To investigate the mechanisms of biohydrogen production by anerobic fermentation of solid organic waste, gas chromatography is used to analysis the biogas and volatile fatty acid in anaerobic bio-reactor. Firstly, the ability of hydrogen production by digested sludge from the West Lake, Enteobacter aerogences, digested sludge from sewage farm, the fluid of methane pool and dejecta have been studied. The rule of the ability of hydrogen production by different bacteria under different control condition. Simultaneity, the importance of the synergistic effect on hydrogen production has been proved.

本文首先选用西湖底的厌氧活性污泥、产气肠杆菌、污水处理厂的淤泥、沼气池发酵液以及猪粪等不同菌群对废弃食物——马铃薯进行厌氧发酵产氢特性实验研究，得到马铃薯在各不同菌群及工况下的发酵产氢能力，同时发现产氢菌间的协同作用很重要，在控制好发酵条件的情况下，产氢菌群发酵通常会好于单一产氢菌的发酵。

Experiments are conducted on the effect of different types and different molecular structures of polymers on HPAM removal existed in solution or sewage. It is found out that only cationic polymer has a better removal effect of HPAM among the non-ion, amphoteric ion and hydrophobical cation polymers, especially the DMDAAC cationic polymer has an optimal result. The removal capacity to HPAM can be further improved by using appropriate molecular weight and cationic capacity and gas floatation technique.

试验研究了不同类别及分子结构的聚合物对溶液或污水中HPAM的去除效果，发现非离子、两性离子、疏水改性阳离子聚合物对HPAM无去除作用，只有阳离子聚合物去除效果较好，其中尤以DMDAAC系列阳离子聚合物效果最优，而适当的分子量和阳离子化度以及气浮技术均可以进一步提高其对HPAM的去除率。

Compared with the composite flocculant of WuHan petrochemical factory, its capability is superior to it: the efficiency of eliminating CODCr and SS are 28.75%and 8.29% respectively higher than those by flocculant of WuHan petrochemical factory, but the cost is46.63% lower; which is also far lower than the current average cost of petrochemical industry wastewater treatment. When dealing with papermaking wastewater, it can fully meet the require that WuHan ChenMing paper industry group put forward: The efficiency of eliminating CODCr higher than 25% based on the chemical cost controlled in 0.5 Yuan/ton sewage so as to better the gas float section. Those studies preparatorily show that this composite flocculant has particular effect and obvious economic、environmental benefit in industrial effluent treatment

其在处理石化废水时性能优于青山石化厂的复合絮凝剂，CODCr和SS的去除率分别提高了28.75%和8.29%，处理成本下降了46.63%；且远低于我国目前平均2.80元/的石化废水处理成本；其在处理造纸废水时，可完全达到武汉晨鸣纸业集团所提出的：药剂成本控制在0.5元/以内、CODCr去除率在25%以上的气浮工段改进要求，初步显现出该复合絮凝剂在工业污水处理中的独特作用及明显的经济与环境效益。

A new technology of plasma-photocatalysis combination was proposed to remove stenchful gas from sewage pump station.It was showed that this combination technology had a quite notable synergistic effect.And the synergistic effect could be enchanced by adjusting the distance between plasma unit and photocatalysis unit and setting some nets between them to eliminate the influence of negative charges produced by plasma unit.

尝试用一种等离子体光催化复合技术净化污水处理泵站臭气，研究表明，该种复合技术具有较显著的协同促进效应，通过改变等离子体发生单元与光催化单元的距离以及在两者之间放置去静电网，可消除等离子体单元产生的负电荷对光催化单元的不利影响，进一步提高其复合效应。
