for removal of organic polluters.

因此,在利用次氯酸钠净化和在得到沉淀中磷脂进行色谱分析的基础上，得出结论，沉淀中的脂肪含量几乎等于污水中的脂肪含量。这证实了该技术的有效性除去有机污染物。 Conclusions

We can see that, as of the present day, the existing technologies for wastewater purification enable us to remove any polluter out of them. However, thereby it is also crucially important to consider the cost of such purification, especially taking into account the present condition of national economy. That is why we have chosen the subject purification method not only with regard to the efficiency of wastewater purification with which it is characterised but also with regard to its cheapness. If we analyse the data received as a result of the experiment, we can see that polluters are mostly concentrated in the deposit which was received as a result of water neutralisation and water clarification. This deposition can subsequently be recycled and used as an organic and mineral fertiliser containing N, P, K, and Na. The clarified water then goes to the next stage of additional purifi cation. The details stated above testify to the fact that the presented method allows reaching a high degree of wastewater purification, being effective and low-cost.

结论

我们可以看出，现在的污水净化技术能使我们去除其中任何的污染物。然而，绝对重要的是这样净化的成本，特别是考虑到国民经济的现状。这就是为什么我们选择物质净化方法不仅要考虑污水净化效率,还要考虑它的价格。如果我们分析得到的实验数据，我们可以看到污染物大多集中在中和、净化所产生的沉淀物中。这些沉淀物随后

作为富含氮、磷、钾、纳的有机矿物肥料被循环利用。澄清的水接着进行下一个阶段的净化。上述事实证明提出的方法可以实现污水高度净化，具有高效、低成本的特征。
