化学氧化是废水生物处理前有效的预处理方法;那些难以进行生物治理的化合物可以被部分氧化,使其更易于进行生物氧化.
One of the major limitations with chemical oxidation is that oxidation reactions frequently are not complete (reactions do not proceed to CO2 and H2O).
化学氧化的一个主要局限是氧化反应经常不能完成(即反应没有进行到CO2和H2O的生成). Incomplete oxidation may be due to oxidant concentration, pH, oxidation potential of the oxidant, or formation of a stable intermediate.
不完全氧化的发生可能和氧化物的浓度,pH,氧化剂的氧化电位或稳定的中间产物的生成有关.
The danger of incomplete oxidation is that more toxic oxidation products could be formed. 不完全氧化的危险在于会生成毒性更强的氧化产物.
Chemical oxidation is not well suit to high-strength, complex waste streams. 化学氧化不是很适合用于高浓度且成分复杂的废水.
The most powerful oxidants are relatively non-selective and any oxidizable organic in the waste stream will be treated.
最强的氧化剂是比较没有选择性的,能治理废水中任何可被氧化的有机物.
For highly concentrated waste streams this will result in the need to add large concentrations of oxidizing agents in order to treat target compounds.
而治理高浓度的废水中的目标化合物时则需要加入大量的氧化剂.
Some oxidant such as potassium permanganate can be decomposed in the presence of high concentrations of alcohol and organic solvents.
而像高锰酸钾这些氧化剂,可以被分解在高浓度的乙醇和有机溶剂中.
