The concentrations of CODcr and NH4+ vary from low to high, then from high to low in the process of refuse leaching, that is to say that there are three phases which are aerobian decomposition, facultative aerobian and anaerobian decomposition;(3)The time of landfill reaching to stabilize under the condition of filtration, for landfill of Jinqianpu, is at least 86 years if CODcr is regarded as a index; but is about 98 years when NH4+ as an index;(4)The column leaching experiment simulated is carried on interactivity between leachate and different lithologic characters, water-bearing media of different thickness. Some parameters can be determined by calculation, such as, the retained factor and hydro-chemical transportation rate of pollutants in suspended media, which quantitatively analyse the suspended soil capability of components purification and the pollution scope of water bearing media.

垃圾淋滤过程中和经历了一个由低到高、再由高到低的过程，即垃圾填埋过程中经历了好氧分解、兼性好氧分解及完全厌氧分解等三个阶段；（3）垃圾组分在淋滤条件下分解达到稳定的时间，对于金钱堡垃圾填埋场，若以作为考核指标，填埋场达到稳定化时间至少需要86年；若以作为考核指标，则填埋场达到稳定化至少需98年的时间；（4）对垃圾浸泡液与不同岩性、不同厚度含水层介质之间的作用进行了土柱淋滤模拟试验，通过计算污染质在包气带介质中运移的阻滞因子和水化学迁移率等参数，定量地描述了包气带土层对污染质的净化能力和污染范围。

It was emphasized that GB3838-2002 not only need to pay attention to the full treatment of wastewater and rainwater but also the proper disposal of treated wastewater which meet the national discharge standard GB18918-2002 but still contain significant amount of pollutants if compare with the national surface water quality standard GB3838-2002. To the brooky region of Jiang-Zhe Plain, the discharged pollutant loads still significantly exceed the environmental capacity of the receiving waters even if all treated wastewater meet the first grade B limits of GB18918-2002, and the water pollution problem still cannot be really eliminated.

通过比较分析，我国现行的城镇污水处理厂污染物排放标准GB18918-2002和地面水水质标准GB3838-2002，明确提出，相对于这一区域的地面水环境质量而言，不但雨污水必须得到充分有效的净化处理，达标排放的污水中也仍然含有总量不容忽视的污染物质；对于江浙平原河网地区，即使全部城市污水都达到GB18918-2002中一级B的要求，排放的污染物负荷仍然会明显超过受纳水体的环境容量，水污染问题仍然难以真正消除；达标处理水的处置与利用问题值得特别的关注与探讨。

Personally, even with the May 27th pole shift date come and gone, we are continuing preparations - we have added to our freeze dried food and seed stores and we now have multiple systems to collect water, store water, purify water and heat water and are currently working on the bicycle powered air infiltration system to our shelter as well as have added two 4 x 10 solar panels to the shelter roof to produce water, have purchased two 120 photovotaic panels to make electricity with along with a charge controller and deep cycle RV batteries, and now have a bicycle generator ( a really nice unit found at www.windstreampower.com ) to produce electricity should there be no sun along with two 12VDC to 120V invertors for running small appliances and even the washing machine.

就个人而言，即使2003年5月27日---极移的日期来了又溜走，我们还是在继续做准备----我们已经增加了冷冻干食品和种子的储存量，并且有了收集，存储，净化和加热水的复合系统设备。我们现在正致力于为避难所建造由自行车供电的空气渗透系统，还在避难所的屋顶上加入了2个4x10的太阳控电板，以便制造出水源。我们也购买了两个120光生电池板和两个充电控制器，以及可多次循环使用的 RV 电池，用于供电。现在我们已有了自行车发电机（在 www.windstreampower.com 上发现的一个很不错的东西），没有阳光的时候用于发电。

After analyzing the hydrodynamic condition and the variations of the water environment factors over the past 20 years(1983-2003) of Tieshangang bay ,we tried to find out the relationship between the self-purifying ability and the environment factors of Tieshangang Bay.

通过对铁山港湾水动力条件及20a(1983~2003年)来水环境因子变化状况的分析，探讨了该湾水体自净能力及其与环境因子之间的关系，结果表明：该湾具有较强的水体自净能力，但其物理净化能力是以潮流的水动力作用影响为主，迳流影响较小，与北海湾和钦州湾有明显差别；其化学净化能力主要体现在溶解氧的含量水平、有机污染物的氧化分解能力、营养盐的形态转化及消减程度上；其生物净化能力则体现在微生物及浮游动植物对有机物的直接降解及间接贡献上，具有贫营养区的水体自净特点。
