本研究主要係因工業區的聯合污水處理廠由於處理水量大,且設計時都採取相對保守的水力設計係數,一般說來生物處理系統的水力負荷穩定性都很高,然而,由於進流水來源種類繁多,且對短時間高濃度的廢水排放無法預防,所以當負荷突增或是毒性物質流入時聯合污水處理廠只能在生物處理系統「當機」之後得知,在生物處理系統回復正常狀態之前,勢必增加三級處理的加藥量以保持放流水質穩定,而所增加的處理費用又將提高聯合污水處理廠的操作成本。在目前廠商外移、工廠減產、廢水量減少連帶造成聯合污水處理廠收入減少的情況下,維持一個處理效率高且操作穩定的生物處理系統,實是目前工業區聯合污水處理廠最重要的工作。
This research main industrial district union sewage treatment plant because processing water volume big, also when design all adopts the relatively conservative water power design factor, in general biological treatment system water power load stability all very high, however, because enters the running water origin type many, also discharges to the short time high potency waste water is unable to prevent, therefore when shoulders suddenly increases perhaps the toxic material inflow unites the sewage treatment plant only to be able in the biological treatment system "when machine" knew afterwards, in front of biological treatment system reply normal state, inevitably will increase three levels of processing the Canadian doses to maintain the release water quality to be stable, at also raise the cost of the treatment plant. So, how to sustain a high efficiency and stability biological treatment system for sewage is the main task of industrial district sewage treatment plant.
