaittion process of anaerobic phase and Membrane biroeactor (MBR)technology in treating domestic wastewater. During the experimental period of three months, excellent removals for COD, NH3-H,TN were obtained, and mean removals were 91.87%, 96.13%, and 69.23%, respectively. Whreas, at first 20 days, the removal for TP was only abut 15.87%. In The following days, about 30% of raw water was introduced into the anaerobic reactor to supply organics for denitrification and release of polyphosphate, then a significant improvement for TP removal was observed, and mean removal of TP increased to 76.35%. During the operational period, it was investigated that the permeate could meet the requirements of several water criteria for reuse except free chlorine, and a mean excess sludge yield coefficient of 0.137g MLSS/g COD was obtained. Therefore, the predicted goals of permeate for reuse and excess slu7dge reduction could be both achieved after dosing a certain quantity of disinfectant into the permeate.

以粉煤灰为原料，采用水热合成法制备沸石，造粒后合成沸石填充至滤柱中，研究了不同运行条件下合成沸石对污水中磷的净化与回收效果。结果表明：合成沸石对模拟污水和城市生活污水经二级生化处理后的排放水中磷的去除能力相近，且在磷含量低的情况下后者高于前者；与造粒前相比，造粒后的合成沸石仍具有良好的固磷能力，水力负荷明显影响滤柱中磷的去除效果，其在177.9u（n12-h）以下时，磷的去除效果较好。此外，进水pH也明显影响合成沸石的除磷效果，当进水pH调至酸性或碱性范围时，合成沸石的除磷能力显著提高，该滤柱能够长期有效地净化与回收污水中的磷，达到饱和时合成沸石的w（磷）达20.04g/kg（以磷元素计），可实际应用于农田改良。
