영문 초록

The standardized activated sludge for the biodegradation test of anion surfactants has been produced from the collected microorganisms in the soil and the wastewaters treatment plant. The activated sludge was kept under control of the pH, dissolved oxygen, microorganisms and inoculated the basal medium flasks with LAS and LAS mixed with heavy metals [Cd(Ⅱ), Cu(Ⅱ), Zn(Ⅱ)]. Based of results, the inhibition effect(%) of heavy metals in LAS biodegradation were 1. All 1% when LAS 30mg/l-Cd(Ⅱ), Cu(Ⅱ) and Zn(Ⅱ) 0.1mg/l, respectively 2. All 1-10% when LAS 30mg/l-Cd(Ⅱ), Cu(Ⅱ) and Zn (Ⅱ) 1mg/l, respectively 3. AlI 10-40% when LAS 30mg/l-Cd(Ⅱ). Cu(Ⅱ) and Zn(Ⅱ) l0mg/l, respectively 4. All 30-65% when LAS 30mg/l-Cd(Ⅱ). Cu(Ⅱ) and Zn(Ⅱ) l00mg/l, respectively And toxicity order of heavy metals to the microorganisms in LAS biodegradation were Cd>Cu>Zn in low concentration(0.1~1mg/l) and Cd>Zn>Cu in high concentration(l0-l00mg/l).
