Based on the results of water quality (physical and chemical factors: water temperature, salinity, pH, DO, DIN, PO4-P, COD, and biomarker-indicated: total bacteria and Coliforms) determining from the 4 pools and infall, outfall of the Xishan Island aquaculture pond, the variation characteristics of water quality in infall, outfall of pond and its reasons were analysised and discussed.

结果表明：养殖场和进、排口水体温度、盐度变化不明显，pH下降与养殖周期有关；营养盐含量增加，在不同养殖种类、养殖周期和养殖饲料系数变化不同；受消毒杀菌等措施影响下细菌总数与大肠杆菌总数明显减小，而养殖周期长的池塘，细菌总数仍增加，大肠杆菌总数减少幅度变小。

This article mainly explains the safety principium of infectant factors in waste water vented by the paper making industry in China. Through the study on the experiment in open country and indoors with soil pole, indicating that it is a complicated process of biochemical degradation to form a layer, which has a biochemical capability to process COD degradation in polluted water from paper making industry.

综述我国造纸业污水中的污染因子危及地下水水质安全的机理，通过对野外试验和室内土柱试验的过程及结果进行分析研究，表明在包气带中形成一个以生物化学作用为主的生化层在造纸污水中COD降解是一个复杂的生物化学降解过程；生化层在天然状态下形成，由生物氧化带和生物氧化还原带形成，其形成过程具有明显的阶段性；只有当生物氧化还原带形成后，生化层才发育成熟，具备对COD降解的生化能力；生化层空间分布，仅局限在污水池、渠底部包气带中有垂向渗流的部分。

But in reality, wastewater treatment process, the gas production also affected by COD in the influent concentration effects.

但在实际废水的处理过程中，产气量还受进水中的COD浓度的影响。
