摘要

活性污泥法為目前世界上的城市污水最常用的處理方式，此法具有諸多優點，然而在處理過程中，往往會因微生物增殖而產出大量的廢棄活性污泥（waste activated sludge，WAS），這些廢棄污泥，濃縮性差，且污泥的處理費用高昂，以常規的污泥處理和處置需要花費大量的人力和物力，若處理不當，很容易造成二次環境污染，其中的有毒物質會直接影響人體健康和安全。因此在本論文研究中，藉由從環境中篩選優勢菌種，並將其組成複合優勢菌，開發具安全、無毒、無害及不破壞生態環境特色之污泥減量生物製劑，再投加到污水處理系統中進行處理，研究水中COD、SCOD、SS、VSS等，探討生物製劑對污泥減量之處理效果有效減少污泥量，同時探討經處理後之數值變化，經實驗結果證實，在第5天時污泥減量率可達34.3 %，能夠有效降低污泥量。

Activated sludge process method is currently the world's most popular urban sewage treatment, this method has many advantages, but in the process, often due to microbial growth and the output of a large number of waste activated sludge (waste activated sludge, WAS) these waste sludge, poor concentration, and the high cost of sludge treatment to conventional sludge treatment and disposal need to spend a lot of manpower and material resources, if not handled properly, it is likely to cause secondary environmental pollution, including toxic substances will a direct impact on human health and safety. Therefore, in this paper, study, screened by the dominant species from the environment and the composition of complex dominant bacteria to develop a safe, non-toxic, harmless and does not damage the ecological characteristics of the sludge of biological agents, and then vote added to the sewage processing system for processing, research water COD, SCOD, SS, VSS, etc., of biological agents for sludge treatment effect reduce the amount of sludge, while the value of changes after treatment, the results confirmed that in the first 5 days sludge reduction rate of 34.3%, can effectively reduce the amount of sludge.
