摘要： In the detoxification of waste waters containing nitrite ions by means of hydrogen peroxide the addition of hydrogen peroxide is automatically controllable by adding the hydrogen peroxide continuously or in portions with continuous measurement of the pH and stopping the addition when no further reduction of the pH is caused by it. By control of the hydrogen peroxide addition through the change of the pH it is guaranteed that sufficient hydrogen peroxide is added to reach a complete detoxification of the waste water while on the other hand there is not wasted hydrogen peroxide unnecessarily.
摘要翻译： 在通过过氧化氢对含有亚硝酸根离子的废水进行解毒时，加入过氧化氢可以通过连续添加过氧化氢或连续测量pH值来部分地自动控制，并且当不再进一步降低pH时停止添加 通过它。 通过控制通过pH的变化来添加过氧化氢，保证加入足够的过氧化氢以达到废水的完全解毒，而另一方面不会不必要地浪费过氧化氢。
