Description
本創作涉及一種廢水回收設備,特別是涉及一種可提高廢水回收效益的廢水回收設備。This creation relates to a waste water recycling equipment, in particular to a waste water recycling equipment that can improve the efficiency of waste water recycling.
台灣地區近年來對於水資源的需求日益增加,就高科技工業用水而言,目前新竹科學工業園區用水量單日即達12萬5千噸,數量之大非常驚人。但氣候變化導致水資源的供應變得難以預測,解決的方法除了減少用水量,還有就是將工業廢水有效處理並回收再利用。The demand for water resources in Taiwan has been increasing in recent years. As far as high-tech industrial water is concerned, the current water consumption of the Hsinchu Science Industrial Park reaches 125,000 tons in a single day, which is an astonishing amount. However, climate change has made the supply of water resources unpredictable. In addition to reducing water consumption, the solution is to effectively treat and recycle industrial wastewater.
另外,廢水處理也是一門相當重要的環境課題,尤其是針對危害性較高的工業廢水。工業廢水可分為含無機污染物為主的無機廢水與含有機污染物為主的有機廢水兩類;為避免造成環境污染,各類廢水須進行相應的處理以達到規定的水質標準後,才可以被排放或再利用。In addition, wastewater treatment is also a very important environmental issue, especially for industrial wastewater that is more hazardous. Industrial wastewater can be divided into two types: inorganic wastewater containing mainly inorganic pollutants and organic wastewater containing mainly organic pollutants; in order to avoid environmental pollution, various types of wastewater must be treated to meet the prescribed water quality standards. Can be discharged or reused.
固液分離是廢水處理必不可少的一個環節,為提高固液分離效率,常見的做法是添加高分子膠凝劑於廢水中,促使較小的固體物質凝聚成較大且重的固體物質;然而,高分子膠凝劑很容易阻塞過濾元件(如過濾薄膜),導致過濾效果降低、過濾速度變慢,且不能有效去除污染物。Solid-liquid separation is an essential part of wastewater treatment. In order to improve the efficiency of solid-liquid separation, a common method is to add a polymer gelling agent to the wastewater to promote the agglomeration of smaller solids into larger and heavier solids; However, polymer gelling agents can easily block filter elements (such as filter membranes), resulting in reduced filtration efficiency, slower filtration speed, and ineffective removal of pollutants.
因此,如何通過結構設計的改良來提升廢水的可過濾性,從而克服上述的缺陷,已成為該項事業所欲解決的重要課題之一。Therefore, how to improve the filterability of wastewater by improving the structural design to overcome the above-mentioned shortcomings has become one of the important issues to be solved by this business.

[過濾性測試][Filterability test]
[比較例1][Comparative Example 1]
將0.2%的陰性PAM(聚丙烯醯胺,平均分子量為1200萬)水溶液A混合於逆滲透水中,配置成100 ppm的水樣品A;然後,使用孔徑為1微米的濾紙,在-0.48巴(bar)的壓力下過濾500毫升的水樣品A,所需時間為42秒。Mix 0.2% negative PAM (polypropylene amide, with an average molecular weight of 12 million) aqueous solution A in reverse osmosis water to form a 100 ppm water sample A; then, use a filter paper with a pore size of 1 micron at -0.48 bar ( It takes 42 seconds to filter 500 ml of water sample A under the pressure of bar).
[實驗例1][Experimental example 1]
將0.2%的陰性PAM(聚丙烯醯胺,平均分子量為1200萬)水溶液A混合於逆滲透水中,配置成100 ppm的水溶液B;接著,將次氯酸鈉以1000 ppm的含量添加至水溶液B中進行反應15分鐘,完成後得到水樣品B;然後,使用孔徑為1微米的濾紙,在-0.48巴(bar)的壓力下過濾500毫升的水樣品B,所需時間為21秒。A 0.2% negative PAM (polypropylene amide, average molecular weight of 12 million) aqueous solution A was mixed with reverse osmosis water to prepare 100 ppm aqueous solution B; then, sodium hypochlorite was added to aqueous solution B at a content of 1000 ppm to react After 15 minutes, the water sample B is obtained; then, using a filter paper with a pore size of 1 micron, 500 ml of water sample B is filtered under a pressure of -0.48 bar (bar), and the required time is 21 seconds.
[實驗例2][Experimental example 2]
將0.2%的陰性PAM(聚丙烯醯胺,平均分子量為1200萬)水溶液A混合於逆滲透水中,配置成100 ppm的水溶液B;接著,將過硫酸鈉以1000 ppm的含量添加至水溶液B中進行反應15分鐘,完成後得到水樣品C;然後,使用孔徑為1微米的濾紙,在-0.48巴(bar)的壓力下過濾500毫升的水樣品C,所需時間為9秒。A 0.2% negative PAM (polypropylene amide, average molecular weight of 12 million) aqueous solution A was mixed in reverse osmosis water to prepare 100 ppm aqueous solution B; then, sodium persulfate was added to aqueous solution B at a content of 1000 ppm The reaction was carried out for 15 minutes, and after completion, a water sample C was obtained; then, using a filter paper with a pore size of 1 micron, 500 ml of water sample C was filtered under a pressure of -0.48 bar (bar), and the required time was 9 seconds.
由上可知,當水中含有高分子聚合物時,濾紙過濾的速度較慢,增加了濾紙的過濾負擔;相較之下,在過濾之前先加入氯系或硫系氧化性物質,將水中的高分子聚合物解構成小分子,過濾所需的時間可縮減一半以上。It can be seen from the above that when the water contains high molecular polymers, the filtering speed of the filter paper is slower, which increases the filtering burden of the filter paper. In contrast, before filtering, add chlorine or sulfur oxidizing substances to reduce the high Molecular polymers are decomposed into small molecules, and the time required for filtration can be reduced by more than half.
