(一)本發明藉由輕質過濾砂及反向污水處理的構造與污水過濾程序的設計，使該輕質過濾砂的比重小於水，能夠上浮聚集在污水過濾槽頂部，用以過濾往上流動的污水；而污水中的固態雜質因比重大於水能與該輕質過濾砂分離，大部分並自行往下沉澱於污水過濾槽底部，藉此達到長時間維持過濾效率、減少過濾材保養維護次數的功效。

結果 (英文) 1:

(A) of the present invention, by light sand filter design and construction and water filters reverse wastewater treatment, so that the light water is less than the specific gravity of the sand filter can accumulate at the top floating water filtration tank for filtering up water flow; and sewage by solid contaminants heavier than water is separated from the light sand filtration, and most of the water itself down precipitates at the bottom of the filter tank, thereby maintaining the filtration efficiency for a long time to reach, reducing the filter material maintenance efficacy times.

結果 (英文) 2:

(1) By means of the construction of light filter sand and reverse sewage treatment and the design of the sewage filtration procedure, the proportion of the light filter sand is less than water, and can be floated on top of the sewage filter tank to filter the sewage flowing up, and the solid impurities in the sewage because the proportion is greater than the water can be separated from the light filter sand, Most of them settle down at the bottom of the sewage filter tank, thus achieving the effect of maintaining filtration efficiency for a long time and reducing the number of maintenance and maintenance of filter materials.

結果 (英文) 3:

(1) by the structure of light filter sand and reverse sewage treatment and the design of sewage filtration program, the proportion of light filter sand is smaller than that of water, and the light filter sand can float upward and gather on the top of sewage filtration tank to filter the sewage flowing upward; and the solid impurities in sewage can be separated from the light filter sand because the proportion of solid impurities in sewage is larger than that of water, and most of them settle down in sewage filtration tank by themselves At the bottom, it can maintain the filtering efficiency for a long time and reduce the maintenance times of filter materials.
