商人都是這樣..因為他沒賺到 在很久以前 板橋地區紡織廠 下雨天也是直接排出來... 紅的.. 橙色 每當火車還沒到橋..就聞到臭味 (普通車可是沒空調) 賺了錢有回饋社會嗎 ? |

你在搞笑是吧，我問最終廢棄物如何處理，沒人問你過程如何？ 你拉了一坨屎在泳池裡，有很多方法都能把屎給撈出來， 可是屎還是在那裏，那坨屎你要如何處理？ 另外離子交換跟半透膜…… 此文章於 2011-04-23 05:22 PM 被 sibaken 編輯. |

As the Reverse Osmosis(RO)technology has been used in the fields of water-treatment, the scale of RO elements’cleaning market is increasing obviously. General chemical cleaning can clean out the most of pollutant, and prolong the life of elements to 3 years or more years, but that can’t recover the performance of membrane absolutely. Many elements must be out of commission in 3-5 years. The recovering of membrane’s performance and reuse of disused elements’are regarded as a problem by public in recent years. The study on evaluation of membrane fouling is few. The systemic study on cleaning of fouling, recovering and reuse of disused RO elements are reported scarcely any. Based on above problems, the way of evaluation of RO elements is introduced. The general ways of RO elements’cleaning and factors of impacting the effects of chemical cleaning are studied by experiments. The recovering of performance of disused RO elements and reuse are studied particularly. Accorded to the RO designing software, the way of evaluation of RO elements’fouling under the same testing conditions is introduced. For the elements retaining a little capability of removing salt and transporting water, the author discussed the cleaning effects under different conditions, referring to kinds and concentration of chemical, time of reacting, pH, temperature and so on. The feasibility of reuse of disused RO elements and recovering their performance is studied particularly. For the elements losing capability of removing salt and transporting water, the author introduced recovering element performance by tearing down, chemical surface-treating, second scrolling. The experiments indicated that disused RO elements gained well capability of transport water, but the performance of removing salt declined partly. Moreover, the regenerated elements can filtrate most of suspended solids, colloids, and organics those molecular weight are over 200 in water. The elements’configuration by second scrolling is the same as the early elements. These characteristic make it possible to reuse regenerate elements in the fields of desalting, pretreatment of RO projects for wastewater recycle, material concentration and so on. As the result of cost-benefit analysis, the regenerate elements reused in above fields can reduce cost of RO projects partly.

哇~中英文、產業升級、環境衝擊、貧道與道友的糾葛、新加坡再創工程壯舉、甚至還有肉販的心聲，

論國內企業的管理，奇美實業算是比較好的。
但是許先生那一番話聽過就算了，要外移的一個重要原因就是大陸和中南半島幾個國家已經成為塑化品需求大宗，不把上游原料的工廠設在製造的大本營才是白癡。 |

真的是很佩服你，能不能用三句話講出來， 最後撈出來的屎你怎麼處理， 燒掉，重新RECYCLE，稀釋排放？ |
