摘要

近年來，隨著工業的發展，廢水大量的排放，在一般的工業廢水中通常含有Pb、Cr、Zn、Cu、Fe、Hg、Cd等重金屬，而造成水體污染，因此瞭解廢水處理程序中重金屬之轉化與傳輸行為，而加強廢水處理效益。本研究利用朝陽科技大學Bardenpho 模廠培養之污泥模擬廢水處理廠對污泥中異營菌（heterotrophic organisms, XH）及硝化菌族群之氨氮氧化菌（ammonia oxidizing bacteria, XAOB）、亞硝酸氮氧化菌（nitrite oxidizing bacteria, XNOB）biomass的影響，求得廢水處理廠中重金屬廢水對微生物抑制率影響及微生物受抑制相關參數，相關數據可作為廢水處理廠中含重金屬廢水之動力參數基本資料庫及模式模擬。結果顯示，在異營菌動力參數方面於加入硫酸銅重金屬廢水濃度分別為0.1、0.3、0.5、0.7 mg L-1 XH之

A new modeling concept to evaluate the effects of copper and cadmium on the heterotrophic organisms (XH), ammonia oxidizing bacteria (XAOB) of nitrification activities, and nitrite oxidizing bacteria (XNOB) biomass. The oxygen uptake rate (OUR) was employed to measure the constants. The result has shown that, based on the hetertroph kinetics parameters, the concentration of the pesticides wastewater with Copper are 0.1、0.3、0.5、0.7 mg L-1 of XH, which inhibition rate are 2.60%、14.19%、21.42%、39.70%；The concentration of the pesticides wastewater with Cadmium are 0.1、0.3、0.5、0.7 mg L-1 of XH, which inhibition rate are 0.31%、9.50%、17.05%、34.12%，the value of μH is decreased with the increasing concentration of pesticides wastewater. For the concentration of Copper pesticides, the inhibition rate of bH are 17.52%、29.64%、56.37%、72.26%；For the concentration of Cadmium pesticides, the inhibition rate of bH are 13.68%、23.45%、37.38%、64.62%. The concentration of the pesticides wastewater with Copper are 0.1、0.3、0.5、0.7 mg L-1 of XAOB, which inhibition rate are 20.73%、24.49%、32.31%、54.75%；The concentration of the pesticides wastewater with Cadmium are 0.1、0.3、0.5、0.7 mg L-1 of XAOB, which inhibition rate are 18.22%、22.90%、23.29%、44.50%，the value of μAOB is decreased with the increasing concentration of pesticides wastewater. For the concentration of Copper pesticides, the inhibition rate of bAOB are 20.81%、53.09%、77.23%、98.02%；For the concentration of Cadmium pesticides, the inhibition rate of bAOB are 11.73%、50.89%、74.89%、90.59%. The concentration of the pesticides wastewater with Copper are 0.1、0.3、0.5、0.7 mg L-1 of XNOB, which inhibition rate are 21.75%、26.16%、67.24%、74.98%；The concentration of the pesticides wastewater with Cadmium are 0.1、0.3、0.5、0.7 mg L-1 of XNOB, which inhibition rate are 18.74%、20.66%、55.15%、62.11%，the value of μNOB is decreased with the increasing concentration of pesticides wastewater. For the concentration of Copper pesticides, the inhibition rate of bNOB are 16.75%、38.27%、61.04%、77.31%；For the concentration of Cadmium pesticides, the inhibition rate of bNOB are 16.35%、26.07%、49.65%、66.73%.
